The day they make a 60 watt board that can replace a 400 watt HPS, I'll buy 20 of them! And sure you can use it as a supplement to the HPS
Yoo just won the invisiblesunled comp!! Bagged myself a 60w QB.... can i use with 400w hps??? Guessing its not strong enough for 3/4 plants in at 80x80x160cm tent by itself?
