you’re right clones need very little light and some could root all the way based on stored energy only but most can’t. Couple things that are false about your comment: roots most certainly grow in the light. If they only grew in the dark autoflowers wouldn’t exist and begging plants at 24 hours would be impossible. 2nd thing is plants don’t need roots to photosynthesize. Photosynthesis occurs when the plants solar panels (leaves) pull energy and vitamins from the sun to use as stored energy. That’s the whole reason you have to use it weak light during the cloning process and it’s also good to cut bigger leaves in half to slow photosynthesis from occurring. Too much light will cause the plant to photosynthesize too much and use that energy to produce more leaves but it without roots it will burn the energy and die. with a Weak amount of light the cutting will balance storing energy and producing roots. It’s important to rememember with photo light period plants that even as a cutting, leaving the plant in continuous darkness will cause it to think it’s the end of the season and time to flower. Plants in flower get more darkness and root growth slows.
