Best Mason Jar Growing Kits for Home Sprouting and Microgreens
The best mason jar growing kit depends on what you want to grow. For a ready-to-use sprouting setup, Kitmiido and Boombamo include jars, lids, sleeves, and drainage accessories. For microgreens, choose a tray-style kit, and for DIY jar planters, consider the ORIMERC net cups. Check jar size and included components before buying, because some growing accessories do not include jars.
| Product | Best For | Jars Included |
|---|---|---|
| Kitmiido Seed Sprouting Kit | Two-jar sprouting with a stand | Yes |
| ORIMERC Net Cups | DIY hydroponic jar planters | No |
| Microgreen Grower for Mason Jars | Growing microgreens on paper | Not listed |

Kitmiido Two-Jar Seed Sprouting Kit
Best for: Beginners who want to sprout seeds in two jars and keep the setup organized. The kit includes two glass jars, two screen sprout lids, two blackout sleeves, a stainless steel stand, and a drip tray.
The stand holds both jars at an angle to support drainage and airflow, while the tray collects drained water. The blackout sleeves let growers reduce light exposure for seeds that benefit from darker conditions. The listed uses include bean, broccoli, and alfalfa sprouts.
Limitation: This is a sprouting kit rather than a microgreen tray system. Choose it for jar-based sprouts, not for growing a flat crop of microgreens.
ORIMERC Net Cups For DIY Jar Planters
Best for: Growers building their own hydroponic or self-watering planter setup. This pack contains 12 net cups, 12 feet of capillary wick cord, and 12 reusable plant labels.
The cups have slotted mesh sides for airflow and drainage, and a wide rim intended to rest on an opening. They can hold growing media such as expanded clay pellets while allowing water to pass through. The wick can help draw water toward a plant, making this set useful for DIY projects involving jars, buckets, or other containers.
Limitation: The package is an accessory set, not a complete mason jar growing kit. Jars and other planter components are not listed as included, so check container dimensions and opening size before choosing it.
Four-Piece Mason Jar Microgreen Grower
Best for: People who want to try microgreens using different tray depths. The package includes two deep and two shallow hydroponic germination trays plus 20 round sheets of absorbent seedling paper.
Fine holes in the basket bottoms allow drainage while letting roots access water. The included paper is designed to fit the baskets and help keep small seeds from escaping through the openings. The product description identifies radish and pea seeds as examples.
Limitation: The listing does not specify that mason jars are included or give a jar-size range. Confirm how the trays fit your intended jar before purchasing.
Two-Pack Microgreens Growing Trays
Best for: Growers who already own wide-mouth jars and want a simple tray accessory. The product is described as a two-pack for jar-based hydroponic sprouting.
The stated fit range is a glass jar inner diameter of 2.87 to 3.11 inches, with 16- to 32-ounce mason jars described as the preferred volume for stable sprouting. This makes the size details especially useful for shoppers comparing jar accessories.
Limitation: Jars are not included. Measure the inside diameter of your jar opening rather than relying only on the “wide-mouth” label.
Boombamo Premium Sprouting Jar Kit
Best for: Households looking for a complete two-jar sprouting setup. It includes two 32-ounce wide-mouth mason jars, two screen lids, two blackout sleeves, a stand, and a drip tray.
The sleeves are intended to help manage light for different seed types. The listing names broccoli, alfalfa, and mung beans among the seeds the kit can be used for. Since the jars and drainage accessories are included, this option is more complete than tray or net-cup accessories that require a separate container.
Limitation: The set is designed for sprouting in jars, not for growing microgreens in broad, shallow trays.
Buying Guide
Do you want sprouts or microgreens?
Sprouting kits use jars, mesh lids, and drainage stands to grow seeds into sprouts. Microgreen accessories use trays or baskets and may rely on absorbent paper. Choose a sprouting jar set for crops such as alfalfa or mung bean sprouts. Choose a tray-style kit if you want to grow microgreens such as radish or pea shoots.
Are jars included?
Check the package contents before ordering. Kitmiido and Boombamo list jars as included. The ORIMERC set contains cups, wick cord, and labels, while the two-pack microgreens trays explicitly exclude jars. The four-piece microgreen grower listing does not specify jar inclusion.
Will the accessory fit your jar?
For trays and net cups, measure the jar opening and compare it with the listed dimensions. The two-pack tray specifies an inner-diameter range of 2.87 to 3.11 inches. Also consider the stated jar volume where provided; that product identifies 16- to 32-ounce jars as its preferred range.
Which features matter for drainage?
Screen lids, angled stands, drip trays, and perforated baskets serve different purposes. A stand and tray help manage water from jars. Perforations help drain tray-grown seeds, while net cups provide airflow and drainage for DIY planter arrangements. Select the design that matches your growing method and counter setup.
Frequently Asked Questions
Can you grow sprouts in a mason jar?
Yes. A sprouting lid lets water drain while the seeds remain inside the jar. A stand and drip tray can help manage drainage between rinses.
Do all mason jar growing kits include jars?
No. Some products are accessories only. Review the package contents and confirm whether jars are included before buying.
What is the difference between sprouting and microgreen kits?
Sprouting kits typically use jars and mesh lids. Microgreen kits commonly use trays or baskets to support seeds as they grow on a surface.
How do I check whether a tray fits my jar?
Measure the inner diameter of the jar opening and compare it with the product’s fit specifications. Do not assume every wide-mouth jar accessory has the same dimensions.
Are blackout sleeves necessary?
They are included with some kits to reduce light exposure for certain sprouting seeds. If light management matters for your planned seeds, compare kits that include sleeves with those that do not.
