oh buddy I am so happy you topped that BB. That is going to be such a nice plant!! I got about 5 flushes from 2- 5lb grow bags. then mold and bacteria got them and it smelled like death, very traumatic experience. If you ever see mold chuck them and dont mess around!! I think I pulled just over 4 oz dried from my two bags, I grew B+ and PES Hawaiian. almost identical strains, i really didnt know what I was doing at the time. I inocculated the bags with 10cc syringes on the first week of july and it was the last week of AUG when they started pinning up all over. I advise you to put light on the whole block of substrate, not just the top, and let the whole thing pin up all over. Then transfer it to a fruiting chamber and the ENTIRE brick will be covered with big meaty shrooms. I prefer to make tea from the fresh ones, its the best experience i've ever had. I should have some pics from my grow somewhere around here, let me find them for ya. I had those two blocks taking turns in the fruiting chamber for about 2 months, getting a harvest almost every friday from the rotation. It won me a lot of popularity amongst local mycologists! I had kids practically beating my door down for them. It was great money and I made some new friends! barely any effort too. I made some spore prints that i'm still hanging onto, and recently filled a double lined garbage bag with substrate, got it to colonize, and right after i placed it in cups to grow, and placed them in the chamber, some fungus flies showed up and everything turned yellow and pink and molded over. real sad day, but just remember to make prints from your best caps
