You could use coir as mentioned above and that may work better.

If you have vermiculite and are all set for that route. Roll the wet cake in dry verm, let it set for an hour or 2 then mist it. If you already right away you'll just rinse it off.

Same basic procedure with coir. Rehydrate is with as little water as possible. Wet cake dry Coir, let it set for a bit, then mist.

You could hydrate a brick of coir and use that instead.

The part that really gets me about rolling it in vermiculite. Is the vermiculite is supposed to be dry.

With coir I just got that out of a bucket that was filled with boiling water. So I feel like it’s clean.

With the vermiculite, I just have to hope. That’s why I just don’t want to use it for rolling my cakes anymore.

I got the old bag of verb from Fred Meyer and I was pretty convinced it was dirty beforehand. It’s just so dusty.

It’s probably sitting around for a while.
Cooking up a brick, I don’t have to worry about it.

I stopped using the dry verb layer, and I stopped having contamination problems.

It is possible. But I cut that out and things have improved dramatically.

well, I suppose a non nutritive medium could still act as a transport vector. Mold spores could perhaps, catch ride on dry verm. Only germinating after nutes+water are introduced (where the dry and wet layers contact). Dunno, just thinking out loud.

Vermiculite has been used for 35+ years. Why would adding boiling water to coir make it clean?

---

Because. Hot water, Tao.  Duh! /s

Yeah I was dead set on verm but coir may be the right choice here. It's so hard to decide. I think coir is optimal and I can get it to field capacity easy enough I just hope I don't overmist for surface conditions.

In my mind at least it's probably the same difficulty figuring out if I've misted enough.


I may just use verm for a few and the rest coir. So many choices

You can do whatever you want. Mix Coir and verm and do 1 like that. You might be the first person to do that?

Cour may be the better option. PF was developed back in the late 70's or early 80's. I don't think Coir was as popular or common then. Vermiculite works as a contam barrier in the jar and holds moisture so it was likely used to limit the amount of items needed as well.

Hard to over most on pf cakes as they have such small horizontal surface area. You could dump a glass of water on it and it's mostly going to run off.

If you see big drops or puddles you overdid it. If you see little beads of water don't do anything.

If you see neither most a little.

Definitely not the first.

How best do you code your plates when working with multiple strains and plate transfers?

TheAtlantean said:

The real question is why are you misting in the first place? If you are doing cakes, I guess soaking the Verm through misting might be an option but the cake should have enough moisture to start pinning and create a microclimate good enough to form primordia.
