Here's what you need:
- Two 5-gallon buckets
- One 5-gallon bucket lid
- 1/2" PVC pipe ~20" long
- One can
- Burlap cloth (not shown).
I cut a notch in the bottom of the PVC pipe so it wouldn't sit flat against the bottom of the bucket. Then I drilled a 7/8" hole in the bottom of the bucket and put the PVC pipe through it.
I cut notches in the bottom of the can to allow water in.
Then I placed the inner bucket into the outer bucket and put the can through the hole in the bottom.
Then I put the burlap in place. It'll keep the soil from filling up the void holding the water.
Then I filled the bucket with soil. I made sure that the can at the bottom was filled first. In theory the soil in there should absorb the water and draw it upwards to the plants.
I drilled a hole in the center of the lid. That's where the plant will go. I also put the PVC pipe through the lid and used the top of a soda bottle for a funnel.
The last step was to fill it with water.
I'm anxious to see how this works.
