Ah ha thx. Yes right now I have a few hovas going. They just dont hold but 1-2 clutches. I use sealed containers with vermiculite in them and that seems to work. So if the heat stays at my 90.f range the humidity will be fine in the tubs. Just wanted to check bc with the hovas I put the water in the bottom. I didn't exactly know how I'd do that with the fridge conversion. Although I've seen folks use the fish heaters in water or putting the heat under a tub of water.
