Great vivarium construction method. From creator: I used heated pvc pipes with prolypropylene rope. I covered it with a compaktuna(/flevopol)-and peat-mixture using a paintbrush. I covered the pipes and rope twice with the compaktuna-peat mixture (mix compaktuna with water and peat) 1 part water, 1 part compaktuna and 2 - 3 parts of peat. afterwards I covered the uncovered parts by hand with brown sealant (soudal - Fix All) and sprinkle with peat.
