I have read that under 200 ppm before ferts are added is ok but that over 200 you need to condition the water. With 190 ppm pre-fertilization should I worry about reverse osmosis? Thanks. | ||

 | I use RO water because my water out of the tap is 300 to 550 ppm. I certainly would try to grow with your tap water first. If you have problems, then look at the water.

| Thanks. I am in a new location now and the water is almost 8 Ph and 190 ppm out of the tap. Been having a few nute lock out problems and just wanted to make sure. I was blessed in my last location. The water was less than 75 ppm and Ph of 5.9 out of the tap. | ||

| I may be misinformed but I've read that 150 PPM tap water will cause lock out. I always use RO water just to be safe and eliminate a possible problem before it happens. One less thing to worry about IMO. There is an RO dispenser a few blocks from my house...goes for twenty five cents per gal. Or better yet pick up an RO unit for your faucet at Lowe's or Home Depot.

| My ro filter connects to a water hose and I think it was 180. Not sure about the faucet ones as I need alot more water than they put out. What nutes are you using? GH has a line specific for hard water. I'd give that a go if I were you. I get lockouts on RO water if I'm feeding them too strong.

| 450 ppm tap water...so hard and heavy with iron, calcium and other minerals, it has a bouquet ffs....but...damn'd if it bothered the plants. [IMG]file:///C:/DOCUME%7E1/716/LOCALS%7E1/Temp/moz-screenshot-3.png[/IMG][IMG]file:///C:/DOCUME%7E1/716/LOCALS%7E1/Temp/moz-screenshot-4.png[/IMG]  A high PPM is not the matter...its the components and their respective ratios of that PPM that either promote or discourages growth and or nute lock out. | ||

| my tap comes out about 180ppm (hanna) 7.5-8.0pH, and i have an RO unit (for drinking water now, cant drink tap anymore). I was using nothing but RO water for plants, and the pH was harder to control (although i was also using different nutrients at the time too, GH maxigrow/maxibloom 1part nutrient, instead of the 3-part flora). Then i switched to half RO half tap to help try stabalizing the pH. The RO spits out 1 gallon per hour and has a 2 gallon tank, so it eventually over time just sort of got phased out for being used for plants. who wants to wait 2 hours for the tank to refill so you can refill another bucket? i'll use tap thanks  i've been using nothing but tap for a long time now and haven't had any problems. after mixing nutrients in with my tap, it always comes out 6.0pH (unless i use an insanely small or large amount) but i think it all depends what is in the water you are using. mine seems alright | ||
