New grower curious about casing.
    #26975068 - 10/08/20 08:13 AM (3 years, 3 months ago)

I've been reading a lot lately about the 50/50 casing method. I think I know what materials to use and how to pasteurize them. My main question is how do you set up your fruiting chamber with the casing material when you are ready to starting pinning the shrooms? Do you crumble the mycelium cakes and mix them with the casing? Does the casing layer go on the bottom of the bin which is then covered by moist pearlite? For my first grow I just used the classic pf tek method with cakes cased in vermiculite but I left them whole. My mushrooms seem to be growing small and I don't think they will produce very many mushrooms. I'm hoping that a nice casing with evenly distributed mycelium will produce a more bountiful flush with healthier mushrooms.

Crumble the cake with the substrate, mix it together, then make it flat. Once you do that you apply the casing layer on top. The casing should not be mixed with the spawn (BRF cakes).

Also casings probably won't make your fruits bigger. They really just help to maintain surface conditions for cubes at least (other species this is different)

What you’re referring to as casing is called Bulk substrate. The most common and easiest to use is coco coir. You want your bulk sub to hold as much water as possible while still remaining light and airy enough for mycelium to colonize.

So in bulk growing you’ve got your grain spawn (or BRF cakes as spawn if that’s what’s your doing) which provides the nutrition, and bulk sub that provides water and pinning surface. You mix the two evenly and then you put about 1/4” top layer of bulk sub on top to keep grains from drying out and provide a good microclimate for pins to form. The bulk sub provides its own humidity in the tub through evaporation.

A casing is a little different than the top layer I just mentioned but a lot of people use the terms interchangeably now. A true casing would be taking something like jiffy mix or making a peat based substrate that you would put on top of your sub around 80% colonization.

Damion5050 made the original bucket tek and has confused a lot of people into thinking to use a 50/50 mix of coir/verm.  I use 80/20ish

So where does the pearlite go? On top of the substrate or beneath it?

Forget about perlite when you're fruiting a bulk substrate. Post a pic of the surface conditions and only then will you be able to get reasonable advice on how to proceed.

Perlite is usually only used to supply humidity in your growing chamber..  Are you talking about adding a casing layer to your cakes(like a double end kinda thing) or crumbling your cakes and applying a casing layer to make a tub?

Best advice.  At first I thought this was a 17 year old thread someone had bumped.  But it was 17 hours, whoa.

Hang around mush cult and read threads for like 30 days and you'll learn a lot more than from those 20 year old posted "teks".

I like late casings, Using cvg as a bulk. Then approx 10 days into fruit/spawn hit it with 1/4 ' jiffy mix casing. Especially in the summertime. Just helps keep surface conditions optimal.

I'm trying to crumble my cakes into a substrate to make a fruiting chamber. I was under the impression that pearlite is necessary to maintain humidity even if you use this method. Some pics I've seen show mushrooms growing straight out of a layer of pearlite which I assumed was covering the casing layer underneath.

The 50/50 casing is a good casing tek to learn, but you probably don't need to make a casing at all (unless you're growing Penis Envy)

What you are thinking of is "bulk substrate". That's what you mix with your shredded up cakes. The most popular substrate nowadays is coco coir

Casing is something that goes on top and it's not really necessary in most circumstances if you're growing cubensis

^Those two threads are all that you should need to do BRF cakes in monos

Forget about casing for now. Forget about Perlite if you plan to shred up the cakes
