In this photo, I couldn't tell that was screen in the middle- https://ibb.co/Vqx484n Thanks for the added photos, now it makes sense. So apparently there's just not enough ventilation to dissipate the amount of water you added into the coconut fiber substrate. Having used the same stuff a few times (long ago), it's easy to get it too wet. How you prefer to dry it out is up to you.
(Many glass tanks have all screen on top- that's not the case with yours though.)
If you spread some in a large metal baking- or-lasagna pan to "bake" it, you wouldn't necessarily want to bake it dry- just accelerate the evaporation of the excess water. As I said, on a low temperature (150* F- that's 65.5* C, btw) it's quite safe- but for something like an hour, & under observation. Sun isn't as hot (even if you live in the desert) so it takes longer, that's all. Your call.
I've never used a 'vaporizer' but while that would work for solid items, it sounds like it might dry out & then blow your substrate around? That might be messy?
Different ways to get to the same place- your choice- & it's not a huge "emergency".![]()
