Expanding spawn is easy, it's usually refered to as grain to grain. Take one of your colonized bags & add portions to fresh bags & mix well. I'd probably go with about a 6 or 7 times expansion. I hope you have a contaminant free environment to work in. I don't have a flow box to work in front of right now so I'm running a HEPA filter air cleaner in my "office" for a few hours before working with anything.
Good luck

Well I went ahead and transferred a few teaspoons of culture to another new bag... and away it grows!

--cultured1, I used only maybe a 20th by volume comparison so I spose it will take longer to fully culture.

I don't have a HEPA filter but have other ways to clean the air. How much does it cost to set up a flow hood?

And good news!! the council cut down some birch trees nearby so I have 5 new logs each about 80 cm long to age then inoculate. The bad news is I think they have to be cultivated on soil and I live in a flat!

Anyway, the future is looking better and better. But does anyone have any advice to pass on about how to manage oyster mushrooms for the fruiting stage? Do I need a thermometer? is temperature critical? I have a hygrometer and accurate scales to measure the change in mass from moisture loss.

Any help is appreciated
Thanks again folx,

You can buy premade laminar flow boxes but they can get expensive. I'm thinking about making one using a storage bin for a frame, HEPA filter element, 2nd bin for an air intake & an old fan from a microwave. I've seen posts with links to plans, I'll try & find it.

A covered plant stand may work for a fruiting chamber, check out the gallery, I've posted a pic of what I used to fruit a shitake block last year.
As allways, good luck with your grow.

Its funny that of 4 culutures of this fungus on coffee grounds, 2 have boomed, yet the other 2 are lagging behingd. Could it be variations in coffee brand? Moisture content? There are no contaminants visible.

Does it need perhaps some added vitamins in water?

I am enjoying this hobby but haven't grown a single mushroom so far!!!
