Ever seen a leaf sweat?

My leafs appear to be sweating from the tips? Anyone ever dealt with this?

They need more airflow brother.

it’s called transpiration… if the leaves are touching or overlapping, the water that the plant loses through transpiration can be trapped on the surface of the leaves forming water droplets… during flowering it can eventually lead to mold… try to increase your airflow if you can…think of it as sweat…suffocated by another leaf laying on top of it. This is why defoliation is useful. The leaves breath out through the stomata on the bottom of the leaf. When they overlap another leaf, that water can condense on the leaf under it. That pocket of moisture is a microclimate that can support less desirable life forms.

Also the best way to avoid this is staying on top of your VDP. Here is a great calc. Type in ur current rh and temp, it will show ur VDP. Make sure to check chart to see if ur in correct range. ideal VPD for the vegetative stage is around 0.7 - 1.0kPa . VPD for the flowering stage should be around 1.0-1.4kPa .

As long as your airflow is solid you should be ok. In flower, though, make sure that the RH is low. Less than 55%. You don’t want all that moisture on your flowers.

Did you keep your tent closed and lights on?
I did that with the babies’ tent sometimes.
The walls of the tent were wet and dripping. I increased ventilation because they are big babies now, still not into flowering.
When they are a few weeks old high humidity it’s good,

It was. And yes, the walls were sweating as well. We had a front blow through and all was dry this morning. Fans are on the way. Thank you everyone for responding. :+1:t4:
