Another tip I never shared for cloning but I thought I should mention. When I get ready to clone I pull my lights from my plants and make them far away like 36" or more. This causes the plants to stretch like crazy between growth nodes and allows for a better cutting with a longer stem without all the branches to cut away to dip for the cloner. Fits nicer in the puck.
After cloning I slam them again so my tops take right off again tightly
