The beauty of indoor grow lights is they allow herbs, seeds, houseplants, and flowers to flourish year-round. However, they need the right amount of sunlight and darkness to thrive. Johnson says that for germination and seedlings, you can run lights to hours per day until they are a few inches tall. &#;As they mature,&#; she adds, &#;you can slowly reduce to get them on a similar light pattern for spring before you transplant them.”

Light intensity is only one of three key components which ensure proper growth. Soil condition along with the proper amount and frequency of watering round out the other two components. You should learn about your plant’s growth cycle to maximize growth and reduce challenges along the way. By doing so, you can select the proper model and light spectrum combination to provide sufficient lighting. We suggest regular inspections to confirm that plants are on the correct growth track.

This modular unit from Gardener&#;s Supply Company allows you to grow plants vertically and expand as needed. Measuring x . x inches at its base, the compact, stackable design frees up precious floor space. Each shelf can hold up to pounds, and you can add up to two shelves—in addition to the base unit. When stacking two or more units, you may need to anchor it to a wall with the supplied brackets for added stability.

We love how versatile this grow light is: Thanks to a wide-opening clamp, you can attach it to almost any table, chair, desk, or countertop. It even has rubber pads on the clamp to prevent surface damage. Plus, the flexible gooseneck allows you to easily adjust the angle of the light. We found it to be extremely portable, easy to set up, and small enough to tuck away in a drawer. We think its compact size makes it ideal for households with a few small plants. You can even screw it into the wall for a more permanent yet space-saving solution, but keep in mind that you will lose the portability.

This depends on the type of plant, size of plant, and how many plants you are trying to grow.  A single light might be appropriate for a small pot with a single plant or a small seedling tray.  As plants get larger or the required coverage area expands, more lights may be needed.  Generally, if plants are growing well and have a compact, robust structure, they are getting enough light.  If plants are weak, with elongated stems and many small leaves, this may indicate additional light needs to be provided.  Up to eight LED Grow Light fixtures may be connected in series by using the integrated cords and receptacles in the fixtures.  Our LED Grow Lights come in several forms, which may be mixed to provide more light.
