I have one quick question if anyone can answer this.
I am working on setting up a SCROG. Now I was going to use a 400 Watt HPS. But was wondering if a 250watt HPS would produce almost the same effect as the 400 watt.
I am using a cabinet that is 4Wx3Dx5H. with a total of 12 square feet and and a total of 60 cubic feet. The output of the light in question is 26,000 lumens.
I wanted to cut cost a little and still end up with around the same yield or close to it at least.
oh yeah and one more question. if i were to change the color of the lens of a bulb for instance does that change the spectrum at all. say a yellow spectrum bulb covered with a blue colored sheeth? not sure just seen some tubes and was curious.
The 400w is 50% weaker than what you need for an area that size. even with a good reflector you'll get air buds around the periphery.
PC :smokin:
oh so what wattage would you suggest then?
800 watt to 1000 watt? I am guessing.
20-50 watts per square foot, the more the better.
by the way PC love the sig
"Let the old men who make the wars, fight the wars."
agreed...........
Forgot about that rule. Wow my heads gone today. yeah thanks for the reminder. I will calculate and figure out what is exactly needed.Quote:

600 will work....4x4....
** 3x4=12x50=600Quote:
