Growing Plants Under LED Grow Lights

Not unlike HID lighting, the coverage of your LED grow lighting will depend
upon the mounting height of the bar. Your mounting height will be
determined by the light requirements of your plants as well as your plant's
access to natural sunlight or other forms of artificial lighting. Determining
the ideal distance to mount each model will require some trial and error on
your part. We recommend that you begin by mounting the bars at the
maximum recommended height for the model you are using to allow plants
to adjust to the quality wavelengths emitted from our LED plant lights. (See
mounting height recommendations here.) Your plants should grow
vertically to a point (remaining compact). For more vertical growth simply
move bars back to maximum recommended mounting height.

As a general rules of thumb:
Estimated coverage area as primary lighting for each LGM3 is a 1’ x 3’ area
(30cm x 90cm).
Approximate coverage for the LGM540 is 1.25’ x 3.75’ (38cm x 114cm).

As supplemental lighting (greenhouse) the LGM5 is recommended, allowing
approximately 1.5’ x 4.5’ (46cm x 137cm) of coverage out of each bar.

Over low light greenhouse plants such as most lettuces micro greens and
herbs, an 8ft LEDstick containing 4 LGM5 bars will cover up to 5ft x 10ft
plot, as pictured to the right. Divide the square feet of your grow plot by 50
for the total number of LEDsticks needed for your lettuce/herb
greenhouse, and divide by 24 for total LEDsticks required for
tomato/pepper greenhouse crops. (1000sq ft needs 20 LEDsticks over
lettuce/herbs, and 41 LEDsticks over tomatoes/peppers.)

We typically use 33 degrees as the primary beam spread and 45 degrees as the secondary beam spread. The 33d
gives a truer picture of the 80% power point and blending of the LGM540 product. The 45d gives the light spread
out to the edge, minus much LED to LED overlap and blending. One shows the maximum coverage and one shows
the maximum growing zones of the bar.
