I originally planned to have a mom room, but after spec'ing everything out, I placed those ideas on the back burner (in a few years it will be 2 decades or so ago).
Then I realized the cannabis industry reflects certain quirks that exist in the fashion industry. Just as there are "cannabis breeders"--there are also "fashion designers"...each producing "new lines" of their wares several times each year.
In the fashion world new lines are released at fashion shows at New York, Paris, Barcelona, Milan, Rome, London, Los Angeles...and expect to pay about the average price of a new American car for a dress from this year's "new line". A few years later, that very same dress design will be available for a few thousand and hanging on racks at all the major department stores. And then about half a dozen or so years after being debuted in New York, the same dress design will be selling at Walmart for $100 or so. Hmmm, went from the price of a car to $100 in less than 10 years, how can this be? One word answer: Consumers.
Breeders release new lines each year and this year's "must have" seeds are impossible to find and when/if you do, it will cost you dearly. After a few years...those very same seeds are available everywhere; discounted too. And for some reason, the prices of the flowers sourced to those "hard to get" seeds seem to behave the same way. Prices start in the stratosphere and after a few years (when everyone else is growing the same strain) they steady decline until they are priced with "everything else" (price equalization).
Moral of the story: Running new lines every couple of years might be a good idea (fresh blood over old blood). Hence, my current genetics will probably be replaced in a few years...so concerns of potential genetic degeneration (which I have not experienced) is something that I don't worry about. But if I were planning to run my current genetics forever, then I would probably figure a way to have "mom rooms" at multiple locations.
