Same answer as previously stated.........with my recent B+ grow, I bought EXTRA large bags of medium and let them sit 6 months- yup, just left them and forgot about them- then brought them out in the light 12 hours a day, around 73 degrees 24/7. Mine started pinning- I think it was 5-6 weeks for me. I know they do best at 75 degrees. Everyone gets different results- it's always different for me. Temps, humidity, temp and humidity fluctuations, grow style, kind of lighting, how much lighting, strain, karma- these all have an impact at each stage of mushrooming. It's hard to screw up this strain- it's so flexible. Time frames are often longer then expected but it just makes it all more worth it.
