Some people use distilled water, others don't. It really depends on the quality of water in your area... do you have a PPM meter? If not, it's a good thing to get from the hydro store. They aren't cheap but it measures how many parts per million are in the water. If your tap water is over 400, it's probably time to use distilled water instead. If not, you are fine. The PPM meter also helps you to know how much of your nutes you added to the water. Pretty handy tool
razzapiggy Reviewed by razzapiggy on . Grow Log #1 - Shiva Skunk - Help is appreciated! I just put two Shiva Skunk seeds in some moist paper towels and tucked them away. I'll wait a couple days before checking. About my setup I have nine CFL Cool White Lights (75watt equiv. / each; 675watt equiv. / total). Not sure about lumens. My grow area with 2x2x4. The frame was built from 1" Schedule 40 PVC. Inside, the walls are painted Flat White. Also, using Distilled Water. Not sure on my Soil just yet. Any suggestions would be awesome! Rating: 5
