No. When the plant’s xylem is full of water and stomata are closed, special pores are needed to release the internal pressure (kPa) like a valve, because roots have a membrane that allows water in but not out. Roots sitting in water during the dark cycle are very prone to this when the stomata are closed in the early morning hours. I use guttation as a way of knowing when a clone is rooted in a humidity dome. I don’t spray anything on my clones in a dome. So when I see what looks like little water drops on the edges of leaves, I know the clone has good roots and not enough leaf (stomata) to transpire everything.
