Growing with Hydroponics
Tips for Growing MicroGreens 


Microgreens are easy growers and it's unlikely you'll have any problems.  Here a several growing tips - and equipment - you might want to consider for growing more advanced crops.


Seeds - To Soak or Not to Soak

Some microgreen varieties require a presoak, sometimes up to 8, 10 or 24 hours. It is generally recommended to soak larger seeds like sunflowers and peas to soften the outer seed coat. Wheat grass is another seed that needs to soak before planting.

Any seed that needs soaking, we recommend that you use hydrogen peroxide at full strength (drug store brands) for at least an hour before commencing the soak cycle. Seeds that are stored for any length of time can have mold spores on them just waiting to turn into mold at the first sign of moisture. When soaking these seeds, you’ll see the reaction of the hydrogen peroxide on the outside of the seed. Let them sit and soak, rinse in a colander, and then soak some more in plain water. 

What About Nutrients?

Mother Nature packs seeds with nutrition and energy, and with microgreens there's enough to last until harvest. This means that fertilizer is not needed.

Some people do provide mild fertilization, but most crops truly do not need it. 

Humidity Domes

Humidity domes come in handy if your house has low humidity. Seeds must stay moist to germinate and humidity domes keep them from drying out.

In most cases, you’ll only use a humidity dome during germination and perhaps through first few days of the growing cycle. You’re trying to maintain the delicate balance between too much and too little moisture. 

There are many humidity domes available. Some are vented in case humidity inside the dome becomes excessive.

Heat Mats

Seeds also need gentle warm temperatures to germinate. Heat mats keep your seeds warm, perfect for growing in a cooler spot like a basement. Simply place the mat beneath your tray and plug it in.
