Oh, those mysterious mushrooms! Sometimes a grow kit just doesn’t produce mushrooms in the timeline you expect, despite following the growing instructions. Each grow kit is an individual. Some are late bloomers who need a little more time, and some are quite particular about the humidity or temperature being just right for them. Mushrooms need extremely high humidity to form, and not enough is often the problem. If you have been trying for several weeks and your kit has not produced, try these steps that replicate the natural conditions – heavy rains combined with cold nights and warmer days – that trigger many mushrooms to fruit in the wild: Rehydrate it. Heavy rains are an important factor that trigger wild mushrooms to fruit. Completely submerge your kit in cold water for 2-4 hours (use a plate to weigh it down), and then drain off any excess water. Poke small holes in bottom if necessary to encourage draining, as water pooling in the bag can cause bacteria and mold to form. Give it a “cold shock”. Temperature fluctuations can also stimulate the fruiting of wild mushrooms. Think of pleasantly warm spring and fall days when the temperatures then drop to cold nights. To emulate this temperature fluctuation, place your kit in your refrigerator for a night or two Keep humid. High humidity is essential for mushroom formation, particularly tiny new mushrooms which are very susceptible to drying out. Place your kit under a clear plastic humidity tent with holes that allow for air exchange. Mist the inside walls of the tent several times daily, or more often if you find the water droplets evaporate completely off the walls of the tent. Alternatively you can create a simple fruiting chamber by putting a water vaporiser inside an aquarium or small greenhouse, and using a computer fan to bring in fresh air. Change the location. Some species of mushrooms prefer to fruit in cooler environments (like King and Blue Oysters),while others prefer a warmer environment (like Elm, Yellow and Pink Oyster). Try moving the kit to a cooler or warmer location. Don’t give up!  As long as your kit is white with fungal mycelium and has no patches of blue/green or black mold, it’s alive! If you are ready to give up, find a nice shady location outdoors where your kit will be exposed to rain, and leave it be. You’ll often get a pleasant surprise months later when it suddenly produces a bouquet of mushrooms after a heavy rainfall. If, in spite of following instructions, your kit doesn’t fruit, we are happy to replace it!
