i watched a snakebytes video on world of ball pythons.com just yesterday. the show was on substrates and what they like to use at BHB. Brian never gave the brand name that they use nor can you clearly see it on the bag but im 99% sure it was JOLLY GARDENER. It is double processed so the pieces are smaller and 100% cypress. im going to switch from shredded aspen to this as soon as i can find it local. i'll most likely pre treat it with PAM just to be safe.
