burp~~~ depends on what country your in whether you use 500 or 700 as it corresponds to countries nute measurements. In the us its one and in china another..Ill double check tomarrow but if I remember right in the us we use 500 which is EC 2.0 which is roughly 1200 ppms

Yes that is correcct in the U.S we use 500 and The U.K 700. I am just trying to better understand why the difference. So in general the U.K would just use a lower E.C than the U.S is it really that siimple? Why so many different scales i heard of some people that use x650.

Yup thats it..why do the european countries use metrics and in the US we use Standard?? Why Farenhiet over celcius??? Just to give us a hard time

Some nutes run a lot lower ppm but for different reasons.Like fox farm I bump up to 1550 ppm at its highest while some advance nutes will never hit 1000 at the high point.Differnt mixes and particle sizes

I am using Fox Farms Grow Big, Tiger Bloom, and Big Bloom. I am also using techna floras sugardaddy and epsom salts for hydro, and the same thing for soil but instead of sugardaddy i use Grandma's Molasses. I also occasionally will throw some zinc plated screws in my soil or hydro.

I run grow big,tiger bloom,big bloom,grotek super H202, and sweet in my aero grows..In my soil Im using only 6.8 ph water for the veg and now in the flower I added doses of indonesioa bat guano high phos,sugare daddy and molasses every other watering between sugar daddy..ohg and in my flood tables I grabed Dutch Master nutes to see if they were any good with grotek h20 and suagr daddy

I was thinking of trying something new as well i was thinking of advanced what would you reccomend? I was trying to go completely organic on this one but have come to find that almost impossible in hydro because of the ph up and down i cant get myself to use the unstable organic buffers.

I want to do a pure advance nutes grow and Im liking the looks of the Canna line but not sure yet.. I love my fox farm as it traets me good and is reasonable..The dutchmaster seems to be working good but Im not adding the potash mix but adding Tiger bloom instead. I hope the dutch ends well as Im doing my first BB grow in that stuff with my first flood sweet purple plants too and then one of my usualy plants tossed in for comparison from what I have seen fox farm do with that strain

Heres a little info I found a while back on converting ec/us to ppm.
Well I was going to post a link to the info but it looks like the site no longer exists
Anyway it's pretty easy, µS and ec are the same thing (some manufactures will list it one way or the other) you just add the decimal, all meters actually read the ec but then will display it @ different conversions (.5 or .7) or just the ec.. It just depends on what conversion your device converts @ if it's shown in ppm.
2.0ec @ a .5 conversion would be 1000 ppm
2.0ec @ a .7 conversion would be 1400 ppm (or so)
@ least this is my understanding but I could be wrong
