Yes i will be using those fixtures but yes will be changing the bulbs, i only used those things cause i had access to free ones and i can get more for free, i just have to buy the bulbs, i would love to run an hps but with the limited space and exhaust issues i opted for the fluorescents.I am just trying to keep it real small and simple for now.As for pinching, no i never have done that, i was wondering if you knew a link to read up on pinching with possibly pictures describing it ???? Another thing, is i have a family member coming by for the day from far away and didn't want them to see my babies,i was just gonna put them carefully into large totes for their dark period as to hide them from my family member, should i leave the lid open a bit or put holes in it so the plant can breathe(it will be in there for it's 6 hour dark period) Thanx again !!
