Fuck a jay if you want to save weed. If you smoke a bowl put a quarter over the top of it so it puts the bowl out when your not hitting it. Ghost the hit...dont let any smoke out. Hope that your weed is some chronic.
There is none...leaves take the light and make it into energy. If anything people talk about cutting leaves to let the buding tips get direct sun but i just bow my branches out to do that.
