For you people that grow indoors "under the lights", how did you get started, and how did you learn what works and what doesn't? Is there a book out that tells you how to get started. I see instructions about growing such and such at ___degrees F. What if you have many different plants and they all have to be grown at various temperatures. I don't understand how you know what temperature you are growing them at. I know you need a fan for circulation, and a heater to keep the room at a specific temperature. Heat pads, timer. How do you know what supplies you ned for planting and where to order them from? I notice that people grow "under the lights" in less potting mix in less than 3 or 4 inches as recommended for WS outside. I would thnk with that method, you'd need to keep more detailed records.
