Your girl wont gain weight at all if she doesnt have proper temps, As for hydrofarm, Again i suggest agasint it, this is for plants... nor animals! they can be off by a few degrees, and dont have nearly the safety features as a Vivarium electronics/Herpstat by spyder robotics! For roughly double the price you are getting 1000000x quality thermostat! unless you need right away, yes use hydrofarm as temp but i wouldnt suggest using as a main one!
