That's a good article, thanks. I am still reading it, but it does reinforce some of the opinions I have thus far about fog. First off, the method I am using at the stage I am in the grow, many people use as a separate cloning machine. I have read dozens of grow logs where people have set up cloning machines to populate their gardens and they use single chamber fog systems to do it. Much further in the process then I appear to be now, these machines work flawlessly. Where many people disagree about fog is in the later stages of development, but I have that covered. My problems are likely to do with the water source. I have from day one used water that was 225 to 250 and from there have added various levels of nutes. I need to get drastic and come up with another water source.
