Not enough outlets/tstat

So I have a 7 slot rack system and a pre-wired 6 slot Johnsons Controls thermostat. I haven't filled the rack just yet but is there anyway I can add more slots? Can I add another power surge strip to the existing wired one? If so, would it matter what kind?

I don't see why not. I doubt it will exceed the wattage limits of the thermostat, so you should be good...

You will be fine! I have my 9 slot rack connected to my Herpstat which only gives me 3 slots to work with. I have two power strips connected to the Herpstat. As long as you don't exceed the maximum wattage of the thermostat, you're fine! :)
