Casing Substrate 50/50+ calcium carbonate
    #2831597 - 06/26/04 09:14 PM (12 years, 5 months ago)

I have already posted this in the cultivation forum with nu useful replies, my guess is that they couldn't answer because of experience or soemthing so here it is for you advanced growers:

After a week of searching for vermiculite and coco coir in my city and having found only ignorant answers from the store employees I have decided to use the Peat Moss and Vermiculite 50/50 tek (because initially I had some verm, enough for one casing when I have two jars = 2 casings)... Now, I know the pH of the substrate has to be regulated with some calcium carbonate, which in all the teks is represented in the form of crushed oyster shells and lime. Now I know one acts as a slow acting PH buffering agent and the other one as an inmediate agent.
Do I also need sand if I still have not enough verm?
And for the last, if I can find pure calcium carbonate in a drug store in the form of pellets... what is the ratio I shall use in relation to the peat and verm? I mean this because obviously pure Calcium B will need less quantity than crushed oyster shell or lime (say if you use 25% total of shells+lime, should I use 25% of CACO3 then?...
Thanks in advance-.

Don't add sand...it has no moisture retention.

Your ratios are not something I could tell you as you are shooting for pH which will vary depending on the source of your peat moss. Someone here in the past measured the pH of the peat he was using and got varying values depending on the source.

Shells do release CaCO3 at a slower rate. Lime releases the CaCO3 pretty fast. If you have pure CaCO3 it will adjust your pH quite fast as well.

Your best bet is to find a pH meter or litmus paper and adjust your mix according to pH...which is the whole point anyway.

OK, so you pH differs between sources of peat moss. But lets say that unless I got an extremely acidic or alkaline peat moss I shouldn't worry about pH so much since I still have CaCO3 to buffer the pH...
I say this because it is difficult to get ANYTHING where I live, and what I can get has price inflation and all that crap so thats why I ask if I should risk it with the CaCO3... Anybody with experience can tell me what ratio shall I aproximately use for this mixture? And if I still need to use a slow acting buffering agent like crushed oyster shell? I hope I won't need it since I'm frustrated from not finding shit in this place, even the verm supplier has run out of it!

do you have a pet smart or a pet store in ur area????? coco coir is reptile bedding. it will usually come in a compressed brick. vermiculite is at lowes.

Thanks for the help but unfortunately I don't live in the states. I live in Chile and so, I have problems first because I can't find the right translation for coco coir, then, when I make the calls to pet stores and I ask by coco derived products, I get negative responses. About the verm, the only distributor in hardware stores and the like says that they have exhausted their supplies and don't know when they will have again...
Thanks anyways, its still useful because of the "reptile bedding" thing.

You could also use peat and perlite instead of vermiculite (50/50).
Oyster shells for PH buffering are easy to get.
If you cannot get calcium carbonate you might be able to get soda (Na2CO3).
It is used by housewives for washing their laundry.
Usually you can get it in normal supermarkets (at least here).
And adjust the PH to 7.5.
I have used that and it worked very well.
