I'm sorry, I'm having a little trouble understanding. So you alternate your plants between your veg and flower room? I'm assuming you keep your lights at the right spectrum for flowering.. It sounds like a really good idea, and I don't mind working a little extra for them, could you please explain?
is this your first grow? not including a plant in your windowsill perpetual growing is fun but its ALOT of work especially if you don't have a lot of experience growing
i did similar to what chuck does with a few differences ...
what he means is when you first put your girls into flower your basicly just killing time not a whole lot goes on while waiting for them to sex maybe a week or two of wasted light
during week 2-4 they will really shoot up and almost double or even triple in size so what you do then is move them under a larger light (the higher light) during week 4-6 bud production will start to kick in and slowly but surely your buds will get fatter and fatter in week 6-8 depending on the strain i prefer indica so typically its 6-8 or 9 weeks, in sativa it could take 14 weeks or more anyways back to what i was saying around week 6-8 or maybe 8-12(for sativa) *biggest light* things will almost seem to stand still to the naked eye this imo is the key moment in growing all of your efforts lead up to these few days buds will fatten up significantly trics will start to turn and will finish you can slow cook a ham all day but in the end it doesn't mean dick if put that honey glaze on and don't give it ten more mins so the sugar can caramelize
in my room i only had 2 lights
veg
week 1-2 t5s
week 2-4 1000w mh
flower
week 1-2 2x250w cfls
week 2-4 400w hps
week 6- 1000w hps i had some sativas too but i had a umbrella reflector on that 1000w so i could fit alot in my room
my only advice would be, don't bite off more then you can chew take it one step at a time good luck and stay high
