Thermostat?

[Balls Out Morphs]

Well it will work. But what you will realize is that your 28's might be at 90 degrees but your 41quart tubs are gonna be around 80. So thats why ppl buy two so now they can build or buy how many 28's and hook it up to one and make or build alot of 41's and plug to a dif tstat. Does make it sense?

I'm not an expert but I feel like you give out a lot of misleading information and are a bit confused yourself.

The thermostat the OP is questioning is as follows;

The VE-300X2 features include:

•Convenient table top mounting
•Two independent heating zones
•Full back-lit display
•Displays probe temp and set point on main display
•Hi/Lo History for each zone
•Hi/Lo Alarms for each zone
•Battery backup for clock
•Built in Night Drop capability for each zone (independent)
•Remembers settings during power failure
•Grounded receptacle designed for outlet strip use
•900 watt total capacity with user replaceable fuse (Spare fuse included!)
•10' probe cords (2)- user replaceable
•Stackable! Multiple units can stack for neat, professional appearance
•Pulse Proportional OR On/Off capable for each zone

By using this thermostat you will be able to run two completely different racks at two completely different temperatures. Tape one of the probes directly to the Flexwatt on the center shelf of each rack with heat tape. There isn't some "magical" temperature to set the heat tape in order to get the right temperatures inside the tubs because everyone’s setup is different and all require a little trial/error to get them correct. The best way to go about having the right tub temperature is to set up everything minus the snakes and over the course of a few days randomly shot the temps in the front (80-83 degrees) and in the back (90-95 degrees) of each tube with a temp gun and adjust your thermostat accordingly.

If you’re looking at running multiple heating elements you might wanna have a look at the Herpstat Pro, that’s what I'm using and couldn't be happier.
