why do you think my spawn run failed?

I had 2 12 qt sweater boxes fail to colonize completely. They sat for almost 3 weeks and barely got to 50-60%. I have some experience and think it could have been a couple of things - but not sure.
1. used clear tubs - so while they were in the dark a lot, they were not isolated from light. 2. perhaps too little spawn. Used 2 qts rye spawned to however much filled the 12 qt box full except for an inch or so headroom... I've used 3 qts in the past with better results, but my math still thinks 2 qts is a 1:4 ratio what with the headroom...maybe 1:5 3. Coir too dry? Is this possible? I hydrated in the bucket with 180 degree water... squeezed coir hard to get rid of excess water - too wet has failed me in the past. (I'm no longer going to do the lazy pasteurization method: I'm gonna do water baths in ziploc bags to pasteurize at 150F my substrate AFTER bringing to field capacity.)
All smells good so I don't beleave its contaminated. The 2 tubs look like cookies and cream if that gives you an idea. I'm going to attempt to fruit in a greenhouse to see if it will flush. Any experience with this? They are colonized enough to where I can get them out of the tubs and onto the lids - going to try them as giant cakes that way I can get the sides to pin, since the tubs were clear.
Thanks!

actually the same thing happened to me and I said screw it with the one batch and fruited and it fruited fine, I'm not going to let them sit in the greenhouse to long I don't need contams from not fully colonized sub
This method for your coir what do you plan to do exactly my one batch I think messed up was due to bad field capacity and I did do it the same way as you let me know thanks

Don't squeeze the water out next time. Add the right amount.

I've found some light squeezing to be good. Full hydration hinders colonization too much.

because you touch yourself!
when i used coir (only used it once) i added verm cause it said to in the tek i used....my coir was pretty gross, looked like mud, very wet....i added the verm to make it 50/50 and it soaked up all the water to the perfect texture, i didnt lose water and only added a little bit of volume. verm soaks up water like a sponge and ANYTHING colonizes on verm.

When using straight coir... Hydrate coir with boiling water, let cool covered by foil, squeeze lightly so only droplets come out from the coir. Works like a charm. You can always add more moisture by dunking before fruiting.

You failed to pasteurize. I'd say that's the most likely scenario. In addition, I'd suggest a heavier spawn ratio next time.
Pasteurize after hydrating to field capacity by heating the middle of the substrate to 140F to 160F and maintain that temperature for one hour. RR

I checked my temps in the middle and they were over 140, so I put the lid to the buckets on - it may have not been long enough at this temperature to past though...
yeah I'm changing my methods to the way you do in your DVD there RR. I did it the other night with large freezer ziploc bags, cause all my jars were in use. It worked well and no squeezing - time will tell. and I did use 3 qts instead.
With my last batch though, it seems like the myc never really recovered - no one mentioned the fact that my tubs were clear (I did get a few side pins that I forgot to mention). Is this not the reason for the stall?

Clear tubs make little difference. First, light is not a pinning trigger until after full colonization. Prior to that, it has no effect. RR

yeah that was what I thought as well, but I've also read where you said preventing light was important in bulk - but you may have been referring to after the casing layer is applied - if you want it to colonize some...
I think it was a combination of low spawn ratio and bad pasteurization methods. If you say it was because I failed to pasteurize - does that mean contaminants stopped the mycelium from spreading? And does this mean it is bascially a contaminated bulk? cause all smells and looks healthy - just under colonized...
thanks for the help here RR
