Since I had some miss communication with my clone supplier I ended up with PK instead of Nebulas (no big deal) but I don't know if I'm gonna have enough space for all of the 18 plants I have now. I've read PK can get bushy but still be kept at 2-3 feet tall. I'd like to keep them at 2 feet or lower so that I can use up all 18 plants. Right now they are about 4-5" tall. When would I flip them to keep them at 2 feet max? I could use Dr Nodes to make sure they don't get past 2 feet tall but not sure if DR Nodes will make them even bushier.
