In our post about “Foraging for Wild Cannabis“, I showed some pictures of wild C. ruderalis plants I had found, and was lucky enough to find at the right time to gather a few seeds.

These smaller, harder wild seeds seemed adapted to the local climate, and made me wonder if the auto-flowering properties of this wild plant could be crossed with a more “bud-productive” commercial strain (I chose a personal favorite, “Double Gum”) to produce an early flowering plant suited to outdoor growing in northern climates that would produce significant buds. The ruderalis strain produced flowers, but they remained small and leafy, even in a controlled grow. They do have a wonderful orange/pepper aroma that I’d love to experience in a larger bud.

This strain of ruderalis seems to begin flowering around midsummer night (June 21st) rather than the autumnal equinox (Sept 21st), leaving the plant plenty of time to flower and spread seeds before frost can interrupt the life cycle. How I love this adaptable, wily little plant! Probably the escaped ancestor of hemp cultivation before prohibition of marijuana, life finds a way, and these fine-leaved, short plants pop up along roadsides, gravelly riverbeds, and vacant lots in parts of northern Europe.

I’m happy to report that pollinating a female Double Gum plant with flowers from a male C. ruderalis produced viable seeds that grew vigorously. (That’s the title photo above). Even more interesting is that the plant has grown far larger than any of the wild strain, yet has retained the slim leaves and lovely peppery-orange aroma of the father ruderalis. I’ll post updates as the buds develop – let’s see if mother Double Gum’s beautiful buds gene expresses itself over the next 6 weeks or so.

Here’s another peek at the plant – if you click for a full-sized view, you can see the fine clusters of white pistils that have developed in the last couple of weeks.

Make Your Own Autoflowering Seeds – Royal Queen Seeds “Royal Automatic” Autoflowering x White Label “Double Gum”

I’ve been curious as to what kind of plants we’ll get if we cross an autoflowering strain with one of my favorite standard plant, White Label’s “Double Gum” (see our earlier posts for Double Gum info).We had an extra “Royal Automatic” seed from Royal Queen Seeds that we started on a windowsill, just to see how it would turn out without extra lighting.

The plant flowered after about 3 1/2 weeks, and after flowering was underway for 2-3 weeks, I simply sprinkled the flowers with pollen from a male “Double Gum” plant using a dry paintbrush dipped into the pollen. It’s really easy to make your own seeds. Here’s a picture of the plant after about 5 weeks of flowering:

The plant is a mere 15 inches tall, due to the relatively meager light that it received during vegetation on a simple windowsill. These plants can grow quite a bit larger if you give ’em full sun, but we wanted just a small plant for trying out a homespun autoflower strain. I’m expecting that the offspring from this cross may not all be 100% autoflowering, but we’ll try them outdoors in the spring and see what happens.

Here’s a photo right before cutting the plant down to dry and harvest the seeds (about 8 weeks of flowering): Read More…
