### ⭐⭐⭐⭐⭐ Excellent Results
*by J***N on November 12, 2022*

I am very happy with the grain spawn I received. I used it to inoculate a 1 quart grain spawn jar (white wheat and gypsum hydrated with tap water). I had significant mycelial growth in less than 48 hours. I also put a couple mycelium covered berries on agar and had visible clean growth in 24 hours. I’m very pleased and highly recommend.
