Hey guys, just a question about my medium. Could I (from seed) use a mix of coco coir and perlite at a 70/30 ratio amended with worm castings and Dr Earths all purpose 4-4-4? Would my plants get enough nutrition and minerals to survive with just PH'd H20 with the acception of the occasional top dress or compost tea? The plants are photoperiod and going to be grown under a Aokrean Cree COB LED 2000w in a 4x4. Is this light any good also?
