Gorilla Glue Auto -Herbies

I don't know about the Purple Chill but I myself am growing both a Gorilla Glue and an OGKush in the same tent and can tell you they're very different plants in terms of height and structure.... They're both almost 6 weeks old now and the OGKush is a monster I've had to keep in check while Gorilla Glue is a little tamer, a little more "ladylike"... (it's my "Next UP" diary). What I would do is start LSTing them now - get the taller ones down to somewhere close to where the Gorilla Glue is in terms of canopy and consider Scrogging all of them when they start into flower.. That's going to be your best bet for keeping them all in sufficient light and not have OG and Purple crowding out the light on GG... Nodes on indica dominate strains are fairly close together - certainly much closer together than on sativa strains ... raising the lights would encourage more stretch but that is their natural growth pattern ... I would still hold those two monsters-in-waiting to let GG keep up with them... Good luck!
