The picture above shows several nice trays of microgreens growing. But there seemed to be some new challenge and lesson every week of my first season as a microgreen farmer.
-poor drainage in trays until I cut more holes in the bottom
-Buying the wrong seed
-dealing with rain
-dealing with heat, and frying a few batched of trays with the plastic lid covers
-varieties that flopped like lentil, chic pea, and corn shoots
-trying a supposedly fail proof indoor system that failed
-Then there were the chipmunk attacks
-And even when I had a bumper crop, a rainy day at the market resulted in slow sales
I set up a fence to protect my microgreen trays from deer and wood chucks, but I never thought about chipmunks. They can get in anywhere, and they love sunflower seeds. The real problem is that they like to dig around in the trays, and once they uncover the seeds, the seeds dry up and die. They ruined a weeks worth of trays.
I set up this system of a brick frame with some hardware clothe on top, and bricks on top. If you are more of handy person than me, you could build a wood frame. Once the seeds sprout to about an inch they are safe because the chipmunks only seem to like the seeds, and not the sprouts.
This system is also great for sprouting seed starts outside. Stadium Hardware sells hardware clothe by the foot/yard.
