Growing the BaOx and Otto II Hybrids ~ The Basics

April 15, 2017 by admin

The following are my methods. They have been developed over time and are reliable.

Planting outdoors: Seed can be sown directly by use of a seed drill or on smaller installations, by hand. Planting depth is 3/4″ in well prepared soil that drains well. If time permits, seed may be sown indoors under artificial light. A peat and perlite (peat-lite) potting mix in a 2 1/2″ x 10″ tree seedling pot produces an excellent rooted plug that can be transplanted directly to the soil. This indoor plug step allows you to pre-sex the plants before transplanting to the field.

Planting indoors: Seed should be started in a peat-lite potting mixture and transplanted into the same mixture into larger containers for vegetative growth and then flower. Planting depth is 3/4″ into moistened potting mix of approximately 60-70% peat and 30-40% perlite.

Fertilization outdoors: It is preferable to obtain an analysis of your soil before considering which fertilizers and how much to apply.

Fertilization indoors: I recommend Jack’s water soluble fertilizers applied at between 100-130PPM N and 50-65PPM P, depending on the stage of growth. An analysis of your water is the first step in determining an appropriate fertilizer for your greenhouse. From there it’s a simple few calculations to choose a base fertilizer mix and how to mix and apply it for best results. You can call me for more info. I highly recommend the Mammoth-P bacterial inoculant at every stage of growth.

Plant spacing: in outdoor installations I recommend a 5′ spacing in 5′ rows. That works out to 1,600 female plants per acre.

NoCo Hemp Festival 2017 ~ Will I be there?

March 30, 2017 by admin

Many people are asking me, “Hey, will you be at NoCo this week?” I’ve got to say no, but not because it isn’t a great thing they’re doing up there. I feel very strongly that it is a great thing; people meet, people learn, pure community-building stuff.

My problem is, as it always seems to be, it’s Spring and I’m slammed-busy.

Instead, like I have in past years, I’ll be meeting a bunch of people at the lab who are driving thru from the far-corners of the State – and much further – to attend the festival.

If you’re one of these people, please stop in a say hi. -Ben

Otto II Seed Is Back!

February 8, 2017 by admin

Last year I formed a partnership with a Colorado industrial hemp farmer to produce an Otto II seedlot for the 2017 planting season. That seedlot is harvested and undergoing testing in our lab. Once the seedlot has been proofed and germination tested it will be available for purchase.

This partnership accomplishes a major goal of mine, that is to produce seed at a much larger scale while maintaining high standards in performance and reliability. Producing more seed allows me to address larger customers growing on a “from seed” basis. This increase in production also allows me pricing flexibility that wasn’t possible when producing seed at the bench-scale.

If you’re planting industrial hemp for CBD production and you need seed, please consider the Otto II hybrid from Centennial Seeds.

BaOx Seed ~ Very Limited Availability

October 17, 2016 by admin

The 2016 hemp growing season is coming to a close and one thing we’ve learned for certain is that the BaOx high-CBD hybrid seed is our best performer ever.

If you are considering purchasing the BaOx seed for the upcoming planting season be aware that supply is very limited. Seed is available now, but not for long.

Mailing of Industrial Hemp Samples for Testing

October 7, 2016 by admin

Please do not mail industrial hemp samples to our lab. Twice now we have had samples seized by United States Postal Inspection Services. I have learned of these actions when I received notice by registered mail.

I have overlooked this in the past, but I am not willing to risk entanglements with the authorities. I hope you understand.

Mammoth P Microbial Inoculant

February 16, 2016 by admin

If you have been to my shop you know that I sell a select number of horticultural supplies. When I say “select” I mean very few. The reason for this is simple: I only sell products that I use in my lab in the seed making process. This means that you can buy these products from me knowing that I use them and that they work.

Today I added the Mammoth P Microbial Inoculant from Growcentia to my shelves.

mammMammoth P is an organically derived complex of beneficial phosphate solubilizing bacteria (PSB) suspended in solution. The product is mixed with water or a working-strength fertilizer solution and applied to the planting mix as a drench.

Mammoth P makes artificial potting mixes behave more like living soils and assists plants in nutrient uptake.

I have been growing in the same system for years and this is the first microbial amendment I have added to my plants. The results have been bigger, healthier and more lush plants.

Applying beneficial soil microbes to improve the performance of container grown crops is very cool science and is a safe and effective way to increase both the quality and yield of your harvests.

Mammoth P is a Colorado made product that I am proud to offer to my customers.
