¿Se puede hacer un clon a partir de corte de topping?

Okay. So, you're talking keeping the bit you took of? Clones are something you take when you know you've a good pheno and want to cash in on it. Also, you don't put freshly cuttings and put them under light. Only need ambient light when there's no roots. As you're not needing the plant to do photosynthesis. You need it to build roots. So a rooting gel or hormone is needed. (Not a must) but will help you along the way. As for what you've taken. Find a nice warm place with ambient light. Beside your grow tent. (To the side r wherever you have no Direct light)
