Rules for growing microgreens indoors

February 23, 2018

Next winter you'll most likely want to grow microgreens outdoors(kidding). Or you might already know how to grow but need a little help (or you just don't want to admit why your microgreens died); either way we will be giving you some rules to follow, while you travel on the road to success.

Equipment & System Needs

The Heating System hoophouse is passive solar heated, which works fine for starting plants in earliest spring, but for growing a consistent crop of microgreens during cold and low solar months of winter, it needs to be supplemented. After research that was done, it was determined that heat mats were the most efficient direct heat option. There are several options to heat the water: electric, solar and bio gas.

Water is an essential component for microgreens needs, which constantly needs to be kept at an ideal moisture level. This then makes the water accessible for the growing area. Watering equipment for our system remained pretty simple: long hoses which run along the length of a table with long neck spray nozzles that release a gentle shower. These happened to be the most flexible performers and provided good coverage.

Ventilation by large fans is essential to prevent fungus in winter and keep microgreens cool in summer. They act to keep the growing constant. Ventilation is essential to the success of the growing operation.

Working towards developing a system for your clients based on climate, farm setup and prospective buyers

To keep track of all the crop varieties in trials, you should develop a simple log to track all the pertinent information for each trial. Document the date of the seeding, the media used, tray size if used, quantity of trays, whether you applied heat or not, quantity of seed used per unit, harvest yield and harvest date. With solid note-taking, you will be better able to track the successes, failures and troubleshooting, to minimize the latter. So, we recommend this as a practice. Documentation was important not only in trialing seeds, media, and growing conditions, but during later steady commercial production as well. Keeping good notes, not just numbers on all the variables, was key to seeing what types of systems worked best in our setup.

Growing Medium

You'll have to decide what you want to use for soil. Whether it'd be coir or potting soil. You'll have to decide which is best for you and figure out the ratio that best suits your growing needs. Be sure to always experiment in this stage.
