The only thing I've changed this past run. 2 weeks in, the most rapid mycelium gross I've seen yet. Haven't fruited yet. Hoping for a massive harvest. Fingers crossed.

Huge Difference

After using this with grain spawn and substrate, I can definitely say it made a huge difference in colonization rate! Highly recommend this over regular gypsum.

Wonderful product and great delivery time.
