You can find a leak-proof pan at a supermarket, pet store, or gardening store. Kitty litter pans are perfect for this.
Depending on the pot’s material, you can use a nail, thumbtack, or drill to poke holes in it.
You can try gravel or cotton batting as the medium. If you choose cotton batting, make sure to use an organic brand because cotton is often heavily sprayed with chemicals.

If you’re using a pump, set up your flood and drain system. Most people place the growing pan above the nutrient reservoir in a larger container. You’ll then need to connect the pan and reservoir with the submersible pump and tubing, so the pump can deliver nutrient solution into the tray. You’ll also need to install an overflow pipe to drain the solution back into the reservoir. For manual flooding, pour enough water to give each pot at least one cup. Drain the excess water into the pan by draining it into a bucket.
Find a leak-proof container to hold the plants as they grow. This can be bucket, tray, or other type of container. For your reservoir, you’ll need another leak-proof container (like a bucket). This container will hold your nutrient solution. The reservoir should be large enough to also support the growing tray, which sits above it usually.
Common materials that work as wicks include fibrous rope, wool, cotton, or rayon rope, tiki torch wicks, wool felt, and strips from old clothing or blankets. You’ll want to test materials to see what works best. Be sure that your wick is absorbent but resists rotting. You can improve the wicking ability by washing the wick before you use it. Have enough wicking material on hand, too. You’ll probably need at least two to four wicks, unless your system is extremely small.
You’ll next need to punch holes in the top of your reservoir and the bottom of your tray. Then, thread in your wicks and put the containers in place. Try to spread out the wicks evenly on the bottom of the growing tray. Add your growing medium to the bottom of the tray so that it covers the wicks. Wick systems need an absorbent medium like vermiculite, coco coir, or perlite. Flush out the medium with fresh water about every two weeks. This will reduce the risk of nutrients and salts building up to toxic levels.
Beans also grow well in a hydroponic system. The seeds typically germinate within eight to ten days.
Having too much or too little of any one nutrient can cause poor crop performance. It’s best to look for a commercial hydroponic solution that offers a full nutrient profile.

As a beginner, you may want to start with a liquid solution. It’s more expensive, but it’s easier to use. [14] X Research source
Wait until the bed is dry to remove the plant and shake off any particles that may still be attached.
You can control light levels with an automatic timer that controls the on/off setting of your grow light.
You can maintain a pH level of between six and seven by adding soluble potash or phosphoric acid to the nutrient solution, depending on the result of the test.
Make sure to follow the directions on the label of the type of pesticide you choose to use.
