This fine vermiculite is suitable for topping seeds after sowing.The 2 cubic feet bag is a good value. Plants requiring consistent moisture will benefit from adding this fine vermiculite to their potting mix. The fine consistency is perfect for mixing with potting mixes, if your goal is moisture retention. It's easy to use and lightweight. The bag it comes in is reusable and durable. I definitely recommend this product. However, be aware that it will retain a great deal of moisture when mixed into growing mediums. Some plants will not thrive in such a wet environment.

I have heavy soil with clay, and this really helps to break it up make it a little bit more manageable

It came exactly as described, what I had in mind was coarse vermiculite. So I used this instead as a soil amendment around peppers , squash and tomatoes instead and it seemed to work great, it really conditioned the soil nicely and broke up the clumps of dirt around the roots. So in the end this also seems to have been a tremendous value. Only time will tell. My second attempts at this was the coarse grade of vermiculite same application, basically I cultivated the product into the base of the garden plants. The idea here is to amend the soil slightly so as to reduce the need to water as much.

Being tired of flies and gnats around my seed trays and seedlings, this year I am using vermiculite instead of potting soil. It is working well so far. Germination good, seedlings happy, and no flying insects around them!!

This large bag mixed very well with my raised bed mix, compost, etc. to help promote drainage in my 6’ x 6’ raised bed. I already have potato seedlings breaking ground. Good stuff!

I bought this to store my dahlia tubers and I overestimated how much I needed. It’s a huge box that will last me several years!

*edit* - I'm happy to see that the company has updated their product listing to reflect the grade of the vermiculite. Original review: When geared toward gardeners, vermiculite is usually sold by estimated volume (quarts or cubic feet) rather than weight, which is not terribly accurate given how much it settles. For an apples to apples price comparison, I always compare product weight for the best deal. This usually serves me well. When I bought this, it was the best deal on Amazon for 15 lbs of gardening vermiculite (note, the price has since been raised considerably). Then the box arrived, and it was so small compared to what I was used to for this weight, I thought maybe it had been split into two packages. Unfortunately, no. Gardeners' vermiculite is normally a very coarse grade, thus I'm used to 15 lbs filling at least 2 cubic feet. This is very fine and not suited to raised bed gardening. I won't return it, as it will be useful for other purposes, such as rooting cuttings, or dusting atop surface-sown seeds. The fault is mine for not inquiring as to the grade of the vermiculite before purchasing. Again, there is nothing wrong with the product and it does have its applications, but be aware that this is NOT the coveted coarse grade vermiculite sought by gardeners. *edited to add* Uncool when sellers five-star their own products to inflate ratings.
