Idea for an UHL/HL growing setup for rajah/hamata

[NineTailedLeopard]

I wanted honest input for a setup I am planning to install indoors. I will start with small plants to see how it goes. Here's the general breakdown of the setup.
-Plastic custom built grow chamber made of white pvc pipe as a frame with tightly fit non transparent white plastic panels to prevent light and humidity from escaping placed inside an air conditioned room indoors (8'x10'x6.5')
-Light fixture with 4 6500k 100 watt 4' led gardener bulbs (1 led uva/uvb bulb swapped? Far red led bulbs where? Just speculating here, likely unnecessary)
-Plastic grating shelves with plants on middle shelves and distilled water trays on bottom shelves cooled by an aquarium cooling system and pump. PVC drainage and overflow pipe system can allow excess water in trays to be siphoned out easily using an electric aquarium siphon.
-Fan inside
-Lights and fan on timers for 14 hours a day.
-Aquarium cooling system and pump on for the last 10 hours overnight.
-Will likely start with very large plastic pots with drainage holes (24"+ diameter) and small plants to begin with to avoid repotting stress. All plants in 3:1:1:1 organic long fiber sphagnum, perlite, pumice, horticultural sand with top dressing of live sphagnum.
-Species include Heliamphora Ionasi, Heliamphora Tatei, Nepenthes Rajah or Hamata, Nepenthes Attenboroughi.

Honest and critical input appreciated. Thank you everyone!

I am new to this forum but started growing carnivorous plants about 6 years ago. Mainly grow lowland and some highland or highland/lowland hybrid nepenthes and heliamphora as well as tropical Drosera and Brochinnia Reducta and Accuminata.

How is heat exchange from your chilled water trays to the air happening in this setup? Just sitting in the trays won't be particularly efficient and I'm assuming you aren't using it to cool the plants directly.

Additional ac unit installed even though there is already ac installed inside. It rarely gets above 90 degrees here in western Michigan so keeping them cool is more efficient with proper ac.

Also a fan. Maybe I should have it on at night as well?

Also would having the chilled water with a layer of pumice or perlite be more efficient inside of a 1000+ glass tank with the plants and soil well above water line be more efficient? My concern is that they would get too big but it would be good for when there small given the tank is at least 1000 gallons. I generally don't like the idea of putting them in a massive tank so maybe I'll just have the fan running constantly as well as the ac and pump or a fogger.

It sounds like you are trying to use the chilled water for evaporative cooling in which case you wouldnt need to chill it and would have better results pumping it over a fabric layer. When people use chilled water in grow setups its to plumb into a radiator with a fan to produce cold air. Personally if you already have AC running there isn't much point in also doing a water chiller.

Also, Michigan should be cold enough most of the year anyway. You could just pipe in air from outside and cool with the AC during the summer.
