How high above the plants do I need to hang the light?
In order to allow the light to "spread out" and cover your entire growing area, it is important to have your Black Dog LED grow light the correct distance above the top of your canopy. Whether your plants are vegetatively growing or in flower, the correct hanging height is dictated by the size of the area you are trying to cover.
Keeping the light too close will cause the corners and edges of the light footprint to be too dim- and our PhytoMAX lights are much more intense than some other LED grow lights that need to be kept only a few inches above plants- having our lights too close can cause "bleaching".
Please note that these are recommended heights and if you are reducing the light intensity to adapt plants grown under other lights, the heights should be adjusted accordingly. Increased grow light height above plants will decrease intensity and give a larger footprint, and hanging the light lower will increase intensity but decrease the footprint. Please contact us with any specific LED grow light distance questions for your own setup.
To determine accurate LED grow light height for your situation, choose the correct model from our selection of lights and enter the size of your growing area here:
Footprint width:
Footprint depth:
| Recommended hanging height above the average top of the plant canopy: |
| Total area covered: 2 |
|
Average over this entire area for runninghours per day: (calculations assume reasonably-reflective walls around the footprint and/or adjacent lights) |
We have custom, proprietary light modeling software that can show you guaranteed light intensity levels for every square inch of your growing area, or even every cubic inch from top to bottom. Contact us through email or phone or schedule a large-project consultation.
