I have a question I'm using two lights both cfl. One is 18w =75w and one 13w= 60w is that good enough for 1 plant.
Also, don't worry about what the lights are equivalent too. The box might have a big 100W on it, but is actually only 13 watts. Look for the lower number.
What i'm saying is, the equivalent means nothing, it has nothing to do with how hot the light gets. Ignore it, it will just confuse you.
