The dissolvable pouches are made out of a Certified-Edible PolyVinyl Alcohol film. This material is most commonly used in gel casings for pills, as well as in the laundry pod industry. Everyone always jokes "so it's an actual edible laundry pod!?", and yes, you can safely eat our dissolvable pods, but there's manure in there, so we wouldn't recommend it ;)
The Seedsheet™ is made from a #5 recyclable non-woven polypropylene weed-blocking fabric. It is a flexible, breathable, and perforated fabric, not a black plastic sheet. Water is able to drip through the material, and perforations help airflow to prevent soil mold and root rot. At the end of your garden's life you can recycle the weed-blocking fabric, or save to reuse next season.
The fabric garden container is constructed of BPA-free ♳ PETE, extracted from recycled plastic bottles! The breathable fabric helps the soil drain, and airflow prevents root-circling and results in healthier root systems and ultimately happier plants!
