Elevated relative humidity can also lead directly to condensation. Moisture Control is the Key to Mold Control. Mold growth does not require the presence of standing water; it can occur when high relative humidity or the hygroscopic properties (the tendency to absorb and retain moisture) of building surfaces allow sufficient moisture to accumulate. The high temperature not only warms the house but also reduces humidity, which is an important factor for mold to grow. A central heater emits enough warmth to reduce the average humidity in the entire house, but it does not kill mold directly. These can quickly spread in a grow tent, and ruin an entire crop.
