Hey GC! Starting the new year with a new hobby and need some veteran advice for the my setup. I've been lurking this great site for over a month now; however, I still have a few questions about veg growth and flowering in the same 3x3x6 cab. SETUP: (nothing purchased yet) Cabinet: 3'w x 3'l x 6'h 600w digital ballast Air cooled 6" hood w/ reflector 6" inline fan for hood MH for Scrog veg HPS for flower 8" inline fan for filter. 10 gal pot w/ recipe I found on here. (Thanks Not Sure) Theory: I would like to grow a two plant scrog in this area. I plan to veg with the MH until my screen is 70% full, then switch to Hps to finish filling in the screen and for flowering. My question is, will switching bulbs like that harm the plant? Any advice or criticism is welcomed!
