12 quart bulk trays, weighing 12 lbs each average at spawning.
Identical substrate, spawn rate, tray volume, covering, gas exchange, and incubation.
Trays that appeared to colonize very quickly at first, seemed to have slowed down.
The trays that started slower, than those above, gained speed, caught up to and passed the quicker starting ones.
The slowest of the group is extremely healthy looking. It is just taking it's sweet slow motion time. 
Out of an identical group of 10 trays.
7 were fully colonized, and cased about 48 hours ago. Today, the casing surface on 6 of the 7 have visible myc appearing. I plan a light patch application tomorrow.
Of the 3 uncased trays, today 2 appear 99% colonized.
Then, lagging behind by 15 or so %, is the slow Motion one.
I have never seen this much variation in so near identical trays.
I wonder if the difference could be the multispore syringe, inoculation to LC, into the wbs Spawn. Is it possible, the genetics differ that much from spawn jar to jar?
At this staggered pace. It appears in 2 or 3 more days. I will strip the coverings off 7 trays, and begin 12/12 light cycles, high Rh, and FAE in the fruiting chamber.
The 3 remaining trays will be moved to a separate smaller incubator. Then, as applicable cased, re-incubated, and when the casing cover is colonized, moved into the larger fruiting chamber, with the 7 others.
Strange goings on here. 
Oh well, all are progressing, none contaminated. Tippin's on the home stretch 
I just love peeking into cased trays, and seeing myc cropping out.
There should be a song to sing, when that happens.
I plan to pour my first 10 Pyrex perti's tomorrow. I will probably bungle my virgin batch. Oh well, learning from your mistakes is part of the game.
I want to give this isolation thing a whirl, and see what results.
I also figured out what the strange looking contraption, on my guys work bench is. I did not want to ask him, because I feel silly when he tells me what things are, as if it is obvious to anyone. 
At first glance, I thought it was some kind of water heater plumbing. On closer inspection today. I realized, it is an AA 941 lid, with 1 of the 2 toggle valves removed. And, in its place, is a valve, and fitting that about 15 or 20 feet of 1/4 inch copper coil extends from.
On the far end of the copper coil, is a large rubber single hole plug. Under the work bench is a 5 gallon beer/wine brewing type glass carboy. I checked, and the plug on the coil end fits into it perfectly.
From all this I gather my guy uses an AA 941 sterilizer, to sterilize, and distill water supplied pre-filtered from 6 stage 100 gpd R/O filter system next to the bench.
In the grocery stores, distilled water is about $1.50 a gallon. So, why would he go to the trouble, to make his own. 
After some thinking about it, I realized that the store bought jugs of distilled water, while in fact distilled, are most likely not really sterile, or even close.
I would assume the jugs are filled by some sort of bottling machine, in a plant, none of which is sterile. And, even though new, and clean, the jugs themselves are not actually sterile either.
So, my perception of distilled water at WalMart has changed. I always thought of it as sterile, when in fact is is far from it.

Perhaps the line from the PC is to use it and the other barrel to steam pasteurize straw?
It's completely normal for different trays, especially with multispore inoculation(sperm-egg parallel??) to move at different rates. After all, they're living creatures. What litter of puppies, kittens, or for that matter, humanoid offspring from the same genetic stock always grows at the same exact rate? RR
