humidity spike?

Ofc it is, the process of photosynthesis involves capturing photons of light within the leaves, The plant then goes through a process of converting the captured light "energy" and transferring it into chemical energy in the form of starches and sugars, the plant uptakes a little water from the rootzone and mixes it with a little co2 which it breathes in via the backside of every leaf using a million little mouths called stomata. As a by-product of the entire process the plant creates oxygen and water. Bud flowers themselves photosynthesize although not nearly as efficient as leaves at capturing photons it is still a marked increase in perspiration
