my plants are 3 weeks into flowering and there looking pretty good and iive used cfls the whole way through, just make sure you have enough. The more light the bigger the yield.
I was wondering if firbreglass/loft insulation was ok to use as a growing medium? I was told it was poisonous to the plants.
I know fibreglass and rockwool are sort of the same texture.
How many plants would you recommend putting in a 4ft long, 4ft high and 4ft wide grow box with 7 CFL's 5 18w and 2 11w. The picture isnt very good. The growbox will be twice the lengh of this one.
