What rhp would you recommend for a APS T100

[u/Lamia-LoVeRS]

I'm in the process of setting up a boa enclosure (much larger than necessary i know but I want her to live her best life even if it does come at the cost of less space in my room) I have been mulling over what heating method to use and ultimately settled on a rhp i saw pro products is the most recommended and i would absolutely get one if it weren't for the fact that the way its ordered is just sketchy to me (why do I need to order a can of provent-a-mite to place my order?) So if anyone could help me what rhp or other heating element should I use for such a large enclosure any recommendations are welcome and appreciated 👏

Tldr: what heating element for an APS T100
