Started a 3lb bag on October 17. Injected it with liquid spores. I followed all of the instructions, and everything has come along on track, on time: the mycelium growth was fast and smooth. Now, 40 days later, the shrooms are pinning. Today I'll slit the bag at the top to oxygenate the fruiting. Will also give the bag 12 hours a day of light from a grow lamp. Now, Day 46, I have a near-full first flush. The grow lamp, along with maintaining proper room temperature, has been key for expediting this first flush. A BIG Loud Applause: I'm giving a standing ovation to Mushroom Supplies (a Five Star rating) for their excellent customer service. They always get back to me within a day, answering my questions. And their product is top-shelf––I just purchased two 5lb bags. Exciting for a first-time "shroom farmer".
