Why does water appear on top of leaves?
The very short answer… your plant is just sweating and that extra water had nowhere to go 🙂
Water generally appears on top of leaves during the night cycle. It is likely that you have a full grow room with leaves close or touching each other. You open your tent in the morning and what do you notice? Little areas with water on your leaves
As you may know Cannabis, like all plants, sweat; And they do so through their leaves. Most of the time we don’t notice it since it’s such small amounts of water and it dissipates right away.
But.. when 2 leaves are close, or touching each other, that sweat can’t dissipate anywhere. It starts to accumulate and condensate, and that is what you’re seeing!
Basically, it’s like dew, water condensing on your leaves.
Why does this happen more at night time?
There are 2 reasons. The first, at night the temperatures are lower and the humidity level is higher. This makes the evaporation process slower.
The second, cannabis sweats a more during its respiration phase.
This water is simply the condensation your plant naturally sweats.
