This is the first time I tried to grow mushrooms and I'm not sure if things are still on track as it going pretty slow and would appreciate someone having a look.

I needle biopsied some store bought button mushroom and made a liquid starter with dry malt. Then I made grain spawn with some chicken feed and finally it went into coco coir in small "shoe box" containers.

Can anyone see based on the attached photo if I am likely to get any mushrooms?

I have been working on this Vase Wing OpenSCAD project for a bit but Im still new to OpenSCAD and looking for some tips before I carry on.

My primary issue is that the Preview Pane is getting slow and it seems to be an issue for people especially on windows. Are there any OpenSCAD guru's on here willing to take a look and make some recommendations?

The project is on GitHub over here: https://github.com/Beachless/Vase-Wing
