I had an issue with the heat mat not turning off properly and the clones I had were at the 6th day looking good and under a dome with vent cracked, I didn't catch it for 24 hrs and it got to 32c under the dome, which cranked the humidity back up over 90% and consequently caused stem rot in the coco, they all folded within 30 hrs.
So anyway I made a setup with the cloning tray and dome sitting on top and inside the lip of a bigger tray, I drilled 3 air intake holes in the bottom of the clone tray, and then filled the bigger tray with water until about an inch under the tray with clones, then I put the heat mat under the water tray and keep the water at 27c, this time I put an inkbird controller on the heat mat.
The room also has a inkbird controlled heater that turns on if the temp inside the dome falls under 23c and turns off at 25c.
Why Im going to all this trouble is because I have a 20c swing in temps from night to day and its a pain to regulate in my grow area, so anyway with this setup inside the clone chamber sits at 24c and 90% humidity with the dome vents wide open; there is barely any condensation just a very slight fog on the dome walls telling me there is good airflow flowing through the dome.
In cloning I've never liked the idea of 90% humidity that is dead still air around the clone then having to play Roulette with either rotting the clone or slowing rooting etc, with my climate ambient swings, I can lose things very quickly if anything fails or I miss something.
Ive had to take replacement cuttings from plants 7 days into flowering, they are looking great under the dome and all perked still praying like they were on the mother.
My question is, do you guys think this high humidity with constant air flow will cause any problems, would the airflow put transpiration stress on the cutting, or I'm hoping to be at such high humidity will be the same as if it was a closed dome but without the bad things like rot.
In my mind it seems like it would be perfect conditions for cloning like sitting in 90% humidity jungle at 24c with good airflow, but Ive been wrong before when trying experiments, all I can think of here is whether the clones will have transpiration stress, will find out soon enough just thought I see what you fellas think.
