    grain preparation can be a bit of ball-ache when you're trying to make a lot with a relatively small sized autoclave. This is the first time I've bought this in bulk, but for the price, it's not really worth me making it myself any more. That's capitalism for you (or maybe just scales of economy). Either way, I'm happy. Grains were perfectly hydrated, no standing water and mycelium is growing as expected. Mushroom cultivation has just got even easier…

    Perfect for the lazy mushroom head!

    On a more serious note, grains came well packaged and perfectly hydrated.

    I initially thought the grains were dry, so I contacted their support team who clarified that they weren't dry, but that they had been soaked and boiled in water containing gypsum, and when they are allowed to steam dry, there can be a fine residue white powder on the outside of the grain which can make it look dry. Paul from support said that I should try them, and if I wasn't happy he'd either send me a batch with no gypsum added or a refund! Needless to say, the grains were perfect, and I learnt something! Thanks for your support Paul. Have a nice rest of the day.

    Correctly hydrated and good quality but I think it's a little bit expensive for hydrated grain. Maybe if you're ordering in bulk or buying other supplies it makes sense but I just needed some grain as my pressure cooker packed in last week

    I don't really ever buy pre-hydrated and sterilised grain as grow on quite a small scale but I wanted to conduct side-by-side grow trials of various grains and measure colonisation times and resulting yields of each. Seemed like a no brainer. Haven't found any other company offering this, so thumbs up to you for doing so! I'm sure there are others out there who appreciate it as much as me. Leep up the good work!
