it seems the concensus is that growing in coco is the best medium, so with that said i am starting out collecting the tools to have a coco organic cab grow. i was unable to find a dummy's guide to coco set up and proper nutes to buy. i am looking to grow about 5 plants in my cab under a 400w CMH bulb. so one bag of the canna coco bricks? can someone please break down what i need to do and buy for this grow. thanx
