how much should i water it
Ideal water ph should be between 6.3 and 6.9, you may want to just go out and get distilled water because it will be 7.0 ph which is just fine. As for watering, just water it as you think you should, don't drench the plant because that will suffocate the roots. You should usually water every 2-3 days or when the soil is dry. You can tell if the soil is dry by pushing your finger into the soil about 2 inches. BE CAREFUL OF THE ROOTS! If the soil on the average feels dry, water it. If it is nice and moist, dont water it.
By the way distilled water is usually available at any cvs, walgreens, or grocery store.
