some people get in a mind set ,that once they have had a good run of grows their way is the only way , what ever works for you is what people need to help polish,,, not suggest you do your grow the way they did theirs , i got advice like the op is talking about , i knew better due to the fact no one knows how bad my tap water is or how blistering hot it gets here in the summer , the key to this forum is to only use what applies to you or you think would benefit you with your setup ...good growing
