Hi -- old man medical user here. After just three relatively successful grows in a room that can handle about 12 five-gallon ladies, the best advice I can offer others like me is to get yourself a rolling stool. When you're relaxed and comfortable tooling around your plants you want to spend more time with them! So you get to know them a lot better, see problems earlier, trim without haste, and enjoy marveling through a magnifying glass. I never really made a firm enough decision about whether or not to use real soil, but now I'm wanting to give a fully organic approach an honest try -- which can be pretty challenging in containers. Hopefully some of the more experienced indoor soil lovers won't mind sharing some of their wisdom. For starters I'd love to hear some best practices regarding homemade compost.
