Hope I wasn't that wanker haha. I'm doing 50/50 myself and I'm on day 82(not a meph, I'm contemplating ditching my msnl seeds for mephs next grow). I've mentioned my ratio a few times but I don't think I've ever advised it lol. It was the top end of the range on growweedeasy, and I definitely plan on going like 70/30 next time too.
I've been watering like twice a day for a couple weeks now. I mix a 5L watering can of nutes every night. My plant is giant and only in a 2gal smartpot so I top it off every now and then as well, opening the tent and giving her a little more food isn't toooo hard, but it is annoying. I do like looking at her as well though haha.
I've been thinking of getting hydroton to put on top of the coco because it's supposed to help prevent evaporation from the coco I think. I've got some growstones already that I think I might just spread over the top
When I started I found that this worked really well to get my seed started.
It’s a dome with a wicking mat that I picked up from Home Depot for about 10$. In my case I put the seedling directly in the rockwool and just placed it in the dome and the wicking mat maintained the perfect amount of moisture for the seed. But with this method there’s a chance that it can sprout upside down, so using the Mephisto germination technique might be a good idea. I simply had trouble when transferring the sprouted seed from the paper towel to the rockwool so I opted for direct planting instead.
Once the roots started poking out of the bottom of the starter cube I dropped that into a 2.5x2.5” cube and put it back dome on the mat until the roots poked through that cube as well while feeding ~12.5% - 25% of the amount of nutrient solution recommended for seedlings (particular to the line of nutes I’m using).
After the roots came out of the bottom of the second cube I filled my bucket so that the water level was 1.5” below the bottom of my rockwool with the hydroton in the basket (line up the top of your rockwool with the top of the bucket). Once that’s done, gently backfill the rest of the hydroton and you should be in the clear as long as your humidity is good. My tent seems to run very dry with DWC (25-30% RH) so I kept the clear lid of the dome on top of the bucket for an additional week or two while the plant really took hold.
Edit: a little more info
I would also say keep a very close eye on your PH throughout and have lots of air (bubble) going into the bucket as well. I used an air pump rated for a 60 gallon this one in particular and ran a hose from each pump into a T joint so that only one hose went into my bucket where I hooked it up to the largest round air stone I could find to get and get nice and even coverage.
Other than that all I really did was watch the amount of nutrients that I’m adding, trained the plant as needed, and tried to keep her happy.
Thanks for the info everyone, I really appreciate the links and input.
I guess i'm still stuck on the question though - is it (or at least, can it be) worth it to buy the higher quality LED or QB lights at this stage in the LED market?
From the Amazon page for the Electric Sky 300 V2, it has some built quality features I am keen on, but there is also this comment, which makes me wonder if it paying the few hundred extra bucks over another system would truly be worth it and if these sorts of claims are true -

​
The page goes into some data on this, but i've just gone through so many different claims at this point my head is spinning. I don't mind dropping 700 on a light IF it offers truly greater performance, build quality, durability, lifespan, quality and distance of usable light output, and these sorts of things. But i'd sure feel quite the fool if I dropped 700 on a light that I could pay another company ~300 for with all the performance of the higher end light or even more.

There’s
Kind Soil - https://www.amazon.com/Kind-Soil-Hot-Product-single/dp/B00S1HRLPQ
Which is a super soil you can get on Amazon. You’d basically put a layer in the bottom of your pot and pour some potting mix with light nutrients and then the roots of your plant will grow into the fertilizer when they’re old enough. I believe you can top dress with it as well.
Michigan M3 - https://www.m3michiganmademix.com/
I believe you can buy this directly from they’re website
KIS Organics Water Only Mix - https://www.kisorganics.com/collections/organic-soil-for-sale-bulk-potting-soil-mix/products/kis-organics-biochar-soil-mix
Can be bought through KIS website, I’ve heard great things about the BioChar mix but shipping is pricey
Build A Soil - https://buildasoil.com/products/living-organic-soil-malibu-compost?variant=44903445010
They have they’re own bagged mix as well, it’s similar to KIS soil although I noticed they’re shipping costs are lower
Sohum Soil - https://sohumsoils.com/product/sohum-living-soils-cannabis-craves/
It’s a living soil like the above 2 choices, although it can be bought in stores and online
(I’m going with a local company that makes living soils)
Aliki Gardens - https://www.alikigardens.com/shop/freyjas-mix
Based in San Diego, super helpful and fantastic soil that is water only.
PH is very important, get the cheap visual kit from amazon https://www.amazon.com/Splendid-General-Hydroponics-Indicator-Accurate/dp/B017XTG6CG/ref=sr_1_4?ie=UTF8&qid=1541357103&sr=8-4&keywords=PH+test+kit+general
&#x200B;
Mix your nutes at 50% of the recommended rate per Biobiz
Get in the habit of flushing, your schedule should be:
&#x200B;
Feed, Water, feed, water, Feed, flush then repeat
&#x200B;
Your pot should be drying out in 48 hrs, so you are either feeding or watering every second day
Read this:
&#x200B;
Weeks 1 - 3. Once you've started your seeds and they break the surface of the soil, they are in their seedling stage. The first set of leaves to appear will usually single fingered, followed by a second set that may still be single fingered or perhaps 3 fingered. Once that second set appears growth will start to accelerate as the new leaves provide more photosynthesis. This process will continue, more new leaves, faster growth. Depending on the type of soil in use, mild vegetative nutes can be introduced at week 2. By week 3 most plants will start to show their sex. Males will start to produce pollen sacks and females will display pistols.
Weeks 4 - 6. The plants are now entering a pre flowering stage. During this time the plants should exhibit explosive growth, often as much as a new set of nodes and 1" vertical growth a day. This is the time when they will gain most of their vertical height. Many people make the mistake of switching from vegetative to flowering nutrients at this point, assuming that since they see flowers it must be the proper time. This is incorrect. If the switch to flowering nutes is made at this time the vertical growth will stop and the plant will put it's energy into producing buds. If you need to keep your plants small, or want them to finish earlier, they by all means switch nutes at this point. But if you want to get the most out of your plants continue feeding vegetative nutes until you see the vertical growth slow and stop. Depending on the strain that will usually be sometime during week 5 or 6.
Weeks 7 - 9. By now vertical growth has stopped and the switch to flowering nutrients has been made. The buds will start to fill out and put on weight, becoming hard and tight. Pistols will start to change from white to brown, orange, red, etc. By now the plants will also have developed a strong smell. Toward the end of this phase the large primary and smaller secondary fan leaves will begin to turn yellow. This is an indication that the plant is moving toward the end of it's life.
Weeks 10 - 11. At this time flowering nutes should be discontinued and only plain pHed water fed to flush the remaining nutrients from the soil and improve the taste. Yellowing of the fan leaves will continue as the plant draws the stored energy from them. Eventually they will die and fall off. By the time that the smaller leaves that come from out of the buds will also start to turn yellow. Then it's time to harvest.
I know that many of you are thinking that the seed bank said the plants will finish in 8-9 weeks, so why are you saying they take 10-11? The claims made by the seed banks are somewhat deceptive. If you switch to flowering nutes at week 3 or 4 the plants can finish in the times the seed banks say but they will remain small and not reach their full potential yield. Years of growing by myself and others has shown that autos do best if you follow this time line.
Of course, there will always be variations depending on the strain, the environment, nutrients, etc. This information is meant to only serve as a general guideline.
&#x200B;
&#x200B;
&#x200B;
Your setup looks pretty good. I was wondering what zone you are growing in, or if you want to share your general geographical area? My climate is very dry and as soon as the vents kick on all of my humidity vanishes. I've concluded that I need to isolate a flow of air to only cool the lights, but I'm using Quantum board LEDs so they don't really rig up to existing inline fan housing for lights but if you are growing with HID, you can get your system into something like this where you can cool the bulb only and let your humidity from your machine remain unaffected.
What do you think?
Hey mate, thanks :). A bath sounds like an excellent place to do this tbh.
Parts list:
I have them all in F at the moment, I will either double up and have another tub for V (probably a much smaller one) or use the Lucas formula or something similar where it is the same nutes throughout the grow.
I have done similar methods perpetually but I had two res's - one F and one V. They weren't auto watering though, I dipped a can in and hand-watered from the reservoirs. That meant I could daily water but only mix nutes every 3-5 days. This is another step.
I really liked my V and F buckets so will probably go with that to be honest.
I have ironed out some 'gotchyas' already, so if you do do this PM me or post if you want any advice mate.
A 4” fan that is tuneable will be able to fill your needs

You’ll need to place it on the outside of the tent assuming your entire space is filled with plants. Luckily you can flip the fan either way to control the flow direction
Thanks for you input! We will for sure have to track each others grow being they are born the same day! Are you also growing in 5 gallon pots? My lights I have 2 pieces of Hydro Crunch 600W. It will be curious to see how both of ours match up!

Mephisto Skywalker Freebie Day 75. 135W
4000k3000k HLG QB. 24 Hrs.Soil, Coast of Maine Stonington - Stonington Granular Fertilizer, GH MicroBloom, GH CalMg, MOAB, GH MicroGrow , Recharge (Until day ~50)
First Mephisto/Auto grow its been a pleasure. Wanted to see how far I could get with the Stonington Soil admendment. Needed help starting in early flower, which was probably because I used half the recommended dose.
Looking to cut in the next 10 days, currently ~10-20% amber on the sugar leaves.
I have a 125 watt QB and a 2x2' tent, started it around half-way (measured with a Kill-a-Watt) and then gradually cranked it up over veg. It seems to go up to 150-160 watts! Mine is still around 130, because my lux meter says it's around 35k-40k lux, and there's not much point going higher than that with a 20/4 light schedule, since I'm not supplementing CO2. (Part of the canopy that grew closer to the light during flowering stretch and hit 65k lux got some light burn until I bent it away.)
If you get a cheap lux meter (I have this $20 lux meter), you can measure the actual lighting in specific places in your canopy and decide, based on DLI targets. This helps with both dimming the light and actual light positioning.
Here's a great write-up about using a lux meter as a plant light meter.
The fan I have at hand is a basic 4in fan by vivosun says 203cfm
https://www.amazon.com/VIVOSUN-Air-Filtration-Kit-Controller/dp/B06XFRNPR8?ref_=ast_sto_dp
I think with the proper AC/Ventilation and good Air Tube hoods HPS would work just fine. The HIC I mentioned https://www.amazon.com/Sun-System-Emitting-Ceramic-Fixture/dp/B00HBCV8TM/ref=sr_1_5?s=lawn-garden&amp;srs=3043915011&amp;ie=UTF8&amp;qid=1500201628&amp;sr=1-5
Would be good for a 3x3
All are planted in 5gal buckets using 6in net pots. Using this airpump (one pump per two buckets) and these airstones.
The only plant with roots coming out of the bottom of the net pod is the Sweet n Sour.
Test PH at 6.5 after adding in all the nutrients into each reservoir individually, holding approximately 4 gallons of water, which is the following:
I try to keep the water between 67F and 73F with frozen water bottles, changing them out every 8 hours. The current lights I am using are two KingBrite 240w 3500k QB at 50% dimmness currently running 24/7 about 2 feet above buckets.
If you need anymore information, please ask!
Spider is one of many HLG clones popping up left and right. They mostly use the same diodes, so the difference comes down more to build quality. Here is the cheapest one I have seen.. https://www.amazon.com/Samsung-LM301H-Dimmable-RED660NM-Quantum/dp/B07Z9V8KPD/ref=sr_1_2?m=A9UQU9ITAVB70&marketplaceID=ATVPDKIKX0DER&qid=1574027408&s=merchant-items&sr=1-2&th=1
That is what I paid for a HLG QB280 a year ago, for basically double the light.. crazy.
Here is a great channel to watch if you are interested in cutting edge grow light tech and see some tests.
