Totally agree! Great water for growing......PIA lugging heavy ass jugs around!Used it before I got a portable RO system. Worked great for me but was a pain in the but lugging water around town.
I don't do coco or hydro............sorry. Try the hydro forum my friend!Hey! What a great thread/journal. I have also wondered about my water. I had to buy a RO filter as the tap water was EC 0.45. I tried to switch to coco and was unsure about whether to add tap water to EC 0.2 or mono nutes, Ca to EC 0.2, then Mg to EC 0.4 then N (for veg) to EC 0.5 then the nutes. One person even told me to do both?
If I only add mono nutes, isn't EC 0.4 too high in Ca and Mg for my veg period if I'm on EC 0.8 - 1.0 ??I've gone back to soil in the meantime.
What shall I add ?? Please help !!! Thank you

I would be inclined to use the second one. It has much lower Na. The Nitrate seems a bit high, but probably manageable. I would use the second one as a starting point and then you can mix the 2 if you don't like what you are seeing. If you are doing soil, don't worry too much about pH. As long as you are using properly pH adjusted soils (usually well limed) you shouldn't have to worry about your pH.Im so glad your still answering post on here Mr. Ganja !! very interesting read. Can you answer this question please water guru !!?
Ive got two types of water i can use from two different stores, heres the mineral analysis (in mg/litre)
1)
Calcium = 52.18
Magnesium = 5.37
Potassium = 2.87
Sodium = 28.65
Bicarbonate = 162.0
Chloride = 16.53
Sulphate = 49.90
Nitrate = 3.78
pH = 7.93
2)
Calcium = 10.0
Magnesium = 2.5
Sodium = 9.0
potassium = 2.0
Bicarbonate = 25.0
Chloride = 12.0
Sulphate = 10.0
Nitrate = 11.0
pH = 6.2
The pH isnt that relevant because i got my pH up and down additives, but can you tell me if there is a type of water here that i really should avoid ?? Theyre both really different. Would it be best to mix them together 50:50 ??
Thanks !
Hey doc this has been one of the most informative thing I have read, not only here but the net as whole! Clear, concise and all in one spot!I don't do coco or hydro............sorry. Try the hydro forum my friend!
I like r/o because I can monitor precisely what I'm giving my plants. I saw a difference when I switched, but it was really out of necessity since my tapwater was over 600 ppm for most of the year.Hey doc this has been one of the most informative thing I have read, not only here but the net as whole!

I run hydro and this has been very useful, plants have the same relationship to water in all mediums.
I currently am doing a test with tap versus r/o, side by side and wil see if there are any benifets to the outcome in quantity. I have no issues really but have read that even if your plants look healthy, water issues can result in a loss of weight overall.
What do ya think will the r/o make a difference?
Thanks again
