I have a fair amount of info and experience with Ken’s strains and Ken’s gdp in particular. I still have seeds from his original line when he was on hilltop in San Pablo… and that’s where I got the clone direct from Ken.
I met with Ken in 2009 to get the clone… it ended up having spider mites but I wanted this strain so bad that I went to battle with them and killed the mites after several months with various natural treatments.
I grew the clone for close to 10 years and kept it alive until I finally phased it out when I got the clone of cherry pie.
I never got any seeds from the indoor grows of gdp until maybe about 7 years in, I had a light leak and finally got some S1s. I also pulled some S1S seeds from an outdoor harvest.
Ken’s strains are pretty good, but I don’t think he made any of them. My understanding as I heard through the years was that he just took other strains and rebranded them as his own. Bay 11 was really good. Candyland as well, which was supposedly just GSC forum cut. I grew from seed his phantom cookies… and I had a really nice male phantom cookies that I pollinated the Ken’s gdp clone with… and I also pollinated the cherry pie clone with… And subsequently I got another male of cherry pie x phantom cookies that I pollinated the Ken’s gdp clone with as well for a 3 way cross… in fact, I just started germinating some seeds of cherry pie s1, Ken’s gdp s1, and gdp x PC x pie…
Here’s the deal with any seeds you grow… even when his gdp seeds first came out, it was really rare to get one that would be as good as the clone only cut. I don’t know what male he pollinated it with, but it wasn’t stabilized, so the phenos are all over… same thing with cherry pie… the clone only cut of cherry pie looked like it was going to pop seeds every time. It shows pollen sacks in the first few weeks of flower, but they never pollinate… I almost killed it before I read that fact and decided to keep it going on my first run.
Any seeds you buy from Ken, if they’re legit, are probably old for one, and pollinated with some random male he decided to use… your best bet is to grow some S1 seeds that someone has laying around and hope you get a good pheno. I’ve kept my seeds in the fridge forever, but they’re still a good several years old.
As far as the clone only Ken’s gdp… it was fantastic and it was not a small yielder as many people say. It grew like an indica… if you didn’t train it, it would grow as a big main cola (watch out for bud rot, it’s rock hard dense)… it would fade to purple naturally if you let it go 10 weeks/70 days and had the “purple” smell and taste… the clone had very distinct looking leaves… 3 long main leaves and 2 little ones below it… in fact, one of the main traits I noticed was many of them only had 4 leaves… 3 big ones, and one little stub leaf below it. They were long and spaced as well.
It was my favorite strain for a long period of my life… but honestly, I feel like it has its place in history, but there’s plenty of good similar strains these days to rival it and even be better than it… times were a little different back then and strains weren’t as good.
I made this account (I used to have one on the old overgrow that apparently doesn’t exist anymore) just to give you this info… You might be able to find my old threads on rollitup (sidewing Ken’s gdp) if you want to see some pics of it growing.
