Ceramic Heat Emitters?

[Krispy]

I make all my controls from hvac parts so cant help ya there. Personally, we use hyrdoponics seedling heat mats. Hyrfofarm to be exact. We have ones designated to work within 10 degrees f room temp. A little pricy, but worth it we think.

But heres what i think will help you.



Ultrasonic humidifier, makes cool fog, not, hot, wet air. Cost $40 usd at my local target. The lid was supposed to be a elephant lol. Look closely it has feet.
3/4in or i think 17-18mm(did i get it?) Some fittings and a little insulation, about $30usd at local lowes.
1/4 turn ball valves. This is how you set your flow. The humidifier gets set to put off X amount of fog. Then you set your flow valves to each tanks individual needs and let it go.

We let ours run 24/7. A tank lasts maybe 3days. But it does the red eyes(bottom right), the whites(top right), my ball python(top left), and the firebellies(bottom right). So 2, 40g an exo terra small, and a 29g. Cheap effective, and the fog looks cool lol. All but the whites are planted. So the fog also makes planted vivs grow like mad. Makes for good moss growing. Pothos go insane and root into the air.

So hope this helps your humidity or someone else's.
