For the most part, no, it doesn't matter if hemp is certified organic. However, although hemp farmers growing hemp without organic certification don't typically use pesticides or artificial fertilizers on hemp, organic certification is still nice to see. That's because hemp fiber may be treated with harsh processing chemicals during or after harvesting, in part to make the process faster and cheaper. With GOTS certification, there's a very strong chance that both the hemp and any processing chemicals are organic, safe, and sustainable. That's why we love Avocado's organic hemp sheets so much!
