I have a small cab of about 2.5 by 1.5 by3 ft and I need to know what is enough light for this small cab, I don't wan't to have too much light. And if i have Fluorescent lights what combination should they be (cool, warm) light.
IMO There certainly is such thing as too much light. The sun gives about 50 000 lumens per square meter on a clear summer day. The idea of an indoor grow is replicate as closely as possible the conditions your plants would be in outside on a clear summer day, which is the best condition for growing. To use more light than that can even harm your plants, can make the temperature very hard to control in mids 70s 'green range'.FireWeed said:Theres no such thing as too much light you want to get as many lumens as you can on your plants.
