Hey Bro. Just for general info EPA Max levels for tds is 500ppm. If you have municiple water that is extreamly high. I have well water it's at 560ppm, Had to start growing to find out I have been drinking crappy water all these years.tap water in my area is coming out at 500 ppm...and i have no idea of what that 500 ppm consists off..RO takes my water EC level to 0..now i know where i am starting at..and what i am starting with.then i add my nutes to the water bringing it up to the desired EC levels i am looking for..and that varies ..right now im feeding at 1100 to 1200 ppm..and i know what the plants are getting...you can if you want bump up the PPM untill the edges of your leaf's start curling then back off..i dont do that..but that will give you max growth rates if you do it..on the rest of your plants..clones ect..of a certain genetic type...you will know then the max you can feed it to get max growth.
Naw, the RO store bought water doesn't bounce much. I've given up on the home brew and am shelling out for the Eliminator RO system today... found it for 176.50, best deal i could find. You can imagine how many problems i was having trying to keep my plants healthy before i got my pH and TDS meterHoly SHIT! You have some seriously hard water, and it's not just the bicarbonate. Damn, your teeth and bones must be strong. I bet if you took that water and threw in some gravel and sand you'd have concrete. Jesus H. "Jumpin'" Christ! I wonder what the nitrate and other solubles are at.
Are you getting the bounce with the R/O water? If so then I'd consider an aquarium product to buffer it down, or just filter through peat moss or soak the peat with an airstone with the water you wish to use. Test that, mix it with R/O or tap water as needed, but know that the water out of the tap has strong buffer fu.
i use half tap,half RO....works fine, i dont think you can buy it off the shelf in a normal store tho...only hydro shops?
dam you gotta a big grow?Ill juss buy me a small ro system..I onlyu need a couple gallons everyn other day....rite now im usinh my tap water..hopefully its not too bad..im using alasdka fihsfert & maxicop to foliar feed...what's that? the RO system? you can buy them at Home Depot i know... but their 'biggest' system can only handle like 10 gallons a day... whereas the Eliminator says it can do 100 gallons a day. but 150.00 plus shipping isn't too bad, off ebay. i'm guessing i'll need 50 gallons every other day or every third day, so the 10 gallons a day wouldn't cut it, plus it actually costs more than the new one i found on ebay.
