in that space. I would top'em. I don't generally recommend this, but in your case I would top, and flower in 2 weeks. Peace

Don't worry about all the stuff you don't have. get a finished grow in...with what you do have.
FYI MH for Veg, HPS for flower Or;
cfl for veg and any HID for flower.
I ahve flowered with both MYH and HPS, and I actuall vegged and started flowering under MH which seemed to elongate the buds...after 4 weeks I switched to the hortilux, and I never had seen before the giant Kolas I was able to produce on those plants. anyway...rambling. Peace
