Mosser Lee Horticultural Charcoal Soil Amendment for Plants, Terrariums, and Indoor Gardens, 2.25 dry quart

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.

I have recently started collecting plants and it really helps to add this to the soil mixture when repotting. Charcoal helps with excess moisture and balancing the pH levels. So far all my plants are thriving.
