the only people that are doing these kind of numbers consistently and with tested proof, afaik are the isrealis, cbd crew are probably the next closest thing but playing catch up.
its not for sale as its unavailble without medical prescription but this is the closest ive seen
hi greenheart, your plant looks very good, dont remove any leaves, just leave it for more buds.
Now the weather should start getting warmer, try putting the cuttings in a 15 or 20 litre pot i think they will do well and get even bigger than their mother.
looking great, theres not much point leaving this strain longer, it matures quite early and once the hairs turn brown it wont do very much else after that, it will give the effect you're after without the ambers dont worry, ;)
