Hey sorry noob here currently using a 125w draw LED and want to upgrade but limited on cost and want a plug and play. Out of 2 citizen cobs running at 60w each at 3500k vs this PopularGrow COB 800W Full Spectrum LED Grow Light Indoor Plant Hydroponic System | eBay What would yield more?
Well it's hard to make up for 3x the wattage but you could always expand the cob setup as time goes by. If I were only running 2 cobs I would drive them harder than 60w each probably 100w each ish.
