theres a creek and running water, since its not stagnic (is that the word?) in one area would it be safe to get the water from there?
A creek is fine if it is clean and hopefully spring fed. If you have a ph & tds tester, you can check it. If you don't, sometimes you have to use whats at hand. And I'm sure you were joking about 3 times a day. I've used creek water many times. Good luck with your grow.
* stagnant* well, im thinking you can just bring an extra container to get stream water. or you could bring gallon jugs full of water and hide them in the trees by pullying them high up with rope. you wont need more than 1 gallon per 7 plants anyway untill they get bigger. so u could bring like 3 or 4 gallon jugs
