The grow is going pretty well, plants look good except for one the leaves are yellow/ brown but I have been doing everything the same for all plants.. Anyways I have run into a dilemma, I have to go out of town this weekend Fri-Sun, and I have noone to water the plants. I have been thinking about setting up a self watering system with a pump and a drip system but im not sure how to go about it. Anyone have some advice?
