Hey hey

I planted some clones on the roof for my mom a couple of weeks ago... there are 2 that are doing quite well, still vegging at about 11", but i got a bubba kush clone that is starting to flower at about 8-9". I realize there is little i can do to make them re-veg, i dont have an indoor light to put them under, do you guys have any advice as to how I can slow down the flowering process? if pictures are needed i can try and upload some on here

thanks for your help
