Sure you can flower in the flower room,,, but if you have the space,, let it go in your veg tent, least the first couple weeks.. From what I think,, and I have little knowledge of autos seeing I've only grew 10-15 of them over the years,, but I'd imagine she's go faster and bigger buddage under 16/8 or even more daylight,, up to 20/4. To me 12/12 wood waste afew extra hours that a auto can use to produce sugars.. Plants could flower under 24 hours light too,, but plants need a dark cycle to grow,, least all I've learned is plants grow mainly at night .. That veg cycle lighting will also help keep her shorter, the yellow hps, or flowering red LED lights lend to stretch.. If I want to keep my girls shorter in flower,, I use my veg MH lamp for the first 10 days of the 12/12 cycle.. Seems to keep plants tighter and shorter.. Just my 2 cent,, Keepem Green
