Is water temp. and water pH related in any way?

hey second grow here, first grow turned out magnificiant

with the first grow i had minor issues with low pH, this time im having an extreme problem with high pH and its only week 1:!:

i was wondering if maybe the slightly cooler water temp might have something to do with it?

any ideas or help would be greatly appreciated?.

Wow, that's brilliant. Why don't we just do away with this forum altogether and just ask google everything? :rolleyes:

good idea


yes pH does change with temp but its really very minor. Look at a calibration solution you'll see its made to read a certain pH at a certain temp.
 
This is a pot forum, so it makes it easier to find specified pot information. Ph is the same if you're raising fish or growing roses, and for general information google is superior to net forums. This is exemplified here where more than 1 poster has given incorrect information.

How about taking a less offensive approach to giving answers to someone's thread then? Since you're so in touch with google, why don't you just answer the damn question? I'm sure that's what the OP was asking for in the first place.
 
My point is that pH does not have to be exact for what we are doing, which is not the case for other things meters are used for. If a pH swing is severe enough to care about in growing weed, I don't think it can be caused by temp alone. The OP didn't say just how severe the swing was, but he did say the res temps were lower and the pH was rising. So the temp as a cause is pretty much eliminated.
 
yeah, yall got off corse earlyer. my original question was if the cooler res temps could be affecting my pH?.. not if the pH was affecting my water temp.. silly billy

I gave them the way to the answer. If you're too lazy to look that's not my problem.

Wow for a person who seems to knows so little about the topic you sure being awfully toxic in your replies.

The answer is not so easy as you would have it be as the question is likely not being interpreted as your limited knowledge is causing you to interpret it. At low temps ammonium nitrogen is typically taken up in larger amounts than nitrate. This means the roots discharge H+ protons into the reservoir so as to maintain and ionic balance in the plants roots. This means low temps will cause a declining pH that can be very dramatic. At high temps nitrate is taken up in larger proportions leading to the roots discharging carbonate ions that cause a rise in pH that can be dramatic.

Now consider he made no reference to any other changes such as nutrient concentrates or changing nutrient formulations. Then co sider the fact that temperature effects uptake efficiencies as well. then consider you nor anyone else whether he is using organic or inorganic fertilizer. Organic fertilizers run a different pH at different temps as the reservoir bacterial levels change in relation to temperatures. This effects the pH.

So in that respect your quite likely just talking trash and making bad suggestions by thinking goggle scholar is providing a better answer to pH problems specific to hydroponic growing pH problems than can be supplied by knowledgeable mj growers rather than inexperienced growers using goggle and likely asking an irrelevant questions. If you ask the wrong question you will get the wrong answer. You pretty likely asked the wrong question Dude.

Sorry Knickers but your advice and opinions might very well be worthless to mj growers. It is the result of growing at lower reservoir temps that are likely effecting the reservoir pH problems, not that pH "readings" are effected to a small degree by solution temps.

It is as simple as, don't bother asking goggle a question unless you are knowledgable enough to ask the right question Dude.

There was a period of over 36 hours witout an answer to the thread starters question after his clarifying the original questionm, which seemed simple even in its original form. I posted and answer without having read the second page of replies and his clarified question. What is up guys. It is knowledge I have posted repeatedly so it should be well known information already. It is information widely distributed in scientific lierature I have previously posted links to. I had to almost beat it into Uncle Bens thick head in the old Scientific Nutrient thead. It is easy to understand. It is the basic ground work for buffering in hydroponic nutrients.
