I switched back over to cfls. The 2 Meizhi 450 don't have enought blue to grow autos.My pineapple express never changed in 4 days and 12 hours under the cfls and they doubled in size and also during my last grow I staggered my 6500k and 2700k bulbs and the plants always lean twards the 6500k bulbs.
This week I feed the pineapple express 2 mls micro and 1 ml bloom.
