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.
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.
