why hate on 100% vermiculite casings

I have always used 100% verm and never had a problem with it.. it is a non nutritious casing layer that holds moisture very well... if you prepare it right... which is what a casing layer is supposed to be...
then why does everyone want to use coir and peat and all that, when they contain nutes, and can be more easily contam'd than pure verm, and tends to get overlay alot easier than pure verm...
I am not switching cause I get killer results with straight verm, but why does everyone run their mouth about pure verm casings, especially by those who have never tried it?

Peat does not contain nutes, and it is what commercial growers use.
Maybe because of the more earthlike texture?

It's easier to judge the moisture content of a casing layer that contains peat compared to vermiculite alone. Peat/coir also gives the casing layer more of an airy texture.

Well I am not super experienced with casing materials but I'm sure out of all the people who have tried different ones have seen results that prove that vermiculite isn't the BEST...but most will admit that it can work.

Some people just use whats at hand, I dont have any trouble gettin anything for growing, anything you can think of I can find local. Depends on what part of the world your in I suppose.
If you have good grows with just verm and your happy with it, then more power to ya.

yeah.. I mean.. my setup uses a 24 7 cool mist in a big ass tub, and I wet my casings before I case by soaking it in water and letting it drain good, then just a small quarter inch layer of the casing over my substrate.. get good solid flushes and seem to never run out of moisture during a flush.. just mist lightly till pins form, and leave it be... then I dunk, drain, and set it back in...
I just never knew why people used that stuff... I guess it couldnt hurt to try a small cased culture of 5050 or something..
I know alot of cats say dont leave a cool mist on in a tub for 24 7 with perlite because its too much moisture, but mine works fine.. I just have alot of holes all around the tub and I can cover and uncover holes as needed to change the humidity, while still getting 24 hours of fresh air and keeping the RH where it needs to be... maybe the way I have my tubs set up is why I get such good flushes with the verm casing...;)

Peat contains beneficial bacteria. These bacteria result in increased primordia formation and higher yields. Verm otoh does not contain these bacteria but holds water better than peat (verm = 5.0 ml/gram, peat = 2.5 ml/gram). 50/50+ is a casing that's great for species such as cubes. But commercial growers use peat because the edible species they grow fruit at lower temps iow water holding properties are less important.

Nebula is right, straight verm may work well, but 50/59+ works better.
But hey, if you like your results with verm, then why change.
More power to you brother!

Peat contains beneficial bacteria that is a pinning trigger...Vermiculite does not
Vermiculite is NOT contaminant resistance...smaller flushes with straight vermiculite...bigger flushes with 50/50 peat moss/vermiculite.

Sure about this? Anyway, peat casings are not contaminant resistance. Peat casings can be hit by green mold, that's why you need to pasteurize peat containing casings. I find it hard to believe that verm can be contaminated considering its material. Also, Paul Staments (http://en.wikipedia.org/wiki/Paul_Stamets) describes his casing formula "1 part peat, 1 part water crystals" as a formula containing "NO contaminant supporting ingredients".
