Newb after a suggestion about non pinning

[dubster]

Hey guys

I've done quite a lot of reading and watching vids trying to get my first grow right.

Had full innoculation on my cakes after about 3 weeks.
Gave them an overnight dunk and then rolled in vermiculite.

Now into a fruiting chamber, lined with moistened kitchen towel, which is kept at 70 (with the lid on, if I take the lid off for constant breathing my heater will only keep it at about 63), which I open up, spray cakes, walls and lid and waft 3 times a day.
The box is kept just inside the doorway of a darkened room, but indirect sunlight can get to the side of the box.

Almost 3 weeks into fruiting now and no pinning happening.

So was after some suggestions as to what I might be missing.

I'm thinking maybe

1) a new heater is needed to keep it in the 70s with the lid partially opened.
2) an automatic vivarium mister type thing.

Anything else anyone can suggest I might be getting wrong?

Thanks so much everyone.

Sounds like you are doing everything right. Perhaps you got a strain which is difficult to get fruiting?
