alright, if youve got your plant to flower, couldnt you just cut off individual buds, dry them and smoke them, and still have the plant to grow?
yes you can re-veg a plant. I've been told to cut off all except some bottom growth and put it under 24/0 light and wait
that wouldnt be very smart, it will decrease yield a lot... un less u mean re-vegging, then yes that is possible with 24/0 lighting
