Anyone wana take the 'Evian Challange' with me?

I decided a few days ago to use Volvic natural mineral water. I don`t know if its a coincidence or not but i have seen a difference in all plants ... ranging from 4 weeks up to 10 weeks. I use Biobizz products and fish, blood and bone as well as molasses so for what its worth, i do see a difference

Thankyou very much dude, i cant remember the chemical composition of Volvic but at least someone else noticing the benefits of mineral water over their tap water, my guess is a cal/mag supplement in with your usual water would get you back on track again. It seems to me to be the cal/mag in the mineral water that the plants love the most and those in soft water areas will certainly notice the difference.

Thanks for taking the mineral water challenge dude and proving to everyone mineral water is safe. Peace

For a *simple* solution to cal/mag problems in soil, Evian seems a long and expensive way around.

*Simple* for me is spending $5 for a 40lb bag of dolomite lime, adding that to my mix and taking care of any cal/mag OR pH issues for pennies and using tap water.

Why complicate something simple and waste $$$$ at the same time?

Dolomite lime don't cut it for cal/mag in soft water areas, or at least thats my experience dude.

The idea of the Evian would be to diagnose cal/mag problems, not like gona use it the whole grow i was just very intrested in the cal/mag properties of mineral water especially Evian.

Please understand cal/mag supplements would be better but wouldn't it be good to know Evian did the same thing?

How did the volvic work out? No problems i trust dude?

No matter how much dolomite lime or egg shells i add to my soil i still need the cal/mag in the water.

Not trying to complicate things whatsoever, trying to make things easier.

Imagine someone thought they had cal/mag deficiency! Go grab a bottle of Evian and use that instead of your tap water. If it works then go buy exspensive cal/mag supplements, Simple!!!

Just cause you guys prefer cal/mag supplements or got good water don't knock me for trying to experiment a bit and help growers appreciate cal/mag in all its glory.

God, if another person says dont bother with mineral water i am gona give you a lecture, really rollitup, really! If the hospital werent full of nute problems and cal/mag i honestly wouldn't bother but as it is i would think i was at least smart for finding other options.

Once again Evian is liquid cal/mag as per the ingredients, wish everyone who had cal/mag problems was a pro grower with a big bottle of cal/mag supplements but as per the hospital threads they obviously aren't, maybe you guys should buy everyone some cal/mag supplements from Hesi nutes as it would certainly save me time looking into cal/mag but i suspect you dont want to!

Oh well on with the mineral water, knowledge is a good thing so i am meant to believe. Peace

Some growers will try to describe cal/mag deficiencies but i find this chart easier. Calcium on the right and magnesium deficiency on the left. If your leaves look like this you most likely got cal/mag troubles. Peace

Then what do the *straight* gardeners/farmers do in your 'soft water area'? I'm sure they neither use bottled cal/mag or Evian in their gardens or fields.

I don't have the same experience and my local water, from mountain lakes, is >50PPM, pretty soft. pH is ~7.1.

But, experiment on, the whole purpose is experience and knowledge.

God knows what the gardeners in my area do, i know they don't use biobizz and get better results from more complete fertilizers. As for the farmers calcium is directly corelated to crop yeild as well as cation exchange capacity and pH. They use age old equations depending on the cec and pH to work out the lime and calcium requirements, most fields are required to be limed in advance once every three years and for some can even be the difference between sucess and failure, farmers take calcium a lot more serious than pot growers imo.

My water is below 50ppm also, i would probably sumarise that a better fertilizer, one that contains adequate cal/mag , is needed for my grow and would prevent such problems. This will certainly be my next thread when i finish this one.

Outdoors a plant can find cal mag very easily, in doors with soft water it is much harder, relying on lime and seaweed is simply not enough for my cal/mag hungry plants and to be perfectly honest i couldnt grow a tomato in my soil and water without extra cal/mag, the seedlings show the biggest difference, more than weed but all is good with the Evian.

Thanks dude as i love to experiment, especially if it leads to bigger yeilds and less cal/mag problems for everyone. Peace

So anyone know approximatly perfect levels in ppm for calcium and magnesium per litre/gallon of water for good growth of a marijuana plant?

I know strains may vary a little or a lot but there must be some recomended levels in ppm for cal and mag, there probably some for iron, sulphur etc etc too so chime in if anyone knows or for any of the 13 or so nutrients? Peace

Ok so i'm probably just talking to myself but now i have focused on the bicarbonate levels of water. Seems like below 220ppm is fine but Evian has a bicarbonate level of 360!

So on understanding bicarbonates i know they are responsible for raising the alkalinity of soil and water thus possibly locking out iron in crops over time. I know adding acid to pH down the solution will neutralise or balance the bicarbonates and hence not make soil alkaline. I also know that bicarbonates can build up in soil but fail to actually understand if just pH'ing the water to suit marijuana will take care of bicarbonates and stop problems occuring.

Hmm, i wonder about bicarbonates in water, probably going to scientific for most here on rollitup but i seem to know most things about water until i get to bicarbonates.

Reverse osmosis take the bicarbonates out i think and hence its inability to buffer at any one pH and the wild pH swings. Adding cal/mag may also increase the bicarbonate levels as they seem directly correlated to each other.

Any water scientist's in the house?

Or you could just use tap water and some extra Cal-Mag. What kind of retard would put expensive bottled water on a weed plant?

One that takes his time to fully understand cal/mag before just taking the easy route and buying some exspensive branded cal.mag.

Most growers would do anything for a quick fix and personally i feel there may be a nute company out there that dose some ferts with good levels of cal/mag that would mean i dont need an additive and hence save money and time in the long run.

You may call me a retard but i sir think it is the opposite way round and being retarded would be not looking into all aspects of water and ferts. You can keep your cal/mag supplements, i'm sure the company appreciate your money for like a few cents worth of elemental cal/mag, i however dont want to be so dumb!

Please read the whole thread retard! I am not saying use Mineral water for growing weed!!!! I am asking what are the benifits of water with good levels of cal/mag in!!!!! Just so happens Evian is a water with good levels of cal/mag and my soft tap water isn't!

Give me a break dudes, trying to work out the cal/mag principles here not recomend growing with mineral water.

Sorry you lot are so cheap, mineral water is not exspensive to me, i open my wallet and take out a few coins and i have 9 litres of grade 'A' water, sorry you think you need a bank loan for some mineral water, acting like you from a third world country or somthing. If times are so hard cancel your internet provider because you obviously need the extra money and would benifit from less time on here insulting me.

Weed growers seem to take everything for granted, just add cal/mag supplement, just up the ferts, just do this, just do that! Get a life i aint that thick, schools in but you obviously missed the bell and are still flicking marbles on the playground whilst the rest of us got our heads in books.

Please do not call me out on mineral water, once again i am not recomendidng growing with it but merely looking at the correlation between cal/mag and plants, Evian works perfectly but had there been another way other than supplements i would have recomended that, some say use lime but that seems not to supplement my soft water enough! Really tired of growers who think they know best, each to their own and allbeit for me to try and understand somthing.

Anyone else wana say the same old boring thing and learn nothing pM stomata he got the best advice going apparently, just dont worryu if he calls you a retard, seems perfectly normal for some people to insult others!

Cool story bro.

I have a 35 gallon garbage can I fill with tap water at least once a week. I don't think I could afford any source other than tap.

Yer it is not suitable for every grower, my tap water is too soft, closer to Reverse Osmosis water than tap water. Lucky i live in a country that prides itself on water, that being said it lacks cal/mag.

Was just hoping some would try a bottle or two on 'ONE' plant to see if it made a difference good or bad, technically those in soft water areas should see a very big improvement as the plant got the much needed calcium and magnesium from the water.

I been through 18 litres since the start of the thread and cost me a lot less than a gram of weed so i dont see how it is too exspensie or unatainable, damn in my household 70 percent of the water we drink is mineral water so sparing some for my plants was nothing to me, i suppose buying mineral water is a big deal to some!

Anyway i wasn't recomending it but just wanted to see its effects on cal/mag deficient plants, i would buy some exspensive cal/mag supplements but i think better than wasting my money i will find a cal/mag rich fertilizer.

Good things come to those who wait and i certainly do my homework whilst i'm waiting. I could just go out and buy some grow products and ferts or i could look into the issues and make sure i am making the right and informed choice.

Thankyou for a straightforward answer but please understand it would have been only for a week or two and just one plant out of a whole grow, take a few litres max to do this little experiment. Oh well i didn't expect a big turn out, people just want one line simple answers when it comes to plant problems whereas i want the whole lecture and signed autograph.

Rep for not calling me a retard at least. Peace

yeh it was ok, i got fed up with buying it in the end, but i agree with what you are saying, as a test, its well worth it, less hassle and no waiting time for stuff to arrive.

Thankyou for the kind comments, thats all it was a test. I in no way recomend growing in mineral water and recomend cal/mag supplements for cal/mag deficiencies but knowing that Evian clears cal/mag deficiencies is a very usefull thing to know.

In an emergency a bottle of Evian could be priceless when waiting days for some hydro company to deliver some much needed cal/mag supplement and even used for quick diagnosis. Fancy spending some loose change just to find out wether you need an exspensive cal/mag supplement or not.

Hopefully you see what i'm getting at but i dont expect everyone to share my enthusiasm for growing. I really seem to notice the effects of cal/mag deficiency and have learnt a lot about it and water by looking into it.

Just out of intrest iNfiD3L you say it worked well for you, please tell me if it was cal/mag related for your grow and if you went on to buy a seperate cal/mag supplement after discontinuing the mineral water, i would really appreciate what you would have to offer in terms of experience here. Thanks and Peace

Cal mag is like $17 for 1 quart (967 mL). It takes 5 ml cal mag per gallon of water. So one $17 bottle of cal mag makes about 193 gallons of water, which is about 8.8 cents per gallon of water with cal and mag in it.
