Water & Humidity  

Water is a key ingredient to any grow setup, whether it's the water used in your hydroponic system, the water you feed your plants, or the water in the air.

When watering your plants, always be sure to let water sit for 24 hours to allow it to reach room temperature and to remove chlorine or other additives.
