u/legalpothead · 20 pointsr/trees

A bit over 2 oz per plant cured bud (plus a decent amount of low grade cannaoil from the leaves), so 12 oz+ per year. I have a small grow tent, and I use a Marshydro 300.

u/firecrackerrock · 10 pointsr/SpaceBuckets

Lights: I have the mars hydro 300 (132 true watts) as my main light on the top, and plan to add a couple strips for side lighting in the near future.

Ventilation: As you may see from the pictures, I have the heat exhaust on the top side. The exhaust is being pulled into a secondary tote. In the secondary tote I have a large carbon filter attached to a 6 inch inline fan with variable speed control. This kit. Definitely overkill but I like the room for expansion.

I plan to start growing in a 3 gallon smart pot knock off, with some ak-48 autoflower seeds.

I have really enjoyed watching this community grow through the years.

Thank you everyone for your wonderful contributions. Guys like /u/Ekrof, SAG, /u/Halfmpty, /u/exactly25smeckles, and the rest have really inspired me to try this for myself.

I would like to add some filtration to my passive intake, any suggestions?

u/atpcjm · 8 pointsr/microgrowery

I wouldn't bother with those lights. I was on the exact same boat as you a couple of weeks ago. Skmood1 actually pointed me in the right direction.

I'm not sure what your budget is, but you may want to look into COB LIGHTS. They are 1000 leagues better than the viparspectra and all those LEDS in the same tier. They use pretty old tech apparently.

I just started to learn ins and outs of LED, if I'm wrong here, please correct me
Lets take a look at a couple of the numbers Vipar provides (last picture on amazon). Looking at their spectrum sheet, right off the bat the light you selected will under perform where it matters, flowering; buds. It lacks a good deal of red spectrum light. However with that said, it'll be a decent light for veg, worth it? No, but decent. I won't say worth it, because now you want to look at efficiency and lumen per watt. Efficiency in terms of led is basically how much light is produced versus heat from your LED panel.
The Vipar has a pretty shitty efficiency, it loks like you'll be prducing 67% of heat vs 33% of usable light. With COBs, you can essentially choose your own, going all the way up to 70% light. With lower efficiency, you'll get more lumen per watt (more light, I guess?). The next step up are Quantum Boards, but those are always out of stock!

Just a heads up, COBs are generally more expensive outright, and there maybe a little DIY involved, but it totally worth it. I was running the 600w viparspectra PAR series for 2 weeks, and my seedlings grew about 3 inches. I moved over to a 2 cob array (less power than my vipar), and in 1 day I see 2 new growth leaves, both plants grew at least half an inch, I was blown out of the water.

P.S.- this one looks better: Mars Hydro 300w
https://www.amazon.com/MarsHydro-Spectrum-Certification-Hydroponic-Greenhouse/dp/B00XC3LBI2/ref=pd_lpo_vtph_86_tr_t_2?_encoding=UTF8&psc=1&refRID=FHW46JTAZPEMSK6H1VS4&dpID=51clUyqI-5L&preST=_SY300_QL70_&dpSrc=detail

Check out the spectrum chart! Good luck and have fun. I killed sooooo many seedlings, purchased sooooo many unnecessary things, but the people here helped me every step of the way. You're in proper hands.

u/SpunkAlarm · 7 pointsr/mildlyinteresting

It's led grow lights with bulbs in several different spectrums, like this. OP is growing the dank in his closet.

u/skoomd1 · 6 pointsr/microgrowery

8-12 plants in that space is not gonna work. I would do 1-2 if you wanna scrog and 3 if you're not. And those are max amounts. Realistically 2 is already pushing it.

And those lights really are garbage man. Get a refund if you can asap.

For your size tent/room I would get either 2 of these


1

or 2 of these

u/crispleader · 6 pointsr/HotPeppers

If you want blurple lights, the MarsHydro is a go to. T5 and T8 fluorescent bulbs/fixtures are a usual grow light suggestion.

How many plants do you want to support? What stages of growth?

I used the Mars Hydro 300 watt LED.Available at Amazon.com on some clones I got back in January.Built a small grow box till the were ready to go outside and they're doing great,I live in western Washington but I would think the same technique would work for you.Put them on about a 20 hour light cycle and move them outside in about a month.http://www.amazon.com/MarsHydro-Mars300-Spectrum-Hydroponic-Greenhouse/dp/B00XC3LBI2/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1464310100&sr=1-Tho1&keywords=mars+hydro+300 This is how how you help people,thoreau.Not with stoopid remarks.

u/Cuicos · 4 pointsr/microgrowery

Lower end led grow lights do list lumens and/or actual draw often but since they're commonly purplish lights lumen readings are low, lumens are for visible light, not for plants.

What you want is PAR wattage or PPFD, but mostly higher end LEDs list that, although a low end Mars 300 does too, says "300" because all diodes driven at max would draw 300w but most underdrive them upwards of 50%, and some like this one I mentioned list lumens, and also PPF actually. Most that don't list PPFD are white lights and may list lumens, if they don't list actual draw don't even bother with those.

Incandescent watt equivalences are mainly for CFL bulbs, screw on LEDs list CFL watt equivalences I think?

u/mac_question · 3 pointsr/microgrowery

Panda film draped over the back just for purposes of this picture; other side is reflective white & will be used to cover the whole shelving unit.

Shelves are 30" x 14" by 60" high. Lights are each Mars300's. Air pots are 1' cubes, about 7.5 gallons each.

Did I get the wrong pots? I'm also thinking of maybe using ratcheting straps around the shelf poles to hold the containers in place better, maybe scrunch 3 together by extending the bottom shelf a bit.

Other thing: the panda film. I'm thinking about trying to glue or epoxy magnetic stripping on some to create a removable panel, but I doubt the magnets will hold well.

Any feedback or ideas appreciated!

u/rleech77 · 3 pointsr/microgrowery

Hey dude - I'm in the middle of flower on my first grow and think I can help out a bit here.

Not sure if you're already on this site but growweedeasy.com is an incredible free resource

You could easily do one plant in a tent like this or go bigger and do a 48" x 24"

As for LED's in that range, most people seem to like either the mars hydro or viparspectra (I'm currently using an mh/HPS light)

Enjoy!

Personally I like soil. Easier to diagnose and remedy in my opinion. Can't cheap out on the soil though. Fox farm gives good results and can be found at almost every nursery or online.

If you can squeeze any extra money out I'd put it into the lights.

Also check the side bar and all this stuff can be found in there. I just smoked so I'm feeling especially helpful lol.

Anyway remember it's a weed and will grow you just have to have the patience to let it. Also remember to have fun.

Good places to start.

u/ttmmm2001 · 3 pointsr/Hydroponics

Have you verified these are ACTUALLY 54 watt?

There is an epidemic of LED retailers straight up lying about the power on their lights.

Lights will often advertise at 50 watts for instance when it actually pulls 12 watts, or something. When cornered on it, they skirt the issue by saying it's "equivalent" to a 50 watt traditional bulb.

It's bullcrap, its a big problem, its very hard to avoid.

When considering an LED light, i always read through comments until i find someone who threw it on a watt meter to get an actual wattage.

​

Like others have said, plants only need a few things. Nutrients, water, light, and CO2.

Seems like the missing link here is the light.

Here's the light i bought, and have had pretty good luck with it:

u/WhiplashOne · 3 pointsr/microgrowery

Get a better light, dude. It's the one thing that directly correlates to yield. You got all this awesome stuff (tent, filter, plants with good genetics) but have a light meant for a closet bagseed grow. Go with something like this and you've got a much better shot at being successful.

u/GoodChanceImStoned · 3 pointsr/microgrowery

If I was really trying to go for the bare-minimum cost setup I'd have it in a closet and here's what I'd do:

  • Random large plastic container with drilled holes on the bottom as a pot (3-7 gallons). I would recommend fabric pots from your local Hydro store which cost around $6.
  • Cheap soil and nutrients (look for Tomato nutrients) that you can buy at Home Depot/Ace Hardware/Your local Hydro store (FoxFarm Ocean Forest is GREAT and you get 12 gallons for $10).
  • PH test strips, for around $5 online (very cost effective, giving your plants the right PH of water will help them a LOT)

    The hardest decision would probably be lighting... I'd advise you either go the CFL route (look it up on growweedeasy.com) or a cheap LED light from Amazon. You can get a 180W draw light from Amazon for $66, and it's decent, not the best, but you can surely go from seedling to harvest with them. MarsHydro is a well-known and relatively reliable brand: https://www.amazon.com/MarsHydro-Spectrum-Certification-Hydroponic-Greenhouse/dp/B00XC3LBI2/ref=sr_1_7?s=lawn-garden&ie=UTF8&qid=1506140832&sr=1-7&keywords=led+grow+light

    The last thing you will really need is ventilation. To start you can just use some small-fan you may have laying around but later the odor will become an issue. You can make your own carbon filter for cheap, or you can buy one. I believe you can get a basic carbon filter/fan combo for around $50 online.

u/PlantyHamchuk · 3 pointsr/indoorgardening

Without seeing pictures of your setup, I'd make a wild guess that they needed a ton more light. As an example, here's a popular light - https://www.amazon.com/MarsHydro-Spectrum-Hydroponic-Indoor-Growing/dp/B00XC3LBI2 - and it is advertised as being for a 2' x 2' growing area (though I think you could get more out of it than that, especially if you made some sort of grow tent equivalent. It's easy to underestimate just how much light plants need.

Growing from seeds will be more difficult and create lots of new hurdles to overcome, if you're still getting comfortable with plants I'd just pick up some seedlings.

However, you mention that you'll be a homeowner, so you might just consider growing your herbs outdoors. Not all of those herbs are perennial (basil is an annual, it will set seed which you can harvest but then it's gonna die), but you could also harvest and dry the herbs so you could have them in the off season if you cannot keep your cats away.

Another or additional option is to grow cat grass and catnip to distract the cats and give them something else to be excited about, and also give them vertical shelves away from your plants to play on or even a catio. Lots of times cats get into indoor plants because they are bored and need more stimulation. Plants and soil are full of interesting smells. Hope this helps.

u/Kyla_420 · 2 pointsr/microgrowery

You also need to get 2 sets of cfls 6500k for veg and 3000k for flowering all those bulbs plus all the sockets and an extra power strip to plug them all into plus hardware to mount all of them cost about the same as a cheap led and you'll be better off going for a cheap led in the end. Like a lot of folks I started with cfls and they are a pain in the ass. You have to change the light distance almost everyday.

u/Mitten_Punch · 2 pointsr/microgrowery

You need more than 36" vertical space. Your fan + filter will take up 10", pots another 10", and you will need to keep the light 12"+ away from the plants. This tent is close in footprint, but with a much more manageable height. Tons of good tents out there though. Just make sure you have at least 5' if you are flowering. 6 or 7 is better.

Can't speak to that particular Mars light. If you only have $150US/100GBP to spend, I'd look into more options. Mars300 for a first grow is an idea. A better idea, if you have the time/inclination, is to build a light. You can get diode strips (Bridgelux EB, Samsum Series H, etc) + 100w driver for the same price, and it'll put out more useful light with less heat. If that sounds like something you want to do, search a bit on this subreddit, and post questions. Lots of builders here.

As for fans, Active Air is a solid brand. Just don't buy anything that look like this--which is a duct fan, not an inline or this--which is an inline that will work for 3 months then break.

u/juanitospeppers · 2 pointsr/HotPeppers

there is not a good kit, you should buy stuff separate.

light, growing space/material, seeds/plants will probably come from different vendors.

if you wanted a super simple, easy to use kit could get an autopot and then some easy to use nutrients, a simple 1 piece light(led or HPS), then some seeds or wait for march and get some starter plants from me =D

More than enough for a Brute build, along with some side lighting strips for the bottom maybe :D.

u/Caponabis · 2 pointsr/Bonsai

yes, LED full spectrum grow lights. something like this dont' give off too much heat and use a fraction of the power. The light is intense. doesn't have to be as close as HPS or Halogen grow light. the light i linked will cover a 4'x4' growing area. get more trees ! (you can also go without a light if it's close to the window and only one tree, it will survive until spring no worries)

u/swimnsmoke20 · 2 pointsr/microgrowery

The light has several different colored LED's. They focus light straight down and out at a certain angle. This type usually appears a solid blue-purple (blurple) when you look in the grow room as the angled light mixes together. The light that shines straight down through small cracks in the canopy gives this effect showing the red blue and white diodes.

I am talking about something like this (random link, not an endorsement) that can be used in a DIY setup. Check /u/LEDWizard 's threads to learn more about DIY leds.

Other than that, even just stringing together enough LED spotlights/directional bulbs would do the trick, just not as good as a COB led array (the ones I linked at the beginning).

Or you could go for a couple (or 3) of these ready made panels. Again, this is an example and not an endorsement.

Either way I'm sure it'll be great, because your setup looks pretty sweet as it is and you generally can't go wrong with LEDs. They last a long time and produce the most PAR (photosyntheticaly active radiation) per Watt consumed that any other artificial lighting source.

u/Carlifex · 2 pointsr/microgrowery

10 of those will definetly do. I started with CFLs until i bought a 250W version and it fucking sucked balls. (was listed a grow CFL). the package shows 14W->65W so that bad boy will produce the equivalent of a 65W subjective "brightness" for human eyes. Definition of Lumen. The specification is kind of misunderstood since it tells you something about the brightness a human eye perseives. A plant has other needs.
nonetheless, with 10 of those you will grow weed, but if you pay more than 7$ a piece you should consider getting one of these for starters: 300W LED for beginners. they got a much better spectrum (not the best, but theyre cheap and easy to use)

u/Morgaine1795 · 2 pointsr/gardening

Thank you for sharing! That is really impressive growth. I hope my plants get that large when I am ready to start them. (Zone 5A currently getting lows at -20F). I have never heard of that type of light, seems to work really well for you and they are on sale so I might have to try one. I wonder if I have one of those but still my other lights if there would be an issue, or if I would just use the mars one.

Also the comments from people on imgur really get on my nerves at times.

u/wheremyseedsat · 1 pointr/microgrowery

It's under one of these: http://amzn.com/B00XC3LBI2

I had it about 12" above, had put it a little closer, but then moved it back up after a day or so (when I started trying to save it). If it's light bleaching, would increasing the distance from the light save it or would it be too late for a seedling this small?

u/Ser_NSFW · 1 pointr/SpaceBuckets

Hey man, happy birthday!

For lighting, check out this MarsHydro 300W LED that's been on sale for the last few months for $89.99 (might be Prime-only?). It is absolutely worth it.

I successfully grew three autoflowers in a 5 gallon bucket and they each had their own peat moss starter pot (you can plant the starter pot directly into soil), but they didn't get too big. I'd start with one autoflower at a time till you're comfortable with the grow process and feel like you want to move up.

I you want to just grow 2-3 plants from the start, consider using two 18-gallon plastic totes stacked rim to rim (like a GNK Power Droid from Star Wars) - you'll have plenty of space, and it's not much different from a 5-gallon build!

u/19cent · 1 pointr/microgrowery

Guess I'm biting another bullet, is this the correct one?

Edit: Also, with more heat now, should I get a 6 inch in line fan ?and if so how will I rig it to my tent because the largest vent is 5 inches ?

u/tesselaterator · 1 pointr/portlandhomegrowers

I have two of these
http://www.amazon.com/gp/product/B00PH1MQV8?psc=1&redirect=true&ref_=oh_aui_search_detailpage
and one of the Mars
http://www.amazon.com/gp/product/B00XC3LBI2?psc=1&redirect=true&ref_=oh_aui_search_detailpage

the first one - galaxy hydro - is much purpler .
All three are in a small area - about 5 feet by 3 feet
I have 3 plants in there and they are doing great.
My total wattage consumed by the fans and lights is under 500w so obviously the advertised wattage is not accurate (3x300"watt" leds producing under 500watts?)
however they are SUPER bright and the leaves are deep dark green.

u/Battered_Unicorn · 1 pointr/microgrowery

Imo you'd be better off getting a cob setup with cbx 3590 or vero 29 cobs this site has some good options to choose from. If you want to try out something different with good coverage and efficiency check out qb boards. If you want something affordable, yet powerful go with a 600/1000 mh/hps light. If you just want a basic cheap led light marshydro 300w(132w actual) is a good start.

u/_Jolly_ · 1 pointr/microgrowery

I would still go with a 300 watt UFO led. They are probably the most efficient because all of it is contained in one unit including a heat fan. It also has a limited scalability if you ever wanted to increase your grow size.

The above LED is full spectrum so you do not need to switch out the light during flower. There are other LEDs in that price range that have dual mode which means you flip a switch when you are in flower and it changes spectrum.

u/HamsterBitch · 1 pointr/microgrowery

I have that light and it is not enough to grow a plant under. Check out /r/spacebuckets for more bucket/small grow info on something the size of a mini fridge. This or This will grow plants in a small space, I've grown under both.

u/VeryLowSodyPop · 1 pointr/succulents

if you buy this light HERE if will keep all of the plants happy, even the wee weedle

u/thedolomite · 1 pointr/microgrowery

To light 16 square feet you should have around 800w of blurple or HID or 500w of COB or QB. I'm not sure you can achieve that with a budget of $150, though I could be wrong.


If you can increase the budget a tiny bit $185 will get you a state of the art light that will cover a 2'x2' area of your tent and you can add more later:


https://growerslights.com/collections/horticulture-lighting-group/products/horticulture-lighting-group-135-watt-quantum-board-led-kit?variant=42276846026


Or you could go with two Mars Hydro 300s, at $75 each, which would give you about 265w, enough to cover a 2.5'x2.5' area.

Using a single Mars Hydro 300W (130-140w something real output).

This is the nutrient solution I am running, with a 3/2/4 N/P/K-split.

Would it be better to use the HESI's hydro bloom nutrients I've already bought that has a 3/4/5 N/P/K split then throughout both vegetative and flowering phase?

u/honkimon · 1 pointr/microgrowery

You got an ounce from a light that's meant for a 2x2 space? That's really good isn't it? I'm currently looking into possibly trying indoor for my first time and that lamp curently goes for less than $70 on Amazon.

u/newFUNKYmode · 1 pointr/microgrowery

Yea I think OP has 2 of these lights , looks like their true wattage is at 132W each

Get a cheap 300W Mars Hydro. You'll spend more using CFL's anyway so might as well bite off on something like this.

u/ExtractionNub · 1 pointr/microgrowery

There's more powerful models as well. I would suggest checking Craigslist as there are always growers getting rid of old equipment.

Hey Guys.

As my first grow ever, I had 3 seedlings germinate after planting on April 5th into my AeroGarden 6. Here is a progress picture from about 3 days ago.

As you can see, my guy on the left is really taking off, but my other two have kind of stalled. Should I be worried about that?

I hear I can wait about another week until transplant. Would then be a good time to move them into 5 gallon pots? I am also laxing behind on my equipment. I’ve been scoping this tent and this light off of Amazon. Would you guys recommend? Any other recommendations for ventilation? Working a bit on a budget.

Also, I checked all 3 of them, and they have mainly just one long root as seen here. Should that be concerning?

Appreciate any info, and sorry for the noob questions. Happy growing!

I guess actual wattage is 132w, according to its listing on Amazon

u/saddvibes · 1 pointr/microgrowery

I found this on amazon and saw basically the whole review section saying it’s great to grow weed with, what do you think? https://www.amazon.com/dp/B00XC3LBI2/ref=cm_sw_r_cp_api_i_6t10CbP5A8DGZ

You could have one nice big light, or a couple of smaller ones. Depends on how long you are going to grow indoors, and your budget.
https://www.amazon.com/dp/B07BFPBBD6 This fixture
https://www.amazon.com/dp/B01MXLSEJ8 with six of these, would result in 4800 lumens.


https://www.amazon.com/dp/B0721TG86M here you have 5000 lumens


https://www.amazon.com/dp/B00XC3LBI2 you could do this one, but the light is terrible to live in.


https://horticulturelightinggroup.com/products/hlg-65 And this would be your best option. 10.000 lumens.

I have the 300w from this brand: https://www.amazon.com/MarsHydro-Spectrum-Hydroponic-Indoor-Growing/dp/B00XC3LBI2


I have definitely added the thermometer to my shopping list, thanks for your input, its greatly appreciated!

u/Numberoneallover · 1 pointr/microgrowery

This is actually a grow light and it's cheaper with a few more watts. It also has some red spectrum.

https://www.amazon.com/dp/B00XC3LBI2/ref=cm_sw_r_cp_awdb_XfIgzbAKYXPV1

Edit: I see you already own it...it could help as supplemental lighting or as a veg light

u/its_my_growaway · 1 pointr/microgrowery

Mars Hydro 300, it's the standard intro LED and very cost effective. Lots of great grows posted here under those lights. Even if you upgrade to higher wattage, the little 120-130W "300W" panel will be excellent for the early stages of your plants.

You can also look into T5 fluorescent, which is what I use for veg but could be used for a small flowering setup. The best part about T5 is its extremely low heat output. You can grow the plants until they're touching the tubes practically. I would skip CFL, I feel it's a poor lighting solution that's a waste of money (up front and cost over life) in the light (heh) of high performing LED panels and inexpensive and more efficient T5 setups.

Mars 300 watt, I have three in a 8x4' tent, they work great.

u/afhlidh · 1 pointr/microgrowery

I was actually looking at that one, but decided that this one may get the job done:

u/FreakOfNature247 · 1 pointr/ReefTank

Any light that is used to grow herbs/tomatoes should work. I have https://www.amazon.com/MarsHydro-Spectrum-Hydroponic-Indoor-Growing/dp/B00XC3LBI2/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1509648710&sr=1-1&keywords=mars+hydro&dpID=51clUyqI-5L&preST=_SY300_QL70_&dpSrc=srch and the only issue I have is that it is too powerfull for the distance I have it from the refugium. Tends to bleach out the chaeto if it stops tumbling.

u/Infusables · 1 pointr/microgrowery

Don't go with the cheaper light. 50w of red and blue led's arent going to be enough PAR to get you through flowering.

The 2nd option should work. but instead Look into mars hydro 300w LEDS. I've seen grow videos on youtube of someone using 1 of those to veg for referencelink and 2 to flower. he produced 6 plants that way.so you may be able to get by doing 1 plant under 1 300w led. The plants yield will be limited by the factor in least supply- so all the light wont help if your short on nutrients, and all the nutrients wont help if your short on light. 300w redbluewhite led is a good start for a casual hobby plant.

u/mrselmedir · 1 pointr/microgrowery

This is what I used for my 2x4 tent and it worked perfectly - https://www.amazon.com/MarsHydro-Spectrum-Hydroponic-Indoor-Growing/dp/B00XC3LBI2

u/Newgrowercan · 1 pointr/microgrowery

The link in the starter list doesn't work. But the Mars 300 are still widely available at cheap prices on Amazon and ebay

u/zachbraffchemistry · 1 pointr/microgrowery

So If I would upgrade I'd probably take something like this Mars 300w. However I read that the true wattage is around 170w while the true wattage of my cfl setup would be around 184w. Is this relevant?

u/Tsii · 1 pointr/gardening

You using this light?

Looks like you have it 12-16" above plants and a what... 3'x3' area for each one? I just built mine, but was considering getting more or getting a setup for when the big plants get bigger than the shelving would allow.

Looks like you have ~13 tomatos under one and ~17 tomatos/peppers under the other... how big will they get until you plant outside? Will those 2 lights be enough? (Just trying to figure out my own logistics)

I like the room though btw :)

u/Ehmpont · 0 pointsr/microgrowery

when I upgrade should I go for a 300w or the 600w?

u/Skingle · 0 pointsr/microgrowery

watts don't apply to LEDs in the same way as cfls or HPS/MH. and these are reflector series which are different than regular LEDS. companies have come out with newer reflector series recently.
for example with mars hydro
they have regular

and new reflector series

wattage is lower but they are more powerful or the same power while using less energy, check the ratings on both. they direct the light more intensely with the reflectors.

i have 2 viparspectra 450 watt reflector series and they work great for my 4x2x5 tent.
and 2 smaller lights are generally easier than one big one. more evenly distribute the light to your girls
