For soil grows Ph doesn't really matter. Generally speaking tap water is and well water are fine for growing a plant in soil.

Picture a half acre outdoor grow in NorCal. Do you think they are Ph'ing 1000gal a week. Nah...

Just water it. You'll be fine.

thanks man my ph is 5.5

that is pretty low for soil though. Just read it's well water right?

For tap it's always like high 6's to high 7's. But well water isn't treated (obviously).

You might want to bring that up to mid/high 6's dude. 5.5 is the bottom end for hydro.


Edit- I am curious to see how soil grows will do with that low of ph though. Can you do two grows. One with the 5.5 water and another Ph'd to see the difference?

Tap water is never reccomended, it can contain more ppm then you want your plant to have, and will cause you all sorts of problems...try to find out from your local city hall the ph/ppm of your city water. 200ppm is around what you want it to be. I boil all my water sonce i have a higher ppm then desired in my area.

Your PH is ideally 6.3-6.5 in soil, but the plants usually tolerate between 6-7.

There are some strains out there that love to have 5.5 as there PH...one strain that i grew was white widow (the original) and she loved it...Greenhouse seeds reccomended it as well.

Even in soil, if your Ph is too low (or too high for that matter) you will have the same nute lockout issues that you run into with other methods (I'm talking about growing indoors in pots, not outdoors in the ground). That being said though, soil growing is MUCH more forgiving of Ph issues than other methods. I know on my indoor soil grow i adjust my water/nutes solution to a Ph of 6.8 to 7.0 generally. This gives me a runoff Ph of somewhere between 6.2 and 6.5 which seems to work just fine for my girls. It may be overkill, but before I started adjusting the Ph of the solution I was having MAJOR problems with nute deficiencies. Once I started adjusting it up (it always seems to come out at 5.9 or 6.0 before adjusting) the problems all went away, so I'll keep on doing what works.

no its not well water its tap water. thanks guys ill add a lil ph up

"The dirty South", lol.

You must be somewhere in my neck of the woods!!!!!

prolly so where you at?

I heard 6.8 is good for soil water...
