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. 😂) 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. 😅
