What Makes Our Feminized Hemp Seed Different?


Guaranteed Plant Count Germination

Starter Packs– The germination rate for our feminized hemp seed exceeds 90%, depending on the batch. We add 10% to any feminized hemp seed Starter Pack to make sure our hemp farmers have all the plants they planned for.  If the order is for 100 female hemp seeds we will ship 110 seeds.

Bulk Hemp Seed Orders – We guarantee a 100% germination plant count on all bulk hemp seed orders of our feminized hemp seed strains.  We extensively test the germination rate after we harvest our feminized hemp seed batches.  If the batch’s germination rate is 95% we add an additional 5% to the order.  For example, if the bulk seed order is for 10,000 seeds, and the batch tests to a 95% germination rate we will ship 10,500 seeds.

S1 Feminized Hemp Seed for Growing

S1 seeds are the first selfed generation grown from the originally selected F1 phenotype.  Our Mountain Mango feminized hemp seed is grown using our original F1 female that we selected a couple years ago, we make our seed from the same living plant now as then.  It has proven to be a stable phenotype in the field, exhibiting consistent characteristics.  Our Quick Kush feminized hemp seed is an F1 phenotype from the same parents as Mountain Mango but exhibits an entirely different phenotype.

Our S1 Cherry Wine feminized hemp seed is produced from the F1 phenotype created by the breeder of Cherry Wine – “Bohdi”.  We make seed from the original living plant.  Many of the Cherry variety of hemp seeds for growing in the market are S2, S3, S4…. generations, not produced from the original F1, but from an S1 or other selfed generation of feminized hemp seed, not the original living F1 phenotype, which contributes to an unstable crop in the field.

Feminized Hemp Seed Cross-Pollination

We are one of the seed companies for hemp farming that produce our female hemp seed for growing under complete environmental control with our state-of-the-art indoor grow rooms in Colorado.  Indoor hemp plant grow rooms cost more to build as well as to power the lights and air-conditioning – but we make up for it in high-quality mature feminized hemp seed and peace of mind.  Besides the fact that we can pamper each hemp plant, we practically eliminate the possibility of cross-pollination, which can easily happen when feminized hemp seed is produced in a greenhouse or worse, a building with several hemp strains growing in it.

This has been a big problem for the medical and recreational cannabis industries, because every hemp farmer wants to have a crop of 100% female hemp plants that exhibit a consistent phenotype.  Cross-pollination results when pollen from ‘foreign’ sources fertilize the hemp seed stock females and produce male and female hemp seed of unknown parentage.  Trying to produce a 100% pure hemp strain seed in a greenhouse is risky and difficult because natural forces can bring in foreign pollen from miles away, be it from other hemp farmer’s crops, licensed and unlicensed cannabis grows or ‘ditch weed’.  We only grow our feminized hemp seed indoors, in environmentally controlled grow rooms.

Separate Indoor Grow Facilities for Each Female Hemp Strain

Cross-pollination is the reason female hemp seed sold as 100% feminized will have true males in the seed mix.  It’s scientifically impossible for feminized pollen and a female hemp plant to produce a male hemp seed.  A true male hemp plant is different from a female hemp plant showing ‘hermaphroditic’ characteristics.  Any female hemp plant grown from feminized hemp seed (or ‘regular’ hemp seed), can show male pollen sacs mixed among the female hemp flowers – if stressed enough during the growth cycle – but they are not true male hemp plants with  ‘y’ chromosomes, if seeds are produced they will all be female hemp seed or what we call feminized hemp seed .

Cheyenne Mountain Seed Company is totally committed to the hemp growing success of our hemp farmer’s crops. We make every effort and spare no expense to ensure that our hemp farmers are planting the purest Colorado hemp seed with the most consistent and stable phenotype replication.   We only offer three feminized hemp strains because we grow them in three totally separate facilities across Colorado Springs, one hemp strain per building, that way we prevent cross-pollination of our feminized hemp seed crops within our company’s facilities.

Evaluating CBD Hemp Strains​ for Growing

If someone looking to buy hemp seeds for growing asks, “What percentage of CBD will this hemp strain’s flower produce?”, they are asking the wrong question. This is a fact though: ​all hemp strains for growing CBD oil will test over the legal limit of 0.3% depending on growing conditions. Some of these growing conditions are:

  • Vegetation period
  • Number of days in flower before harvesting
  • Latitude and photoperiod
  • Ambient day and night temperatures
  • Nutrient program
  • Irrigation system
  • Idiosyncrasies peculiar to the hemp strain

​Because of the hemp regulations we work under, it makes a lot more sense to ask the question, “What percentage of CBD will this hemp strain’s flower produce when the legal level approaches 0.3%?”.  Unfortunately, an exact answer to that question is virtually impossible to predict. For tips and additional information, check out our resources for growing hemp plants.

Growing conditions listed above vary day-to-day and year-to-year. Historical test results, done at least weekly, over several hemp growing seasons at a particular location would begin to more accurately answer the question based on empirical data – but this industry is so new, data like that is very rare.
