Yeah, I see so many tea recipes, and which is best? I don't wanna put any effort into a tea that is subpar at the end. I bought a bottle. Company say they took two year to get their recipe right. I don't have two years. I will research teas, while using this bottled stuff, and maybe by the time it's gone, I will have a recipe made. As a cook, I can't make a food recipe, and sell it after the first time. I have to tweak it, make it perfect. Then it can go on the menu.Seems pretty simple to make your own. Some people just use “veg” bat guano in veg and “bloom” guano in bloom. You could add other amendments depending on what yours soils got vs what your plants depleted. I think the only tricky part is getting the dilution right after it’s brewed.
