what is the benefit to casing cubes?

Recommended Posts

Tanelorn

Following mush zombies 6qt dub tub tek, it says it is not optional to case the tub. Ive read elsewhere that cubes need no casing, and i would like to address this now. I dont mind casing at all (though itll just be fine grade verm and shredded coir), but what exactly will it do for the mushrooms?

 

Also because i dont want to clutter up the board, i used some lc to noc a jar for testing and nothing grew. Could this have been due to the refrigerated temperature of the mycellium at the time of innoculation? I also suspect that the culture was stalled. Stalled doesnt mean dead does it?

Casing cubes let’s you get the evaporation needed for a good pinset, without drying out your substrate. Fine grade verm is not good for casing, coarse grade is much better

it's all i have and all i'm likely to get. either i use it or i dont. unless there is an alternative to verm that i can use. i've checked everywhere and all we have here is fine grade.

Without a humidity monitor, how can i predict what the rh will be? Should always be around 100 since i will mist and fan 3 or more times a day right?

100% relative humidity is impossible considering that means there would be no air, just water. I'd suggest learning what RH is and what it means first, before worrying about any of that.

Cheap digital hygrometers are also inaccurate over 60% RH. You need a good analog hygrometer for cigars to even get close to measuring 85% RH accurately. Otherwise be prepared to spend $400 bucks.

Just follow the Tek. That's the easiest route.

Like i said, not possible. Its out of season, and the many local stores ive been to either dont sell it or only have fine grade. I cant follow the tek if its not possible for me to do so. I wouldn't have made the thread if i didnt run into a problem following the tek.

Yeah ive been looking around online, its 16 bucks shipping and 40 bucks for the bag. Ill keep looking though. The main concern is that i already took the tub out and put it into fruiting conditions, so i was needing a solution yesterday. I'll just be extra dilligent about keeping it hydrated.

Best way to do that would be to take the sub out of the 6qt and put it in a tub with no holes and put perlite in the bottom (make a cake style fruiting chamber).

Thats a brilliant idea, im going to do this now. Also, is this contamination? It looks like cobweb to me. Shrinks up and disappears when water touches it.

Also, why no holes? Typically ive seen perlite used with sgfc. I assume holes are not required since i'll be misting and fanning?

Near the top left looks like mold not cobweb. Sub doesn't look well colonized.

Maybe i took it out too early. Not getting any weird smells though. Here is another picture. Should i put it back into incubation?

Do you have a Menards store near you? If so then you can get this 3 cubic foot bag of vermiculite for about $17. Check their shipping cost if you don't have a store near you. This is vermiculite is perfect size in my opinion. It's not fine, it's not coarse, it's more like a perfect medium.

Using vermiculite alone is not ideal. There are teks for 50/50+ casing layer. The Let's Grow Mushrooms video shows how to make this casing layer too. There are two basic recipes. More often I use recipe #1 because it's easier. Both work fine. It's about sourcing materials.

1. Uses 10-parts Peat Moss, 10-parts vermiculite and 1-part calcium carbonate.

2. Uses 10-parts Peat Moss, 10-parts vermiculite, 1-part hydrated lime and 1-part gypsum.

This 50/50+ recipe is all I've ever used and it works great. Source your materials now and stock up. Depending on where you live, materials get really scarce when fall/winter hits.

      Title Kinda states it all, Have multiple strains Knocked up By MS, bad weather destroyed all my cultures so i am restarting.  Should all be ready to go in 2 and 3 weeks.  Using WBS and Rye grains to look at differences in times and potency, takein the golden teacher to Agar as too the MS syringe is tamed. 66qt tubs,  not much more to be said at the moment either than, this will be a large grow and will start posting pictures of progress for educational purposes  when my master jars are about to be G2G. i have 16 master jars and plan setting them all to 10 jars (160 Qts of spawn). lets see if we can get pans to run strong in a mono, thats really all i care about, spore prints of the cubes will be available for trade or just for fun , Pans are up in the air as to experimental on my part  Ask questions ill answer to the best of my ablity if your curious, until then, you wont here back from me happy trails

      coming from someone who builds homes  for a living.... that will DESTROY that room in a few months, black mold everywhere etc.....love the fact that you have a GH room, thats dope but, unless you have (please dont take offense to this) a more professional build on This "GH room", you will end up destroying that room. i have though of building a shed for this purpose many time...unfortunately i do not own my own home yet

      Haha I 'm pretty sure I learned that from reading your posts about it. It's really a great way to do it, so thanks for the pro tip!

      Thank you.I didn't think this seemed right.time bulk casing I use comes from non-sponsor vendor, sms it seems really good.this Will bye muy first dedicated monotub grow- I've only done cakes so far. Dip,a little feast sms a lot of questions seem to be right in line.it seems maybe the person telling me this isn't real grower material? I've never seem any results from him, and I guess I can see why. I appreciate all your input, and I'm really grateful for your time.thank you so much.
