How to Use the Grow Kit
If you have an idea for a grow kit or want to show us your successes, post a picture of it to our twitter account @growgreenspace and use the hashtag #MyGrowKit so we can link it here.
The Instruction Card is Plantable, Too!
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! Detailed planting instructions are on the Earthy Goods website here.
Kit Modifications and Ideas
- 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 sunflowers!
- 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!
- 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!)
- Try making your own seed paper
- Harvesting tip: You can harvest the sunflower 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.
- We are working on some grow kit lesson plans for elementary, middle, and high school that will be compatible with the Next Generation Science Standards. Sign up for our email list to be alerted for when educator resources are rolled out.
Troubleshooting Common Problems
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.
- You can leave it alone. It takes about 3 days for seeds to germinate.
- 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.
- 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?
That white fuzzy stuff 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.
