Lookin good Greenlivin, I havn't bought coco in a few years ,still have one package of canna coco The bricks come so you can separate them into 2 pieces if you want ,I like Canna because I can place the brick in an old cooler,mix up 5 gallon bucket of water/and double strength calmag ,so it doesn't try and steal it from the plant and dump it in leave it for a little while add perlite and your good to go , I run 8 plants per run in 3 gal pots (I feed 4 time a day) when I'm done I dump pots remove root material flush coco until ph is normal and ppm is close to zero,then I recharge the coco with calmag , I do use one new brick every year just cause it makes me feel better lol
