Some great replies everyone! I think I understand what is going on a little better. Terpenes and THC are extracted with solvent, and jars facilitate crystal growth with various external techniques. The byproduct, which is actually the primary product, that I was asking about are the THC-a crystals that formed with the full spectrum terp rich sauce being the actual leftovers? And thus, the sauce can be in many different concentration forms depending on how much or little of THC was actually converted to THC-a? In the snowball down hill analogy, I assume that snow on the hill is the THC in the solvent and the snowball is the THC-a crystals?
