Hi all,
I have no camera, so I have no pics at the moment. I just wanted to set everyone up with a write-up and then I'll bump the thread with the pics later on.
---
About a year ago, I ordered four spore syringes from Ralphsters. I was unable to use them until later. So once I could, I tested each syringe on PF jars. The only one that remained viable was my PESA. Once the PESA jar grew out and fruited, I made a clone by cutting tissue from the best looking
fruit and plopping it into an LC.
---
The LC grew out and I inocculated two test jars, and then twelve more. Fourteen half-pint PF jars in all. These grew out and I spawned them to coir, straw, one filter's worth of used coffee grounds, and about a cup of calcium carbonate. The ratio was about 4:1 straw to coir. Colonization of the substrate took about a week.
---
The substrate was pasteurized with 165 degree tap water plus a splash of bleach for 90 minutes in a big pot, plus the time it took to bring the water to temperature. The fruiting chamber is a rubbermaid tub, which is about 18" by 12" on the bottom. The substrate is about 2" deep.
---
After the substrate grew out, I pasteurized quite a bit of coir along with a cup and a half of calcium carbonate. I'm not sure how much coir, but I cased with 3/4" and had enough to case another tub of the same size left over.
(side note: I also spawned one PF cake after one flush to some of this casing mix in a Country Crock butter tub and gave it to a close friend as an early Christmas present. I'll include pics of this when I can for fun :) )
---
As for my rubbermaid, just before the substrate was cased, I punched 1/4" holes in the sides, every two inches, just above the substrate, for airflow a la monotub. Since the holes are so small, and it was hard to get polyfil into them, I'm going to forego polyfil unless humidity gets low. Also I cut out a section of the lid and taped plastic wrap over it for light exposure. This idea came from furry moderator Llamabox, from this thread: http://mycotopia.net...ghlight=monotub
Now, just so I don't leave you unsatisfied, here's some mycoporn from my last tub grow, a few years ago:

If I get results such as this I will be more than happy; this crop weighed in at about four ounces dry. Wish me luck! No need to reply to this thread, I will bump it when I have something to show you!

Just so it's on record, I put polyfil in the holes to help keep up humidity.

Sorry, folks, I was too busy to borrow a camera for pictures. BUT I have about 500 wet grams on my first flush! Yayah!

Now, I felt it could have been more: I definitely did not pre-soak my straw, and I didn't use dookie like I wanted to.

I'll try to get some harvest pics, and second flush, too. Peace!

No, no real overlay. I introduced fruiting conditions as soon as I cased, and also didn't water as much at first to keep it under control. It worked out fairly well. The pinset was really good, too, but more would've grown to maturity if I'd picked a couple of early-risers.

The second flush is coming. Quite sparse; only a dozen or so mushrooms making up the bulk, and then some johnny-come-latelies that will finish a couple of days behind. Like you once said, Hippie, straw tends to blow it's whole wad in the first flush. I might be able to get ahold of a camera, but there's not much to see. I'm not complaining; mushrooms are mushrooms!

In about a week, I'm gonna make a new tub using Mycrotopia Brand Donkey Doo!!!
