Coarse Vs. Medium Grade Vermiculite: Big Difference!

Question

18 answers to this question

Interested in the results of your mix.

Mine wasn't labeled but it is similar to the course that you showed.

Understanding the overall volume of the jar stays the same, if the medium holds more water it stands to reason an orifice (haha) filled with medium verm will contain more water and less air, therefore less CO2 than using course.

See where I'm going?

This is true, but I'm really not sure where you're going with it.  Yes, it stands to reason that the medium has more surface space to hold water than the coarse does.  Two cups of verm is two cups of verm regardless, but the coarse has more air space.

 

Using this logic, it seems that medium grade would be ideal for substrate as it holds more water, while coarse is ideal for casing to allow for more co2 at the surface.  IDK right now, it's one in the morning and my brain is slowing down.  I'll think about it more tomorrow :P

I have mixed the two....I'll share my experience.

When I mixed the two for wbs jars...well...I can't say for sure that it was the verm's fault but I've never lost that many jars at once. VERY few actually colonized. I believed the problem to be moisture level related. I could be wrong about the cause but that was the only time I ever mixed the verm for wbs jars and that was the biggest failure I've experienced to date. Out of 50+ jars, I think only like 5 or so made it...and that was working with an lc that I know was good and tam free. (But I was still very green with this hobby, so perhaps i fucked something up as well...)

As for mixing it in the sub...I didn't seem to notice much of a difference in how the mushies grew.

Most people don't.  That was the point of my post, to enlighten.  :D

 

You may have your best luck at Ace Hardware.  You'll have to ask someone to get it out of the back stock room.

That is exactly what I have to do.

Excellent write up Professor Austiclees! What other classes are you teaching this semester so I can get registered?

I guess that I'll be monitoring this like my "Bird Dust" topic.  We'll see which one colonizes faster and which one puts out the best results.  That medium grade verm can really hold a high level of water content.  We'll check back in a few days and see where they are at.

 

After thought:

I really wish I had a third jar to spare so I could have done a combination of the two, (half med and half coarse) to put along side these, but I spawned a mono tub this morning with the other jars. Oh well.  Maybe when I have another fully colonized jar, I'll add it into the mix.

      Got my PE today thanks!

      First time working with a swab based innoculation vector, Agar and LC are not options atm, are they any methods i could use besides making a single Grain jar then doing G2G?

      All that stuff can be found in the salt water fish section. You would have to read what is used in the ph adjust kit.

      U should definitely not have any snakes calling over ur sub. I once read that diatonicmaceous earth would scratch reptiles belly plates & cause them to dehydrate. That's what it said.lol   Sent from my SAMSUNG-SM-G900A using Tapatalk

      Read my teks. None of them use gypsum at all. Then look at the results. I'm positive I can grow many species of mushrooms. Not just cubes. It can definitely be skipped! Although you do need to adjust pH with most bulk substrates. You can use gypsum to adjust pH, I just prefer using calcium hydroxide for that since it instantly adjusts pH. Gypsum is a pH buffer meaning it helps keep pH stable, but this is not effective against mycelium, as mycelium does excrete acidic enzymes as it decomposes the substrate. But because it is a buffer it doesn't really increase pH as much as calcium hydroxide will. It more so just keeps it steady in dirt.
