hydro guy with a stupid question about soil

*I* use 2tbl/gallon of mix, or 1cup/cf of mix.

It all depends. My peat based mix is very acidic.

Here's the thing, lime (the kind we want anyway), is nothing but ground up rock (limestone).

I have grown plants (not mj), in nothing but coarse crushed limestone. Wasn't intentional or an experiment, just all I had at the moment. Had a dump truck load of it in the side yard.

The drainage sucked, but it sure answered any question about using too much. LOL Normally I would use a shovel full or 2 per wheelbarrow full of mix, ~2cf.

thanx for the reply!
take a gander at my latest questions i just posted if u have time bud

so having lime ever-present in the soil is a good thing?,, like it wont raise the PH too high the more you put, but instead just be available when needed? within your recommended amounts

Refined ashes will act like ph up and domolite lime will act like ph down. The ashes are powdered and screened. In eg if you have a ph of 5 you can raise it with ashes to the desired ph level.

I'm sorry, but you've been misinformed. Lime raises PH.

Here's a good bit of info to check out:

Hey OP, sorry to jack your thread.

In my op I use a color coded ph liquid test kit. The water I use comes from a very deep well and it comes in off the scale at over 8ph. I use domolite lime to bring the ph down toanywhere between 5.5-6.3.

im trying to get some simple questions answered by people that are familiar and experienced with soil. it's apparent from things you've said that you are not one of these people. this thread isnt for you to defend your case or debate about what YOU do.

but thanx 4 stoppin by and good day

Adding lime to water? to LOWER pH? So much for credibility....

[edited] Now if you are talking about citrus lime, that's one thing, but you did write dolomite lime, thats why I'm doubting ya.... Dolomite lime is a sweetner, it raises pH. A citrus lime or lemon would lower pH due to it's acidity.

i don't ph my water , the soil will buffer it to it's ph , all i do is dolomite lime . i also have never let my tap water sit out , straight from the tap to the soil after adding dynagro.

Dolomite Lime is the key to growing in soil.

I found it's better to address the soil than the water. You can take and test soil samples with litmus paper or a pH kit. If the soil is acidic, add powdered lime, about 1 tsp per gal of soil, top dressed and watered in. If the soil is too base, use bone meal or an azalea fertilizer with ammonium Sulfate. Avoid sulfur-coated urea as it can burn the plants.

thanks alot. i'm a dwc'er thats trying sunshine mix #4 for the first time and have been getting frustrated because i can't seem to get the ph below 7 by using hydro ph down. don't know why i didn't think of the alum sulfate. i use it to lower soil ph for my hydrangeas
