How 2 Lower PH in Soil..

[bullSnot]

Muriatic acid? We are growing plants here not washing cement....the smart way is to add 10 tbs of epsoma garden lime (dolimite) in your 5 gallon pot and mix it up well, water and mix again...it buffers the ph and adds cal mag...but I did not do this on this grow...paying the price

I have a indoor grow I'm using 5 gallon buckets and I'm just wondering how do I check the PH of my soil and how do I change the PH of my soil if I've already got plants 9 weeks into Veg. in the containers?

Thank you in advance!

If you have enough healthy soil, you don't need to use pH down. If you measure the runoff water you will find that more often than not, the runoff will be in the safe zone and that the soil and bacteria buffers itself.

You can buy little soil test kits, you put a bit of soil in, some water, shake and let it stand then read off the colour chart.

Dolomite lime is a ph buffer.. add 1/2 cup to soil mix.. don't have to worry about ph..

Thank you for the info. If my soil does need the Ph balanced is there a way to mix in Dolomite Lime or something else to adjust the Ph of the soil in my 5 gallon buckets? Or no because the roots are already developed?

The only solution I can think of if my soil isn't in the safe zone is to transplant them into Ph'd soil.

You can always up the pot size a bit, and use whatever amendments in the space between the root ball and the pot.

You can top dress with the lime and it will get watered in... mix it well or add additional soil..

Alright so should I mix the Dolomite lime with some water and just pour it over the soil? Or would it be better to put the lime powder directly onto the soil and then just pour water over that and hope it runs all the way through the soil in the container?

Thanks for the help HydoDan!

Gotcha, thanks ANC!

be sure you need the extra mag and cal though
may want to consider calcitic lime instead.
furthermore may want to consider a grow organic mix predicated on compost or other fresh humus based mixes.
a properly made organic mix will regulate the ph on its own, via the root exudates. Yet another reason why re-using an organic mix is preferred.

What do you mean? If say you use FF nutrients it will be in the 5.0-5.5 range ....by the time you hit half way through flowering your soil PH will be there also...showing signs of Cal Mag deficiency as it cannot be used at that PH level....they should always PH the water and nutes...up or down

Best to work it in and water.. It's not very soluble...

 

[bullSnot]

I have always just scratched it in. You want to slowly change PH not in 24-48 hours. Use dolimite lime it adds calcium and mag ...be patient grasshopper it should take 7-10 days

Ok thank you HydoDan & bullSnot !

USE LEMON JUICE NOT VINEGAR.. WORKS GREAT..

ABSOLUTELY, been using lemon juice for many years.

Just get some citric acid if you're adjusting water pH. But if you want to lower soil pH, sulfur.
