Since I figured growing techniques would be popular, I thought I'd share my fruiting chamber here. This is actually the last step in the process of growing, but at the moment, this is the only chamber where there's anything interesting going on.
This is a $30 indoor growhouse I bought on Amazon (I bought 2 of them, actually. The other one is my colonization chamber.) It can be seen here:
Psilocybe Cubensis mushrooms like to fruit at around 72F-76F degrees, so I have the outside temperature of the room set to 72. The chamber inside is a few degrees warmer.
I cut a hole near the top and ran the hose of a humidifier through the top. I have it set on a regulator, so it kicks on whenever the relative humidity in the chamber falls below 75% (Psilocybe Cubensis prefers relative humidity of 85-90% when fruiting.) I also spray the cakes with a fine water mist at the beginning of each morning. This should be done until you begin to see primordia, which is the beginning of mushroom pinning (I'll post a picture of that once I have a mushroom cake showing primordia.)
I open up the chamber and fan in the interior 4 - 5 times a day, to allow for fresh oxygen to interact with the mushroom mycelium. Mushrooms engage in respiration like humans, in that they absorb oxygen, and release carbon dioxide as waste.
In the above photo are two small tubs of Golden Teacher. They've been in fruiting since this past Saturday. Its hard to tell from this view, but if you enlarge the photo, you van see that this mycelium is super healthy, and is rife with rhizomorphic growth. Rhizomorphic growth is indicated by the mycelium growing in an almost strand-like pattern, looking like tree roots running through the substrate.
In the above photo are two tubs of Koh Samui Super Strain (KSSS.) As you can tell from the photo, the mycelium in these tubs is a little more tomentose, or fluffy, than the tubs of GT. There are still some rhizomorphs growing, but they're not as plentiful. This strain has given me some difficulty. KSSS is supposed to be contaminant-resistant, but most of the tubs I've attempted with this strain have all gotten contaminated, except for one. These two look solid thus far, so fingers crossed.
These are bags of Lion's Mane mushrooms I've also put in the fruiting chamber. Lion's Mane is a gourmet mushroom (non-hallucinogenic,) but has been reported to have many medicinal properties, especially when taken when one is microdosing psilocybin (google "The Stamets Stack," named for Paul Stamets, the world famous mycologist.)
These should all bear fruit within the next 2 weeks or so (probably sooner.) I'll share photos once all is said and done.
