Discover the art of perfect moisture for thriving microgreens! Whether you’re a seasoned gardener or a beginner, understanding the delicate balance of humidity and watering is key to lush, healthy mini greens. Let’s delve into the methods that ensure your microgreens don’t just grow, but flourish. Here’s how you can start to master microgreen moisture control.

Optimize Humidity for Germination

During the initial stages, your microgreens crave a cozy, humid environment to kickstart their growth. Mimic this by using a dome over your tray, which should be about 2 to 4 inches high. Keep an eye on the temperature, maintaining it under 75F, to prevent overheating and excessive condensation. If droplets form inside the dome, like in the picture below, swap it with a dry one to prevent humidity levels from climbing too high.

Strike the Right Balance Post-Germination

Once your microgreens have sprouted, it’s time to introduce them to their new world. Place them under a light and slightly lift the dome to gently welcome them to their new environment, which toughens them up gradually. After a day of acclimatization with the dome propped, the seedlings should be dry, signaling it’s time to remove the cover completely.

Mastering Bottom Watering Technique

The best way to quench your microgreens’ thirst is through bottom watering. Pour water into the tray’s bottom and let the microgreens soak it up. This spa-like treatment should last no longer than three minutes to prevent overindulgence. Remember to drain excess water; your microgreens love a drink but they don’t enjoy swimming.

Balancing Water and Air for Healthy Roots

It’s all about harmony in the tray. Water and air share pore space in the substrate so balance is key. If water lingers at the bottom, the roots might suffocate, leading to rot. Keep your microgreens happy and healthy by ensuring their roots breathe as freely as they drink.

Tailoring Your Watering Schedule

Watering every other day is generally a good rhythm, but stay attuned to your microgreens’ needs. If the substrate dries out faster than a sunny day at the beach, consider daily watering, a thicker substrate layer, or mix in a bit of vermiculite with your substrate. Remember, your microgreens rely on your watchful eye for their hydration needs.

Empower your microgreens with the right moisture techniques and watch them stand tall and vibrant. By controlling humidity, perfecting watering practices, and adjusting to their needs, you’ll be on your way to a microgreen oasis.
