for growing medical quality cannabis, stay away from inorganic products! HPK, Budda Bloom, and Stonington Super Soil are all that's needed for a successful indoor grow..60 days from seedling to harvest with this..and huge buds on 3' plants.after 30 days of building a strong, leafy plant, force flowering by changing light schedule to 13 hours off, 11 hours on. At this time, introduce (follow directions!) HPK and Budda Bloom every 3rd day. Back off products 10 days before harvest and chop in total darkness.. you can't miss!
