How should I modify the 50/50+ so that I don't need Lime?
    #5365380 - 03/04/06 06:29 PM (17 years, 10 months ago)

I have plenty of vermiculite, peatmoss, and crushed oyster shell, but no hydrated lime. How should I alter the ratios to accomidated that best?

Here's the mix

Quote:


* 15 1/2 cups vermiculite
* 15 1/2 cups peat moss
* 4 1/2 cups crushed oyster shell
* 1.2 cups of hydrated lime
* 15 cups of distilled water (1 cup short of a gallon of bottled water) 16 cups = 1 gallon

substitute coir for the peat
and no lime is needed

I have Coco Coir so I was thinking maybe doing:

50% - Vermiculite
20% - Peat Moss
13% - Crushed Oyster Shell
17% - Coco Coir

I indented the middle two because they're dependent on each other.

I've heard greaat stuff about 50/50+ so I want to retain it as much as possible, so maybe a mix like I posted above?

So you think it would help to throw in some peat moss with extra cruchshed oyster shell to make up for the lime?

I've got it anyways. Otherwise I would just be doing the 60/40.

since you have no lime
the less peat you use, the better.

I guess I'll just save the oyster shell and peat for some later date and just do 60/40.

Perhaps I've read it wrong but.. Ground oyster shell IS to balance the ph. It replaces lime. If you have finely ground oyster shell, I'd just use that.

If the oyster shell is ground to a fine powder then it will act fast enough to balance the pH of the peat.

How I make my mix
Fill up bucket with water and dunk your peat into it. This makes it easy to remove sticks, stones and break up the chunks of peat. Once I've just got some nice looking peat I add 5% oyster shell powder. Then I add a bit of oyster shell that is slightly courser. This acts as a very long term buffer. ( I let my tubs go for many flushes, like 7 or 8 because they are low maintenance.)

I then add an equal amount of verm.

Last I expand some coir and add that at about a 10-20% ratio.

Microwave pasturization.

I've got a good amount of finely ground (powdery), but no course shell. A 5% shell sounds kinda low considering youre also taking out the lime..

It's been working for me I can say that. I have never had a casing contaminate. I have always been able to get multiple flushes ( More then 3 before mushroom production has really slowed) and my pin sets have never been a disappointment to me, Granted I would like to see my pinsets improve to something more like wall to wall but considering I am using multi-spore inoculations of B+ I would probably move to an isolation before I would worry about improper casing mix pH.

If you use a higher percentage you will still probably be fine. It's my understanding that calcium carbonate is pretty fool proof. This is because it wont react until in the presence of acid. So once your mix is neutralized the extra calcium carb will remain as is until acidic enzymes are released by the mycelium.

The addition of gypsum is also recommended at the rate of five to ten percent.
