Mejale Rice Hulls 1.8 Quarts, Horticultural Grade Rice Husks for House Plants, Greenhouses, Vegetable Gardens, Organic for Plant Fertilize, Bedding Nesting for Chicken & Other Animal

Small bag of rice hulls. I mixed these into one of my garden beds to help with drainage. No ill effects.

I found out about using rice hulls as a soil supplement relatively recently. This is my second product to try it out.I use it in my potting mixes for water retention and to fluff up the soil a bit. I'm using it essentially the same as I would vermiculite or fine perlite. It has the added benefit that it'll decompose over time, releasing some nutrients and feed the earthworms in the soil.I haven't noticed any bad effects so far and the plants in my potting mix seem to be liking it.
