I found this pot at SH Hydroponics > Outdoor Self Watering Wick Planter
Basically it has a water reservoir underneath and some cotton wicks that poke up from it into the pot through holes in the bottom. I've heard these setups work great for household plants. The plant just sucks up water as it needs it. I'm thinking this will help reduce the frequency with which I've got to visit my plants to water.
What do you think of this setup? I found a 15'x15' brier/thornbush patch in the middle of a nature preserve I've never seen anyone near. No large trees around, plenty of sun. A freshwater creek runs about 50 yards away. The brier patch dips in the center, so it is almost like a little fort in there. The only way for me to even get into it is by laying some heavy carpet over the side and climbing in (those little thorns are fucking *sharp*). I'm thinking of setting a few of these pots in the middle of that thing. I figure I'll visit them once or twice a week to check up, and refill the "tank" with some water mixed with soluble fertilizer and LST the plants so they don't poke up out of the thorn patch.
