As soon as they’re 100% or at least the exposed surface is completely white.. between 3-5 days after spawning
They’re cased with pasteurized jiffy mix @ ~1/2”... then once that’s about 90% colonized, they’re recased again between 1/4-1/2”. After that, the sub is patched by moving the uncolonized sections of jiffy over to the colonized parts with a gloved finger. When that’s fully colonized, it’s played by ear... some experimenting was done. Sometimes it was left after that to fruit and sometimes it was patched lightly/thinly in spots that became more colonized (you can even see in those two top bins up there that one was patched further than the other—left one was patched further). Not too much difference between the two. They’re pretty much in knotting stage by that point. I’d say about 2 weeks to get there.
As far as moisture content and misting of the casing layer goes, the jiffy mix is brought up to field capacity before pasteurization and after it’s applied, it’s misted fairly heavily (probably just before it looks muddy)... that’ll let the rest of layer of casing absorb some of the mudiness and put it back at field capacity as some moisture is lost during pasteurization.. that’ll carry the casing moisture for about 2-3 days. Then a light misting is required about once a day after that to keep the casing moist (especially on the side that sits against the LED lights)
Even though the LEDs are low heat, they do produce enough to slightly dry out that side... being that the tubs are rotated 180 degrees each day, the whole tub gets a light misting about once every other day (you can also tell by the color of the jiffy mix if it’s dry—a neat trick is to put a small amount of casing material between the two pieces of liner so that it doesn’t get misted or water dripping on it from condensation on the wall.. that way you can compare the dry jiffy to your casing on the surface of the sub since they’re right next to each other. If the sub’s casing is getting as light in color as your dry jiffy between the liner, mist those parts)... that continues up until about 1/2 way through fruiting.. at that point, the fruits themselves thwart drying from the lights.. those top two tubs will probably finish up in 3-4 days (about 21-23 days from spawning in average with the cultures she’s been working with)
Works every time. :)
I was taught that method for PE by another OMC member at another site, Tedsdead. It’s all about casing depth with PE and maintaining surface conditions and providing plenty of FAE.
