This innovative product is the most environmentally friendly plant container on the market. CowPots transplanting pots and seed starting pots are made from odor-free, 100% composted cow manure. Fully decomposable CowPots feature natural soil-conditioning fertilizers and can be planted directly into the soil to grow sturdier, healthier plants without adding plastic containers to your local landfill. The pots are easy to handle, 100% odor-free and non-toxic.

There are more than a dozen sizes of Cow Pot seed starter containers for hobby growers, commercial growers and nurseries. Square pots can be used with our Square Pot Carrying Trays while round pots are ideal for 1020 trays, giant garden trays and more. When completely buried, CowPots will start decomposing within a few weeks. They can last months above ground, letting you grow larger seedlings and sell them in the pot at retail centers. We have huge discounts on large CowPots cases to save growers money.

Uses for Cow Pots:

#3 Square - 3" long and wide x 2-7/8" tall
Preferred for herbs, vegetables or other annuals intended for quick turnaround from seeding to transplanting. A convenient size to step up to larger planting containers or direct transplants to ground post frost.

#3 Round - 3.25" diameter x 3-3/8" tall
The round pot allows for better ventilation and air circulation between pots, which is advantageous to longer term durability. This size is preferred for seed starting of herbs, vegetables or other annuals that will be used for stepping up to larger planting containers or direct transplants to garden.

#4 Square - 4" long and wide x 3.75" tall
Preferred for seed starting of early planting annuals and vegetables. Ideal for seedlings needing more days in the greenhouse before transplanting. It's also great for stepping up transplants to larger planting containers or direct transplants to ground post frost.

#4 Square Tall - 4.5" long and wide x 4-3/8" tall
Optimal for vegetables that need more time in the greenhouse before transplanting to the field, like peppers, tomatoes and eggplant. This is also a closer match to the standard four-inch pot size used for perennials and herbs.

#4 Round Tall - 4-3/8" diameter x 4.5" tall
This style, like the #4 Tall, offers more soil volume than the standard #4, and the round sides improve air flow between pots. This can be advantageous to reduce mold.

#5 Round - 5.5" diameter x 4.75" tall
Great for transplanting of ornamental peppers, small mums and perennial herbs. The shape makes these plant pots easy to incorporate into indoor/decorative planting containers as well. It's also a good size for setting up bulbs mid-winter.

#5 Square - 5.25" long and wide x 5" tall
Great for use by landscapers using larger plant material. Especially applicable for planting woody herbs like rosemary, thyme or sage. The soil volume of the #5 Square is a good fit as a step up planting container for tomato seedlings. This is the most compact CowPot of the larger plant pots (depth to width ratio) and is intended for direct planting into the ground.

#6 Square - 6 in. x 5 in. tall
Used by avid dahlia growers. Also suitable for planting woody and/or bushy perennial herbs. The larger planting container size maintains the ability to rapidly decompose once planted. Optimal shelf life for these biodegradable plant pots is up to 16 weeks once planted.

#6 Round - 6" diameter x 4.25" tall
Great for planting woody and/or bushy herbs like rosemary, sage and thyme. Most suitable for late season crops, including chrysanthemums. A round biodegradable pot permits good air ventilation, allowing planting container walls to dry and harden in between watering.

#7 Square - 7" long and wide x 6-1/8" tall
Great for planting woody and/or bushy herbs along with vegetables that need more time before transplanting. Large flowers like Cannas are also a good fit in this biodegradable planting container. The larger pot size maintains the ability to rapidly decompose once planted.

#11 Square Tall - 8.5" long and wide x 11" tall
Designed specifically for growing perennials (seasonally). The #11 Square Tall is a deeper planting container, improving soil volume for healthy root growth for longer term plants using biodegradable plant pots.

#12 Square - 11.5" long and wide x 7" tall
Used in our own greenhouse for planting bulbs, large chrysanthemums and biodegradable combination planters. Growers have used this planting container size for grape vines and tomatoes as well.

#17 Round - 16.5" diameter x 11.5" tall
Originally designed for live Christmas tree sales, this is also a great pot for combination planters. Exciting way to display and market mixed flowering annuals or mini vegetable gardens. This biodegradable planting container can be easily transferred to a large step up pot with no mess.

Wish I would have found them sooner. Will be back for more!

The roots grow right through!

We have been happy to be able to tell others that these potted plants can be put straight into the ground, and the roots grow straight out of the pots, with no transplant shock.

Love Cowpots

I’ve used the smaller cowpots for several years and this is the first year using the 4” squares. They work well for up potting larger seedlings. I like using a renewable resource for my pots and having an extra bit of nutrients for my soil.

Michael Champion (Seattle, US)
My go-to pots for years now

And they're economical when buying in the quantities GH Megastore sells

Thank you.

Works fantastic. Start my seeds in smaller plugs then place them in these cow pots. Then plant directly in garden. Thanks

No transplant shock

Have used the square pots #3 and #4 square tall for 2 years now. Followed watering directions, and have had no problem.

The lure of Manure

Since I'm starting my plants outside the soil stays moist and the pots mostly dry. When it's going to rain hard or extensively I bring the trays inside. I'm really pleased.
