Based on hydroponic system trials

Position lights properly to achieve maximum effect. Keep LEDs 6-8 inches above plants. Adjust the height according to the plants' height on a weekly basis. Rotate plants every few days for even exposure. Reflective surfaces also enhance light efficiency in dark areas.

Select appropriate systems for indoor locations. An example of a hydroponic system suited for basement locations is the iDoo Hydroponic Garden. The closed-in design provides optimal consistency in humidity. Other units, such as AeroGarden, can be placed within cabinets. All of these units offer self-contained ecosystems.

The maintenance remains simple. Check water levels every week in a windowless environment. Clean the light panels monthly for optimal output. Check the growth pattern for signs of light stress. All of these routines will help you continue harvesting throughout the entire year.
