Use proper soil, newcomers. It's worth it to save you from the potential difficulties later in the grow. Use cleaner water if possible (tap water that sat out overnight to evaporate the chlorine). High salt content will cause the plant to lock out important nutrient intake. Stacking a few generic 5gal buckets from Lowes installed with fans, CFL lights, mylar, and a drainage tray is all that's necessary to begin fine-tuning this micro-climate.
