Problem with my Oysters growing on cardboard

Hi all !
I've been trying to grow oysters on cardboard for a few months. Got a bag from fungi perfecti and inoculated jars of cardboard soaked in water. I previsouly pseudo-sterilized them by soaking them in hot water for ~1hour. However I'm not very careful with keeping things sterile.
Anyways the mycelium took over the cardboard pretty fast. Then i started to get some mini-oysters. But invariably, and that's happened in 15+ jars several times each, once the caps are 1mm to max 1cm, the mushrooms dry up and die. No matter how much I spray them.
I've tried the following: - Bring them in a warmer room - Put the jars horizontally so that CO2 would not accumulate. - Increase the temperature of the room
Any idea ? I now inoculated with wood chips to see whether substrate is the issue but it's gonna take a while. Could it be a lack of proper sterilization ? When they die, after a few days they get covered with mold, but more oysters keep coming out in the same jar anyway.
I attach some pictures. I want to eat my cardboard ! Thanks a lot ! Yannick

Have you been trying to fruit them next to your heater? Maybe your cardboard sub. is to dry.
Are you using only cardboard in those jars?
It seems like cardboard always takes a long time to colonize for me, so yours may have dried out a lot since you inoculated them.
You could try soaking a couple jars, draining them off really well and re-fruiting.
Or try a layer of pasteurized casing soil at a healthy field capacity. It could do wonders.

your cardboard looks really dry, i'd do what poofter said. you need an environment with 85-95% humidity to fruit them in. like a shotgun fruit chamber or something....
also, next time just put these in a 5 gal bucket or a plastic bag, so its not so hard to remove when the mycelium consolidates and gets hard. you don't have to "pseudo-sterilize", just pasteurize at 140-160 for 1 hour (not boiling).
good luck!
