I usually flower four plants, each in a 15 gal fabric pot indoors in organic soil. Sick of hand watering. I've seen folks use chapin sprayers like drip emitters, and would like to emulate that but perhaps it could be improved upon? Anyone have any experience rigging up indoor drip irrigation with hand pumps of any kind? Don't wanna use electricity if I don't have to. The girls like about 3/4 gal per day, ideally I wouldn't have to water them individually thank you!
