Coco Coir
A few years back I had some bad luck with promix, got some bugs, fought them and won, and vowed to never let it happen again. Started growing in perlite because...no bugs...and I liked the idea that other than me bringing pests in, I was generally going to be pretty safe. My results were good, but it took me a long time to get good at keeping a low CEC environment, while also producing decent weed Recently switched to Coco and paid for what is marketed as a better brand of coco, some say the best(thats a little side joke) set up a res (needs to stay under 68F and aerated), automatic watering 8 times a day, but.....HOLY SHIT the growth rate is unreal! Thats all. Nothing novel here, just truly in awe to see the difference first hand.
