Peat in container mix

[hiker_]

My neighbor gave me some "container mix" which I used to pot up my tomato seedlings. They seem to like it, so I figured I'd make some more of her recipe for the determinates I'm planning to keep in containers.

It is:

2 5 gal buckets sphagnum peat
1 5 gal bucket perlite
1 5 gal bucket vermiculite
1 cup dolomitic lime

Has anyone used this kind of container mix with good results?

And...

The mix she gave me was already mixed. And moistened.

I now have a bale of not at all moistened peat.

She's talking about making layers of peat, water, peat, pile heavy stuff on top of it, etc., etc....

Someone else tells me nah, just soak the *vermiculite* before mixing everything and the peat will get moistened from that (but would that throw off the peat measurement?)...

So I thought I'd ask here. Anyone who uses peat in container mix, how do you moisten it?

When following a mix recipe with peat, how do you measure it (before or after moistening it and does that make a difference to your measurements)?
