NFT question

I am going to use 5' length gutters and SOG method. so all plants will be small with one bud. How many plants per gutter should do?

Depends of what kinda of light your using.... the amount of light determines how many plants you can grow.....

I already have two 1000 watt hps. . . . .

I would say you can go with atleast 15 plants, prolly more since your SOG them under 2 1000 watters.....

holy shit! I am going to be stoned to the bone forever!!!! mwahahaha!!!! I was thinking like 8, good thing I asked! I will be Growing them in rock wool if that makes any difference. So pretty much with that amount of light I should try to fit as many as possible in each gutter? I am also going to try adding some c02.

Yea with two 1000 watt lights you should be able to SOG a good number of plants, I personally grow 8 plants under my single 1000 watt HID and they are just good old 5 gallon bucket soil grows.

I wouldn't go as far as stuffing as may as you can in each, cause they do need room to grow, both foliage and roots.... so keep that in mind.
