How to Make a Hydroponics Grow Kit


Hydroponics is a system of growing plants using water, no soil, and either wicking mediums or a specialty medium mixture to deliver nutrients to plants. Plants grow between 30 and 50 percent more efficiently using a hydroponic growing system because they constantly have nutrient-filled water flooding their root systems. According to HID Hut, roots of plants in a deep water culture system do not need to spread far and wide to find nutrients, since their roots are suspended in nutrient rich water that has been oxygenated. (Reference 2) This allows the plant to flower and fruit more efficiently. You can create a simple deep-water culture hydroponic growing kit at home and start growing your cuttings in no time.

Step 1

Place one empty planting pot on top of the lid of the rubber tub. Using a black marker, trace the outline of the bottom of the pot. Do this up to eight times across the lid, filling in the area with circles.

Step 2

Cut out the circles slightly larger than they were traced using a box cutter or razor blade.

Step 3

Cut a small hole the size of a nickel into the bottom of each jiffy pot. Cut coconut coir in a circular shape to fit into each jiffy pot.

Step 4

Slice a small slit into the bottom of each round piece of coconut coir to thread the plant root into and through the bottom of the pot. With the plant in place, add 1/4 cup of vermiculite and 1/4 cup of perlite until the plant is held in place. Set aside.

Step 5

Cut a small hole about 3 inches below the top of the lid approximately 1/2 inch in diameter. This is where you will thread the air line tubing into the tub.

Step 6

Connect one end of the tubing to the air pump. Connect the other tube to the blue aquarium air bar and set it in the bottom of the tub.

Step 7

Fill the 5-gallon tub with approximately 4.5 gallons of water. Place the jiffy pots into the holes cut in the lid of the tub. Snap the lid into place. Make sure plant cutting roots are touching the water in the tub.

Step 8

Plug in the air pump and turn it on. Monitor your hydroponic kit closely. In two week there should be some considerable growth in the roots of the plants.

Tips and Warnings

  • Use caution when working with razor blades. Place your air pump in a location where it will not get soaked with water in the event of a spill.
