BRF Tek Grow - Oysters And Elm, Oysters Don't Look Great...

Hi,
Had a go at a BRF Tek grow recently and did some Oysters and Elms (Hypsizygus Ulmarius). I took a spore print from some old oysters I had grown and made a syringe which I used for this grow. I bought the Elm spore syringe from an online shop.
Anyway the Elm's seem to look okay (maybe a bit old now though) and the oysters look quite deformed (caps haven't really opened up properly) and although they were dark blue to begin with they seem to have turned to a light brown colour now.

It has taken me weeks to get them to grow, as well. Probably about 3 weeks. I was expecting it to take only a few days. Humidity was around 95% and I misted at least 3 times per day, and fanned them too. Any idea why the oysters have turned out like they have? I'm guessing still not enough air or not enough light.
Thanks for any advice.

Small caps and elongated stems are generally caused CO2 buildup, low light and warm fruiting temperatures. Blue oysters will become grayish as they grow, but they also require a lot of light to keep that color.
The elongated stems are less of an issue with H. ulmarius than with your blue oysters. Elm oyster stems seem to be a lot softer than Pleurotus species. I like to let them get really big before harvesting.
In any case, your yields are going to be lousy using BRF cakes! They would be better if you substituted sawdust for vermiculite, but you'll get much better results if you crumbled your cakes and spawned them to a bulk substrate.

Thanks a lot Paresthesia. I kind of wondered how good the BRF Tek would be but thought I'd like to give it a go anyway.
I've got another 10 jars that are fully colonised at the moment. So do you suggest that I simply use these jars the same as I would use a grain spawn? (Simply crumble the cake into some straw?).
Another thing I was wondering... if I used a spore syringe that I made myself (collected spores from a previous grow) and then injected this into my jars... would this not have such a good yield as there would be so many strains competing? Or does it not affect it? Also if I made a spore syringe and injected it into a jar full of grain would this be a good way of making spawn? Or would the differing strains/higher risk of introducing contaminants make it a not very good idea?
Thanks again.

Yes, use them simply like you would grain spawn
It shouldn't affect it if the spores are all from the same species
Yes, That would be a fine way of doing spawn, but isolating is better, although NOT necessary at all
Oysters eat most contams for Eggs and Bakey, and I THINK that Hypsizygus will do the same, but you shouldn't have a problem. Even with alot of regular species that aren't oysters it should work, but we'll see what others say.. It's some button mushrooms that really bite trying to germinate.
You knew everything already!

It looks like you were growing at room temperature and oysters prefer cooler temps. Consider edibles on BRF to be for educational purposes only, and not for food production. You can easily grow your spawn on brf cakes, but for food production, you'll want to spawn them to a bulk substrate material. Oysters like lots of bright light, cool temps, and unlimited fresh air supply. RR

I've got either Ostreatus or Pulmonarius, whichever the grocery stores sell here. I've only seen the one kind in stores.
How cool will they keep growing ?
Can I grow them in the fridge ?
What's optimum ?
THanks in advance.

Ostreatus prefers cooler temps than pulmonarius. i grow my oysters at 25 deg C. I have heard of growers using pulmonarius in Jamaica.
