Great stuff

My plants are so happy but believe the warning when they say wear gloves 🧤. It causes micro splinters that itch and hurt BAD and are impossible to see

Great 4 Drainage, Odor Control, and Healthier Root

This horticultural charcoal is a must-have for anyone who keeps houseplants or terrariums. The pieces are a good size (not dusty), rinse clean easily, and mix well into soil without breaking down too fast. I use it in my indoor plant mixes and as a drainage layer, and it really helps prevent soggy soil and root rot. It noticeably improves airflow in pots, helps control odors, and keeps the soil fresher for longer. My plants seem happier overall—especially moisture-sensitive ones. A little goes a long way, and the bag size is perfect for multiple projects. Highly recommend for indoor plants, terrariums, and anyone making their own soil mixes. I'll definitely keep this stocked in my plant supplies.

works

I use this in all of my custom soil mixes, for a drainage layer at the bottom of my outdoors container pots, and for making charcoal vents in my larger pots. It's even a nice amendment in raised flowerbeds. It is extremely messy. Wear gloves when using.
