Good question @bluelightbandit!
It's not the strains themselves that require the decarbing but the mix of cannabinoids that each of the strains contain. We currently have identified 111. Some share the same decarb temperatures and time and others require different temperatures and different times for closer precision...and you know how my mind works...I happen to really appreciate precision. For the love of anything good, do it right or don't bother getting out of bed. LOL!
