bulbs are a little to close to the plants if they are doing that. I just like tubes because the plant can touch the tube and it will never burn and they grow very nice. A 400w hps should be fine for your flowering because you prob won't end up with 7 girls.[/quote
Im going to put the plants under the HPS when they get to about 6", because theres not enough room on the top shelf. Is this a problem?
