no vermiculite techs
    #6802830 - 04/18/07 03:49 AM (16 years, 9 months ago)

Well, finaly i got over the problem of not having enough vermiculite! I discovered AAC or Aerated Autoclaved Concrete. The rest is history! No vermiculite is needed any more. I just let chunks of AAC sit in water for a couple of hours and then I pour out excess water and add brown rice flour, mix it and nuke it in a microwave for some time. That's it! I have a great new tech, without vermiculite.

In order to find a substitute for vermiculite (it's hard to find around here) I used styrofoam cut in small pieces and got good results, but such a cake needs to be watered from time to time using sterile water, but if you're really desperate, it works.

1 World, 1 Mycelium!

Well, they're colonizing right now, I'll think about that when the time comes. I think I'll use AAC as the moist base on the bottom, and I'll use sterile sand on top, to stop contaminats. It worked before. Right now, it's just a PF style cake, boldly going where no other has ever been before :smile:

What is the price of this AAC? Is it cheaper than verm?

Well there isn't much to photograph. But I'll post a few pics. First of all, this is a block of AAC, people also call it gas concrete. It is white, easy to break int pieces, and the most notable thing - it is not as heavy as you would expect it to be.

As for the price... well if you find a vendor, it will probably sell it by the packs of several blocks... which is about all the AAC you'll need for a lifetime of shrooming. It is often dicarded in chunks around building areas, construction yars, etc. I got mine from a house rubble left over after a NATO airstrike. Anyway, you break it down into pieces of about 1cm in diameter or less, like this.

I found a hammer to be too destructive, it turns it into powder. Use your hands, it is quite easy to fragment. Once you have the desired amount, let it sit in water for a few hours (2 is generaly enough), to soak. Shake it lightly from time to time, to remove the bubbles. Unlike vermiculite, it soaks slowly, but also keeps water longer. Pour out the water, and keep the wet AAC.

Then, eyeball the amount of brown rice flour, just like in PF tech. Mix it with wet AAC, and sterilize anyway you like. I nuked mine in the microwave for only 2 minutes, but it depends on the amount. Its always better to make several smaller cakes than one large.

After that, let it cool, and inoculate. I inoculated mine with a fragment of agar culture, but spores work aswell, and so does the les notorious "mushroom water". That's it. Here's where I'm at now, you can see the mycelium, the small white spot. Cute.

That's about it. Generaly it is a PF tech, only the adsorbent is different and takes more time to soak. What was I to do, I couldn't find any cheap vermiculite anywhere in my country.

Sorry about the size of those pics BTW...

And as for the styrofoam tech... well I'm not really proud of it. It does work, yes, but it takes more effort. Styrofoam is hydrophobic and must be watered often and that increases the risk of infection, yatee, yatee...

Maybe it is best to forget it, and wait for somebody else to rediscover it.

:crazy: yeah, sorry.. I had trouble finding the right word so I used the one I found first. So, breeze blocks it is! AAC sounds wierd anyway.

I think they're two different things. Breeze block is a term used in the UK for concrete masonry units - like cinderblocks in the US. Aerated autoclaved concrete is different. No big deal just fyi.

Well, that's a problem, see. I won't start a new cake anytime soon, before I'm sure that this one works. Maybe sometime later I'll make a pictorial, but right now, all we can do is observe the results... I'll keep you posted, right now, the mycelium is progresig quite fine and promising.

So all we gotta do is wait for a NATO airstrike, sweet. Just kidding. Hope that wasn't in your own neighborhood.

Hehehe only good thing about NATO airstrikes is that they are so damn accurate. It was less than a kilometer away. And the building went down in 1999. No one cared about the rubble... until now! :smirk:

Hi everyone, it's me again! Just wanted to give some remarks about the long term use of AAC (aerated autoclaved concrete). I've been using it for about three months now, and I've made some adaptations to the tech. Here goes:

Again, break the AAC into small pieces, about 0,5-1cm (0.25-0.5inch) in diameter, make enough to fill the future container for mycelial growth (a jar or whatever, I use 0,3L polypropylene disposable party glasses). Anyway, let it soak overnight in enough water to cover it all, and add 50ml of 3% hydrogen peroxide, and mix. After all of this sits overnight and the concrete is soaked, pour out excess water. Mix this with BRF or whatever it is that you'll use as food. Pack into jars or glasses, and continue with the sterilization as usual.

Notes: I found some sorts of integral biscuits to be just as good as the brown rice flour. Also, rye flour is cool.

Don't know anything else about this method, but don't use rye if you don't have a pressure cooker. Rye flour != BRf.

Wheat grains = endospores. They will fuck up your grow to no end. Otherwise, enjoy the tek, though I have no idea what he's talking about (as most laymen have no idea what vermiculite is).

Just a warning for steamer-reliant newbies.

How is the speed of colonization versus a vermiculite/BRF cake?
