hello, i've been growing for about two seasons now and think i'am ready for cloning and there is just one question that i have and that is about the saranrap. Do you but the sarnrap over the hole clipping or only one the stem? oh yeah one more question when you put the clippings under the flors light is it all right for the light to touch the roots or do I still have to keep them well hidden from light. thanks for any help you can give.
