🎓 Reddit experts on electrical timers
The comments and opinions expressed on this page are written exclusively by redditors. To provide you with the most relevant data, we sourced opinions from the most knowledgeable Reddit users based the total number of upvotes and downvotes received across comments on subreddits where electrical timers are discussed. For your reference and for the sake of transparency, here are the specialists whose opinions mattered the most in our ranking.
I was in your shoes not too long ago, it's overwhelming! Here's a list of things that I bought, but I am not an expert so if others have better input go for that:
Equipment
Shop for whatever is cheaper, I have a huge heater because I had an extra one from before. I've read that it's not necessary but also have read that if you want them to breed you need to stimulate warm water. For now, I keep the heater off and leave it at room temperature of 72F. They seem very happy! Most important in my opinion, add plenty of plants and a marimo ball or 2.
Lastly, I'm unsure of the siphon, I think it's good to have a bucket and siphon just in case your water parameters are looking bad so you are prepared to do a water change. From what I read, shrimp have a very low bio load and should be able to sustain themselves. Make sure to do tests regularly.
EDIT I just read that this is your first aquarium, so here is a detailed write up:
Setting up your tank
After your tank has cycled
Please don't skip the important step of acclimating your shrimp! They are very sensitive to water changes and this ensures that they will survive.
Here are my water parameters, people have all kinds of ranges but this is what works for me:
I hope this helps... again, I was in your shoes not too long ago, it was really overwhelming. But after a lot of research I think my tank is in a good place :). Other users, if there's anything in my list that seems incorrect please let me know!
I've been taking ice baths for a bit now using plastic water bottles as reuseable ice cubes while filling the tub daily. I have a nice jacuzzi tub available most of the time that is great, but lugging the ice bottles around (my tub is on the 2nd floor, and my freezer is on the 1st floor) and having to re-freeze them every day can be a PITA - as well as having to use new water each day instead of the ability to recycle. My next solution is a chest freezer, which I intend to set up as soon as I am able.
A few tips from my research:
Two things:
One. That light is made for a refugium. A lot of people will say that it's "harsh" or "cold" - that's because it's not really made for humans to look at - it's not a "display light". It'll work just fine for growing plants (it'll work really well, actually), but it will lack a lot of the "warmer" colors that look good to human eyes. Finnex makes a few others that are comparable: Plantet+ 24/7 (adjustable colors/remote/timer), Ray (bright white light), Ray 2 (very powerful white light).
Ultimately the light you choose will depend on a few factors. What kinds of plants will you grow? How deep is the aquarium (more powerful lights are needed for deeper water columns)? Do you mind if the light is "harsh"?
Of those considerations, I'd put the most weight on the tank dimensions and the plant specifications. Trying to push light through 24 inches of water for a carpeting plant? You'll want a Ray 2. Have an 8-inch deep tank that you want to grow some swords in? Don't waste your money on anything fancy.
----
Two. That CO2 kit is a money pit and here's why:
So let's say you spend 25 bucks on the kit plus 15 bucks for some cartridges. That's an upfront of 40 dollars with a 15 dollars per month in perpetuity. That means that one year of this kit will cost you $220.
Instead you could go for this paintball setup for the same price:
That build adds up to $205, will be WAY less work in the long run, much more stable, and simply easier to run. Also if you ever get sick of it and want your money back - it'll retain a lot of it's value. You could probably re-sell that whole set for 170-ish used. Also, that tank will last you a good few months before needing to be refilled.
CO2 can really help your tank flourish, but it takes a considerable buy-in. Go all the way or go home. Half-assing it to save money on sub-par equipment will just cause you headaches and a lot more money in the long run. I spent about 250 on my setup two years ago and haven't had to spend a PENNY on it since.
----
PS: /u/Elhazar, are you really gonna go around using the little 2 in "COâ‚‚" and pretend like it's nothing? Well aren't you fancy!
I have the 20-27" NICREW light for my 10 gallon low-tech planted tank and it seems to work well in keeping my plants alive (mostly anubias, amazon swords, and mosses) even though the lighting is on the low side. You MIGHT be able to grow medium light plants with this, but high light plants are a no-no (believe me I tried). Because you have a 20 gallon, go for the 28-36" one. Everything else seems good. Also, you might want to buy an automated timer like this one for your lights https://www.amazon.com/Century-Plug-Mechanical-Timer-Grounded/dp/B00MVFF59S/ref=sr_1_4?ie=UTF8&qid=1504061029&sr=8-4&keywords=timer+light. It can be quite tedious trying to turn off and on the lights for your plants each day. Remember plants need around 8 to 12 hours of light per day.
The rock wall looks cool! You can definitely try it out if you have the time. Also try to add some plants first when you cycle, as plants can help speed up the cycling process!
Good luck on your tank :)
​
Setup (in case you want this extra guide):
​
It ain't cheap and won't likely solve all your algae issues (i have all manner of thread algae currently but it comes and goes) but it makes all the difference in overall plant health and growth, you will be trimming weekly if all goes well.
Success, now just wait until the plants get wildly healthy in a week.
I actually ordered everything individually from Amazon. I’m sure you could probably find everything locally as well but it was easier for a newbie like me to get it all from the same place.

Again, total newbie and this is the bare minimum of quality and price I was comfortable with. I plan on upgrading to a bigger tank and a better regulator in a few months. Do your own research too.
Most recipes will probably be fine with an additional 2-4 hours. Crock pot recipes aren't very fussy. But that counts more for beef than chicken, because chicken dries out easier. A couple tips:
For chicken, use thighs instead of breasts. The thighs have more fat and will keep from drying out longer. And yes, chicken can still overcook and become dry while in a sauce. It's just less noticeable.
Beef will probably work great it's a bit more forgiving than chicken.
One other solution many people here do is to buy a timer you plug your crock pot into like this. That way, you can program it to turn on 4 hours after you leave. And especially if you're using frozen dump recipes this is a great solution.
Or I'm sure there's programmable crock pots you can buy to skip the plug timer.
a cheap hps kit is a good start. Can grow plants through all stages. Just need a decent sized space like 6' tall, 4 x 4
want to spend more / better quality? get a cmh kit.
want to diy? build a LED COB kit
looking for more shelf compatible that are good for seedlings? get LED shoplights at your local lowes / depot
yeah you will want a timer. they are cheap / normal timers u see for like christmas lights
If you’re sure 15 minute cycles are good, then mechanical timers work great and are super easy to program. I’ve used these in the past:
Century 24 Hour Plug-in Mechanical Timer Grounded https://www.amazon.com/dp/B00MVFF59S/ref=cm_sw_r_cp_api_cqeYzb0HS34MQ
However, except price, digital timers are pretty much better in every way. I once had an issue where 15 minutes was too long for an ebb and flow I built. Pump was too strong, overflow didn’t drain fast enough. I switched to digital to do a shorter interval and the problem was mostly fixed. Not exactly a common scenario, but for a couple bucks extra, the convenience of digital can certainly be worth it.
Steels are fun and all but you seemed to develop a delay after the first shot. You got in the habit of firing a shot and holstering. This became evident when you missed on the last steel.
I would suggest two or three things;
If this is your 'carry' gun, it's a serious tool that you expect to have to possibly use in defense of life or safety of you or those you care about; a responsibility.

This is my setup, my fan is coming in today and my seedlings sprouted this morning. I did quite a bit of research and The light is a little underpowered but I was on a pretty tight budget and can always add more light later.
I spent $40 on seeds and super soil mix from Mephisto genetics, going a more organic route and won't require nutes.
I also spent about $30 on peat moss, perlite, and compost. I already had some ducting and pots.
As /u/king_human stated:
Alarms:
Harbor Freight and other stores, sell inexpensive alarms you can put on your doors and windows. http://www.harborfreight.com/wireless-door-and-window-alarm-92745.html
Motion sensor lights http://www.harborfreight.com/36-led-solar-security-light-69644.html
Security cameras you can hook up to your computer. You can even get a web cam to do the work. http://www.harborfreight.com/weatherproof-security-camera-with-night-vision-47546.html
Always go with a camera featuring night vision.
If you've got more cash, a professional security service and/or more expensive camera system that emails photos and sends alerts. Some baby monitors do this as well.
Put various lights (and tv or radio) in the house on random timers. http://www.amazon.com/Watchdog-Guardian-House-Sitter-Radios/dp/B00H5A8QDG/ref=sr_1_4?ie=UTF8&qid=1413568449&sr=8-4&keywords=random+light+timers
Don't put empty boxes of recent purchases out in the garbage. It's a great way for thieves to see that you just got a new TV or computer. Likewise, don't carry in valuable or expensive purchases within site of anyone. Pull in and shut garage then unload the car.
Indoor motion sensors on your lights are good too. They walk in and a light goes on, they might just bail. http://www.homedepot.com/p/Westek-360-Degree-Indoor-Motion-Activated-Light-Control-MLC9BC-4/202524824?N=5yc1vZc32r
Dogs are great. I have a two. Not everyone can have them, but they're a great deterrent. If you can't get one, put out dog bowls and leashes. Put those emergency pet stickers in highly visible locations. More subtle than a fake 'Beware of Dog' sign. http://www.amazon.com/SAFETY-234001-2-Count-Static-Window/dp/B00079YTTC/ref=sr_1_1?ie=UTF8&qid=1413568825&sr=8-1&keywords=emergency+pet+sticker
Keep purses, computers, keys and other important/valuable items, out of site of windows. Make the thief work to find what they want.
Engrave your valuables along with recording via picture and serial numbers which comes in handy for insurance claims. http://www.harborfreight.com/electric-engraver-46099.html
Check your house for unscrewed/burned out light bulbs, things you can see from outside and remedy those items.
Deadbolts are your friend, but make sure they're installed properly.
Replace glass in sidelights, low windows and doors, with shatterproof glass if you can afford it.
Arm yourself. If you have crooks bold enough to break in while you're home, who knows what they will do. Be prepared.
You've been hit once, it wouldn't be unlikely you'll be hit again unless you make it harder for it to happen.
Well, I'm skeptical of the smart home stuff for two main reasons. The biggest is because most of it seems like either more fragile and less reliable than the good ol' mechanical stuff. I know a light switch is going to turn on and off my lights. If it doesn't, odds are it's a problem with the light, not the switch. If I say "Hey, Lady in a Tube, turn off the lights," there's a much bigger chance of it not working in a way that I can't do anything about. A lot of other home automation stuff seems like it could be just as easily, and a lot more reliably, done with a simple, mechanical outlet timer. I want hot water in the morning, why buy a smart kettle or a smart plug that needs Wifi, when one of those timers will do the same thing, more reliably, even if my internet is down? Then there's the issue of so many of these smart home gadget companies getting bought out and bricking their devices. No fun.
The second concern I have is, of course, privacy. These things are collecting a lot of data, and I don't know how a lot of it is being used. I'd prefer to not have a hot microphone picking up what I say and sending it to a data center to be picked through for ads. Yes, I know the Echo doesn't send any audio unless it's been triggered first, but I don't know what all these other devices are sending out. Wasn't there a smart vacuum that was uploading maps of its users floorplans? Then there's the Vizio smart TVs that literally uploaded a framegrab of everything it displayed to Vizio every 30 seconds. I might be paranoid, but until the privacy stuff shakes out, I ain't gonna bother, even if I can find a use for it.
Ok, here is my build list minus a couple things that I bought locally.

If you are going to be doing it a lot, just get one of these. Though they are not super cheap. A phone app won't work great indoors with other people shooting. But then again, try an app first. If it works, cool.
I have one of these, and it is nice to be able to dial the sensitivity down, and the super loud beep to start a drill at random is nice. Also I clip it to my center mass on my belt.
Anyways, good product. Not cheap

When you boot it, it says COPYWRITE 2014... So that gives you and idea about how this industry is really pushing the edge here.
However... Despite not doing any sort of continuous evolution, it works pretty well.
In a shot timer you want loud beep, and adjustable sensitivity. This does both. There are a lot of options but you want it to work. I haven't had much luck getting it to work for suppressed guns unless the microphone is held stupid close to the timer.
YMMV, but I like this one well enough. And good on you for getting a timer, they're REQUIRED to get better.

Obviously you can find other stuff if you like but that's my setup and is working perfectly. No noise, no smell, nothing except two beautiful plants. You'll need a couple of other things like nutrients, thermometer and a hygrometer, but they're dead cheap and down to personal preference. Head over to r/microgrowery and look at the side bar for more information. www.growweedeasy.com and www.420magazine.com have also been invaluable to me.
Don't be intimidated by all the initial research and leg work necessary, it's pretty easy once you get going and the benefits massively outweigh the effort.
For the lights it would probably be easiest find what ever grow lights you want to use to just set them up on a outlet timer like this one

The watering system is harder to do.
How big are the plants?
Do you have an idea of how the plants will be arranged?
Are there any other physical limitations like space or if it has to be mobile?
What is the water source like? A bucket? A garden hose?
Also how much experience do you have doing anything DIY?
Thanks for the suggestions everyone. It looks like this does exactly what I want in one package, so I've ordered it: https://www.amazon.com/gp/product/B07DFT2WDS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Hopefully it'll work well!
best option is to see if her insurance will cover the installation and monthly service for a medical monitoring device. like life alert or similar. if they DO, then reach out to a couple alarm installation companies.
any residential alarm system can be configured exactly as you're describing. the advantage being that there's live monitoring so if no movement is detected within X hours, the monitoring company will call the home and if nobody answers they can dispatch EMS.
added bonus is you can get personal assistance devices like neck lanyards or wrist straps that would give your mom a button to press if she ever slipped or fell.
with insurance covering the bill, it's a win-win. if medical insurance won't cover it, look into her home owners insurance, often they will give you a deduction for a monitored alarm system, that can cover the monitoring bill. and then you'll only be out a few $100 for the install.-

if you want to do it yourself, you don't need programming.
motion sensors provide a NO/NC pair of contacts, that reverse state when motion is sensed.
combine with 24 hour timer such as :
https://www.amazon.com/DROK-Controller-Delay-off-0-01s-9999mins-Switching/dp/B07DFT2WDS/
every time the motion triggers, reset the timer.
if timer expires it closes a pair of contacts on your monitoring device.
it will take some shopping to get exactly what you need, but you get the idea.
honestly though, you'd want a 12 hour timer. 24 hours is a long time.
I don't have super helpful advice as I don't have the space for a large collection. I use my lights year around, tho I truck my plants outside as much as possible during the summer.
I have these bulbs.
And I just pop one into a desk lamp, which is plugged into this automatic timer.
The timer does have a slight learning curve to it, but it's so nice to have something that does all the work of turning my light off and on.
The bulbs are great and cheap. I usually rotate my plants closer and further away every other day or so. I find if I leave them directly under it (about 5-6 inches away) for too many days, they will skip right thru pretty stress to ugly stress. In the dark depths of winter, I might pull out my red and blue light gooseneck as a supplement to make me feel better, but I really don't think I'll need it, and that usually has to be within 2-3 inches tops to be any good.
awesome, thank you! would a timer like this work? https://www.amazon.com/dp/B00MVFF59S/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B00MVFF59S&pd_rd_wg=KBcJh&pd_rd_r=0JGTM74FGMQ0YW91K08Q&pd_rd_w=5pAEd
Thanks for the suggestion! This would be a great feature to build in once I finally incorporate a microprocessor. Here is what I’ve suggested to others wanting a simple solution to this: Century Smart Digital Countdown Timer https://www.amazon.com/dp/B01D3QEK4E
At the moment it is nothing simple, I have a ViparSpectra 450w w/ bloom switch hooked up to a Century Timer. I just went and bought a small circular fan maybe 6 inches in diameter at Wal-Mart and tied it up in the tent to the top vent as an exhaust. It's in a tiny 2x2x4 Tent. I have a couple clones from my outdoor grow, 2 in pot rn and a few more in a dome, all in the same tent. Not obviously going to keep them all, just hoping the pick the best of the litter.
If you have an automation hub, I think that should be able to find a zwave power strip or wifi plug to have the iron or an ext cord plugged into and then setup a rule that ok not leaves power on once it starts. Just checked my Wink and I can create a robot to do this.

Here is my current (year-round) setup! I moved into a new apartment with only north and west facing windows, and nothing was getting enough light. So recently I upgraded my setup.
I have the lights on for about 12 hours a day.
I used to have a clamp lamp with CFL, and that worked for a bit, but I was trying to squeeze too many plants under it so they started to get etiolated. In comparison, these lights are amazing. You can see that some of the plants were etiolated but are now growing compactly!
If you have amazon, order one of the timers like this one. I have one for my tank, and it's great! The lighting stays consistent and is one less thing to think about. I regularly am gone on the weekends without feeding, and my fish are all plenty fed. If you're worried, just feed them a bit more than usual on the last day you're there. I would definitely drop a sheet over the tank to keep the dust out.
I have the vacuum version Ranar and it's been a good unit except for the electronic timer.
The smaller unit would be perfect for my shop. In 6 years I've only needed to burn 3 larger screens. 1 for a customer and 2 for me doing some midnight political sign work.
If the twist timer was more accurate it would be sweet. I had to replace the electronic one on mine and Ranar wanted $80 for it. I got a Chinese one from Amazon. Was $15 when I got it, did take a little figuring out but has worked flawlessly.

Hey guys,
​
I saw this awesome video by Derek Gilman about an automated curing system he had built: https://www.youtube.com/watch?v=Jho0qeTUZnA
​
His rig is with 5 gallon gamma lid buckets, and he loads about 2 pounds in each one. The way the system works is you put your dried bud in the buckets, and you hook up an air pump to the buckets, on a timer. The timer I have set is for 15 mins every 24 hours. (The timer kicks on the pump, pushing air through the buckets, and auto shuts off after 15 mins). You install little valve outlets on the container and they exhaust out the old the air when the pump comes on, and then seal back up when it shuts off.
Being a micro grower who grows autos that yield ~100g, at about 179 grams a gallon I would be nowhere close to filling a 5 gallon gamma lid bucket, and even at 2 gallons I'm still a bit short.
So, I went to the store and found 1 gallon airtight food containers and it works! I was able to fit a Seedsman Zkittlez Auto I just got finished drying/trimming and ready for cure.
The system I built is:
- Aquarium Air pump, ideally with a built in manifold so you can hook up multiple containers: (NON AFFILIATE LINKS!) https://www.amazon.com/gp/product/B008ILGHAU/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
- Air line https://www.amazon.com/gp/product/B000255NYQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
- Check Valves: https://www.amazon.com/gp/product/B07FKJXZ78/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
- 3/16" Drill bit
- 1 Gallon airtight food storage container https://www.walmart.com/ip/Better-Homes-Gardens-Flip-Tite-Square-Food-Container-16-Cups/370961661
- Timer with 15 min increments: https://www.amazon.com/gp/product/B00MVFF59S/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1
​
I noticed that the pressure was a little too high when I had only one check valve as the outlet and it was causing the lid to pop up, so I added two more. If you are growing photos, you're most likely yielding more than I do with my auto plants, so you'd prolly be able to just use the 2 gallon gamma buckets, which should hold about 1/2-3/4 pound. https://www.amazon.com/Gallon-Black-Bucket-Screw-threaded/dp/B018BFY2KY/ref=sr_1_5?keywords=2+gallon+gamma&qid=1574473805&sr=8-5
A bale of cocogro or cocotek, some CannaCoco A&B or BioVega+BioFlores for organic , some Garden Lime from Lowes, a tent, an led, a light timer, a carbon filter and fan, and a guide book.
Ask Ed's coco guide works well for basics
Micks Coco guide is also good using just MaxiBloom
I don’t mean to be cruel but i am laughing at your head-slapping moment!
Had a similar one, but it was only imaginary. Wanted to energy conserve by shutting down my cable modem when not home. Mostly researched LTE 4 sorts of switches, none really hit all cylinders / price to use case never made it.
Did end up buying this:
Woods 59746WD Outdoor 24hr Photoelectric Timer with Wireless Remote Control Kit, 3 Grounded Outlets, Weatherproof, 80ft Range https://www.amazon.com/dp/B00E5VEBK0/ref=cm_sw_r_cp_tai_2TeOAbEBKEC51
I use two of these in the bottom drawer. A little spendy for a 140mm fan but I liked them plugging in via usb. I also have them on this timer. 30 min on and 30 min off.
Hey the pocket pro I is $99 from amazon, $96 from third party sellers. I was trying to post it to r/gundeals but I guess they don’t allow amazon posts. https://www.amazon.com/gp/offer-listing/B008KMOSAI
You're better off buying a light timer like this or just having the light on 24/7
Programmatically turn it on/off only, or also be able to toggle it freely remotely? If you only need it to turn on/off at certain times, $8.99
Here is a link to a random one https://www.amazon.com/NatureBright-SunTouch-Light-Therapy-package/dp/B000W8Y7FY.
Then they have those things to plug into outlets to make the thing plugged in operate on a timer. Here is an example
https://www.amazon.com/Century-Plug-Mechanical-Timer-Grounded/dp/B00MVFF59S/ref=zg_bs_495340_1?_encoding=UTF8&psc=1&refRID=35SVFS2GRDGP54NJ5VBV
I saw someone suggested a sunlight alarm clock. If you end up getting one, I’d love to know how you like it. I’ve been thinking about getting one.
TLDR: Keep out of direct sunlight and you should be all good.
Good question but I bit complicated the way you asked This can be a bit controversial but I come out on the side of "snakes don't need UVB light." There are some that will assert that certain breeds do better wtih UVB but I am skeptical of those findings. Anyway you look at it your snake should not be put in direct sunlight. You can't control the sun with a thermostat and on a sunny day the sun could make the enclosure dangerously hot. I like to keep my snakes on a 12/12 day/night cycle. I do this with a standard light timer. Many people would be totally fine with just natural light and as long as you keep the snake out of direct sunlight I think this is a good option. As for your heating. I don't like heat lamps. In my experience they suck humidity out of the air. Humidity can be a problem for people who use aquariums even without a heat lamp.

Connect your grinder and water kettle to a timer so they turn on at 4:28. When you get up, pour the ground coffee and water into the French press, brush your teeth while it steeps, plunge and go.
So this would require you to buy a timer, but that's cheaper than a good drip coffee maker. You'd have to set up the beans and water the night before, but you'd do that with a drip machine anyway.
I bought this
And it’s been amazing.
I have a Chicago Electric fd60-u2 that has 2 outlets and has done well for me. Here’s one like it, Century Heavy Duty Mechanical Timer Dual Outlet - 24 Hours https://www.amazon.com/dp/B00MVEMD76/ref=cm_sw_r_cp_api_gld8BbFD8GVX2
I have this 4 foot T5 with a stand, this shelf on top of a side table, this 2 foot T5 hooked to the bottom shelf with paper clips and key rings (lol), daisy-chained to this other 2 foot T5 hooked to the top shelf the same way. They are all run on two of these timers which are on ~10 hrs/day.
I have two of these plant racks from Lowe's in front of my south and east facing windows, I jimmied out the bottom shelf and sort of rested it on my windowsill and the edge of the stand (lol again). It's all very MacGuyvered.

this is the one that I have and use on my bedside lamp https://www.amazon.com/Century-Plug-Mechanical-Timer-Grounded/dp/B00MVFF59S/ref=sr_1_4?ie=UTF8&qid=1505316483&sr=8-4&keywords=outlet+timer
but the dimming featured alarm clock sounds heavenly
I’ve had the pocket pro for about a year now and it has been flawless.
I only batch sparge and thus can't comment on the fly sparging method, but I will offer the advice of picking up a remote controlled outlet such as this one for turning the pump on and off. For me, it made a world of difference in ease of operating the pump.
Amazon has one here for $10!

+some hoses / tubes / enclosure for your electronics and a few hours of your time.
you should be able to construct a nice system for 50-100 dollar
Erm... maybe attach a simple motor to a Wall timer?
If you don't know electronics, then you should accomplish this with as little electronics and as many off-the-shelf parts as possible.
Oh, that's nice! You can load the washer in the morning, set it to start running at an hour before you usually get home, and then move it to the dryer right away.
​
I wonder if one of those[ outlet timers](https://www.amazon.com/Century-Plug-Mechanical-Timer-Grounded/dp/B00MVFF59S) would work for that? You'd need a grounded one that accommodates the three prongs (the one I linked does).
work smarter, not harder
You can get something like this:
https://www.amazon.co.uk/Defender-Segment-Timer-Switch-Plug/dp/B01CP44AU4/ref=sr_1_4
It is essentially a timer for your socket (it's UK obviously but I assume it's a fairly international concept) - just leave your heater plugged into it, turned on and set up the timer to turn on at 4am so by 5am it's warm in there.

look for something with a 15-20 amp capacity and you will be fine.
​
does the ac start up if you leave it running, unplug it, then plug it back in? if a timer will not work for anything but to shut it off in the middle of the night.
​
whats wrong with running it all night to be comfortable?
I think i can make out "intermatic" on the left piece. Quick Google search looks like they make lighting timers.
See here : Intermatic EJ500 Indoor Digital Wall Switch Timer https://www.amazon.com/dp/B0088LMEVQ/
This would work:

You can probably find them at any major hardware store. Make sure it's rated for 15 amps (usually marked heavy duty).
I use a standard SPST NC 12V relay and a 12V timer to shutdown the RPi gracefully once the ignition is switched off. The solution is based on this youtube video - https://www.youtube.com/watch?v=rknBevexOcU&t=554s)
The timer powers a 12V-5V converter (which in turn powers the RPi and external USB hub etc.)
​
Setup diagram - https://imgur.com/a/o64l4gW
​
The timer is connected directly to the battery as well to the IGN line. The 12V - 5V converter is connected to the output of the timer. When IGN is on the timer switches on it's output which powers the 12V - 5V converter. When IGN goes off the timer starts it's countdown (e.g. 10 mins), when complete it switches off the output (and the 12V - 5V converter switches off). When the timer is off it draws a very small current.
To enable a graceful shutdown of the RPi (i.e. for the RPi to shutdown before the timer) I use a standard SPST NC 12V relay (connected as per wiki posting - https://github.com/opencardev/crankshaft/wiki/Boot,-reboot-and-shutdown-the-Pi-with-ignition-key). Pin 86 is connected to the IGN line, pin 85 to GND, 87A to a GPIO pin (e.g. 23) and 30 to GPIO GND. A script on the RPi is monitoring the status of GPIO 23.
When the IGN switches off pins 87A and 30 are connected sending GPIO 23 low. The RPi will power off after the shutdown delay (this should be less than the shutdown delay for the timer - e.g. 9.5 minutes).
​

This has 5A output which is more than enough to power the RPI, screen and a powered USB hub (for high speed charging of my phone).

I like the mechanical timers for their simplicity, they seem to last fairly long. I have owned a few of the digital timers and they can be a pain to program correctly. Even though the mechanical timers can't have multiple schedules it is nice to know they'll function just as intended.
Here's one I'm talking about - https://www.amazon.com/Century-Plug-Mechanical-Timer-Grounded/dp/B00MVFF59S/
I'd go low tech with this.
Get a plug in appliance control module. Something like this (but whichever one will work with your system; if you have no smart hub get a mechanical timer like this one).
Wire the 24vac transformer that feeds your doorbell in through it.
Result- doorbell does nothing for the hours you specify, for under $50.
Alternatively, get a double pole relay and a small interval timer. During the day, pushing the doorbell rings the chime. During the night, pushing the doorbell opens an electronic valve that feeds a sprinkler head pointed at your front door for several seconds. If drunk college students are ringing your doorbell at night, they will quickly learn not to.
I have the same ones, they get really hot so be sure to keep the heads far from the seedlings
Might even consider getting a mechanical timer. I got one recently and now I dont have to worry about turning them on in the morning and off at night.
I don't know how much power your ozone generator draws, so this might not be correctly sized, but a time-delay relay is what you want.
If I were you I'd time how long it takes for your board to reach 85-90% and then get something like this so that it just cuts of the power.

Get a Christmas light timer for your electronic devices. When the time runs out everything shuts off.
The one linked might make noise, but you can invest in digital timers too.
I have lights on mains socket timers at the back and front of the house. They switch on before dark then switch off at bedtime, so even if I'm late home the house still looks occupied.
A cheap mechanical timer can be configured for an endless 15 min on/45 min off.
You are looking for a short cycle timer. They are all expensive.

Use an SCAA certified brewer plugged into a digital outlet timer.
About 30 minutes is right for small miniatures for me. I use the same Elegoo Resin as you in gray. If its a large bust or something I will do 45m to 1hr.
I use this timer (well, the old version): https://www.amazon.com/gp/product/B01D3QEK4E/ref=ppx_yo_dt_b_asin_image_o06_s00?ie=UTF8&psc=1
I would so it on low for 6 hours. If your crockpot doesn't have a timer and you want to start it before work, I suggest getting one that the plug goes into. 8 hours is a long time for veg.
They make digital ones, but you have to reprogram them Everytime you plug it in. Here is a link to a mechanical one. https://www.amazon.com/Century-Plug-Mechanical-Timer-Grounded/dp/B00MVFF59S/ref=mp_s_a_1_4?ie=UTF8&qid=1536151828&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=plug+timer&dpPl=1&dpID=41hWDwaWyhL&ref=plSrch
i use those basic ass dial timers , i think you can get one for like 10 $ mine has tabs you push in / pull out and can be set for either on/off every 15 mins. .

Couldn't you use a normal time-dependent timer between the inkbird and your kegerator? That way your kegerator will only kick on during the times you tell it to.
Edit: Not that easy. Power needs to be supplied 24/7.
Double Edit: They make ones with a battery back up.
I bought this:

Set it and forget it!
It's pricey, but it's the same brand used in IDPA/USPSA sports, so you're getting quality. I used an app for a while before buying this (buy once cry once)
