5 gallon yield vs. 3 gallon

Jcannabud · May 31, 2015

I have a 2x2.5 space. Will either planting two 5 gallon or four 3 gallon pots affect yield? Would the only difference be a shorter veg period by using 3 gallon pots?

3 gallon = profit???
Or no?

Also, how many watts should I use for my 2x2.5 space if I'll be using four 3 gals? I'm gonna use HID

try it let us no how u go it all comes down to the grower some guys here could yeild more in a solo cup the a 5 gallon rez cause they no how to grow and what to use when so it all comes down to the grower just like saying when is the world gunna end

You really don't have much space. Maybe 1 plant in a 5 gallon in there. You'd have a tree in a few months.

4 in 2 gallon pots under 400w HPS sounds about right. Actually, since seeds cost so much why not just scrog the space with 1 heavy yielder in a 5 gallon.

As for yield, it will come down to your experience level, strain and light coverage. You could get away with a 250w hps, but 400 would be great.

How much height do you have? Where are you venting the heat to?

6ft high
I'll only be using a 4" exhaust fan
I'll be using scrog training as well

If anyone here has experience, let me know how it'd work

Depends man, I have grown monsters in 1 gallon pots all the way up to 7 gallons indoor. I would say it depends more on how long you are going to have your plants vegetating, the longer you have to veg the bigger the pot and less plants. If you want to rush things along you could probably save 2 weeks by going 4 in 2 gal pots. Under a 400w as long as the humidity and temps are in check you shouldn't have a problem. Might have to water every other day or every two days but there is not much wrong with giving your girls some love.

I have a 2x2.5 and run (4) 3 gallon air-pots, it get a little tight. Just upgraded from an uncooled 250w hid to an uncooled 315w cmh and it does get a bit warm. I do use a 8" exhaust. This is my third run an first for the summer. I just switched to lighting at night to take advantage of cooler temps. If I were you I would try a a 250w before going any bigger.

One of the contestants of the solo cup comp #7 got 46(IIRC) grams out of a 16oz cup.

you could easily fit 4 3 gallon buckets in your space.

Four 3 gallon trump two 5 gallon as you will get more colas with less veg time and thereby attain higher yield. I have used a 400w HPS in a 2x2.5 tent and it was fine.

Edit: Due to the height limitations of these smaller tents, you won't veg long, maybe not at all depending on the size of the initial plant. Also, get a 250/400w dual wattage ballast so you can dial-down if heat gets too bad. I had a small fan blowing the hot air out the top of the tent. Ambient was 68F, it was in the winter. Ballast was placed outside the tent.

1 gallon per foot. think roots the more dirt the more room for em and less less room for roots making it root bound

if mh veg id use 400 - 1000w mh and1000w or more flowering. any thing under 600 will not produce full buds thay will be pop corn buds. and id love to see a 5lb yield from a solo cup. but yes its all pref grower to grower on the ins and outs. research with an open mind look at pictures from the ppl giving info and the one that puts out bushes not lil sad Charlie brown tree

You can look at pics of my first veg there are a few pics where i was in a 2 by 2 using 3 gallon pots and I was happy with the veg, of course I rookied that shit using cfl bulbs but I would have to say. If you have the right strain. It will dominate in any setting with the right lighting an the right medium. My avatar was one of the girls from the 2by2 and it was a mutant shrub it stayed tight till it's end.

I agree I learned everything I know on here pics say. It all. Don't listen to the guy with the yellow brown stringy plants that always have issues. Just be patient, look around, interact and you'll be fine.

I run a 2x2.5x7 tent. I easily grow two big 5 gallon soil plants. I run 1000 watts of LED. I could also comfortably grow 3 plants in 3 gallon containers, and still have room for my circulatuon fans and inline fan/filter combo.

noodleman · Jun 12, 2015

Smokenpassout -

I'm running 3 plants (one 5 gallon and two kitty litter containers about 3.5-4.0 gallons) in a 4x2x7 tent with 3 LEDs totaling about 1000 actual watts so your post interested me. Are your LEDs drawing 1,000 watts, as many LED lamps only draw about 50% of the listed wattage? How far are your LEDs from the canopy and does 7 feet of height provide enough grow height for the size plants expected out of the big pots your using?

I hope I'm not hijacking the thread but I couldn't resist posting because of the similarities of your set up to mine.

the size of the roots directly effect the yeild of the plant .............a 5 gallon will be profit much more then a 3 gallon
1 a 5 gallon has more room for the roots to spread out
2 a 5 gallon holds almost 2 times the water a 3 gallon does
3 the stalk u get on a 5 gallon much larger then a 3 gallon so it is drawl more food and water to make flowers

oh the light a 400w will do u nice a 600w would be overkill (if u do a 600w make sure u keep it a extra few inches higher ) it has a higher lumen output then a 400w to much and u can bleach the plants pigment stunting what it can do for u

i run threes all the time 6 under 1-1000watt normally they are about 2ft tall max... i do early quick flips i generally always hit 15-18oz depending on strains under the light which averages 2.5-3 oz per plant. i personally prefer the smaller grows they dry faster and allow the roots to spread a bit faster. and if your not running a long veg a 5 gallon is pointless your not utilizing the whole "media space"

actually i should correct that i run 2 gallon pails.. they hold the same media amount as a 3 gallon smart pot though so i always consider them 3's ... but i guess technically they are 2 gallon pails.

a 1000w in a 2x2.5 space ........i am nutz i freely admit that but that is just sheer crazy man

1000w is made for a 6x6 great for a 5x5 or even a 4x4 ........ but anything smaller then that it is a waste of light (150 k lumens in a 2x2.5 space ) it is going to be more trouble then worth with the IR heat it puts off and the fact he will need to keep ontop or the height of the light .............anything over 100k lumens i know personal exp can and will bleach the plants

oh shit.. no i was just saying what i run not that he should put that in the space... sorry
