Heres some advice from someone who uses tap water.
1. Use gallon jugs and fill them with water.
2. Leave the caps off for 2-3 days.
3. Cap them until you're ready to use them
4. Adjust the pH level of your water to hit between 5.5-6.5 for best results.
5. for soil i like to use the general hydroponics pH balance kit, it comes with a test vial, pH up and pH down and a pH test liquid with a color coded guide to balance pH. it's very useful for beginners.
6. Buy a humidity monitor to monitor the temps / humidity of the air , for best results temps need to be 75 degrees Fahrenheit when the lights are on / sun is out. and 65 degrees during dark time. 50 - 60% humidity seems to work pretty great. top the plant when its about 15-20 days old (Use the FIM method as it is easy for beginners) and experiment with Low Stress Training and Lollypopping as it gives great results.
7. Keep us posted, i hope this info helps.
