Beets are root vegetables that are both straightforward to grow and useful. They are generally a deep reddish-purple colour but can also grow in yellow and white. Beets grow best in the cooler temperatures of spring and fall. Like most vegetables, beets will thrive in indoor situations like hydroponic gardens, though they do require some specific considerations. If you want to grow your own hydroponic beets, make sure that your hydroponic garden is large enough, and provide the right lighting, temperature and nutrition requirements.
Prepare your hydroponic garden. Make sure that the growing pods are large enough for beets, which need to grow inside the pots instead of above them. Connect the hoses to the water circulation system and set the pods in a row in front of the garden for planting.
Fill the growing pods with peat moss, sand or gravel for hydroponic growing, which utilises non-soil foundations. Use a loose foundation rather than steel wool or vermiculite, which is tight and may restrict the beets' ability to develop.
Plant one beet seed per pod, 1/2 inch deep, then put the pods into the growing system and connect them to the water hoses, per the directions that came with your garden. Hydroponic gardens automatically circulate water over the roots of the plants but require hoses to do so.
Mix beet or vegetable hydroponic nutrient solution, available at hydroponic retailers, with pure water for your system. Use the directions on the back of the bottle for the amount to give the beets the vitamins and minerals they would normally garner from garden soil. Fill the watering tray with this mixture, then set the system to give the beets at least 3 to 4 inches of water a week.
Put the garden in a place where it will receive six to eight hours of full natural or artificial light every day but won't get too hot. Beets do best with temperatures between 15.6 and 18.3 degrees Celsius.
Harvest beets on their timeline of 40 to 50 days. As root vegetables, beets aren't available for standard ripeness tests but are good for harvest at any time between planting and maturity date.
