I've recently had some good results with a mix of sunleaves coco coir, perlite, and wormcastings. The proportions are probably like 40% coco coir, 30% perlite, 30% wormcastings. I also mixed in some rock phosphate, starter fertilizer, bat guano, and watered initially with seaweed extract. I germinated in the soil under a 200 watt CFL, and after about a week and a half added some Super Tea into the soil with some cal-mag and Superthrive. I added that stuff yestrday so I'm sont sure about the results yet.
