Bloom Bros Hydro Halos. Extremely overpriced plastic horseshoes. I attach tubing but use a funnel and hand water. Makes reaching in the tents a lot easier on an old timer like me. Plus they distribute the water more evenly than I could. The tubing is short right now, can probably see the end hiding behind the pot. I know I could go pump/timer/res but I have lots of time to putter about.
Eventually I will cut a hole in the side of my tent and slip the hoses through it so I can water without opening the door. Lots of tape and reinforcement around the cut. I'd like to eventually install a wide grommet.
