I remember the one i took was light green. I did alot of research on the subject befor consuming too and never found that information. This is the exact reason i asked the question instead of searching the other threads. Thanks mate!
Yeah I only figured it out after trial and error, and then found some others talk about it at some point long after. From what I understand, the darker the better, and when you age it in darkness it gets even darker. I have aged light green/fast growing stuff(it seems that speed of growth is what makes it weak and light green) and it didn't change it much - not into anything usable anyway. Aging it in darkness stresses it and makes it produce more of the mescaline/other chemicals that make you trip.
