Thermostat question

Im thinking of a Vivarium Electronics VE-300 thermostat. will this work for one rack with 6 tubs? IDK much about thermostats. The sight im looking to buy it from says it can be stacked on one another, thats why i was asking if i need more than one for my rack.

It should be fine, if all of the tubs have the same amount of heat source, and you want all tubs to be about the same temp, 1 thermostat will be fine. You will have to do some experimenting to find the proper location to secure the probe, (I usually put mine on the heat, and adjust the thermostat until I get proper temps. in the tub. You may have to have the thermostat set at 100 to get the tub where you want it) once you are satisfied, fasten it securely with tape or silicone.

In a word yes.
as long as all the heat sources are the same it can also run multiple racks.

Thanks for the helpful information. im excited to build my first rack and see how it goes.
