Improve Moisture Retention and Aeration with Coarse Vermiculite

The Harvest Company premium coarse and chunky vermiculite is a natural soil amendment designed to improve moisture retention, aeration, and nutrient delivery in potting mixes and growing media. It helps deliver essential nutrients directly to plant roots, resulting in stronger root development, faster growth, and higher yields.

Its coarse structure provides additional airflow in the root zone, making it ideal for both beginner and professional growers.

Enhance Nutrient Retention and Soil Performance

The Harvest Company vermiculite naturally attracts and holds essential nutrients such as potassium, magnesium, calcium, and ammonium. These nutrients are slowly released to plant roots, providing consistent nourishment over time.

With its high cation exchange capacity (CEC), it supports beneficial microbial activity, improves wettability, maintains pH stability, and enhances overall soil performance.

Indestructible!
These dog chew toys have been a great purchase! My dog loves them and was interested in them right away. The shapes are fun and easy for my dog to hold while chewing, which keeps them entertained for a long time. The material feels durable and has held up really well even with regular chewing. I also like that it helps keep my dog busy and gives them something safe to chew on instead of furniture or shoes. Getting two toys in the pack is a nice bonus, and they seem well made for the price. Overall, I’m very happy with this purchase and would definitely recommend these chew toys to other dog own

Indestructible for the heavy chewers in your life!
My dogs can chew anything, and these are still in great shape! Very chew resistant to even my large dogs, and they love them! Easy to wash off if they end up in the food bowl or outside!

Not sure yet?
Only have had these for 24 hours but also purchased a couple other chew toys from Amazon as well and all were delivered at the same time. Point being that my #60 silver lab was trading off between all of them and after 2 hours only you can see little shards of plastic sticking up from these chews. Not sure how long these will last before having to throw them away but they are pretty nice and feel heavy and durable. So many of these companies claim they are “indestructible” but all 4 I purchased have little plastic pieces sticking up already. Even my #14 Shih Tzu enjoyed trying to chew these and it kept her busy even though they are for larger dogs.

My golden retriever’s really enjoy these chew toys. They are pretty durable and last awhile. They are hard plastic but they do get rough edges after they’ve been chewed in for awhile
