Just harvested mine yesterday. I made a fair few seeds, but honestly, I dont think its worth it if you have other seeds to use. As it is Pretty poor yeilder and average smoke for how long it takes.

I'm not aware of any commercially available crosses with this.

This happens to be one where I think you may be better off leaving it as it is. (IE cross with itself for more seeds, or not at all).

This particular strain is known for an exceptionally long flowering time and low yield. You put up with these things for the wonderful sativa-like high quality you're supposed to get at the end and that's really the main point of the strain.

If you crossed it out with an indica, you could certainly improve the yield and reduce flowering time, but if you did that, I just think you'd probably lose the high, sort of defeating the purpose of the exercise.

I think if you were interested in crossing with this, it would probably make the most sense to try and cross this one with another landrace sativa or haze, maybe in an attempt to tweak the flavor or bud density.

your on the right path. i have reversed my landrace durban poison going to dust dr grinspoon, forum cut, luis xiii, mk ultra, platinum bubba, 3x crazy and to my blueberry widow x platinum og.

... i was thinking if i crossed the durban with the grinspoon and took the shortest flowering best all around new phenotype that would produce my pure breeding sativa... wich i then could take to my pure indicas and look for some hybrid vigor!

Well, if the parent Durban is good, I'd think at least some of these crosses will make interesting offspring.

In particular think backcrossing the "forum cut" (by that you mean girlscout cookies forum cut?) to Durban poison could be interesting, since that's allegedly a parent, so you might be able to generate more GSC-like phenos than say a self-cross that way.


I think its not that simple.

Assuming your Durban and Grinspoon are both inbred lines (and I think they are supposed to be), crossing them would create an F1 hybrid Durban-Grinspoon.

The plants should all be fairly similar, and they would be expected to have similar (if not absolutely identical) flowering times. They also should have "hybrid vigor" since you're crossing two separate inbred lines. At the same time, they would most definitely NOT be "pure breeding". If you cross two of these F1s into an F2, you'd expect to see the full spectrum of phenos from nearly Durban-like to nearly Grinspoon-like with every possible mish-mash in between.

If you really want this cross to be "pure breeding" (aka "true breeding" aka "inbred") you'll have to cross the F1s into an F2, do selections for the specific traits you wanted to isolate from each parent (including short flowering time, if that's what you're after), recross into an F3 and repeat until you had an F6 or so. With potential 10-16 week flowering hybrids, especially at first, you'd need to grow from ceed, this is a potential 3 year project.

IMO, this type of breeding program simply isn't for the amateur, since it requires a multi-year commitment to do it right, and a dedicated space to grow out not less than 20 plants at once to do selections from (and 50 is better). Do it half-assed and you probably won't end up with anything better than what you started with.

Also, trying to reduce the flowering time of Dr. Grinspoon may be a mistake. . .the unique high quality is probably directly related to the flowering time, and you may well lose it by paring down the flowering time.

If your going to be a breeder, you have to smoke the product yourself, and make your own decisions.

And yes that involves taking the time to hold and go through clones. As well as getting burned sometimes by making seeds that just aren't what you want.

Jogro said:

Absolutely.

I'd go so far as to say that if you want to be a breeder, then almost by definition you MUST generate a LOT of ceeds that aren't what you're after.

That's why you do selection. If you aren't doing selection, you're probably not a "breeder" but just a "crosser" (aka "pollen chucker") or "seed maker".

In terms of making selection decisions, how you do it depends a little bit on what exactly you're trying to accomplish in your particular project. Certainly smoking the product is the time-honored way of testing/selecting drug strains, but it may not be the "only" way.

For example, if you're breeding for research or industry, the goal of your project may be to create stable strains that put out exact cannabinoid ratios, or maybe high levels of specific terpenes. In cases like this lab testing is probably a more appropriate way of doing the selection in question.

Durban Poison is a myth. You want a real landrace sativa, I will bless you with the best Swaziland has to offer. Or the Transkei, or Valley Of A Thousand Hills.

The Durban Poison on the market is definitely not a pure African strain. Grown it out, looks alien to me, definitely not from HERE. I've been hunting the mythical 'Durban' weed for 16 years. All I know is EVERYTHING from Durbz is SHIT. Okes up there don't even take the pips out so they don't care about quality... I think somebody had some good Swazi while in Durban, it's the closest landrace that can be found near Durban, and if you get the good one, it's DANK. STRONG pepper taste, knocks you so hard your grandma feels it.

Very rare now, it's on the way to extinction. Fucking Dutch breeders have been using the relaxed atmosphere and tribal land to breed their skunks and test them. Our landraces are being contaminated.

If anybody wants some beans, I will not only gladly help, but be eternally grateful. We need to protect this heritage.

u prolly dont have to dust her if u want seeds, they'll hermi on u hehe not necessarily... but I think I might have a successful cross with mine, u can checkout my grow, it's The GreenSanta Grow in the Led sub section of RIU. I crossed mine with spacebomb (accidentally... or on purpose can't remember)

The seed fell off my DR.G that was the closest to the pictures u see on google ( I grew 2 of them and one had normal big buds, the other had the towers ) The plant also took 3 weeks longer than the other. I wasnt sure whether to grow or not to grow the volunteer, but I couldnt resist. It turned out it must have been crossed with my spacebomb pollen coze that baby flowered in less than 2 months (as opposed to 4 months for her mother...) and the buds were exactly like the one u see on google. Anyway, I revegged the plant and I am currently flowering it again, hoping she won't hermie and I got myself a killer Keeper!!


EDIT

Send good Vibes please, this might be a keeper for a lifetime in my garden if she doesnt hermi after the revegged. I did harvest her a bit early (around day 45-50) the first time but she had no nanners whatsoever... so I can't wait to grow her to the end!!
