RO water?? important?

i would say no. but there are others more experienced in hydro than i that might want to chime in. as far as i know that should be fine.

If your water tests soft around 100PPM. Then I would say no.

You can use RO water but with some products the PH will be lower than ideal. And the addition of calcium and magnesium will be a part of your routine with RO water.

Id only use RO water if it was necessary..
 
Wuts the target ppm w/ RO'd water? I havent done but one hydro plant in years, and the new veg plants are pissed at me....

Base water is ~15ppm after filter... how much is too much calmag? I am adamant about using it, and now worry perhaps the issue is I have too much for the plant size... (seedling/small veg plants)

And correct me if I am wrong, but I want to NOT use the organic calmag with my synth nutes DWC bucket? (got both around, GH org, and botanicare)
 
I live somewhere with 50ppms as well. Let me tell you why you want RO, especially for DWC.

You'll NEED to run an active microbe tea in your DWC to prevent something that lurks in virtually all tap sources: cyanobacteria. or "the slime". This isn't root rot. It thrives even in Chloramine/Chlorine/h202 enviroments once it gets a foot hold.

Check out Heizenberg's EWC Tea - Breeding Microbes Thread here on rollitup for a recipe and breakdown.

Anyway, you need RO filtration to remove the likely Chloramines added to your tap source. These agents will kill your beneficial bacteria and fungi before it has time to do anything. If you only have Chlorine in your tap source you can get by with aerating the water for 36-48 hours. But RO is totally recommended.

pH fluc's are a pain as well.
 
the lower your ppm when you begin, the more ppm of feed you can use. i've never needed to use cal-mag, though it seems a lot here use it like syrup on pancakes.
 
Hey im about to fill up two 50 gal res , to much water for my RO maker to keep up with so im gonna use tap. I bought some Dechlor and it removes Chorine and Chloramines the label says but it all so says it neutralizes heavy metals like zinc & Iron & copper and has a chealeting agent in it. will this be bad towards any nutes I had to the system ?
