So my four girls are budding in my little greenhouse ontop my balcony. My question is that it hasn't been all that sunny out lately, or not sunny the whole day will this affect my yield?
I would presume that it would. Plants need light to photosynthisise wich equals food wich equals growth. fan leaves feed the buds that are growing on the same stem. get some supplemental light my friend. You will get a harvest if not but it will probably be long stretched out airy bud.
