hello there Ive just measured my tap water with a EC meter and it reads 0.4 i found a site that converts EC to ppm and it says its 280 in a book i have it recommends getting a reverse osmosis machine if the water is over 300 ppm do you think i will be alright with out one for now? have a look at my grow journal to get an idea of my set up Ive spent a lot of money making sure no environmental factors are over looked and i don't want this to effect me to much.

thanks for any help i will no doubt receive you guys are very helpful and your advice is priceless!
 
I vote that you get an RO system... theres no security like knowing for sure. Tap 280 isn't horrible. It's whats in that 280ppm that can be bad. City water contains everything from chlorine to flouride, salts, calcium, rust etc.

they way I figure... if I want my girls to have that stuff... I'll give it to them. I;m going through great lengths to make sure they get the optimum, why leave water to chance.
