Ph Level Help!

[t's-buds]

what is a good ph level for my plant? my moister/light/ph 3in1 meter said that most indoor plants like the ph to be slightly more acidic than alkaline. is this true w/pot plants too? it also sais that if the soil is to high in alkaline the plant will lose their color and stunt the growth of the plant, but if to much acid in the soil willcause the leaves to wilt and drop. is this also true w/ pot?



next,
what plant does pot most resemblevin growing if any

Indoor for hydroponics is 5.8-6.8

Yes

if to much acid in the soil willcause the leaves to wilt and drop. is this also true w/ pot?

Yes an acidic soil can lock up nutrients and they won't make it to the plant.

Peace.

in case your short on cash.. use vineger & baking soda to adjust the ph level..

They say the closest plant to mj is a tomato plant.

I try to keep my soil at 6.2-6.5.

 

[Garden Knowm]

yeah what they said...
: )

soil is so forgivng that as long as you can get the PH of your water between 6-7.. you will do FINE!!

for hydro it says ph should be 5.5-5.8, but at the top it say 6.8 . Witch is best?

Vinegar to lower, baking soda to raise

dude control kits are dirt cheap and can e order online maybe 16 bucks at the most and usually they come with a strips to test it out

 

[smithy]

is this the same with clay balls?

 

[Twistyman]

hydro 5.5 - 5.8...soil ..6.2 - 6.8....

Ive been using nitric acid to bring the ph down . . . any one know if this is good or bad.

It works for me in lowering the ph although it is a nasty chemical to work with.

actually ph for hydro should be between 5.4and 6.8 no lower no higher but if its between that it dont need to be adjusted

I got a ph level tester today from walmart for $5

 

[lvpete]

5.8 is perfect

 

[CaliKushSmoker]

5.8 is the best for some dank buds

I like to keep my water for spraying a nuetrul 7, u can pick up cheap fish tank products that can determine ur ph and adjust ur ph up and down, for a lil under 20$

If you are serious about your growing DO NOT use baking soda. Baking soda is Sodium bicarbonate. Salt. Go to the grow store, and spend seven dollars to get a hydroponic Ph adjuster. If you still want to cheap out, only use Apple cider vinegar to bring down the Ph.

I think you would do better with cider vinegar . Its also a natural estringent for a good flush. (just a few caps in with fresh water flush) Its got to be better than strait Nitric acid.

Now I've heard that vinegar (organic kitchen acids) works just as good as inorganic acids (HNO3, H2SO4, HCL).

Sombich told me that the vinegar looses its acidity due to breaking down in the soil? I think this is a little bit fetched because the protons will still stay in the soil causing the acidity.

Sombich told me that if you use nitric HNO3, the nitrate ions will contribute as a nitrogen nutrient. But I think adding a few ppm of nitric to get my ph down is not going to do much as a grow nutrient.

Sombich told me that H2SO4 will add sulfate to the soil. I know it's a damn good acid for downing you pH because it's a dual proton acid and kicks in really good. Also, I seem to remember that sulfate is a good trace mineral for the plants.

Sombich told me that HCL (hydrochloric, muriatic) adds chloride ions to the soil and causes it to get salty. I think its no big deal because its only a few ppm to change the pH and that will never cause a significant saltiness to the soil.

I'm using H2SO4. It's a very effective pH down and it's useful to put a little bit of sulfate in the soil. The only proplem is I get my H2SO4 from my lab at my university in a very concentrated form. (one drop in a gallon of water will change your pH by 0.5). You've got to use a pH meter with concentrated acids.

Following the same theory I use NaOH, sodium hydroxide to change the pH towards alkaline if I need it. I actually us the NaOH quite frequently because my nutes make my feed water about 4.5 pH. So I'm constantly raising it.

Ok, so watching the video and reading up, I understand how to measure ph, adjust ph and so on. But, my question is - what about the MEDIA?

Does it not have an impact?

Media such as Pro Mix, or Miracle Grow, or even hydroton / perlite - do they not have a ph?

So wouldn't the water have to be adjusted according to not only the starting ph of the water, but also what the ph is of the media?

If my water is ph 8, I need to drop it by 1.5 points approximately, but what if my media is ph 6? I would think I do not want to drop is as much since the media actually needs to come up. ??
