The Medic Grow 660W Fold-6 LED Grow Light for indoor plants covers 4 x 4 feet for both vegetative and flowering stages of plant growth. It can be used in a tent for personal growers or chained together with up to 75 fixtures in a large commercial operation. This popular indoor plant grow lamp consists of six lighting bars designed to distribute light as evenly as possible throughout the plant canopy. In addition, this LED grow lamp features a completely customizable V1 spectrum to accommodate each phase of the plant's life cycle.
With a high efficiency of 2.8 mol/j and a power use of up to 660 watts, growing operations are more efficient. This light has an excellent PPFD of 1123 mol/m2/s at 12 meters and 845 mol/m2/s at 24 meters. This is sufficient to increase the production of your plant by 20–40 moles every day. Additionally, it is dimmable from 100% to 40%, allowing you to effortlessly change the light intensity during the veg and blooming periods.

The Fold-6 light distance and light intensity for all three stages depend on the species you intend to plant: 1) the seedling stage, 2) the vegetative stage, and 3) the blooming stage. Each development phase of your plant would require a distinct light spectrum and intensity. In general, we recommend an 18w fluorescent bulb hung at around 6" for the seedling stage, 30" for the vegetative stage, and 12" for the blooming period. You can adjust the strength of the photons at different stages of growth by adjusting the height of the light or using the dimmer.
