Perlite-bed TEK

#1757339 - 07/28/03 07:50 PM (21 years, 1 month ago)

OK. I haven't checked the Bulletin Boards for a while, and just don't get along with the search utility, and I haven't read all the growing guides either, so I don't know, if I'm gonna write about something new, or not. Anyway, here's my report on a casing TEK that I use and found very simple and very effective.

I grow the micelium in narrow-neck Jars, on whole-grain wheat. 2 dl wheat + 1.5 dl tap-water, pressure-cooked for one hour. Little holes on top, taped paper cloth on the holes as filter. The top is closed during pressure-cooking. I usually inoculate using living bodies: just a 1 mm thick stripe thrown onto the wheat through the hole: practically no danger of contamination this way. Cloning, that is. Full colonization in 1 month or less. Depending on room temperature. I keep them in dark. The substrate can be made as dry as just enough for full colonization, thus reducing the danger of contamination.

But that's not the point. I have a plastic tray, 8 cm deep, with a translucent cupola as cover, 25 cm in diameter. (Sorry for all this metric...) I make an under-bedding of wet perlite (I use 1% H2O2). A couple of centimeters perlite in the bottom, and around the perimeter. I push it down tight to get a hard perlite surface. I put the colonized wheat into this cavity. I just dig it out from the jar, and crumble it nearly to single grains, still no post-casing contamination problems ever (we love you, hydrogen peroxide). I put some loosely crumbled wet perlite on the top of the micelized substrate (what's the term?), just enough not too see any wheat. Vermiculite would be better, I suppose, for extra humidification is not an issue here. (I'm not sure about that, though). I keep the cupola on, make sure that perlite is always wet ( I use 0.5 % peroxide). I put a straw into the perlit near the edge, so I can check the bottom water level with a needle and syringe. I lift the cupola daily, or more often, dependingon my level of curiosity and impatience.

Here's a typical average harvesting log on 2 dl wheat (dry volume), psilocybe cubensis:

Pinning in one week. Second week: 70 g; third week 120 g; fourth week: 120 g; fifth week: 90 g. Wet weight all. I have little data on sixth week harvests: it's somewhere around 50-60 grams.

I hope, I haven't left out anything crucial during this description...

Comments and questions welcome.

That's a lot of water, indeed. That was my main motivation to try this way, actually. The H2O2 provides extra oxigen, and kills bacteria. The micelium can take much water this way.
What do my harvesting result tell about this technique? I dont really have any data to compare with.

interesting. no organic matter exept the mycelium. no contams. what the hell, I'll give it a go. I'll let you know if the trich in this part of the world likes it or not.
