Centennial Seeds was founded in August 2009 by with the aim of developing and producing high quality cannabis seeds for medical purposes.The founder saw the obvious need for reliable and well researched genetics in his local area. For some time previous to starting Centennial seeds he had been breeding and perfecting his seed production methods, early on recognising the value of preserving geographically isolated ‘landrace’ strains for use as breeding parents. This led to the creation of a private cannabis seed bank with over three hundred distinct genetic lines. Centennial Seeds’s library represents a fantastic body of genetic material spanning five continents. Its value lies in the wonderful variety of chemotypical and physical characteristics that nature has designed and evolved in Cannabis sativa, from high THC strains to those rich in CBD or with distinct growth patterns, smells, leave shapes etc . The distinct characteristics are many, and all deserve research.Centennial Seeds is proud to offer cannabinoid readings for strains where possible. They believe this should give buyers a better indication as to the potential of the genetics. All development testing and results given have been produced by FSL from dried material grown in Centennial Seeds’s facilities under standardized conditions.

I planted the Nepalese highland sativa back in August. That was 95 days ago and the plants, as i suspected, are enormous.

In the past I’ve grown seed from a nearby region in Nepal and the plants topped 15 feet indoors and spread 8 feet across the lower branches. I wanted to prepare for this possibility so I topped the plants aggressively and set them under a sheet of trellis fabric.

On October 11th I shortened the day length to 12 hours, down from 18. The plants are growing in 10 gallon Accelerator aerator pots in Fafard Organic Mix FOF-30 amended with dolomite lime. I’m feeding Jack’s 13-2-13 @ 140 PPM nitrogen and mono potassium phosphate @ 80 PPM phosphorus.

The plant’s branches have been woven through the trellis fabric in such a way that every growth tip has access to direct light. Over several weeks the weaving process continues until the canopy is relatively flat.

Once flowering is induced, the growth tips will begin to stretch toward the light. Deal with any stray branches that break out of the surface.

As you can see the lower branches and trunk are completely bare. The canopy above is so dense that very little light gets through. Any flowering sites below the canopy are removed. This redirects the plant’s energy resources to the canopy where they will be put to more efficient use.

At this point the plant extends 7 1/2 feet by 5 1/2 feet. That’s more than 40 square feet of surface area which is lit by two 1000W bulbs.

Since this is the first time I’ve grown this landrace I have no real way of knowing how long it will take for them to finish flowering. I’m going to guess and say it will be in the 12 – 15 week range.

The trick will be keeping them healthy and flowering until that day comes.
