I would check into that and find out exactly what's in your purified water. If it is like reverse osmosis, where all the metals and trace elements are stripped out, then you need to add CalMag or something to make up for it. Iron, zinc, all that stuff is important. I use well water just fine. Most people use city tap water just fine if they neutralize the chlorine either with drops or by letting it sit out for about 3 days so all the chlorine can evaporate.

I don't know what the difference is between distilled and purified. Try running it through a search engine.
Opie Yutts Reviewed by Opie Yutts on . aeroponic grow Hey everyone... I have learned so much from these message boards over the past few weeks, thanks to everyone for posting their knowledge. Attached are pictures of my aeroponic grow using an AeroGarden. I have been using the nute tablets that came with the system but I am going to change. These plants are exactly three weeks old. I have completed three outdoor grows, and this is my first indoor. These plants seem to be growing fast! This week I am purchasing a 400W MH w/ HPS conversion Rating: 5
