PH question. - Indoor Grows - Soil - International Cannagraphic Magazine Forums

I've read that you can raise ph by adding lime. But in most cases it says to add the lime to your soil mix. My question is, can I add the lime to the top of the soil and just water it in with its regular food? I'm about 25 days into flower, so I can't repot. Any help or useful thoughts are appreciated.

usally people dont do that cuz it locks up the nitrogen if i rember corectly..you can use dyno-grow which has calcium in it+if you did do the applications of both they would hav to be 2 weeks apart...if me is rembering correctly,appling the way you suggest.im not sure if you could tak a 1/8 of a teaspoon of lime to gallon of water and use lik that,i dont know if that would inable you to applie the fert. sooner,this way? i not sure if organics would work lik this,but that how chemical ferts. react with lime. peace the fred...

u can transplant 25 days into flower dont worry u can also use ph up in your water(avail in the pet or pool store) to raise your ph i usually measure the runoff frob pure 7.0 water to find out how much i need to adjust.

Duffman, I heard you can use hydrated lime (which is fast acting) mixed w/ water and it will raise the pH. I'm not sure how much to use but I believe it is very easy to burn using it. Next time use 2 tbs of dolomitic lime for every gallon of soil mix.

As far as watering it in, I don't see why it wouldn't help atleast. Don't ecspect it to work immediately though. The dolomitic lime you topdress w/ needs a couple weeks to break down before it will become active.

Well I found some hydrated lime at franks nursery. It said on the box to add 1 tablespoon per gallon of water. But it also said its pretty much a one time application when adding it to water. This is all new to me so if anyone has done this, how often do I need to add lime water to my plants? Just once or will I need to check the ph in a week or so to see if its helping and maybe add some more? This I do not know, any help is appreciated.

Also will hydrated lime work in the soil the same as dolomite lime?

I'm really not too sure about using the hydrated lime. My suggestion would be to start out slow... say use 1/4 tbs. or 1/2 tbs. at first. You really need to transplant them into some soil w/ the dolomite lime. You'll be alot happier you did. You can pretty much say adios to pH problems. I used to be in the same boat as you until I started using dolomite lime. It still helps to pH your water/nutrient you give 'em though.

Oh and to answer your question about hydrated vs. dolomite... the hydrated is fast release so even if you mix it into your soil and it doesn't burn the plants, it won't stick around too long in your soil because of how fast it is used. So obviously the dolomite lime is slow release. That's why you have to premix your soil with the dolomite lime 2 weeks before you plant in it so it can start to help with pH. Also, make sure you keep it moist and stir it up daily. Oh and just to say I said it... the dolomite lime will not be available for the plants (Mg or pH) until it is moist for a couple weeks. This is because it needs to be broken down by micro organisms. Also, if you use chemical ferts it might hender the lime a bit. It's kind of a no-no to mix chemical (salt) ferts w/ organic ferts.

Sorry if I rambled too much!

I agree -I did a transplant on mine at 30days flowering and they did not mind at all-just be gentle(I had them in a far too small pot and it was transplant or let them die.)I also hit them with 1 ml /gallon of water superthrive and 1/4 tsp soluable seaweed extract at transplant .no shock or wilt at all and they are growing like weeds.(or weed at least)

Guys, thank you very much! From now on i'm going to be a lime man. Your answers were just the info I was looking for, very detailed. Thanks. I can't find dolomite lime for some reason, I have been all over the place and no one has it. I think it is a little early in the season for the garden centers to have it around here. I will find it eventually. Thanks again for the help I will post my results when I have some.

Keep it real

try sunnyland lawn and garden lime in the yellow and white bag.

Duffman · 03-25-2004, 10:41 PM

Well I have some results. I tested my ph today and it has went up to 6.5 which is about 2.0 higher than it was. I will test the ph each time now to see how long it holds steady. My ladys have all perked up considerably so this has been a great help.

Another question to you guys, when can I start giving my plant fert again? I just gave it water today but I wasn't sure when to start giving it food again. Thanks for all of the help, I'm still on the lookout for the dolomite lime.

PS: has anyone ever seen the movie Dolomite? It's funny as hell!
