Soil Sunrise Horticultural Charcoal for Indoor Plants (4 Quarts) Hardwood Soil Additive for Orchids, Terrariums, and Gardening

Big enough for the larger plants but can also break into smaller pieces. Great for controlling bacteria growth and good amount for the price.

I will from here on out use this for my isopod and bioactive substrates. It's a bit too small for springtail colonies but is perfect for any ABG mixture, isopod substrate, and most bioactive substrates. It's perfectly thin instead of chunks, but not too thin, and mixes well through out the substrate so it really helps with the soil health.

Good stuff

Got this as a way to keep fungus gnats from the soil in my houseplants. Works like a charm and looks nice to boot

Prompt delivery. The content amount was appropriate for what I needed. The size of some charcoal particles was small and became a bit messy during setup of my planters.

Nice package, perfect for my small plants.

This is an absolute need for growing healthy houseplants! My plants look very healthy and great after mixing charcoal in with my soil mixture. It provides plenty of benefits, like providing aeration, soil fertility, and preventing root rot! It's a definite yes.

No complaints! Exactly what I was looking for and made a great addition to my substrate potting mix. Good drainage
