2. Prepare the Wick
Cut a strip of cotton or fabric long enough to connect the soil to the reservoir. It should absorb water well.
3. Build the Reservoir
Place a smaller container or the base of a water bottle at the bottom of your planter.
Drill one hole for drainage and another for the wick.
4. Assemble the System
Thread the wick through the hole and into the reservoir. Fill the container with potting mix, burying the wick well.

Pour water into the reservoir. Add your plant or seeds on top.
Top off the reservoir every 7–14 days, depending on your climate.
