alright ill be sure to ditch the foil then even though it was a pain in the ass to put in lol.i have a exhaust fan that flows 50cfm and am thinking about getting another one so i have one for intake/blowing across the plants and one for exhaust,let me know if this is a good idea.another question i got some 6500k cfl's now and they are 60w/900 lumens a peice.i have the ability to run 8 lights but right now only have 1 row of 4 lights going.when should i kick the other row on? as of now the seeds have just germinated and i just dropped them in the cups.i started with 8 figuring all odds are against me.i figure i may get 3 females if i am lucky that is.
