Will 50/50 65 x2 grow plants in a 55? Just picked up a 65x2 light that has 50/50's in it. For a good price but will the 50/50 do it for a 55gl.? I have fast growers now on a 29 hex 70watts. Thanks Richard Any one want to trade for some 50/50? just ask.
Actinic lights don't do much for photosynthesis. That leaves you with 65 watts left. Thats 1.18 WPG. Honestly, with a good reflector you need 1.5 WPG or better. 2 WPG with CO2. But, maybe I'm wrong. Let us know if you can grow anything with these.
