Why does water appear on top of leaves?
You may see some water on top of leaves, usually in the AM once your grow room is filled up and the leaves of each plant are close and/or touching each other.
As you may know Marijuana, like all plants, sweats through their leaves. Generally you don’t notice this since it’s such small amounts is dissipates right away.
When another leaf is too close or touching it, that sweat can’t dissipate and starts to accumulate (condensation), that’s what you’re seeing! Basically, it’s like dew, water condensing on your leaves.
This happens especially at night time since the temperatures are lower and cannabis sweats a more during its respiration phase.
That’s it! all you’re seeing is the condensation of the water your plants naturally sweats.
