Thanks for the additional information and pictures. Appreciate it.
Hope you don't mind more questions.
What do you have in the tray? I am so curious. Haa, haa... You may need to take out the shelf in the mini fridge when your highland neps grow up huh. The humifier is on the whole day or on timer?
Off topic... Is that drawing done by your kid? Looks like he likes cactus instead of CPs. I can see 2 pots of cactus in hi/her drawing.
