Reusing Microgreen Soil – I Messed This One Up, See The Proof

Our soil is a blend consisting of a coco coir base. We do sell it in small bags in the Home Microgreens Store. Click the button below to see our soil product page.

Here’s a photo of our results from reusing microgreen soil.

Even though we show that you can easily grow a new tray of microgreens on reused microgreen soil, we still do not recommend it.

The chance for disease is too great, and it takes some time to prepare the trays for planting. We’d rather throw the old soil in the compost heap and plant a new tray of microgreens on fresh soil.

Fresh soil leads to fresh microgreens. 

This is the reason we use soil over planting on microgreen mats.
