Humm, Oshio.
I remember seeing them and I thought the price was kinda high and moved on.
That UV spectrum is something I had thought of when choosing the phillips.
I dont see myself moving to a 600w any time soon.
But it will still be good to hear what you guys think of them.
I got a different idea, Still using 600w but with two lights.
My next move is to use more of my available light by using more of the space I have.
2 tier vertical grow. 400w on top and 250w on bottom. Heres what I come up with.
I will have to remove the whisper fan and mount it on top but that will give me enough space. I figure I can plumb it right into the lower tub. Hang the light right in front against the closed doors. That will give me 2 feet all around. As the upper plants grow towards the light I have the screen to tie them back. The 250w will provide light to the lower buds.
Think it will do as well as a 600w?
