Things are pretty slow outside this time of year, so it's the perfect time for an indoor growing project. And look what finally arrived!
I did one of these last year. It was a lot of fun, and I got two good crops of mushrooms. But I didn't read the directions well and I messed up after the second crop. This time I'm paying better attention, and I'm sharing the adventure here.
Several companies sell these ready-to-grow kits. This one came from
Park Seed.
The day the box arrives, unpack it. For this kit, the box contains the block of impregnated growing medium, drip tray, plastic bowl that elevates the block off the tray, a vented plastic bag, and instructions.
The plastic bag is used to make a tent that helps hold in the humidity. In addition to this, the block needs to be misted with water daily (that's part of what I screwed up last time).
The first step is to soak the block. This time the block was still damp from shipping (which is why you need to unpack immediately - even a day or two and it would have been the right environment for the wrong type of fungi to proliferate). But the block needs to be saturated with water to help jump start the mushroom growth.
While I was waiting for the horses to finish their dinner I set to work on soaking the block in my wash rack area. A bucket, some cold water, and I'm almost ready to go. I say almost because the block is very light weight (usually its compressed shavings or chopped straw - very buoyant). It needs to be weighted down so that the block is completely submerged. This way it soaks up water evenly throughout. The instructions recommend filling a gallon milk jug half-full with water and using that as the weight. However, this block was really big, and really buoyant, so I filled up the jug all the way so it provided enough weight.
The instructions said to soak for a few hours, but I let it go overnight. Last time I ran into problems with subsequent soaks, so I'm hoping by making it super saturated this time I can stave off those issues.
In the meantime, the cardboard shipping box needs to be prepped. The box comes preprinted with lines indicating where to make the cuts. Just be careful to not cut yourself.
This morning it was time to remove the block from the soaking bucket and assemble the growing module. The instructions say to put it in an area out of direct sunlight and with temperatures in the range of 55-65 degrees Fahrenheit. Since I keep my thermostat at 65 in winter, and the kitchen is always cooler than the rest of the house, the kitchen table is the ideal spot.
It's a little early to expect some mushroom growth, but give it a day or two. Now, if you'll excuse me, I need to mist my block.
