how much can you expect from a single plant?

I have 3 plants, one is much larger than the rest, can someone give me some idea of what to expect please? maybe some examples?..

you cant have a real estimate of yeils only a guess what lights have you got nutes strains,medium,,need pics and lists

i have a 400w HID with a 4 inch inline fan blowing ac air, keeping it a constant 74-76 degrees, also its in a DWC with 4, 4inch airstones being pumped with 590 gpm air pump. Cornucopia X2 and Bloom nutes, and its diesel


this pic was before i moved it into a better space with lamp 3 ft above the plants, also this pic was taken before put into bloom, which is in about 4 days currently

ive seen a plant produce as little as nothing, and as much as an LB...hope this helps

your putting it on 12/12 in 4 days have u enought space it looks stretched its gunna get bigger in flower..and ill guess at 1.5-2 oz at rough guess

reread..this pic was before i moved it into a 4x4x8 space, giving it 3 more feet high and more width for growth

in soil the most common amount would seem between 2 and 3 oz per plant. in hydro it should be more but like the guys have said it almost impossible to guess, as time passes and you gain experience you'll be better able to make informed guesses.

it was too hot, had to build it a new, comfortable place

ok mate no worries good look keep the updates coming..

About 2-3 oz. You should put the ac duct down low and exhaust high. Another thing, are they weeds/alfalfa growing out of medium under plant???

weeds/alfalfa growing out??..
