Here's my build

In my 1.2 m tent humidity climbs up to 80 when the light goes off i put a dehumidifier in,it took out moisture but the levels never went down on the thermo!!.
I have to put heat tubes on half hour before light goes off and open the top of the tent a little to get it down to around 60%.its only thing that works for me,the dehumidifier just dont cut it.

Yeah dude ... i got the same issue. What ido, id that i keep the extraction fan going even aftwr the lights go off. Humid air out and fresh air in... i dont keep the oscillating fans on when the lights are off though (maybe i should?). The extraction is from top of the tent and freah air goes in from below the scrog screen. The direction of the ventilation in the tent is upward ..... some days can be very humid at night in the 70s. But thank God I havent had any issues with mildew n rot

These are going up tonight....

After cleaning up the wiring and hanging it, this is the view of the room.

You get back in weed, what you put it in at the start.

I admire the way you have searched for that great environment, that Mary Jane needs and loves so much!

The cobs are a nice touch! Love the drainage technique too.

Happy growing in your new room
