You can grow cannabis so many different ways, I wouldn’t really call one way the only way to grow it. With that said I avoid growing media with wood chips as it can cause issues with ph balance. I use brick coco that has been pre washed, then I buffer with cal mag and add in roughly 30% perlite. A lot of it is what works for you in your condition’s and what you like. Growing cannabis is as much a science as it is an art.Floraflex sells these quick fill bags that are a mix of pest and coco or coco and wood chips. In the past I mix my coco with a bit of perlite and hydroton. Is there a right or wrong way method or is each more a preference thing with how water flows and retains and what not ?
