Home Microgreens Potting Mix – Premium Seed Starting Soil


This professional blended premium seed starting soil and growing mix will germinate and grow your microgreens like no other soil on the market.

Soil is sold by the volume of the Home Microgreens trays.

Packages of soil come in two sizes. One will fill one Home Microgreens tray. We also sell a bag that will fill 4 Home Microgreen trays. The larger bag is approximately 3-quarts.

This is the same soil we use at Home Microgreens, and we won’t use any other. We love it!

See the note in the description about storing soil.

Choose the soil bag size below from the dropdown menu.

Available Options

Soil for 4 HM trays$5.99
Soil for one HM Tray$1.69

This professional blended premium seed starting soil is ideal for germinating and growing your microgreens.

We have improved this soil! Due to supply issues for some of the ingredients, we were forced to come up with a new mix and we are so glad our hand was forced!

The new blend grows quickly growing microgreens as well as our old blend. The improvement is with longer growing microgreens such as basil, chard, cilantro, etc. In head-to-head trials, basil, chard, and cilantro grew better and were much darker green than our old mix.

The soil contains coco coir, sphagnum peat moss, earthworm castings, perlite, poultry litter, feather meal, bone meal, biochar, potash, diatomaceous earth, gypsum, leonardite, and beneficial microbes.

The soil is light, has a more consistent texture than the older mix. It holds more than its weight in water.

The peat moss replaces the aged forest product but. does not reduce the wetting time.

Soil is sold in 2 sizes. Chose the size in the dropdown menu to see the price. The sizes are:

  • Refill for Home Microgreens trays – these are the new black trays (7.5 X 5 X 1.5 inches).
  • Refill for four Home Microgreen trays.

For reference, a 5-inch by 5-inch tray can be filled with one Home Microgreen refill.

A 10- by 10-inch microgreen tray can be filled with three Home Microgreens refills.

A 10- by 20-inch microgreen tray can be filled with about 5 Home Microgreen refills.

Note: The soil will be shipped in a tightly sealed plastic bag. Do not store the soil in the closed plastic bag for very long. Moisture will build up. Store the soil in a tote or open the bag and store it that way. For more information see this post.
