You’ll find a lot of kush in the progeny, but the chocolate usually doesn’t carry through as often.
My Swackhammer, The Orbiter, Suga Suga all have easy to find knock-out phenos. (I have some swackhammer, the other two you’ll have to find or make trades.)
I actually have a worked strain, that I’m still working that might be rightttt up your alley. The only thing is that I have not released any yet and I’m not sure if I will. (I might hold this stock and only release the end cultivar.) If you want to run them I’ll share a pack if you’d be willing to document them. I won’t tell you what the strain is yet though. But if you need a sleep aid and pain killer this should do the trick.
