It may take a grow or two to get it worked out but yes absolutely. I have plenty of hps experience and I say 1/2 cob wattage is all that's needed to beat out hps. Plus the spectrum is much much better. No bulb changes, no need to swap out metal halide bulbs. I'd even take 200 watts over 600 hps watts just for the quality difference. Yield at that point would probably be less though.So you think this 300w setup of COB will be able to replace my 600hps? Of Mach it at least.
