tips & tricks
Depending on the locale of an indoor garden, most air-quality
issues come about as an excess of humidity. Moreover, if one is
running a hydroponic system, the presence of standing water
in tables and reservoirs greatly increases the relative humid-
ity in a room. There are a variety of reasons as to why cultiva-
tors must maintain proper humidity levels in their growrooms.
For the most part, properly balanced humidity in a garden
helps plants combat airborne pathogens and ensures appro-
priate nutrient uptake. To illustrate, both powdery mildew and
botrytis thrive in poorly ventilated, humid conditions. Also, if
immersed in overly humid conditions, plants tend to pull water
directly from the air instead of through their root systems. This
phenomenon can cause issues with both overwatering and
malnutrition. Air quality issues relating to excess humidity
can be rectified with pro
