Biodegradable 6-Cell Seed Starter Inserts – CowPots® #3

Eco-friendly seed starting made simple with biodegradable, compostable pots.

The CowPots® #3 6-Cell Inserts are a sustainable alternative to plastic seed trays, designed for starting vegetables, herbs, and flowers in compact spaces. Each tray holds 6 biodegradable seedling pots that can be planted directly into the soil—where they break down naturally, enrich the soil, and reduce transplant shock.

Perfect for garden packs, salsa kits, and quick-transplant crops, these pots are durable enough to last up to 2 months in greenhouse conditions yet fully compostable after planting. With their scored design for easy separation, they make transplanting fast, clean, and efficient.

Why Choose CowPots®?
