Please note temps above 80°F (26°C) in the flowering stage will slow down bud growth and may cause them to become airy and loose. The heat can also reduce the
potency and smell of your buds. Keeping the grow room temperature under control is especially important in the flowering/budding stage!
In the heat, cannabis is also more susceptible to many problems, including
spider mites,
white powdery mildew (especially if it gets humid, too),
root rot,
nutrient burn (from increased water transpiration), increased stretching, wilting due to root oxygen deprivation, and reduced “smelliness” of buds (as
terpenes can burn away at higher temps).
