A little update:
I haven't done anything major to the rack in terms of upgrade. All three used shelves are currently enclosed in the same way I have done previously. And all of the plants have been rearranged. There are small mods that I have done here and there as part of tweaking the setup, which are not worth mentioning. I will add pics of how the grow shelf looks currently later.
-On the top shelf (the warmest) I keep all of the sundews together with a small 7G heated terrarium (pics later) for petiolaris sundews that Crissytal so generously sent me, and two VFT that are waiting to be released into the wild (backyard).
-The middle shelf is home to the Pings.
-And on the third (lowest) shelf I keep all my utrics, Shpagnum growing chamber, and a lone Cephalotus HG (thank you GrowinOld). At some some point in the future I'm planning to convert this entire shelf into High Land chamber.
Currently, I'm saving up to purchase the parts necessary to build a cooling system.
Recently with a lot of help from GrowinOld I put together a small 10G self watering terrarium that is home to most of Epiphytic utrics (Thank you Ron! (RL7836)):
I have used, 90gph aquarium pump, egg crate as false bottom for the pots, styrofoam cups with cut off bottoms and holes made in the sides (to let the water flow through) for false bottom support, and a layer of landscape fabric on top of the egg crate to prevent pieces of soil from getting into the water. The pipes are 1/4 CPVC.
The water in the clip and pics is green, and was changed since then (the pics and clip are old).
I am a lousy cameraman, so forgive me for the quality of this clip.

The terrarium with no water flowing:

This is what I do to get the pots in and out
Terrarium, no water, my feet and socks.

In addition, right on top of the terrarium, there is a little fan that blows cold and moist air, that exits from the humidifier on the shelf above. And another fan that blows air in from outside the rack. This is not an optimal setup, and the top fan is exposed to extra humidity, but it is a temporary solution before I get the cooling system up and running. This way I can get the temperature in the terrarium to drop at night to 62F and it stays at 75-77F during the day.
