Circulation vs. Humidity

[travelfin]

Hi
been looking for the same answer, but found no real answer. Green houses have an air exchange rate between every minute to twice an hour. The high one is more for cooling and the low one is for winter. Had two terrariums for two years now and growing bare root, no pots. running exhaust fans 24/7 and watering by misting for 30 seconds every hour from 0800 till 1700 lights on at 0700 out 2100. In my experience the main point is where you put different plants. High up dry or low moist and lightwise low or high light. I look at the roots, how are they doing and change the position accordingly. With potted plants that is difficult. Posted pictures two terrariums.
In my experience a plant can grow perfectly then suddenly it starts to wither, reasons due to the weight it drops lower or another plant grows in front and then less light or less water.
So what it's fun
