At Rainbow On Bay we stand for naturally pure hemp products of the greatest quality. All or our hemp products are sustainably produced and offer the very best of the entire hemp plant.

All products are produced from hand-picked, hemp flowers using various extraction processes. This guarantees a THC (tetrahydrocannabinol) content of less than 0.2%.

All of our products are 100% natural. The hemp plants are carefully selected, grown with love and harvested with the utmost care under supervision. We prohibit the utilization of pesticides, herbicides and any chemical fertilizers. The hemp plants are naturally grown and selected to ensure that their CBD / CBDa content differs from normal hemp right from the beginning, which ultimately is why Rainbow On Bay’s products so unique.
