I searched for this lots of results, but not this exactly.

I emailed the manufacturer a couple days ago and I find that if they don't respond in 24 hours, it aint happening.

Here is the question

There is a FAQ on your site says you should not use distilled/RO for rehydration. You recommend using GoFerm. Is it optimal then to add GoFerm to RO/distilled to get the correct level of nutrients? I guess my real question is what water did you use in your testing to arrive at the formula and dosage rate recommended for GoFerm? Thank you.

Anyone have any advice on this?
