What are you using to heat the tank? Do you have an UTH under there? And what are you using to measure the temps? Also, you'll hear several time that ideally you would want a hide on both sides so your BP doesn't choose between thermoregulating and feeling secure. You'd also probably want to cover 3 or those 4 side with posterboard or something to make your BP feel more secure.
im from the philippines and its quite hot in here due to tropical climate. thats why other python owners here have their enclosure as a screen type cages.
i think temp problem arises mainly on foreign countries like USA, europe and other cold places.
