i only decided on one strong pheno i acquired in a pack, but my pheno is a heavy feeder, definitely likes the clone method of topping. i think uncle ben or someone does something similar to it. as far as an og hybrid goes, it is very strong and can handle it's own weight. you definitely have to look for a good pheno though, so expect not to find a solid one your first run. to be honest, i love my pheno, but i've seen a couple online that makes mine not look so great. and to be honest, this winter outdoor came out kinda small. i will show you what my indoor hgk is looking like and it is definitely much more promising. if you do the clone method of topping or "uncle bens latest topping method" you can get a heavy heavy yield out of her. i love the hgk, it's a good one, you just have to find it.
