Lime in Homemade Potting Soil

I wanted to try making potting soil but am new at this....does it matter what kind of lime is used? I have Sta-Green Rapid-Lime with Soluble Calcium but have seen others recommend Espoma Garden Lime...is there a difference between the two? I just don't want to ruin anything by using the wrong product.
I'd appreciate any suggestions.

Hi E, The powder form is more available and quicker than the granular. If you have granular...you can put it in the blender and break it down. Dolomite (garden lime) with a calcium/magnesium ratio of 2-1 is perfect. This balances the acidic properties found in peat-based potting mixes.

I also recommend dolomitic lime. Do you know how much to use in your mix? Too much is worse than too little.

Oh my goodness, I read the title and thought someone was mixing lime (Citrus ×latifolia) with potting soil...my bad. Sharing because of the absurdity of it all...

Thanks for your replies. I'm confused whether I can use this lime in a homemade potting soil? I got it from near the grass seed section of the store- the bag says Sta-Green Rapid-Lime with Soluble Calcium.
I read about Al's 5:1:1 mix on the forum and wanted to try making it..I should've mentioned that before...

To add my 1 cent to this convo in a meaningful way. If it's pure lime (read the contents...hopefully they labelled) and not a bunch of other stuff, I'd feel free to mix it in cautiously.

Cautiously because more plants prefer neutral to acidic soil than higher alkalinities.....

Do you have a goal as far as your PH is concerned? Depending on what you are planting, or just to reach a neutral state? It is easy to check the PH. A test kit for PH is easy to find. Al

dbarron, It looks like it has Calcium 38%, magnesium 0.4%, humic acid 2%, lignin sulfonate 8%, but there are other things on the label I don't even know how to read (minimum ECCE 94.19%, calcium carbonate 95%, etc.).

calistoga, I wanted this soil for some basic house plants because I'm not having luck with the pre-packaged soils (I think they are too heavy and stay too wet); I was just going to follow the recipe exactly and see how they did...
