DIY Indoor Hydroponics


Gardeners who choose to grow their plants hydroponically often do it indoors. It lessens the likelihood of pests or bacteria, but requires more preparation. A grow space for a hydroponic garden can cost over $500, if all the proper equipment comes from a retailer. You can set up the equipment do the planting in a day or two. Once all equipment is running well, the plants will grow optimally, providing abundant blossoms or yields.


Step 1

Tape the plastic sheeting to your walls ceiling and floor, and staple over the tape to ensure the plastic stays in place. Wipe down the plastic with a cloth and bleach water solution.

Step 2

Place the oscillating fan in any corner of the room, wherever it can turn freely. Position the climate control system, air purifier, and CO2 tank along the wall to maximize your floor space. Set the flow meter on your regulator to .06 cubic feet for every 1,000-cubic-feet of room space. When the plants are in the room, turn the gas on.

Step 3

Mount the HPS light to the center of the ceiling. The light should hang three feet above the floor and one inch from the ceiling. Plug the ballast into a timer, and plug the timer into the wall. Set the timer at 12 hours.


Step 1

Set your net pot upside down on the center of the bucket lid, and trace around the net pot with your pencil. Measure an 1/8-inch towards the center of the lid, from the traced circle and cut out this portion of the lid with a knife. Cut another hole one inch from the edge of the lid that is ¾-inches in diameter. The power cord to your pump will go through the ¾-inch hole.

Step 2

Place the water pump in the bucket and set the flow control on its lowest setting. Connect the ¼-inch tubing to the water pump.

Step 3

Set the net pot in the bucket lid and set your rock wool cube in the net pot. Run the ¼-inch tubing up through the net pot, alongside the rock wool. Put the dripper inside the tubing and position the dripper so it lies on top of the cube.

Step 4

Place the hydroponic system underneath the light. Be sure not to place the light too close to the plants. Your system is ready for your choice of nutrient solution. Run the water pump constantly.
