I had two separate bags that had multiple flushes each (one did 4, the other 5!) and instead of retiring them, I decided to bust 'em up, combine 'em, rehydrate the resulting mix, and spread it out in one of my bins. Needless to say, it wasn't ready to give up yet...
If I take a pen and a piece of paper, and I place the pentip to that page the ink will bleed and we will have... A dot. To us, it is just that: a dot. For the pen has been lifted away and placed elsewhere, perhaps, to write a new line. But to the page? To the page, that dot is the very definition of "a pen," as that single point is the only point at which it has experienced a pen, the only place in which the two have met. To us, a dot. The impression of a pen, the mark it has left. To the page, a pen.
I am the dot.
Best of luck on your journey! I find the pre-made grow bags to be super reliable, personally, so long as 1) you know your syringe is clean, and 2) you stick to some very basic rules for cleanliness.
Though they do tend to yield... A lot. I tried (and failed) a fair few different methods (Uncle Ben's was the worst for me, but it gets a lot of praise widely -- and that's for good reason! My luck is just... Contrary. ๐) and eventually I settled on bags... I inoculated 3, because I was anticipating more failure... Instead I got 3-4 amazing flushes out of each, and I don't know what to do with all the fruits of my labor. ๐
