Tell me if my set-up sounds ok.

[Frozenguy]

I'm going to grow with (1) 600watt aircooled light.. I'm trying to decide on sqft. like, i'm thinking of like 7-9sqft.. and i'm gonna do 20 plants in 1gal pots.. I think they are 1 gal, they are 6.75"Diameter/ 6.75"tall.

so 20 plants under 1 600watt light? it will be put pretty close down

clones will veg in beer cups then transplanted into those bigger pots for about a week or so before flower.. maybe about 5 days.. what do you guys think? that only gives about 30 watts per plant!! is that enough??

 

[jojajico]

can i ask you what are your yeild goals? u may get better productivity if you have even mor elight per square foot. im doing 100 in my current grow. with CO2, only 16 plants under a 600 watts. and im hoping for 1+ ounce per plant.. very doable with CO2 maybe even 2 with the right strain and everything dialed in.

 

[aeric]

You want 50-60 watts per square foot, which comes to 12-10 sq.ft., 3x4 would be good imo. I don't know what you mean by those other figures you were using...

You might want to veg longer in the larger 1 gallon pots, not only for veg growth, but to get lots n lots of roots down below. More roots = more fruits. A rooting supplement like Rhizotonic...or whatever would help speed that up. No matter the medium, it would be good if you can get enough roots where the plant needs water (under right temps and humidity) every few days, this has many benefits. If you already know this stuff sorry for being redundant.

 

[sensirocker]

hmmm... what strain are you using? i hope its something that doesnt stretch much... still tho, sounds very exciting...
i personally think that ones better off going with 8 well trained plants that have been vegged for 4 weeks with LST.... but if you dont have the time or patience then theres not much of a choice then huh...
i just dont thikn your gonan get really consistent, fat nugs across the yield if your gonna do that many plants... i would agree with joja and cut it down a bit to 16 then you can have a nice and even 4'x4' square that should work well with the 600w footprint.

your right 50 - 60 wpsf is good but ive heard the benefit goes all the way up to 120 epsf. after that there are diminishing returns.

Didn't you just come off of your first grow with CFLs? Already expecting 1-2lbs from a 600w on the second?

 

[jojajico]

first grow indoors yes. is it too much to expect 1 ounce per plant with a full nutrient line and CO2?

 

[TGT]

I don't think so. I think 1 pound per 600 is quite possible for an Intermediate grower. I say if you know your stuff you should do just fine. Just my opinion of course, I could be wrong.

joja: you may be correct but my understanding is that diminishing returns happen at 80-90 wpsf. Being that he is a little new to that kind of setup I would err on the safe side, because that kind of intensity brings it's own problems. I don't think it's too much at all for you to expect 1 ou. per, if you have the right density and say, 16 plants, the Co2 certainly helps that, but it could easily be more or less depending on....everything.

Try getting the adjustawings from high five grow shop.

If your gonna go with one light then this will def. spread that light out while creating a shield for the hot spot. So you can put your plants very close.

Its really good. check it out way better than an air cooled hps.

Just my 2 cents

Peace

 

[JJScorpio]

A 4 by 3 ft area will give you 50 WPS. You will have more than enough room for 20. You might be better doing 10 in 3 gallon pots. It will be interesting to see what the 1 gallon pots do though......

 

[Frozenguy]

yeah, i'm basically going larger plant numbers with lower veg time and wanted to konw how many plants per 600watt light you guys would recomend. I'm going for anywhere from 70-100 watts per sqft. my last grows have always been close to 100w/sqft.

was i was mentioning was that if i have 20 plants under (1) 600watt light, that will be 30 watts for each plant.. right? reguardless of growing space, vegged appropriatly, each plant will be recieving about 30watts.. is that enough?
i'm wondering maybe 16 would sound good too.. i just figure its easier to hit a high yield goal with more plants yielding less.. (then vegging fewer plants for a longer period of time)

 

[jojajico]

u guys may be right. but ive seen a 100wpsf grow under a 1000 watt prodice nearly 2 lbs without CO2. ur right, ill have to get everythign dialed in to do this, but i got over an ounce from flourocent lights without CO2 without nutrients (besides a little something in flower) and growing in some mircale grow soil. lol. so a pound... if a i plan it out shouldnt be a problem. plus i got the help of you good folks on IC. a little less than i gram per watt with CO2 and a full nutrient line should not be a problem. 2 grams per watt is the eventual goal. tuff but doable.

dont worry about watts per plant just watts per square foot. if they are over 50 you will do just fine.

yea right on. the 120 is something i heard cant confirm it but i have seen 100wpsf grows that showed a definate increase in yeild. im planning down the lone to build a dual 400 watt grow one hps bulb one mh in the same area (6 square feet) that would put me just over the 120 wpsf "limit" it will just be an experiment to see if their is any valididty to the claim. i think th emost important thing is to keep it cool if you can keep all that light cool you should be ok.

1st grow indoors...600wHPS...CO2 enrichment...1gal pots...

First, some pics of your grow area would help out. If you do all the right things 1lb off of a 600 would be an excellent yield. Judging by the advice you are getting you should have some good ideas to go off of. Go with soil...give them a long veg and you will do fine. But just don't be let down if you don't reach those yield marks...as every grower knows, there is more to eventual yield than a diagram and a trip to te hydro store.

Best of Luck

[jojajico]

if he does his research there is no reason he cant pull it off.

 

[Frozenguy]

yeah.. this isn't my first time growing.. this is my smallest grow yet. I'm just not used to growing with 1 light.. i never have.. i was just looking for some provan plant to light ratios for a 600 watt light and someone using 1gal pots.. i'm thinking anywhere from 16-25.. probably more like 16 or 20.. i want minimal veg.. i'm going for SOG. possibly a perpetual SOG but i'm not worried about that.. this is just a simple grow of mine for some personal medecine..

u guys may be right. but ive seen a 100wpsf grow under a 1000 watt prodice nearly 2 lbs without CO2. ur right, ill have to get everythign dialed in to do this, but i got over an ounce from flourocent lights without CO2 without nutrients (besides a little something in flower) and growing in some mircale grow soil. lol. so a pound... if a i plan it out shouldnt be a problem. plus i got the help of you good folks on IC. a little less than i gram per watt with CO2 and a full nutrient line should not be a problem. 2 grams per watt is the eventual goal. tuff but doable.

a LB is definately possible off of a 600w, but i wouldn't get your hopes up. It takes awhile to get your skill up, and everything dialed in...especially when switching to hps from CFL's.

1 pound from a 600w would be about .76 grams per watt, which i don't think is going to happen on your second grow especially since you haven't used an HPS before. I have had over 4 grows with my hps lights and still only achieve about .65-.7 grams per watt, .5 seems to be about average. Anything over about .8 grams per watt is hard to achieve, especially in soil although i have seen it happen. 1.0 is about the highest you will see in soil, and thats with perfect conditions and everything dialed in.

Heres some tips on achieving your goal though:

Pick a heavy yielding strain if your goal is yield. This is one of the biggest factors as far as yield. I'd pick something that is atleast good quality smoke also, pot of gold or something similar would fit the bill.

Try your best to keep the plants happy, and the grow as perfect as possible. Feed when needed, but not too much. Set the light as close as possible without burning them. Make sure you have proper ventilation. Make sure the ph and nutrient levels are good. Make sure temperature and humidity are good, humidity is your friend in veg but not in flower. Make sure you don't stress them with light leaks, etc.

Try and find which growing style works best for you as far as yield. Under a 600w, a sog would be a good choice.

i got over an ounce per plant with flouros. so im not to worried about doing it with a HPS and CO2. not saying it will happen but i think i can do it, lol we will see.
