Hydroponics is the process of growing plants, flowers or vegetables without soil. This ancient art dates back to hundreds of years ago, with the Babylonians, Chinese and Aztecs using some form. Hydroponics produces better quality plants with fewer diseases, and encourages faster growth rate. Today, many gardeners grow roses hydroponically using NFT, or nutrient film technique, which supplies a constant flow of nutritional water to the roots of the plants. Commercial and home gardeners use this popular method of growing hydroponic roses.
Assemble the NFT grow system according to manufacturer's directions. It should include a reservoir, a pump, a nutrient solution air stone and a grow tray. Place the reservoir on a table in a sunroom, garage, porch or sunroom, and place the pump next to it. Position the grow tray at an angle above it.
Spread rubber stall mats around your grow system to prevent the area from becoming slippery. Also suspend grow lights above the grow system to supplement lighting. Keep in mind that roses require six to eight hours of sunlight everyday.
Immerse the roots of rose seedlings in a bowl containing distilled water for 10 to 15 minutes, to remove any attached soil. Plant the seedlings in net pots included in your grow system.
Mix growing medium according to the manufacturer's directions on your system. Add the medium to the NFT system.
Check the pH level of the solution daily to ensure it remains between 6.5 and 7.5. Any changes in the pH level prevent the roots from absorbing nutrient solution. The roots of the rose seedlings will extend through the net pots and into the water.
