Feminized Hemp Seed

Bred for Medicine Growers

Producing High Quality Medicine

Cheyenne Mountain Seed Company’s Feminized Hemp Seed

​If someone looking to buy hemp seeds for growing asks, “What percentage of medicine will this strain’s flower produce?”, they are asking the wrong question. This is a fact though: ​all high medicine strains 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 strain

​Because of the regulations we work under, it makes a lot more sense to ask the question, “What percentage of medicine will this 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 feminized hemp.

Growing conditions listed above vary day-to-day and year-to-year. Historical test results, done at least weekly, over several 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.

What Makes Our Feminized Hemp Seed Different

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

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

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

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