Just Switched To Coconut Fiber Husk

The substrate is no where near that wet, I didn't even wet it. But for some reason it caused water to build up along the walls of the tubs. On a positive note, my Mojave was going into shed and she had a PERFECT shed over night, right when I put the coconut in.

anyone?

Coco coir holds tons of water, I usually will keep it slightly damp it is darker damp that bone dry. I can't do much more than guess as to your condensation, you said that the coco was dry really dry or slightly damp I when adding from a loos bag will hit 88% for a day or two it just holds water. The second guess is that as you change the way the heat is applied to the tub it will change air flow and if the substrate is now altering the air flow and you are getting more warm air on the cool side you can get condensation. Just thoughts with out being there it is hard to guess.
