 Vermiculite casings

Well some people were telling me that vermiculite casings work well, but I have found that vermiculite alone makes a very poor casing layer. I just got done recasing 2 vermiculite only casings with 50/50 casings because of exteremely poor performance (poor colonization). The casing layer simply refused to colonize well at all. I will never use a vermiculite casing layer again. Just wanted to share this experience.

I would love to, but the problem is that I don't really have the space to deal with it. Also I have to hide my growing from my 3 roommates. I was thinking about trying it over Christmas break that is if my roommates leave.

The hardest thing about doing a verm casing is keeping the water content right. Verm doesn' t change color much when it is dry, like 50/50 or coco coir does. If you can maintain proper water content, verm is a great casing.

I am relatively sure I maintained the proper water content. It just seemed to perform fairly poorly.

Verm constitutes what a casing layer should be, at least theoretically. It is a non-nutritious layer that can provide your mycelia with humidity and act as a barrier for contams while providing a fruiting surface. With that being said, you're right, it kinda sucks, I've found that 50/50+ works much better, but verm is fine if you can maintain water content.

I'm doing two casings of EQ in straight verm at the minute, and the first one is looking great, and looks like I will have a good pinset. I'm going to try and get some potting soil or oystershell for my next casings though. Can't get any horse poo until my broken leg gets better

New Name - I'm with you, vermiculite casings suck... You should try straight wet perlite, it's the best, better and cheaper than 50/50... I speculate that the people who are reporting great successes with straight vermiculite casings are not using #1 coarse grade vermiculite, but rather #2 or maybe even #3, the finer stuff. Casings need to be packed relatively flat and semi-tight, this ensures the best water absorbtion from the mycelia/fruits. You don't get this with #1 vermiculite, it's just too damn puffy and light. The finer grades tend to provide more ideal conditions... Even with that said, straight perlite kicks the sh*t outta verm or 50/50, imo

In reply to:

As a substrate, yes. For casing, NO.

using course verm as a casing layer does suck......what i usually do is put all my course verm into the blender and whip it up into much finer stuff, this colonizes great.

why is coarse verm bad. What qualifies as coarse verm not sure which kind I have. Not too big but not too smal about the size of tic tak.

INV: Exactly how much water do you add to your perlite and how thick are your layers? Do you sterilize your perlite, and if so, how do you go about doing this?
Thanks

every1 hates me for giving them the ole "searchy searchy faqy faqy" response. so to keep you all from hating me: try pouring about .5-1 gal of water in the bag of perlite and then cut slits in the bag and drain out the water and dump that in the tub. layers of what exactly? senseless to sterilize the 1st round because you ARE going to use h202 or bleach water AREN'T you? as far as sterilizing afterwards, well you can soak in bleach water or bake in the oven. guess what? all these questions have been answered a jillion times and could be answered with a simple search or :gasp: reading the FAQ.
edit: while I am not changing this post I am adding that my browser displayed this as the opening post and therefore I thought it was TIMMAY's posted question and not a reply. anyway, the info still stands.

i find straight vermiculite brought to near field capacity, and used as a casing layer in a MONOTUB works great. Due to the constantly high rH inside of a monotub. Coir being added , for me anyway, is a basic way to tell when it needs moisture, because the coir goes from dark blackish in color, to a red hair looking color, once i realised coir was basically a moisture indicator, while still slightly nutritious, i switched to JUST verm, and only in a monotub, because it keeps perfectly moist

One benefit to straight verm. is it hardly overlays; because it has no nutrient for the mycelia to want to colonize it. Unfortunately that means poor colonization; unlike 50/50.
