A group of up to 40 Luxx Lighting 645w LED Pro XR fixtures can be connected to both the main RJ9
port and the auxiliary RJ9 port of our NX-1 controller.
• Turn the dimming knob on all of the fixtures to “EXT” (external control).
• Plug the RJ9 end of one of the provided controller cables into the RJ9 main port of the controller.
• If a two room setup is used or if more than 40 LED fixtures have to be connected, plug a second
controller cable in the RJ9 aux port.
• Plug the RJ14 end of the controller cable(s) into the input of a RJ14 splitter. Use an interconnect
cable to connect one output of the RJ14 splitter to the RJ14 port of the LED fixture.
• Use an interconnect cable to connect one output of the RJ14 splitter to the input of the following
RJ14 splitter.
• Repeat this process to connect up to 40 LED fixtures per group.

UNFOLDING THE 645W LED PRO XR
WARNING! ALWAYS PLACE THE 645W LED PRO XR ON A CLEAN, SOFT SURFACE TO AVOID
DAMAGING THE DIODES.
STRUT MOUNTING PART LIST
Parts list for mounting the fixture to strut:

MOUNTING WITH HANGERS
• Allow an additional 25” from the top of fixture for the length of hanger.
• Locate the 4 eye bolts on the LED fixture and slide the hanger clips onto two opposing eye bolts.
• Be sure to hang from the center of the hanger.
SOLID DECKING MOUNTING
• Using the solid decking mounts, loop each mount across the crossbar above the LED light bar sec-
ond from the end of either side of the fixture. Use two decking mounts on either end.
• Once all four decking mounts are in place, lift the LED fixture up and mount it on the decking
mounts. You can do this by carefully prying apart the hooks until there is enough room to slide the
fixture between. Release the decking mounts and they will hook around the fixture.
• Adjust the LED fixture so that each decking mount makes as much surface contact with the fixture
as possible.
• Now that the fixture is secured to the decking mounts, you can adjust the position of the lights by
sliding the decking mounts across the crossbars and settle it in the appropriate location for your
growing operation.

GROWING WITH LED’S
BY POETRY OF PLANTS (IG @poetryofplants)
When cultivating under LED lighting, a cultivator might be tempted to execute a similar methodology
to HPS cultivation. This strategy can lead to frustrating results due to the environmental dierences,
higher usable lighting levels and subsequent higher photosynthetic rates that stimulate growth with
less room for error. The focal point of heat created by a bulb also helps burn o latent load (RH) which
doesn’t occur with a properly built LED fixture, which diuses heat into the ambient environment creat-
ed a more evenness to environment but also can cause higher relative humidity. Also, with LEDs more
input energy goes into created light than heat (which is the case with HPS).
This increase in light will stimulate higher photosynthetic rates, leading to higher transpiration rates
and a higher demand of feed solution, all of which add more water into the room. When specifying
dehumidifiers it’s important to match the dehumidification potential with the volume of water added.
With LEDs, it is safe to assume that the peak water demand per day will be 1 gallon per sq ft of canopy.
Remember this is PEAK water demand, daily water demands will in reality be less and dependent on
pot size, cultivar type, and plant age. For example, a 2-week-old plant will require less water than a 6
week-old plant.

Because of the higher photosynthetic and growth rates, plants that receive a higher PPFD will require
more food. It is recommended when first cultivating under LEDs, for the cultivator to match PPFD levels
used under HPS and make gradual increases of both light and fertilizer PPM during subsequent runs. It
is also recommended that the cultivator uses a quality PAR meter that measures PPFD (umol) to under-
stand how much light they are giving the plant.

HOW TO ASSESS APPROPRIATE PHOTOSYNTHETIC RATES
Use a laser thermometer to measure leaf surface temperature. Under LEDs the leaf surface temperature should
be at or around ambient canopy temps (2-3 degrees dierential). Transpiration generally cools the leaf surface, so
if your leaf surface temp is climbing 2-3 degrees higher than ambient canopy then the light energy is not being
turned into phytochemicals (which is desired) and instead is being reflected back as heat (undesired and used
to cool down the plant). If the plant is heating up above the ambient temps then you need to dial down the light
intensity until the stress is resolved. If this occurs for multiple days, then you should also dial down the fertilizer
concentration, feeding the plant more water to help cool without leaving a buildup of salts in the media (which will
choke the roots, aka osmotic root pressure). You should also perform daily pour through run o tests to make sure
the media isn’t becoming acidic and the EC levels are close to solution EC level).
