No, not all. I'm just saying that microbes are all around us and will compete with
each other for battleground space so you likely don't need special ones from someplace else that likely won't make it long term in your environment anyway. Like
@Gee64 I get most of mine from my worm bin and I didn't put any in there to start. Well, I probably did when I started it with wild caught worms. I'm sure some hitchhiked a ride on/in the worms themselves.
Think of how we make LAB (not that you'd know
) . We put out a carbohydrate liquid in the open air and the various microbes in your environment populate it. Then we isolate the ones we want by oversaturating our collection liquid with milk so that the ones we want are happy and outcompete everything else. We don't need to buy those microbes as they're all floating around in the air. But only the ones that have adapted to your conditions. Those that thrive in the arctic won't last very long where you are, nor would those around you do very well, or last very long, in say, a desert environment.
It's more like 10.5 hours of darkness that's the actual number. Most of us use 12 just to be safe, so you won't be triggering any move toward flower with anything north of that.
Try Supercropping the branch stem just a tad away from the joint. That will relieve a bunch of pressure right at the joint itself. It will also give you a "knuckle" which is supposed to increase the flow of water and nutrients to the colas at the end of the line. Win/win.
