Right on man! I'll have to post a pic of the crazy planter we built a few years back. It's raised to waist height and self watering (as self watering as can be lol).
Happy Hump day!
Here's the planter I was talking about. The construction was pretty heavy duty since it holds a ton of dirt plus water, so it took a few of us to put it together. The whole thing is lined with heavy duty plastic sheet making it water tight. In the bottom is a bunch of perforated drain pipe sheathed in a sleeve/sock. The water is delivered via that PVC pipe you see sticking up. The PVC tube was cut at an angle and then stabbed down in to the drain pipe. On the bottom back of the planter there's a whole drilled with an external drain hose that lets the planter keep about 4-6" of water in the bottom (had to do some sealing to keep from leaking with a copious amount of duct tape). The plant roots draw the water from the bottom once they get long enough.
It's held up pretty dang well for the last few years and makes it easy to keep a small veggie/spice garden. Less watering, and less bending over to pick stuff lol.
"watering pipe" is front right
You can see the drain hose on the back bottom portion
Here's the drain pipe used to create the water holding area (super cheap stuff from the hardware store
This year I'm just growing 1 tomato plant, 1 poblano pepper plant, 1 bell pepper plant, 1 jalapeno plant, and some parsley. Went way overboard last season lol. The blue containers in the one pic are more planters built on the same concept, but I'm not running them this season.
