    Hello Guys,

    I´m about to finish my first batch of mushrooms after three flushes. I have read that the used substrate can be used as fertelized so I think I want to use it to start a home garden. Do you Know if I need to do some kind of procedure to the subtrate for this or should I just mix it with the soil I already have? Is there suggested ratio subtrate/soil? any other use for it?

    Thank you,..

    Hi Diana,

    Great to hear you’ve had 3 flushes from your bags already. Could you email us some photos when you have a moment? It’d be great to see!

    The spent substrate is best if broken up and left to compost a little for a few weeks first, as you will find it will reform and grow tiny mushrooms if just used straight away from the grow bags. It will likely be slightly acidic (around pH5), so you may want t omix in some lime to make more neutral, depending on what plants you want to grow. It’d be best to mix it with other compost material, as the small structure of the coffee grounds means it tends to compact very easily if used on it’s own.

    Best of luck!

    Adam
