Yea i dont expect to run out anytime soon.. Its suggested to use 7ML and use "good" water but I have "good" tap water and my plants love it!! I just use 5ML I did use 7 before but 5 also works just fine.So I can make a crap load of bottles of this stuff as I have a 250 ml bottle of Atak. Rev, watts and transport... that is sweet
