500G in a 3x3 600w?

[cork144]

Simple question, with a 600w hps, 36 plant 3.5l pot sog is 500G feasable?

are there anybody who runs this sort of sog? how much veg time would be needed?

Strain and choice of medium will be big factors in how well you can push over a pound in that setup, but it can easily be done if you know what you're doing.

Make sure you have enough space to actually fit all the 3.5L's into the 3 x 3 area, 6" per pot width/length, and that's not considering work room. It's going to get crowded in there fast, so a long veg will not be needed. If you have clones rooted, maybe 1 week veg and then flip, but again it depends on your height restrictions and environmental limits. Trim anything below 1 FT of the canopy the HPS won't penetrate any further and you'll max your yields.

I'm planning on grabbing a tent and doing this same type of setup but with less plant numbers, so if anything seems off to you about my advice don't hesitate to point it out because I want to learn as well. I'm thinking ebb/flow with a res or a coco drip system/scrog setup.

You can probably get a pound but i would use two 400s instead of one 600, the cannabible says that two 400s will more effectively cover that space than a 600 watt would---- / 400 \/ 400 \ versus / 600 \ <-------- if you can kinda visualize that, 36 plants under a 600 is gonna be crowded man, with a 400 you can put 18 under each light and they will get more lumens.

what you are thinking is sorta close to what im doing rith now and im probably only gonna get a 300 grams off two 400 watt trays. my grow is 36 plants total with two weeks veg from clone, they are pretty small (2ft) and i didnt top them so i guess thats why my yeild is low. you can check my thread to get an idea. my plants only have one top cola so the yeild is shitty, you want to have a nice 4-5 cola ring on each plant, and that requires a longer veg time.


if you want a pound off 36 plants, veg them for 2-3 weeks, TOP, veg for another 2-3 weeks, then flower.

i found that un-topped plants with little veg time really produce crappy little 1 cola plants, i guess if you had 50 of them it would be somewhat effective, but thats more pots, more irrigation lines, more soil, etc...

on my next batch we are vegging our plants for 1.5 months with a nice top and trim, my veg plants are already looking very beastly with at least 6-7 top cola sites, i cant wait to flower them because i already know the harvest is gonna be way more than my current grow. the best part is theres less plants. i can get more off these 6 monster plants that i will off my 36 scrog plants.

you might have a better chance if you flip that 600 vertical. That's what I'll be trying next.

 

[Centrum]

2 x 400 50,000 lumens each , one 600 watt 95,000 lumens.
200 more watts for 5,000 lumens ?


I think tony might be right about the vertical being your best bet.

multiple light sources = less shadows, is what I think he's talking about. But two lights has its own added hassles over 1.

I have that same set up (almost). 600w Hortilux bulb, 6" air cooled. 3' x 3' botanicare tray with 30 gal res. The only difference is i have 30 ladies in net cups of hydroton and not 36. The basic principles are the same. trying to yield 1/2 oz per plant is about a p. To do that #1, start with your healthiest clones. take more than needed, no duds go to flowering. and #2, veg 2 weeks from well established clone. by well established i mean that they are starting new vegative growth tips (not root growth) while still in cloning. That prob takes 20 days from the day of cutting.

that should be it. With the any moderate to heavy yielding strain you shouldnt have a problem, barring no pest / mold / disease.

although i talk a big game, i still havent hit the 1g/watt mark yet. i attribute that never running the same strain more that once in a row and growing mostly cali 'elite' strains (<--- i'm not being a snob, that the only was i know to get my message across) which often yield significantly less.

Grow something like Chronic, a Double Dutch or Pot of Gold and you should crush this. 600 watts are the most efficient bulbs.

Thanks everyone, My friend wanted to know what he could exspect from the area.

allthough 2 400s does sound good, he wants to run 2 600w bulbs with a flipflop running 2 flower chambers 12/12.

Seems apparant though he is going to also need a veg chamber, he wanted to originally put rooted clones into coco and just flip to 12/12 from there.

2 weeks veg under a 400mh then into the 600w flower cab sound alright?

 

[fjällhöga]

exactly what centrum said ...

and yes this one is do-able with the right clone and skillz for sure ... , veg time would be 2-5 weeks depending on the clones stretch ...

 

[157]

man and i thought that i had too many under my 400 with 9 so i reall could have put 14 under 1 400

 

[Yes4Prop215]

^they would be smaller ones though. i ran 4 large plants under a 400 and it yeiled the same amount as 10 smaller plants under that same 400.


centrum, is that really true about the 200 watts for small gain in lumens? if thats the case i should just throw away my 400s because i can probably grow all my plants that are under the 400s under a new 600.

"Seems apparant though he is going to also need a veg chamber, he wanted to originally put rooted clones into coco and just flip to 12/12 from there."

yea thats what i wanted to do to, but unless you have trays of 50, and like 4 trays or 50, you wont be getting any kind of good yeild off a bunch of tiny ass little plants. i really reccomend at least a 2-4 week veg, with a nice top and trim.

Or you could run two separate boxes, offset perfectly so when one shuts off, the other turns on. Looks to the power company like a continuous load rather than 12 hour spikes. Plus it's a continuous load for the whole day of only the total wattage of one cab. 2 600s would be ideal though IMO. 600 is much more efficient for some reason. If you already have the right kind of 400W HPS ballasts, you could always get a Philips CMH for it.

 

[whodair]

some people grow fewer, yet larger plants, due to legal considerations. single cola plants may be ideal for your run

thats what i mean by ones on for 12 hours then the other switches on..

veg cab will now probably be a 250 over the clones in 9cm pots for 2 - 3 weeks in coco, transplant to 15cm square pots and flip to flower, since its coco the plants shouldnt have any real prob being in a small medium ammount.

Mates aim is to run under 1k 24hrs a day, so with a 250 veg cab 150watts is for fans ect lol... hes prob gonna end up going a lil over.

one tray of vegged clones will go in every 32 days, so hell be harvesting a 3x3 every month basicly.

600 watts are the most efficient in lumens per watt sounds like a fair statement. however, if the 600 throws off the temps in your environment, it is no longer so efficient.

agreed. but you have to set up proper ventilation anyway. If you run your lights in a 6" air cooled hoods with the proper fans removing the air from the growroom, you should be fine. I agree that if your conditions and envirnment are off the 1g/w cant be reached with any method besides luck.

 

[Yes4Prop215]

this is making me consider buying some 600s if that lumens/watt ratio is true.....im running 2 400s right now (800total) and maybe a 600 could cover all these plants...

I don't know, but I'm sure 2-400s and 1-600 would do it.

It's so hard to stop buying lights.

 

[swampy_nz]

It can be done.
my last run i got just over a pound from a 2x4 closet with 3 plants under 600 watts.no need to run that many plants.

Very much true.
600 watt bulbs are extremely efficient.
