Hps

will a 150w HPS have much of an effect on 2-3 plants? or i woud need to have extra lighting added?

The more the better but 150w hps could do 2 plants just fine in my opinion just try to keep them relatively short. I would top for sure. Might add some cfl's around the sides to supplement anyhow.

yea because i really want hps.. but i cant afford to spend 150dollars on a 400w. when 150 is like 60 usd
so yea was probably gonna try 150.
money is just extremely tight an di still need to spend like $45 in nutes and then fan and materials to build grow cabinent
