LIGHT LEAKS
AND SEALED GROWROOMS
by Kent Gruetzmacher
Light leaks in your sealed growroom can
be disastrous for some kinds of plants.
They can also be a sign that more than
just light is getting in, including pests
and other environmental variables.
W
hen planning and setting up indoor gardens,
growers spend time and money in the creation
of environments where plant species thrive. For sealed
growrooms, this process represents a careful balancing
act between temperature, humidity, light, and CO 2 .
However, once an indoor grow is operational, these
synthetic environments create challenges for growers
that are non-existent in the natural world. The reaction
of indoor plants to light leaks during dark periods (night-
time) presents one of these unusual phenomena.
