Bulk Vermiculite/Brown rice flour
    #23173049 - 04/30/16 02:55 PM (8 years, 8 months ago)

I was wondering if anyone has tried to do bulk grows with the PF tech type of substrate.
Verm/BrownRiceFlour mix with dry verm on top.
I was thinking about doing this because the materials are readily available for me.
I would sterilize the bulk in a aluminum tray with foil over top.
Then inoculate the substrate with syringe. Let it colonize then put in my Ultrasonic terrarium.
Is this a good idea or is it better for me to just switch to grain bulk spawning.
thanks.

Don't do that man, it's a waste of time. If you have a pressure cooker, sterilize grains and spawn to poo, coir, or poo/coir. If you don't have a pressure cooker you could do a bunch of half-pint jars the pf tek way, when they are ready crumble them up and spawn to bulk.

The pf tek doesn't work on a huge scale for one good reason, its will become bacterial over time which will bring colonization to a screeching halt.

Stick to the teks and your gold

Are these big trays? Why trays for pf tek? No jars available?

I do have jars but i want to gain as much surface area as possible with maximal yields.
That is solid advice on sterilizing the jars first then moving to trays.

Try it man, just do some jars with it. And make sure the trays are not too big and make sure the verm barrier doesn't shift around under the foil.

You could even inoculate through the foil after you swab it with alcohol and flame your needle.

Also are these trays see through? U want to look for contams as it grows.

Another thing, I would use plastic trays that say PP 5 on the bottom. This means they are pressure cookable.

I love these

surface area is not directly relative to yield mycelium will produce as much or little fruit as it can, no matter how much surface area it has.

you cant use BRF as bulk substrate for the simple fact that it will contaminate really easily.

BRF works in jars, because you can colinise it in a sealed with only gas exchange.

If you sterilise it in trays, once you open it up to spawn your colinsed cakes to, its contaminated and molds and bacteria will outgrow the myc.

You can spwan your cakes to bulk substrate, you jsut have to break up your cakes and use them as you would grain.

ive used cakes broken up in a blender to spwan to Hpoo or coir, works great.


If your taking about sterilising pftek mixture in a bulk sub sized container, good luck fitting that in a pressure cooker.

spwan your cakes to bulk sub, or just move to grains. grains are really easy.

I don't think that is accurate. Look at these threads.

Just PC the BRF cakes in jars. I use quart ones.

Well i mean the cakes are individual circles. If i could have a large flat cake with the same vertical girth wouldn't it spawn more flushes?

bulk substrate produces more fruits because it has different nutrients, not because it has more surface area

ah so PF Tech cakes by themselves will always produce less than coir/poo bulk sub?

It depends on a lot of things. To many things to list. the simple answer is do what works for you.

bulk will not always produce more, regardless, but it is generally considered to be the way to get the best bang for your buck.
