50-75 watts/sq foot is a good ball park figure.i guess what i was trying to say is whats a quick wayto determine wattage to plants
yep thats what I've read..50-75 watts/sq foot is a good ball park figure.
um guys....it depends on what kind of light he's using. 50 watt of cfl a foot wont cut it imo.....10,000 lumens per sq ft is what i shoot for. a 42 watt cfl puts out about 2800 lumens
