You cannot tell an individual, that has grown and experienced certain positive results using superthrive, that it does not work.

Now one more thing I would like to say about this subject.

You are all dedicated growers...taking the utmost care to grow the ultimate plant. Therefore, Regardless of what you use, You will have positive results...It's called 'KARMA'

I gotta go tend the garden lw
