Hemp Seed Compliance Documents

Visit the link below to find our compliance documents needed for hemp cultivation. This includes our hemp grower licenses, handlers licenses, Oregon Tilth Organic Certification, and COA's.

Please be aware that our COA's are pre-harvest compliance results obtained 30 days before harvest as per USDA rules, and, as a result, are not an accurate representation of the final CBD/CBG/CBDV concentrations. If you do not see a COA, the variety cannot be grown as hemp.

For varieties that produce predominantly THCA (THC), they will never pass pre-harvest compliance tests taken 30 days before harvest or 60 days before harvest. Even leaves sampled during the vegetative state have been shown to contain more than 0.3% total THC.

Compliance Documents


For those seeking test results on trimmed flowers, we recommend visiting a flower retailers website such as Fern Valley FarmsHorn Creek Hemp, Rogue Origin, or Tweedle Farms. We cannot guarantee finished flower results, so we do not post them.

All of our CBD varieties will pass USDA hemp sampling requirements for total THC if tested around 30 days before harvest -  and with our high CBD varieties this needs to be done by the end of the 4th week of flower. In most cases this is the end of the 2nd week of August, but later planting dates can delay flower onset. We say sample when the flowers are around the size of a thum.

If you wish to push this date further when growing our high CBD varieties, weekly plant samples will need to be analyzed to ensure material does not exceed regulations for total THC content. Our CBG varieties will remain compliant even until the day of harvest and beyond. Our CBDV strains will in general remain below 0.3% total THC on the day of harvest as well.

Growing High CBD Seeds

Growing CBD varieties that produce high CBD will virtually always yield finished flower that has more than 0.3% total THC - if accurately tested. The gene in CBD plants that is responsible for CBD production, the CBDA synthase, also produces THCA throughout the plants flowering cycle. So as it makes CBD, it also makes THC - and at a consistent ratio of around 25-28 parts CBD to 1 part THC. This ratio cannot be altered by growing conditions, harvest date, or any other factors.

For example, if you have a finished and dried CBD flower with 25% CBD, you can reasonably expect it to have around 1% total THC. If you have a CBD flower that has 12.5% CBD, you can expect it to have around 0.5% total THC. Plants sampled throughout flower show the same ratio, just differing quantities of both CBD and THC. With this in mind, a CBD flower cannot have more than around 7% CBD before it also has more than 0.3% total THC. This is why sampling 30 days before harvest is important as both the CBD and THC numbers raise quickly in the plants final weeks of flower.

Many of our varieties such as Hawaiian Haze, Lifter, Sour Chem, Sour Lifter, Sour Suver Haze, Special Sauce, and Suver Haze frequently hit at or above 20% CBD and around 0.8% THC. Sampling at the correct time is very important - around the end of week 4 of flower.  As mentioned, this is true with all high CBD seeds, and not just ours. 

Selling High CBD Flower

With the current USDA loophole, as long as your flower has below 0.3% Delta 9 THC it is deemed hemp for legal sales - but some states have stricter legislations in place. Look into your local laws and ordinances before planting. 

Growing THCA Seeds

THCA seeds, which are the same as THC seeds, cannot be grown as hemp. Even sampled in their vegetative states, THCA dominant plants leaves often have higher than 0.3% total THC. A week into flower and that number is usually around 1%. There is no way to pass pre-harvest compliance tests with THCA/THC seeds so do not even try. But we do have some really nice seed varieties here.

Selling THCA Flower

THCA flower is just regular THC flower. All THC flower contains mostly THCA and the plant itself does not produce Delta 9 THC - which is what is the compound that gets users high. Delta 9 THC is a degradation bi-product of THCA and converts through heat. Fresh cannabis picked right off the plant will rarely ever have Delta 9 THC - but shortly after harvest small portions convert. If you choose to sell THCA flower, just realize it is just regular THC flower, and it will likely have above 0.3% Delta 9 when it reaches the shelves of shops.
