mushroom fruiting chamber

hi everyone

I have 2 shiitake grow bags coming and am going to make my own fruiting chamber

1. starting with a clear 50 liter storage tub
2. drill holes 5cm (2") grid around sides  5cm (2") from bottom of tub
3. fill bottom with wet perlite
4. put bags on bricks to keep them above perlite
5. going to open tub once or twice a day and mist and fan it

how can I keep humidity up ?

am I missing anything?

thanks heaps
Shane

Hi Shane,

Your setup is fairly standard, so I'm not sure if anything additional is required to keep humidity up. Just make sure you have 4'' or so of perlite on the bottom. If you live in an arid place like I do, you can spray the substrate 3-5 times a day, but make sure it doesn't get water logged as that's worse than being a little dry.

Alternatively if you are feeling up for a project:



I've never needed one as I do bulk grows, but they seem practical. Good luck :)

Good photo Jarret, quite similar to what I was going to mention.
A cold humidifier does wonders for being able to keep humidity in the sweet zone since they are adjustable for how much humidity you put into the air.

thanks heaps guys we are just coming in to autumm here so it will start getting colder as shiitakes like it cooler it should be good
I was worried bout humidity cause it will cool and I thought you need warmth to produce humidity
