What I've noticed about cloning.
After sitting in straight water for so long they learn to transpire more to keep the water flowing up and out the leaves since there's no root system yet.
Now the water we clone in has no ppms except what's in the tap water.
It's basically suuuuuuper light feed they get used to while they consume themselves for root regeneration coupled with survival needs like food production from light.
Once removed from the %100 water media with low,low ppms. Then placed in soil (dryer style media compared to water).
The soil has much more nutes than the plant has adapted to in the water.
So it can seem hot the first few weeks. But as they grow in the new leaves will adapt and turn healthy green.
I've noticed a seedling born into my soil has no indications of hot soil.
But once a clone is taken & roots are established I transplant into the same soil. It seems too hot before they adapt. This is my indicator of what's happening like stated above.
They also start drying out.
Once removed from the water where they transpire heavily. And placed in soil. Access to large amounts of water is diminished.
This means the plants shed more than they can take up through the newly established small root system.
In time they adapt and slow down the release of water when they realize what's happening.
So
What I do is wait for them to establish a good root system in the cloner.
Then once transplanted the small pot gets fully watered. Now %90 of the time I use no dome. It takes a little longer to recover and If the root system was not established well they can dry up and die with roots still healthy and intact.
The other option is to use a humidity dome, zip lock bag with holes in it, or a homemade humidity area.
This slows down the release of water allowing the plants retain the development speed from not drying out and having a stress response to save itself.
After a few days to a week remove the bag or dome and let them adapt to the new environment.
Just based on personal experience coupled with too much analytical observation lol.
