I'm planning on using royalmix and mix in some bat guano, as it say it takes 4 weeks to break down in soil so it would be available for flowering. I was planning on using only water for the entire grow. Do you think the plant would have enough nutes and still give a high yield? Royalmix claims to have enough nuts for 6 weeks! I would have lightmix in the middle to allow the seedling to grow first.
