Live Stoner Chat Advanced Nutrients and ppm

[fweedom]

Hey guys ive been under the impression if your going to use advanced nutrients for the ph perfect technology to work the starting ppm of my water should be 125-150.

Well i emailed advanced nutrients to see if it had to be exactly between 125-150 ppm and this is what they claim...




Me: I keep being told in order for advanced nutrients ph perfect technology to work my water has to have 125-150 ppm before i add any nutrients..is this true? Does the ppm have to be between 125-150 for the ph perfect technology to work properly? Thanks for the help.

Advanced Nutrients support: Not True. The ph perfect is actually best designed to work best in a water with 0ppm, such as reverse osmosis. Which is what we recommend if at all possible. If you have tapwater or filtered water, it should also be fine, but the general rule of thumb would be that a lower ppm is always going to more reliable/consistent.


Im just trying to determine what water i should use if i got AN, so has anyone used AN with water with 0ppm with success?

Also in theory is it really possible for the ph perfect to work best in water with 0 ppm? i would think that SOME ppm is necessary for it to automatically become 6.5 itself..or does that have nothing to do with ppm? thanks for any help.

Hi fweedom, I have used the AN nutes with both RO water as well as my well water (120-175ppm). The pH Perfect line has buffers in the nutes, so 0 ppm water will stabilize the solution easily, because the buffers in the mix have nothing else to bind to, so they work like a lab rat getting a tumor- it just happens. With my well water, I notice that the pH will still stabilize, but it can take a few hours, and even then it may be higher or lower than with RO water, as it is using the dissolved minerals (mainly calcium and magnesium) in the binding process. With my water, it works within my needed spec. Your mileage may vary, particularly if you are using tap or well water that has uncommon, or a LOT, of additional minerals and heavy metals. A bunch of folks here swear by rainwater. Where I live, rainwater is quite acidic, so I stay away... Hope that helps! Best to you.

That runs counter to what they were saying when they first released the pH Perfect. Without some added cal/mag there's a good chance of a cal/mag deficiency later in the grow.

Also, don't expect to see 6.5. 5.7 - 5.8 is what I get and that seems to be a pretty common number that I see others getting as well.

Thanks Fweedom. That's excellent information.

Wassup Muddy whats weird is ive seen your plants lately and they look perfect so it seems to work great under 125-150 like u recommend so who knows whats really the ideal starting ppm lol :dunno:


and really..5.8? i was thinking it would automatically make the water like 6.4-6.6 :Sharing One:

I've been using AN pH perfect GMB with RO water since my first grow yes Muddy is right, 5.7-5.9 is what mine always comes out at. I thought this seemed low too especially for soil but haven't had any pH issues after 3 grows now.

I use AN pH Perfect (TaNg's schedule) with store bought RO water that has a little baking soda and calmag added in. Not much as the ppm is only 25. I have never tested the pH of the feeding solution, but my plants are doing great heading into week 6. I have an Accurate 8 soil tester and my pots have all been around 6.5 to 6.7 whenever I test them (which isn't often). I figured if I was going to spend the money on the pH Perfect nutes I would just let them do their thing with no intervention on my part. If I go around testing everything, I would be too tempted to start adding stuff and trying to manage the pH myself. So far it has worked out great. I am treating it like my organic grows where I did not concern myself with the pH of the food, only the soil.

I love the PH perfect. I asked them about ro they said do not worry plain tap water will work fine. learn something new everyday I have well water and no problems.

My sideways picture grown with sensi ph perfect and hobby bundle that and a non woven grow bag. My outdoor blows away anyones indoor in my circle of friends. AN has allot to do with my sucsess IMO

Awesome guys thanks for all the info..it seems to work well in many different types of water from what im hearing from everyone..

Muddy has great results with 125-150 ppm, Andy's plants look perfect using water with 25 ppm, and people seem to have no issues using RO water with 0 ppm :dunno:

i did notice most people that use AN also add some cal-mag and if they don't they usually notice a cal-mag deficiency...but i did notice both the sensi grow and bloom contain both calcium and magnesium....Can anyone explain why cal-mag needs to be added so often when theres some already in the nutes? is it just not enough or what? :Sharing One:
