How many plants...

[seventhchild]

sea of green with 36 clones , 4 verities , 4 to 10 inches tall at start of flowering, yield = 9 to 16 oz's in a 3x3 with a 400 w HPS. note that this requires a separate mother/veg/clone area. i grow a perpetual sog, harvest a few every week, move a few in. the sativa dom are flowered shorter [as soon as they show roots], yield less , and take longer to ripen. the indica's are veged a few days after rooting to get them to a good flowering hight

seventhchild Reviewed by seventhchild on 09-05-2010. How many plants... It may have been asked and I just cant find the answer, but how many plants can one finish under a 400w HPS. The grow space would be 3x3.5 ft. And could I use SOG in this small space? What about height, when should they be forced to flower? Im losing my mind here... :i feel stupid: Rating: 5

I'd say every answer here is correct already, but in theory, you can grow as many plants as you can fit containers in that space.

Many factors though... since you are growing from seed you will need bigger pots versus growing from clones. And with a 400w you can't let them get too tall, so topping/FIM/LST/SCROG are things to look into (Scrog only if you have feminized seeds).

Having a separate veg/clone/mother chamber would obviously be a huge plus (doesn't need to be huge, check out the bonsai moms link below). You could veg out one of each strain, do some training (LST) so you'll have a lot of clones (Bonsai Mums: A Guide - Grasscity.com Forums), and put the rooted clones into 3 gal containers filling out the space. Veg for a week then flip. See how they grow and make adjustments from there. Some kind of screen or netting will help keep an even canopy. If it gets too crowded you won't feel bad taking out a couple runts, versus taking out a 3 footer or dealing with shading and mold issues.

^^That's something I was planning to try (if I ever got over having such a high plant count).

a 400w HPS will only form tight bud on the upper 12/16 inches so having your plants finish flowering taller than this is wasteful and is what a SOG is all about. a SOG needs clones... usually LOTS of em....in a 3x3 area some growers put 100+ clones,i put 36 , others may grow 9 or less,but in the end only YOU can decide how many is best for yourself.

I like the idea of 100+! :hippy:

you right mo better than i BIGTOP mo cler info but a three gal pot for a clone thats only veged for one week seems to large imho. my pots are 5.5x5.5x6deep i havn't mesured thier capisity but i'd guess 3/5 to 3/4 of a gal.at harvest 8 to 10 weeks later they are NOT root bound but are filled with healthy roots.wouldn't using a 3 gal pot be wastful of soil and space??

Could be That's just theory pulled out of my ass, I think you have more knowledge than me through your experience with this setup. I have a tendency to err on the side of caution, and I'd rather have the problem of my pots being too big than too small.

Are you using soil or coco? Because (in theory again ), you can get away with smaller pots using coco...

Oh and one more thing for Weedologist, square pots will fill in a space better than round ones :jointsmile:

I use 40% peat moss. 10% vermiculite ,50% perlite these days feed with JACK'S.Ditto your advice on the square pots...for more soil volume go taller not wider.in a SOG you don't want your pot wider than the plants max leaf spread during flowering.

my first grow...(2005) I germinated 18 seeds and had 13 females and one 400 watt HPS light...in a closet.

I thought...I can't throw anybody out?...:wtf:...what can I do?...well, I did have a separate darkroom....so....I just rotated 6 in and 7 out...every 12 hours, and 7 in and 6 out...12 hours, later...:thumbsup:

I did this for 60+ days. I was committed. End result...enough personal smoke for almost 2 years....
which was the orginal plan...anyways...:rastabanna:

I did something like this for about a month on my last grow, wanted to veg longer on one of my plants. Works great, but puts a hamper on your social life and sleeping in on the weekends
