How do you drop temps in a terrarium?
Default

It looks like various stages of awesome and total $%&%. It isnt so pretty right now. Everything is in various states of sunburnt, or still new and ugly, or hanging on by a thread from when i overdosed. I sprayed ready-to-use superthrive instead of mixing my own, and half my stuff died. Toast.

I control it with a Neptune Systems Apex aquarium controller that i already had.Night temperatures are 50-55 F. It's set at 50 to power off, temperature rises to 55 then it cools to 50 again. Depending on the thermometer and where I place the temp probe, it could get down to 46 when the thermostat is set to 50. I went below freezing when I forgot to set the fridge to auto. Now i have an audible alarm now.

My day temperatures are set to 75.

My photoperiod is 14 hours, and I would call it high light. My light is a migro veg. I turned it down to 50% and things are still getting too much light, i think. Humidity controlled with an inkbird controller set to 90%. It has a differential value default of 5%, but I use 1%. Ive got a pressurized co2 set with a fuzzy logic controller to keep the co2 levels about 1,500 ppm. I already had the setup, so why not right? I like to think it helps.

I have two 120 mm fans at the top blowing towards the front glass where it travels downward and two at the bottom blowing underneath the wire shelf and over the fridge evaporator. Flows back upward to the top. When the humidifier is on, you can see a circular gyre of air movement. That is important since I rigged the evaporator horizontally on the bottom instead lf vertically like itis supposed to be. I got a couple extra inches of width that way.

Your forum sucks for posting images.... Here is an old picture when it was new and lush and presentable.
