Gerta 10QT Horticultural Vermiculite Bulk, Organic Vermiculite for Plants, Course Grade Vermiculite for Gardening, for houseplants, for Mushrooms, to Maintain Soil Moisture and Plant Growth(2-4mm)

Appears to be fairly pure, no stones or sticks found. But it’s very fine. I ordered the 2-4 mm but it is pretty much all 2 mm. Nothing coarser. It’s perfectly serviceable but if I had known it was all going to be so fine I would have ordered a coarser grade. Otherwise as described in the listing.

​I finally decided to try this vermiculite for my indoor herb garden and it has been a total life saver for my "forgotten" plants 🌿 I used to feel like a failure every time my basil wilted after just one missed watering, but this stuff keeps the soil moist for so much longer. It was super easy to mix into my existing potting soil, and I love that it’s lightweight so I’m not breaking my back moving my heavy ceramic pots around the living room 🏠 ​The texture is really interesting—it’s like sparkly little flakes that keep the soil from getting all packed down and hard, which my new seedlings seem to really appreciate 🐣 I even used a handful to help root some mint cuttings in a jar, and they grew roots way faster than they ever did in just plain water! It comes in a resealable bag, which is a huge win for me because I always end up spilling half the bag of regular soil in the closet 🧹 If you’re looking for a simple way to keep your plant babies happy without hovering over them with a watering can every day, this is definitely the way to go 🌟 It’s made my Sunday gardening routine way more relaxing and a lot less messy.

Very small grade, very light, perfect. Thank you.

more than I expected;;great for mixing with potting soil for bulbs needing extra grit

ive never had a failed grow with this verm. it can be dusty upon opening but is easy to use. it does take up some space so i put it into a bucket because i had place for said bucket
