Stretch, who is also a registered processor, said he was approved for his grower registration in around 40 days. Jacob Williamson, owner of Hens and Hemp, said he is registered as a grower and is on his way to becoming a registered processor. Williamson said having both permits is worthwhile because of their low cost and the extra level of protection it provides -- since growing and then drying, trimming and packing hemp could be considered processing. Williamson, like many other small farmers, mainly grows hemp to be sold as CBD products.
