The grow kit is also fully biodegradable and ecofriendly! The container, baggies, and drip tray are made from biodegradable plant-based materials and the instruction card is recycled paper filled with wildflower seeds that you can soak and plant when you’re done with it.

  • GROW MICROGREENS AT HOME with our easy-to-follow instructions
  • SUNFLOWER MICROGREENS are a tasty gourmet delicacy for salads, sandwiches, and garnishes
  • MICROGREENS contain larger quantities of phytochemicals as well as Vitamin A, E, C, and K
  • ZERO WASTE from this fully biodegradable and ecofriendly kit
  • A GOOD EDUCATIONAL TOOL for teaching students about plant growth and sustainability

Is the grow kit container reusable or single use?

The grow kit container is reusable to plant more pea shoot seeds, other microgreens, or simply as a container. However, we do not recommend that you use the container for hot items and suggest that you avoid washing with too hot of water, otherwise the container will melt. But if you want to reuse the container for growing more microgreens, then go for it!

Our product containers are made of polylactic acid (PLA) which is a resin left over from processing corn. Corn is a renewable resource that is carbon neutral. Corn can be regrown year after year to make more PLA, and because it is a plant, it takes up carbon dioxide from the atmosphere when it grows. This is more than anyone can say for petroleum, which is what typical plastic containers are made from. The containers are also fully biodegradable, meaning they will break down in your trash or compost and will not accumulate in landfills. Here’s a great Smithsonian Magazine article if you want to learn more about PLA!

The Plantable Instruction Card

The instruction card included in your kit is also biodegradable and as a bonus, it is embedded with wildflower seeds. This special seed paper is made by a company called Earthy Goods. So, when you are done with your grow kit and you’ve composted all of the materials, you can take the instruction card and plant it in the ground to get flowers!

Grow Kit Lesson Plan

Receive a complementary lesson plan with the purchase of 10 or more kits! For fewer than 10 kits our lesson plan is available for purchase. This workbook contains two lessons that are aligned with the Next Generation Science Standards for Grades 3-5. They are titled “The 5 Needs of Plants” and “Biodegradable Materials.”

Kit Modifications and Ideas

  1. Leave a few unharvested as flower starters. You can let some of your microgreens grow all the way out into seedlings and then plant them outside to let them grow into mature planets!
  2. Close the loop — bury the kit in the ground when you are done with it and plant the wildflower instruction card with it, bringing back everything right where it started in nature!
  3. Save the sugar container to use as a to-go box for salad and wash it only with cold water to keep it from melting. (Not dishwasher safe!)
  4. Try making your own seed paper
  5. Harvesting tip: You can harvest the microgreens as they are ready. Some might grow faster than others, so if you want to avoid letting some grow too much to let the stragglers catch up, go right ahead and harvest when they are ready! You might even get a second round of growth once you prune away the big ones.
  6. Get our lesson plan book for grades 3-5 and take your grow kit experiment to the next level!


I need help figuring out how to do Lesson 2.

Well, you’re in luck! Now there are supplemental instructions online via Instructables for free, with pictures!

Why won’t my seeds sprout?

Did you plant your seeds and nothing is happening? It may be just fine, and you have a few options.

  1. You can leave it alone. It takes about 3 days for seeds to germinate.
  2. You can give it a few more days. It might take a little extra time to sprout if the seeds weren’t wet enough or if it is too cold. Next time, try soaking the seeds for 12 hours before spreading them and it should speed things up.
  3. Your seeds might be too dry. Make sure you are misting and watering according to the instructions.

My microgreens are too short and stumpy.

Try germinating the seeds in the dark for the first 24 to 48 hours before moving them into the sunlight. When there is light, the plants will show leaves sooner and do not need to become taller to access readily available light. So, make them work for it! Let the plants germinate the dark first and they will continue to get longer as they “reach” to find a light source. Once you put them in the sun, they will get greener and their cotyledon will open up and sprout! Voila!

What’s that white fuzzy stuff on the surface of the soil?

There are two things this could be.

One is that they might actually just be root hairs and are a normal part of the germination process. In that case, there is no need to do anything! If it looks like it is mainly on the roots and not all over the soil, then this is probably what you are dealing with.

Another thing it could be is mold. Don’t fret, though, it’s not harmful. It can happen when there is too much moisture on the soil, usually because the lid has been placed too tightly. When you are waiting for the seeds to germinate, you only need to leave the lid on loosely to hold in some of the moisture, while still allowing sufficient air flow. You may also leave the lid off completely and mist the seeds with water more frequently.
