Is there any way to get Herm genetics out of a strand?

    You can sometimes but it takes many generations of breeding to the ones that don’t herm to fix it.
    You will spend a lot of time flowering and re vegging plants to get it done so the strain better be worth the time and money spent on it.

    Run a bunch of seeds. Take lots of clones. Then start a regular grow to eliminate the obvious herm prone females. Now start stressing the survivors. Cold water, high nutrient levels, interrupted dark cycle, physical damage and other stressors. Now select the survivors from that. I would try reversing the selected female/s and self pollinating or cross pollinating depending on number of survivors or depending on desired traits. Then you would want to repeat the process with the new seeds to be sure. Lots of work. Better to start with hearty genetics plus the male lineage is harder to see the outcome before growing out the progeny. Male selection is by far the trickiest part of any breeding project and often why breeders will make many crosses using the same male.

      Awesome thanks! Sounds like about a year or more worth of work, but I’m sure its worth it lol

    In my opinion there’s no real reason to try to stabilize something thats clearly herming. It would take so much time and work to breed the intersex traits out, You are better off starting a with fresh genetics that dont herm and making something new instead.

    If you are going to put in YEARS of breeding work, why do it with a crappy strain thats herming? You could apply that same level of time and effort to improving a non-herming strain and you’d make something even better.

    The only real reason I can think of for putting in the effort to breed out the herming would be if you are working with unique landraces. If you REALLY want to work a wild grown plant with herming traits into something commercial viable, this would be the way to do it. You are still looking at a crap ton of work over several years, but at least then you are putting in that work to create something new and unique.

    Putting that level of effort into stabilizing an already available hybrid definitely isn’t worth the effort.
