Have you heard of VPD? Check out the VPD chart to see what the humidity should be for the temperature you’re running. For example if you’re in flowering and your temp is 80F, then your humidity should be between 44-62%.
Between high temps and high humidity, high humidity is generally worse in flower as it risks mold and mildew. However, consistently high temperatures also affect bud density, trichome development, and aroma.
