Outdoor hydropnics help please
I want to start growing some of my plants hydroponically and so i have been looking into making my own system. The problem is that im wanting to do it outdoors as i have a pretty small flat, also i have a shared garden and so i cant get any electrical appliances outside i.e an air pump. Is there any way that i can do it outside without having to use electrics and hopfully not spend a lot of money? any help appreciated, thanks.
