Growing Pea Shoot Microgreens in Paperpot Trays
Growing Pea Shoots Microgreens in Paperpot Trays
Won’t bend or break!
Larger trays = higher yields!
Matching solid bottom trays for easy watering!
Growing microgreens in Paperpot Trays gives you over 30% more growing space than standard 1020 trays, and they’ll last you a lifetime without breaking. This prevents you from needing to dispose of cheap plastic trays after just a year or two. Paperpot Trays also have low-profile side walls for better air flow, and convenient thumb holes for bottom watering when used with matching solid bottom trays. When stacking Paperpot Trays for germinating microgreens, there is a small air gap between the soil surface and the tray above, greatly reducing mold issues!
Pea shoot microgreens have long stems with leafy tops, and a sweet fresh flavor reminiscent of sugar snap peas. With a distinct crunchy succulent texture, pea shoots make an excellent addition to any salad, and can even replace lettuce as the base of the salad.
They are one of the most versatile of all the microgreens, hearty enough to be lightly wilted into hot dishes, much like you would with spinach. They make a great addition to stir fries, pastas, and rice. When preparing any of these dishes, simply mix in a handful of pea shoots to allow the residual heat from the pan to lightly wilt the pea shoots.
Pea shoot microgreens contain vitamins A and C, calcium, iron, and phosphorus.

Suggested Tools & Supplies
The best growing medium consistency for microgreens is composed of fine particulates with eve drainage. Too much drainage will lead to dehydrated crops, and too little drainage will lead to fungal issues.
Clumpy mix can be loosened up by hand when adding to your filling bin. Mix with larger particulates can be sifted through a DIY sifter made from 1/4” wire mesh on a box frame. This can be placed over a wheel barrow or tote to sift our larger material that may inhibit germination.
When filling trays with growing medium, make sure to spread it evenly in the corners and edges of the tray or microgreens in those areas will become dehydrated and tend to fall over.
After spreading the growing medium evenly in the tray, use a custom wooden press, or an empty tray to tamp/press the soil, creating a smooth even surface.
Spray down the growing medium with water prior to seeding.
Soil & Tray Preparation
Seeding & Germinating
Soak the dry seeds in a 5-gallon bucket of water lined with a paint strainer bag for 8 or more hours. After soak time, lift the strainer bag, dump the water, and tie off the bag to the bucket handle to drain. Allowing the seeds to dry a little makes them easier to spread when seeding.
Spread the soaked peas evenly over the tray. Press the tray once more after seeding to ensure good seed to soil contact, then water generously.
Seeded trays can be stacked up to six at a time, with an empty seventh tray at the top. Place a 14 lb paver on the top to weight down the trays, encouraging strong stems and vigorous growth.
Germinating trays do well at 70° and can be stacked in racks with no lights.
After 3-4 days the sprouts will begin pushing the trays up, and it’s important to monitor closely so the stack does not tip over.
After unstacking the trays, give them a thorough watering.
Transfer the trays to the grow racks under the lights, nesting them into the solid bottom trays.
16 hours of light per day is recommended for microgreens.
At this point, watering can be done by lifting the top tray by the thumbhole and pouring water straight into the bottom tray. Paperpot bottom trays have a line that provides a convenient reference point for how much water to add.
Bottom watering should take place once every morning. If your growing medium does not retain its moisture as long, water once more in the evening.
Stop watering 24-48 hours prior to harvest to ensure crops are dry and free from excess moisture. This helps greatly to extend the shelf life of the microgreens.
Growing & Watering
Harvesting & Packaging
Wash hands thoroughly and/or wear latex gloves before handling greens for harvest.
Sharpen the harvesting knife each time prior to harvest. To harvest, grab a handful of microgreens and cut just high enough above the growing medium to ensure there isn’t any stuck on the ends of the greens.
Carefully place the greens directly into the clamshells.
Scintilla Farms tip: place the clamshells into the refrigerator with the lids open for the first 10-15 minutes to avoid build up of moisture (after which they can be closed). This can increase shelf life.
Dump the harvested tray’s soil and root matter into bins or wheel barrows to be taken to compost.
Rinse, then spray down the tops and bottoms of the trays with 20ml of Zerotol 2.0 to a 2 Liter pump spray bottle of water, or a 1:1 hydrogen peroxide, white vinegar solution. Allow trays to dry in a rack prior to being reused.
Post Harvest & Tray Sanitizing
