I'm toying with the idea of making a small-ish grow closet. I've never tried this before, but from what I understand I'll need the following: 1. Seeds 2. Soil 3. Fluorescent light (not the best but something I hae access to) 4. A cabinet 5. A fan / something to mask the smell / ventilation holes 6. Additional nutrients If I have all that, what do I do next? Do I cycle the light (12 hours of light with 12 hours of darkness?) to simulate the natural cycle? Do I just put the lights at the top (not too far from the plants)?
