Thanks I really appreciate itI run coco and have used a bunch of different nutrients. Im currently using MegaCrop and am mostly happy.. price is great and results have been good, they have a new formula which Im gonna check out when Im done with this stupid big ass bag (make sure you put it in multiple smaller containers if you go this route.. somehow I left my tote open one night and shit absorbed moisture and turned into a rock. I just made a stock solution and its actually more convenient but that's another day lol) Aside from the MC, GH cocotek is the other standout in terms of results. I began with AN like a bunch of noobs and got decent results but cocotek was better as well as cheaper.
I also personally have found drip clean and hydroguard to be beneficial.. there are a ton of different ways to skin a cat, others may prefer (or not use) any beneficial bacteria when growing with coco. I didn't use it for my first few years but a buddy recommended I use it now that Im reusing coco, which is another thing I would tell myself to do 5 years ago if I could lol.
Take things one step at a time and don't let the planning get in the way of getting the seed wet. Not to minimize the importance of planning, but there are some things that you can hold off on getting etc. Remember this is just a plant.. If you have any previous gardening experience or hort studies shit will come easy. A lot of us have a habbit of overthinking things and making them more complicated than they have to be.
Good luck brother! I cant wait to hear how awesome the first harvest is!
