Pluses: they gave me extra seeds
Minuses: despite having brand new sprouting trays with nutrient dense soil, a cover to keep humidity in, and a heated seed mat, zero have sprouted in over a week. So that does make me concerned. Maybe I did somethign wrong? But also maybe I wouldn't have done somethign wrong had these seeds come with planting instructions.
I communicated that I wanted to return the seeds because I found another provider that had the seeds at a better value. Seed World contacted me and said they wanted me to keep the seeds and they would refund me half of the purchase price. I agreed and they did that almost immediately. They stand by there seeds and stand by their word.
