PLEASE HELP! HOW IMPORTANT IS RO WATER?

[btownbuddah]

My tap water is 40 ppm. How big a difference is it going to make if I buy a reverse osmosis water purifier? Someone at the hydro store told me I don't need one. I'm about to start flowering and I'm willing to buy one if its gonna make a noticable difference. I would appreciate any thoughts. I have a 4X4 flood tray with 1000W Thanks :rasta:

That's a pretty low ppm for your tap water. I'd say you wouldn't need RO water.

RO is not necessary, BUT, it removes the chlorine ... chlorine won't harm your plants, but it does kill the beneficial bacteria ... so, if using chlorinated tapwater, don't waste your money on microbial additives (Big Bloom, Tarantula, etc. etc.), they'll be killed as soon as they hit the water ... leave the water uncovered for a couple days, so the chlorine will have time to evaporate, then you can use additives, if you choose ... :smokin:

You should not need RO with that tap water, but you MAY need calmag. Monitor closely for any sign of Ca/Mg deficiencies.

RO won't get you better ppm than 40 or so on average. But I think you DEFINATELY need CalMag. No less than a teaspoon a gallon.

what colour is the inside of your kettle?
do you get any scum from the water,like on the inside of your cup?

might want to check your filters ... my RO unit ($175 on sale) brings tapwater down to .002 ppm ... perhaps yours needs a filter change ?? ... 'normal' CalMag+ dosage is 10ml, or two teaspoons, per gallon ... :smokin:

Thanks everyone. In response to dotbong I don't see scum on any of my dishes. I guess I'll just go without the RO for now. I didn't think I would need CalMag because I use Supernatural nutes which has a lot of that already. But I guess I won't know for a couple of days. They look very healthy now but they're still vegging so I'll have to keep a close watch as they start to flower.
Today I have to go buy an AC unit. I didn't think I'd need one for another month but it got really hot all of a sudden. Anybody have any input on whether I should keep on the fan which brings in fresh air or just recirculate with the AC and keep the CO2 flowing? If I stopped bringing in the fresh air to the room I would run outside air through my hood and back outside. And I would have to find a new way to install my carbon filter. I probably should have started a new post for this. But I would still appreciate any input you guys and girls might have.
:jointsmile:Thanks again

If you are running CO2 you should search for user 'tranoble' and read up on something called 'sealed room technique'.
