Best substrates for changing temp

[Black_Inky_Eyes]

So when I get my hamster I will be using Hugro Hemp as my bedding and probably mixing that in with a little bit of Megazorb. This is so I can have some Megazorb and Hugro left over for spot cleans.

However, by the time my hamster is due for a clean out the temperature will be significantly warmer and just go up afterwards. Is this substrate mix ok for hot temperatures in hamster cages? Keep in mind my cage is the glass Detolf so will naturally be warm a lot.

If not, have any recommendations?
