So I had an idea for an automatic watering system for my next grow. I will only be growing 2 plants right now,just for personal use. My idea involved hanging or mounting a 5 gallon arrowhead bottle above the plants and have a timer activate a valve to allow a certain amount of water to flow. I'm just trying to get some opinions on the idea and see if anyone is using a system lilke this. Also was wondering if directing the water to the bottom half of the pot would help build a better root system? Thanks for all the help.
