I'm in Thailand, its the rainy season now. I never had this happening, I never had water condensate inside the greenhouse like that. Its falling on the plant like if it was raining…
Is it due to colder weather ? Since a week the weather is colder, I didn't had this situation at all happening to me until now. What can I do else than keeping it open ?
I've fans blowing all night on the plants but it didn't help

Dehumidifier maybe
The higher humidity inside the greenhouse is condensing on the colder frame, and the high humidity will quickly foster fungal diseases and prevent plants from transpiring. You can:
1) Increase the temperature above the dew point: a radiant heater + fan can keep the air moving & uniformly heated.
2) Decrease the humidity: More air exchange, if the temperature isn’t too cold for the plants – a cracked ceiling vent or small ventilation fan can help avoid moisture accumulation. A dehumidifier could work, but it is likely to be a lot of water for a dehumidifier to extract. Many dehumidifiers (particularly the small peltier/electronic style) aren’t effective at low temperature – look into rotary dehumidifiers, which use a dessicant (like silica gel) to extract water, and are more effective at low temperatures. You may want to consider a continuous drain (rather than a tank), or an automatic pump, to avoid having to empty the dehumidifier tank daily. As a side benefit, rotary dehumidifiers double as a low-level heater, so you’re getting a nice combination – reduced total water vapor and higher temperatures == lower dew point and less condensation.
3) Reduce the water being emitted into the air: water less, or less frequently, if possible. Don’t restrict the airflow into the pots – the plants need the soil to breathe and dry out. If you’re looking to put plants into dormancy, you could also prune some plants back to reduce total transpiration.
I would probably open the ends and put fans on the plants full blast. You won’t be able to control humidity but good airflow is next best option.
Yes it is the cold weather. I had one do this exact thing. You can try to heat the inside or try to let the humidity escape.
Just add a vent or a heater. Your plants are fine down to a hard freeze. Your plants are not fine with a ton of mold.
This other guy gave you a crazy long list for what looks to me a hobby grow. Just add a vent that stays open all
The time
Waterfall
It Needs more airflow inside . That’s all
Buddy you need to trim them plants. Maybe try topping a few of the taller branches. Them gonna be tall
get some fans going, once its 100% humidity outside then there isnt much hope.
