Big Foot Mycorrhizae Granular | 50g (Cass of 30)

Pre-Measured Biochar & Kelp Soil Packets for Single-Plant Use, 50g (Case of 30)

Some growers want a dry soil amendment they can sprinkle or mix directly into the planting hole rather than dissolve in water first. Big Foot Mycorrhizae Granular combines biochar, worm castings, kelp, azomite, and humic acid into a dry blend that mixes easily into soil at planting or transplanting.

Sold as a case of 30 individual 50g packets, this size is sized for single-plant application at transplanting, one packet per plant.
