Lightweight Pumice – Volcanic Soil Amendment for Superior Drainage & Moisture Retention
Pumice (filtered to 3/8″–1/4″) is a lightweight volcanic rock prized for its porous structure. When added to potting mixes or used as a top dressing, it enhances aeration, regulates moisture, and supports healthier root systems—perfect for cacti, succulents, bonsai, and all your favorite houseplants.
Key Features & Benefits
- Moisture Retention: Absorbs water and nutrients, then releases them gradually like tiny batteries, nourishing roots over time.
- Improved Drainage: Prevents waterlogging by allowing excess moisture to flow away quickly.
- Enhanced Aeration: Creates air pockets in soil for optimal oxygen flow and vigorous root development.
- Lightweight & Durable: Easy to handle, won’t compact or break down over time.
- Sustainable & Clean: Pre‑dried for convenience—no damp, dusty mess—and 100% natural, chemical‑free volcanic rock.
Why Use Pumice in Your Indoor Garden?
- Healthier Roots: Reduces risk of root rot with superior airflow and consistent moisture balance.
- Consistent Growth: Balances hydration levels to prevent stress from over‑ or under‑watering.
- Versatile Applications: Ideal for mixing into potting soil, top dressing, propagation medium, or bonsai substrates.
How to Incorporate Pumice
- Soil Amendment: Blend 10–30% pumice into your potting mix to improve structure and drainage.
- Top Dressing: Sprinkle 1–2 cm over soil surface to enhance evaporation control and deter pests.
- Propagation Medium: Use alone or combine with other substrates for rooting cuttings and seed starting.

Best itchy soap.
This is has done more for my itching than about anything else. I was skeptical at first because "what works on both eczema and psoriasis?" But this is very effective. The instructions say "let dry out on skin for intensive treatment". I would NEVER let any ordinary soap do that. But this treatment truly works.
It is excellent quality smells nice but scent is subtle and hypoallergenic. It is very emollient. Fair warning: you need to let it sit on your skin for a bit before you rinse it off. It kinda has to soak in before it rinses clean.
And that's the other thing: you feel clean after using it instead of having gunky residue. If you have humid summer skin rash it even helps with that itch. It's very protective of your skin.
If you want it to fit in a portable soap dish it fits a standard container if you cut it in half. It even does that well!

Amazing soap
This is the best soap I’ve ever used to help with my psoriasis and my son’s eczema. It completely helps calm down flare ups and clears it completely leaving our skin soft.

It works!
I can’t believe how well this soap works! It actually relieves the itching and irritation on my neck from eczema. It lathers well and it smells really pleasant without smelling too perfume like. I cut the bar in half so it would be easier to handle. I also appreciate that it is made here in the USA, and surprisingly, it doesn’t dry out my skin like most soaps do. I’m so glad I found this!

Seems to help, but who knows if you only shower 1x a week
Seems to help, not hurt. But I don't shower every other day, so who knows. I will say it melts quickly, way quickly. Might be worth it if you shower every day or so, to get the moisture benefits. For me, I'll just use super moisturizers with Shea butter instead.
