Im about to attempt a SOG pushing 100 clones. I have a connection to several mothers, but they won't be ready until probably Jan 1. I'll cut the clones and put them in my own cloner. It typically takes 2 weeks (10days ~) for the clones to have a nice root ball, I'll probably let them go another week just so they will be steady strong and hopefully vegged ready for flower. I using an ebb and flow variant with a 4x8 tray. I expect some to give over an oz but others will probably only bring 1 oz ~. So yes you can get it for sure. I wouldn't let anything grow below the bud site, including other bud sites, except maybe a fan leaf. Keep all the plants energy going up to the top and no where else. Know what your strains ppm limit is and stay just below it especially in the beginning. I use RAW B Vitamin and feed them this a couple days before I do whatever I'm doing to stress them (repotting, cutting clones etc). As far as how many nodes.... just depends on you. Im going big and I don't want to have to deal with anything accept the top bud, so if I have any nodes not the plant other than the top bud site I won't let anything grow at the nodes. Unless there's another bud sight right below the main one that would grow into the top bud making a larger bud. Good luck, Id like to know how you did if you could.
