Hey Dirt, I'm interested if you would ask your buddies a question, I understand their pruning concept how they do it , but I'm wondering if they ever did it the way I do on a large scale and compare both ways , wondering if there is a difference., I don't prune until in flower , depending strain 8/9 day mark or 11/12 day mark depending on how long the stretch is, I prune the entire plant at once leaving a few nodes at the end of each branch, but they still add another node or so anyhow in the last week of stretch , in the end we end up with the exact same thing , their doing it over time i'm doing it all at once, without question it makes for a better product with a lot less trimming time, I wondering if they did both ways in a big room and noticed any difference in weight or size of plant in the end.
