 Vermiculite Question 
#376423 - 08/22/01 12:57 PM (23 years, 3 months ago) |

Hello All,
I'm *trying* to grow my first crop and I think I may have already ran into a problem. The only vermic. I could find was the very course stuff. So, I used it anyway and I innoculated and I havn't noticed anything yet. Will the course vermic. work? Or should I just start over with the fine stuff? Any help would be greatly appreciated, thanks...
-C.

The coarse stuff is useless as a contam barrier, furthermore, it will screw up your substrates moisture. It can be made finer in a blender.

Ya, the verm I've bought doesn't say what type it is. Most of the chunks are like "Grape Nuts Cereal" sized. I assume this is the fine ground stuff cuz' I colonized ten 1pt. jars so far and no cotam's yet. Just did my first verm casing yesterday and doing another today. So far so good :^) !

My friend also bought verm. that didn't specify if it was coarse or fine... The size of most of the pieces were about as big as the seeds of an orange. I guess this is prett coarse. Anyways, at the time my friend didn't know, so she used this in her substrate and as a verm. seal. The jars took 6 weeks to fully colonize, which was probably due to the verm and the moisture being messed up? I don't know. Out of 8 jars, 1 got contaminated.

Wait a little longer. You may get some spores to germinate. In the future, you can just grind up your vermiculite to make the particles smaller.

Thanks everyone, for the responses. I checked the jars today and some of them are starting to germinate. There are a few jars, however, that just don't look right. I mean, before I even innoculated these ones, it looked like they were already white because of the brown rice flour. I think I may have added too much water to these (I did experement with different amounts of water in each jar). Any other feedback would be much appreciated, thanks...

When preparing the substrate, do it this way, this works with coarse and fine grade vermiculite.:
Put the required amount of vermiculite in a bowl(NOT for each jar separately!). Use a spatula or spoon to mix in enough water to make the vermiculite about as damp as it can be without feeling soggy, mix well. (A small puddle, very small, should form at the bottom of the bowl when tilting the bowl). Then add the appropriate amount of BRF and mix together. The idea is to coat the wet vermiculite particles with the dry powder as you stir the mix with the spatula. This sounds trivial but it makes all the difference.

Horticultural grade should average about 1 millimeter long. That's the stuff.

The vermiculite I use (with success) has a particle distribution from 2-6 mm.
