Just had an idea, that you could make a hydroponics set up without using pumps. If you let the bin sit outside on a hot day, the water in it, along with the nutrients, would be able to evaporate up and onto the plant roots. Maybe. I was just wondering if anyone had tried this before or if it would even work. There wouldnt really be a cycle between flooding and dehydrating, unless it was cold enough where it wouldnt be evaporating. So I was just wondering, would it work? If it did, itd be a hell of a lot cheaper than a nice hydro set up.
