So I made this grow box from a old speaker box. I added osculating fan air flow. I plan to add a exhaust fan soon. The lighting is 3 cfl's. All 25 watts. I've attempted to grow numerous times but everytime the plants die after about two weeks into vegatation and they only grow till the tips of the leaves are bloomed. After that they die. If anyone has any help on this, if it deals with lighting promblems please write back.
