The ideal temperature for the vast majority of plants is between 20 ° and 25 ° C elsius.

Avoid exceeding 28 ° C which corresponds to an acceleration of transpiration in plants, as well as a delta of 10 ° C difference between day and night.

Ideal moisture when growing plants is 80% relative humidity with constant ventilation, and when blooming moisture 60% (regressive at 40% at the end of the cycle).

Low humidity should be avoided at 50% growth at mid-flowering plants; this gives rise to necrosis spots on the foliage.
