If your microgreens are growing unevenly, then you may need to be more methodical in your process. Make sure that you are sowing your seeds evenly throughout the soil. Check to see if the soil is good quality and research to see if it’s a match for your specific seed. Is your tray in a place where half of the tray is getting sunlight and the other half isn’t? This can lead to uneven growth and you may want to rotate your tray to ensure each side is getting equal amounts of shade and sunlight.
What to do if your greens start to rot
If your greens start to rot, you may be overwatering them. When a seed is getting too much water and not enough sunlight, it can lead to rot. If you’re having extremely sunny weather, water your seed once in the morning and once in the evening. If a cold front has moved in, then water your crop once.
Another factor that could be causing your microgreen rot problem is the water quality. Municipal water can contain chlorine which your plants won’t like. Using filtered water is a better solution for watering microgreens. Common microgreens prefer water with a pH level of 6.5. When you keep an eye on your water’s pH levels, your microgreens will be healthier and produce stronger, increased yields.
