I have been reading about the fimming process to maximize yields, and have 2 questions that I have been unable to locate answers on. 1. Is there a minimum age/size/height a clone should be that will support the fimming process without endangering the clone? Is there a minimum time after fimming takes place before moving them into a flowering light phase? Thank you for all the input.
As long as the clone is established with a good root system, you can do anything you want to them. You should wait for the fim to grow out a bit before flipping to flower.
