Here's a test question for all the math genuis out there.

Espoma® Pelletized Dolomite Garden Lime



Calls for 4 pounds per 100 square feet for the PH level I want.

Growing in 3 gallon pots.

How many Tbsp. per gallon?

Don't need a flame thread on Espoma, just some help with complicated math.

1 US gallon = 256 US tablespoons

We need a calculation for the pounds per 100 square feet to 1 US gallon.

I know standard measurement, Here in the US we're stupid when it comes to the metric system..

ok so if it takes 4 pounds to 100 sq feet. then divide that by 4 to start of so that it is simpler. 1 pound to 25 cubic feet. k then you have to figure out how many gallons are in 25 cubic feet. in 25 cubic feet their are 160.71 gallons. ok so then you take the 160.71 gallons and divide it by 3 cause you have 3 gallon pots, it takes 53.57 (3) gallon pots to make 160.71 gallons ok then you gotta start converting the neautralizer into smaller easier to work with amounts. and it takes 16 oz's to make a pound so for the last part we will take a liquid ounce and convert into table spoons ok so it takes 32 tablespoons to make 16 liquid ozs ok and then we take 53.57 and divide it by 16 and get 3.34 ok and to convert that into tablspoons divide it by 2 and that equals 1.67 so that is 1.67 tablespoons per 1 gallon of filler. cause if you take 1.67 and multiply it by 32 that equals 53.57 so it is perfect hope this helps you and if it is confuesing to understand just go by the bold part for directions.

and just to let you know i thought that seemed like alot so i did the math to look at howmany tablespoons are in a gallon and it is 297.89 tablespoons to make 1 dry gallon

I guess it depends on what your putting it in. Like what's already in the soil eh?
but I usually put 2 tbls per gallon. But I also use powdered dol lime.

just to let you know if you go to a converter site this mesurement if for 1 us liquid gallon to 256 tablespoons mine is for 1 us dry gallon.

Going in 90 % peat moss and 10 % perlite.

I do believe that dolomite lime cannot raise the PH past 7, so it isn't dangerous to apply a little more... But I am pretty sure it's 1 tbs per square foot....

A standard milk crate is a square foot of soil.

I think that acidity actually causes dol lime to react thus buffering the ph but releasing calcium and magnesium at the same time and maybe getting to "toxic" levels.
just my thoughts, not stating it as facts.

sorry my post was a little bit confuesing but it is 1.67 tablespoons per gallon from my math but from what people have been saying i would say anywhere from 1-2 is a safe number per gallon.

Right on my man, I'll start it at 1 Tbsp per gallon.

yeah no problem man hope that i helped you out but yeah i was glad to see that my math ended up closly to what other people have already used.

Pelletized dol lime works slower than powdered though.

This isn't a emergency due to plant health or PH levels. This is a new grow, Mixing throughout my soil mix of Peat moss and Perlite. Nice product, small round balls like airsoft ammo but not hard, more like soft mud. Able to smash with finger.
