casing layer question
#26417272 - 01/05/20 10:06 AM (4 years, 24 days ago) |

its been a long time since i have been on here (the shroomery) and it looks like casing layers are not as popular as they used to be. i always did 10 or 18 gallon totes with pasteurized horse poo, and of course a casing layer. if i ever get back to it, a casing layer isn't necessary? And not many people was using coir for a sub, not having to pasteurize coir makes it a lot easier. thanks

Yeah most people just do about a 1/3 inch layer of coir on top in place of an actual casing. Unless it’s pe.

No its not necessary but it can help. The reason being is it helps maintain surface moisture. This helped me before I had a better idea on regulating moisture. I'm only on my second successful bulk grow so not enough experience for thorough advice. Seen plenty of success without it.

I feel a casing leads to contamination issues. I never use one unless its required.

Casing doesn't lead to contamination..
-------------------- But if you're in a hurry, and really got to go If you're in a hurry, might have to find out slow That it's one thing to try and another to fly You get there quicker just a step at a time It's one thing to bark, another to bite The show ain't over till you pack up at night

Yeah he says a lot of random stuff.
Why would you feel it leads to contams? Just personal experience?

Only thing that I could think that would support this is adding a casing in combination with over misting / having it at an above ideal field capacity. Excess of moisture is usually one of the bigger contributors to contams. Then again that's more dependent on the quality of your spawn Edit:

The only issue I had with casing was the very first grow I did. The tek said to sterilize the peat which actually makes it more vulnerable to contamination.
Besides that it’s whatever I mostly do top layers.
Although most of my best pin sets have been with casings.

Longer colonization times. Ive used straight verm with no issue. It's always been coir that ive had contaminate.If i dont case I can get 4 or 5 flushes off of my Monos so its not in my sterilization. I also used the same brand of coir in both the sub and casing. I used an uncased dub as a control(which fruited faster and more abundantly).

 Spawn quality is not an issue with me. Do you think that if peat contaminates quicker because of sterilazion that the coir could do the same through pasteurization?

From what I understand peat needs to be pasteurized also. I guess it has its own microbiome that keeps it clean so if you sterilize it everything dies and then it’s wide open for whatever happens to land on it.
I think it’s the same deal with coir. Although my last handful of shoeboxes I just used hot water in a bucket to make the coir and Cased with jiffy 5050 mix right from the bag with no problems.
Definitely not the best practice but now that I’ve got the basics down I keep trying different things to see what’s absolutely necessary and where I can cut corners if needed.

Everyone says coir cant contaminate but it did out of 3/9 tubs. The other two were 3 no casing and 3 verm casing. All of them were a straight coir sub prepared at the same time. It had to be the coir that contaminated. Green spored mold.

I think some types of coir come with trich in them because it helps plants too. As long as it’s pet store coir it should be ok though.
What do you use instead of coir?

I got a bunch of coir at Wal-Mart. It was like 3 or 4 of those reptile bricks. They had it on sale for $2.50 when the off season started. Was labelled expandable soil. Nothing else other than the casings tammed out. I used this exact same brand for the substrate in all the tubs and other grows since with no contamination issues. I feel its because the coir doesnt completely colonize. All casing contamination came after the first time i opened the tubs for cropping. I have since stopped using a casing because i concluded from my results that coir casings contaminate and I dont like eating verm from a straight verm casing.

Casings work great...if the right materials are used and are prepared properly. I use peat based casings with a high ph, and pasteurize. Zero issues...providing that the grain spawn used to inoculate the substrate is not contaminated.
Although casings are not always nessecary, they are a nice tool to have in the tool box. Like any tool, you need to know how to use it properly, or it will act as a deficit to your project instead of an asset.

Do you have alot of flushes with that high ph casing? Stamets says in The Mushroom Cultivator "an overly acidic or alkaline casing mixture depresses mycelial growth and supports competitors".
