Broccoli Sprouts – 1 Quart Mason Jar Method
You will need:
• 2 Tablespoons of Broccoli Seeds
• 1 Quart Size Mason Jar (You can use a larger jar or sprouter if you would like, just be sure to adjust the seed quantity accordingly. For instance, if you are using a ½ gallon jar, you will require 4 Tablespoons of seeds rather than 2 Tablespoons).
• Sprouting Lid or Screen
• Fresh Water for Soaking and Rinsing
(1) Measure 2 Tablespoons of broccoli seed into a quart size mason jar.
(2) Cover the seeds with plenty of water and cover the jar with your sprouting lid or screen. Allow the seeds to soak for 8-12 hours.
(3) Drain the soaking water out of the sprouting jar, and then give the seeds a good rinse with fresh water. Drain very well.
(4) Rinse your sprouts thoroughly 2 times every day, morning and evening. It is important to drain as much water out of the jar as you can after rinsing to ensure the best sprouts possible.
(5) On the 3rd day, you can move your sprouter to a more sunny location, such as a windowsill. This will encourage chlorophyll development, and will make your sprouts happy. Make sure that this location is not too hot or extremely bright (this can dry out or even harm the sprouts).
(6) Your broccoli sprouts should be ready to harvest on the 5th or 6th day. Check for nice green leaves.
(7) Give the sprouts one final rinse and de-hull if you’d like. Be sure to drain the sprouts thoroughly prior to refrigerating.
There are many different types of seed sprouters available on the market that go beyond the simplicity of using a mason jar. You should feel free to use whichever one you like – the most important thing is that you use it! All you have to do is adjust the quantity of seeds you’re using per batch, based off the volume of the sprouting vessel you’re using. A good rule of thumb to remember with broccoli seeds is to use 2 tablespoons seeds for every quart sized growing space.

You will need:
• Growing Medium, such as Planting Soil or Coconut Coir
• 4 Teaspoons Broccoli Sprouting Seed
• 10” x 10” Growing Tray (you can use any size tray, just be sure to adjust the number of seeds accordingly)
• Spray Bottle with Water (for keeping the growing medium moist throughout the growing process)
A NOTE ON SOAKING SEEDS: When growing microgreens, these seeds can be planted either dry or soaked. There are advantages to both approaches. If you decide to soak the seeds prior to planting, you will find that germination comes a little faster and a little easier. However, it can be a bit challenging to spread the wet seeds evenly across the growing medium after draining their soak water. If you decide to plant the seeds dry, they are much easier to spread evenly across the growing medium. However, you will have to pay close attention to the growing medium during the early stages to ensure it is consistently moist enough for the seeds to germinate well.
If soaking seeds, soak in clean water for 8-12 hours prior to planting.
(1) Cover the bottom of the container with an inch or two of moistened soil. Flatten and level it with your hand, being mindful not to compact the soil.
If you’re using coconut coir or another growing medium, follow the manufacturer’s instructions or contact us directly if you need help.
(2) Evenly scatter the seeds onto the growing medium. Press the seeds gently into the soil, and then cover with a very thin layer of soil.
(3) Cover the growing tray with a lid or another tray. The key is to keep the growing medium moist so that the seeds can germinate well, and also to keep light out.
(4) Lightly mist the soil once or twice daily throughout the growing process. It is important that the soil stays moist, but not too damp (too much moisture can lead to mold). A good indicator is to look at the soil: you want it to always appear dark, not dried out.
(5) When your microgreens have developed leaves (usually after 3 - 4 days), its time to remove the cover and move the growing tray to an area with plenty of natural light. Continue misting the crop with water 2 times per day, paying attention to the moisture level of the soil.
(6) Broccoli microgreens should be ready for harvest in about 7-14 days. You may prefer to harvest a little sooner or later depending on your preference. Feel free to taste the greens throughout the growing process to see what you like!
It is important to keep the sprouting tray in an area where the temperature is consistently at least 60 degrees (day and night).
Remember - Growing microgreens requires a learning process, just like anything. Be patient with yourself, and know that you are developing a lifelong skill. It may take a couple attempts to master the process, but soon you will be a pro. Always feel free to contact us if you have any questions along the way – we’re very happy to help!
