Placement options for effective plant lighting
The efficient nature and low heat loss of GroFlex allows for a wider
variety of mounting and placement options than high-output, overhead
grow lighting. Indoor horticulturists must rely on available space, and
GroFlex is designed to perfectly conform to your unique growing area.
GroFlex can maximize your plant’s growth by providing light where
overhead grow lights don’t reach. Use it to create arrays of GroFlex
on a backing wall, or a line of light on the inside lip of your planter or
pot. You can even hang GroFlex from overhead to follow the stalk of
the plant beneath the canopy. Any of these methods will provide more
plant-tuned light energy that could not come from traditional fixtures.
The ability to make tight turns also makes GroFlex perfect for creating
custom patterns. Use a zig-zag or spiral pattern to create a concentrated
array that fits your space. While every species is different, in general, plants
cannot receive too much light. The more GroFlex that can be directed
towards your plants – and the closer it is – the more they will benefit.
GroFlex can supplement more powerful, but limited-application,
overhead grow lights or fill in for reduced sunlight in shaded windows
or during winter. To use GroFlex by itself to grow plants, it’s important
to understand the light requirements of what you want to grow.

Troubleshooting
GroFlex LEDs do not light:

Make sure your LED power supply is receiving 120-volt power.

Confirm you have maintained correct polarity (+ to + and – to –)
when joining strips of GroFlex and when connecting to the 12-volt
power supply.

Check all GroFlex connections and any switch connections from
the power supply to the GroFlex strip. Consider testing with a
multimeter to ensure light strip is receiving 12-volt power.
Only part of the LED tape light strip is lit:

Check connections to the part of the GroFlex strip that is not lit.

Confirm that you have maintained correct polarity to the unlit section.

GroFlex is made with three LEDs connected as one series. If you
experience a partial failure, you can carefully cut out the damaged
section and splice in a new section as needed to repair.
LED tape lights blink on and off:

Your power supply is not adequate for the length of GroFlex you are
powering. Install a higher wattage power supply or reduce watts
used by shortening the lengths of your GroFlex.
LEDs farthest from the power supply are noticeably dimmer:

This is the result of voltage drop. Decrease the length of the
12-volt power feed wires or use thicker power feed wires between
the 12-volt power supply and the GroFlex lighting.

Use shorter lengths of GroFlex. Refer to Power Supply Size in these
guidelines. Consider a different configuration.
