Frequently Asked Questions

What Would You Like to Know?

What is in your soil-less mixes?

Our mixes are made from down stream waste products, like rice hulls, compost, and coconut fiber.

What do you grow?

We grow over 20 varieties of produce, from greens in the spring to pumpkins in the fall. We grow several varieties of tomatoes, squash, and peppers, as well as several other vegetables.

Is your produce chemical free?

We are a certified organic farm operation. All our products are non GMO and pesticide free.

What are the downsides to using Peat, Perlite, or Vermiculite in soils?

Peat offers high absorbency when treated with a wetting agent, acidic pH, and compaction prevention properties for soil. Organically approved wetting agents typically have a shelf life of less than one year. However, peat doesn’t contain nutrients plants need to grow. Peat is not considered renewable and regrows at less than 1mm per year.


Perlite aids with soil aeration. It has an alkaline pH. However, it is a strip-mined product that requires energy, and can have a detrimental effect on the local ecological environment. In addition it is then heated to 1650 degrees F to be useful. It is also non-renewable.

Vermiculite aids with water retention but is poor for aeration. It can also raise the pH some. Vermiculite is best for plants that require soil that stays moist. Additionally, vermiculite must be exfoliated to be used in soil mixes and can contain trace amounts of asbestos, a known carcinogen, if it is too dusty.

What do the rice hulls do?

The rice hulls aid in aeration and drainage, and add silica as they decompose. They are a waste product from other industries, are renewable and sustainable, and are less expensive than perlite.

What is coconut coir (fiber) and what does it do?

Coconut coir is made from the fibers found between a ripe coconut’s shell and outer surface. Coir improves water retention, possesses aeration properties, and has a neutral pH. In addition, it is renewable and sustainable. We use an OMRI-approved coir washed for growing.
