I use Botanicare coco with good success. I like the big bricks, easy to stock up on and store. And 1 brick makes 15+ gallons of coco.
Welcome to the brotherhood! Hope you have a tall 3 x 3 or larger!! Yeah! Huge ass plants! Are you going to run coco? If you do , I'd suggest a bagged product of canna coco or Black Magic(home depot) to start out with! Ph to 5.8 and you are golden!![]()
