When conditions are right, your kit will produce a cluster of overlapping oyster mushrooms with broad caps.  Fresh Air Exchange One of the most common issues is “leggy” oyster mushrooms with long stems and small caps. This is caused by a build-up of CO2 produced by the fungus, and at extremely high levels will cause oyster mushrooms to look like a branching coral or white octopus. If your mushrooms already look a bit strange, it’s probably too late to fix it for this crop. Harvest and enjoy, then plan to provide more fresh air exchange while growing your second crop.  You can increase air exchange by poking more air holes in your humidity tent, propping up the tent bottom, or providing a fan. To compensate for bringing in more dry air, you will also need to mist more to maintain the high humidity. It’s ok to mist a little directly onto the oyster mushrooms, as well as the inside walls of the humidity tent. Some people use a tray of perlite under the tent, or a reptile fogger to increase humidity. Baby “Pins” Stop Growing Sometimes a cluster of mushrooms start to grow, but some or all of them “abort mission”. It is common if conditions aren’t perfect for some “baby mushrooms” within a cluster to abort while the others grow to maturity. Remove the stunted mushrooms when you harvest your mature cluster as they will not continue to grow.  If all the mushrooms stop growing, and they appear slightly dry with some browning on the edges, this indicates that they need consistently higher humidity. By contrast, if they look a little mushy and shrivelled, it may be the result of bacterial contamination that gets hold when too much water pools on the mushrooms. In that case avoid watering so much directly onto the mushrooms. Remove all aborted mushrooms, tweak the growing environment, and wait for the next crop to emerge. Pale Colour The colour of your oyster mushroom may not be as expected. Their colour (and texture) varies under different environmental conditions. When fruited in cold conditions, oysters tend to have a deeper hue and have a thicker flesh, whereas they can be thinner fleshed and pale to white when grown in warmer environment. Humidity and light levels also impact the colour of the mushrooms.
