Bootstrap Farmer
CowPots 4 Square Biodegradable Seed Starting Pots
CowPots 4 Square Biodegradable Seed Starting Pots
CowPots 4 Square Biodegradable Seed Starting Pots are an eco-friendly option for starting seeds that require extended greenhouse time before transplanting, such as eggplants, tomatoes, and peppers. Made from 100% renewable cow manure fibers, these pots decompose into the soil, enriching it as they break down, and their tall design supports extended root growth for transplant-heavy crops.
Each cell holds 450 mL (27 cu in / 1/2 quart) and measures 4” x 2 1/2” x 3 3/4”. Ten #4 Square CowPots fit in Bootstrap Farmer’s 1020 Deep Tray without an insert. The pots are fully biodegradable and compostable and can be transplanted directly into the ground without disturbing delicate roots. They are available in packs of 20, cases of 110, or cases of 330, made in the USA and available to customers in the United States. They are suitable for early planting annuals and vegetables with longer greenhouse cycles and have proven use in commercial step-up applications to soilless bag cultures.

from 74 reviewsGreat product and delivery
Really nice soil and awesome service
Never used because I ordered the wrong Water Filter. Mike was very helpful with the return and refund. Excellent Customer Service.
Great service. Soil is what I wanted and it off loaded exactly where I asked.
Plants are doing really well with this soil. Deep and rich looking soil, plants seem really happy. Much more cost effective (and no plastic bag waste) compared to buying bags of soil mix from a store.
Thank you for shipping so soon. Great service
The quality of the craftsmanship is superb! My formula one fan absolutely loves it!!!!
Worked like an absolute charm!
These markers were perfect for ones that we were replacing. The quality is great and they seem sturdy. The gold detail stands out and is visible from a distance. Shipping was very fast.
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
