Centennial Seeds 2015 Year In Review

December 3, 2015 by admin

The 2015 hemp growing season was a busy one, and one that none of us will soon forget.

As this year is coming to its end I find myself looking back at both the accomplishments and the lessons learned in 2015. This year was important to our business in many ways.

In January of this year we released the Otto II(TM) high-CBD seed variety to Colorado hemp farmers. Otto II was enthusiastically received by farmers throughout the state and stands today as our best-selling seed of all time. Farmers that grew the Otto II in its inaugural year reported excellent field performance and better-than-expected yields under a wide variety of conditions.

ottoII-1We are proud to say that in 2015 not a single farmer growing the Otto II seed under the industrial hemp program failed compliance testing by the Colorado Department of Agriculture. This is a powerful statement and one that speaks directly to the care and quality control that went into producing this new seed.

In August of this year we released a small amount of the BaOx hybrid seed. This was too late in the year to plant an outdoor crop, but just in time to cycle it at least once, maybe twice in greenhouses before spring planting. We will be paying close attention to the results of these indoor crops so as to better understand the harvest window for the BaOx.

This year we also began offering basic lab analytical services for hemp R&D, product formulation and crop compliance monitoring. Many of our seed customers utilize these services to monitor the THC limits in their industrial hemp fields and greenhouses and to develop accurate harvest window data for the hemp cultivars they farm.

While each of our lab services customers is different, they all have at least one thing in common: they need answers to technical questions related to their hemp agribusiness. We feel fortunate to be of service in this way to the industry and I personally take the responsibility of providing technical and analytical services very seriously.

While 2015 may be coming to a close, it is now time to start thinking about next year’s planting. Take time to think about what you learned this year and how you can apply those lessons to improve your outcome in 2016.

Thank you for your support this year. We look forward to working with you for many years to come.

Limited Release High-CBD BaOx Seed

July 30, 2015 by admin

Tomorrow, July 31st, I’ll be releasing a small amount of the BaOx hybrid seed. The BaOx(TM) is a new high-CBD seed that combines an inbred Hindu Kush line and the Otto male used to create the Otto II hybrid seed.

IMG_3116The BaOx is fast growing, vigorous, uniform in height and breeds true for the high-CBD chemotype. Very high CBD:THC ratios have been measured in the test plots.

I am releasing a small amount of seed, just 100 packs of 14 seeds each. The cost is $100. There has been a great deal of interest in this seed so expect it to go fast.

Thank you for your support. -Ben



BaOx: A new high-CBD hybrid seed from Centennial Seeds

July 1, 2015 by admin

Today begins final testing for a new high-CBD hybrid seed creation I call BaOx.


Pronounced “box”, BaOx is based on selections from an inbred-line of Hindu-Kush and the Otto II seed. The seed has been back-crossed and stabilized for high-CBD expression, fast flowering time and a short, dense structure.

Once testing is complete, the seed will be released for sale in Colorado. Stay tuned.


Otto II Seed update

May 29, 2015 by admin

I have a small amount of the Otto II seed available for purchase. I was holding this back until I knew how much of the seed I would be planting myself.

This will go quickly. -Ben

Muddy Start to the 2015 Hemp Planting Season

May 27, 2015 by admin

It’s no secret that we’ve had an extraordinarily wet spring season this year along parts of the Front Range. The heavy rains have impacted hemp farmers, preventing many of them from planting their fields.

IMG_2776The soil type on the farm I lease is a sandy loam over heavy clay. It generally drains well until it is saturated down to the underlying clay, at that point it becomes mud.

The mud is difficult to work in and easily becomes compacted under foot or equipment. With the soil in this condition it makes no sense to attempt to plant seeds or plugs.

So I wait. And each morning on my way to work I stop by and walk the field to gauge the moisture. I’m certain that one day soon the ground will absorb the excess and I can get on with planting my hemp projects.

My patience is propped up with the knowledge that at least one of my projects is moving forward in spite of field conditions.

IMG_2765 This project is a back-crossed generation of seed that will be used to construct a genomic map of the cannabis plant. This is the work of the Cannabis Genomic Research Initiative which operates from the Kane Laboratory at the University of Colorado at Boulder.

This step of the CGRI project requires a controlled planting of around 300 seedlings spaced 3 feet on center. These plants will be numbered, measured and planted. Later they will be sampled for leaf morphology, chemotype and genotype.

The seedlings for this project are growing indoors in an outbuilding on the farm property. They will be planted just as soon as the soil is dry enough.

Until then, I wait.



Otto II ~ High CBD Seed

January 23, 2015 by admin

The Otto seed line began in 2009 with an unknown seed sample given to me by Bob Winnicki, founder of Full Spectrum Labs.

This original material was highly variable, but it did contain a number of high CBD:THC ratio plants that became the early breeding parents of today’s Otto II(TM).


The Otto II is a hybrid high-CBD hemp seed developed in Colorado. Otto II is stable and breeds true for high-ratio CBD expression. Otto II is excellent for use in botanical extraction applications.

The plants are vigorous and can be quite large. Flowering is complete indoors at 70-77 days. Grown in sunlight along Colorado’s Front Range, flowers reach their peak resin content in late September to early October..

When Otto II is grown as industrial hemp we recommended that Δ9-THC levels are assayed 3 to 5 weeks prior to anticipated harvest to verify that the crop meets the statute for maximum delta9-THC levels. Testing is crucial during periods of unusually hot weather and drought conditions which may increase total Δ9-THC levels in hemp plants.

The Otto II seed is being released today and will be available for purchase while supplies last.

Otto II Release

January 21, 2015 by admin

Otto II will be released Friday January 23, 2015 at noon.

The seed is stable and breeds true for Type 3. Until it’s gone.
