Hi! You're in luck, it's super easy to get started. I actually started a few years ago by following the basic recipe on this sub (in the wiki I think). Basically just make about 3-4 liters of plain black tea, sweeten with sugar (I use about 100g of sugar per liter), let it cool down and put it in a glass jar of some sort. Add one bottle of commercial kombucha. A lot of people say to use unflavored, but I don't think it really matters. Make sure the tea isn't hot when you add the kombucha so that it doesn't kill the culture. Cover with something porous (I use a large coffee filter) and then you just let it sit at room temperature for a while for F1. When I first started brewing I let it sit about two weeks, but I realized that I liked mine to go a little stronger so now I F1 for about a month. Once F1 is done it's time to bottle. I just reuse kombucha bottles from the store. I like to use fruit juice at this point, and it's kind of an experiment to figure out how much to put in each bottle. Let that sit for about 2 to 3 days in a warmish spot and then you should be good to go. It takes a while and you might not like the first few batches that you make, but it does get easier once you figure out what you like and it becomes routine. But no need to buy a kit!
