How much lime do I mix into the soil?

[TheRuiner]

This is what I'm using, my pots are 2.5 gallon, or ten liters. How much should I mix in with my medium?

bump... about an 1/8th of a cup perhaps?

Cold.... i guess this is a dose of my own medicine and I deserved it, I'll start searching and googling...

I know what lime is used for, but why are you wanting to put it in your mix? Its not needed for cannabis, especially when grown in containers. It will create alkali conditions in your soil that you'll only be able to offset by giving it acidic water. If you use a good mix of perlite in your soil, you'll have good drainage and you'll be able to maintain proper ph just by giving it balanced water and plenty of it, so as to prevent sodium build-up and ph lock. I suspect this is the problem you may be having and are trying lime to offset it...I may be wrong.

3 tablespoons.

Thanks, I came to the conclusion of 2 tbls by reverse engineering the 4-5 lbs per 100 square feet.... and then shaving a little off the top. Props and +rep, good man!

Fortunately I'm not trying to correct any issues with this grow yet, the lime is just a supplement for my soil which consists of FF Oceans Forest and Happy Frog (equal parts) earthworm castings and now a small amount of lime.

I usually water with a 4.7 ph well water I get from an aquifer that my house sits upon, it smells of sulfur and comes out nice and cool year round. I normally cut it with a little RO water with a PH closer to 7.8 so things are closer to the 5.5-6.2 mark when watering. I don't think using the lime will hurt anything, it should only help as long as I don't ass too much.... the girls are sitting in some strait up happy frog right now and seem to be very happy, I'm just ready to kick things up a notch and I decided to include this in my medium a while back. 2 Table Spoons it is for a 2.5 gallon bucket!
