Takes a couple days of plant acclimation and the gardener fretting, but they get used to the warmer temps. I'd never recommend a newbie go overboard, but a few degrees will not kill the plant.

Keep them hydrated, and keep the stale air and heat vented out as much as possible. I give my ladies a gentle "mercy misting" once a month to wash-off dust and lint. Other than that, they never get misted, especially when growroom is hot.
