Excessive light will cause the clone to eat itself alive basicallyMTF-Sandman said:You CAN, but it's definitely alot easier under a small fluoro. Excessive light will cause the clone to eat itself alive basically trying to photosynthesize all that energy that's coming at it instead of putting it's stored energy into root production. I use a standard shop light for up to 4 - 35 site cloners and the clones usually don't even yellow before they root in the normal 8-14 days.
