Plantonix Vermiculite Bliss is a 100% natural, fine grade vermiculite that holds nutrients and moisture in the soil and releases them to plant roots over time. Blended into a mix, it also increases oxygen flow to roots and improves drainage.
Each bag is clean, odor-free, and sterile, which makes it suitable for seed starting as well as vegetables, flowers, and container plants indoors and out. Like other mineral soil conditioners, it is designed to be mixed with potting soil, coco coir, or garden soil, so plan to use it as one part of your blend.

A Sterile, Fine Grade Vermiculite for Seed Trays and Stretching Soil in Beds and Containers
If you start your own transplants, the sterile, fine texture of this vermiculite is what makes it fit. You can blend it into your seed starting setup or spread it over sown seed, where it holds steady moisture without introducing odor or contaminants. It also suits you if you mix your own container or bed soil and want better nutrient and water holding without added weight.
For plants that need both moisture and fast drainage, the manufacturer recommends combining it with horticultural perlite. The 24 quart bag gives you enough to amend a sizable batch of soil. If your mix calls for large, chunky particles, look at a coarser grade, since this one is fine.
What to Expect from the Plantonix Vermiculite Bliss in Real Use
Verified Amazon purchasers describe the material as clean and consistent, and several rate the quality above other brands they have used. It is reported to mix into garden soil easily without turning into a dusty mess, leaving beds and containers lighter and easier to work.
A second report agrees that dust levels were reasonable and adds that the particles were not too small. For seed starting, a grower who tops seedling trays with it says seeds push through easily and that the layer helps prevent algae growth on the surface. On volume, purchasers say the bag covers multiple gardening projects, and one who uses it to stretch and improve the soil in raised planting beds reports getting more than a wheelbarrow full of mix from it.
Opinions on particle size vary with the intended use. While some find the size right, another purchaser judged the grain too fine for their purpose and plans to choose a coarser product next time, while still rating the quality as good. Check your intended use against a fine grade before ordering.

Frequently Asked Questions
Should you mix perlite and vermiculite together?
Yes, you can, and the manufacturer recommends combining the two for indoor and outdoor plants. Vermiculite holds moisture and nutrients and releases them to roots over time, while also improving oxygen flow and drainage in the mix. Adding perlite alongside it gives you a blend that retains water without becoming waterlogged. This vermiculite blends easily with perlite, potting soil, and coco coir.
Can you cover seeds with vermiculite in seed trays?
Yes. Fine vermiculite works as a top layer over seed starting trays. It is light enough for seedlings to push through easily, it holds moisture at the surface where seeds need it, and it helps prevent algae from growing on top of the tray. This vermiculite is sterile and odor-free, which suits it for use around germinating seeds.
Can you add vermiculite to raised bed soil?
Yes. You can mix vermiculite into raised bed soil to stretch the volume and improve its texture, keeping the soil lighter and easier to work. A 24 quart bag can amend more than a wheelbarrow full of mix. Keep in mind that this is a fine grade, so if your raised bed recipe calls for coarse vermiculite, confirm that a finer particle fits your plan before using it.
