cheers mate,i think you have put my mind to rest.this is my 1st grow and have only small area 2'6x 3' x5'6. istarted with 4 but sent 3 away as my area was too small.i have been using cfls in compost and used cheap nutrients,will post results(don't know when to harvest).this is not for smoking it's for oil extraction.not even sure what strain they are I bought 100 seeds for £1 each.
