Ideal 420 soil looks like a great mix, but the price tag.... Wow.

Here are the basics as I see them. You want to start with a very neutral medium. Reg is using straight peat. I use Sunshine #4 (yellow lablel) others use Pro-Mix HP. The next step is to improve the drainage. You can use perlite, or lava sand.

Note that KJC uses a very similar mix. He also adds vermiculite to his. Vermiculite holds water like a sponge. It does not improve drainage. Add some if you want, I suppose.

Next, I add organic material and mineral components to the neutral mix. When I do that it becomes a soil as opposed to a soilless mix. It has high CEC (cation exchange capacity) and is well buffered against pH fluctuations.

Those are the basics of building a good soil for your cannabis.

What is nice about the Yum Yum (alphalfa meal, cotton seed meal, kelp meal, green sand, rock dust, rock phosphate, humate, and dried molasses) is it is already mixed in a nice ratio and removes much of the guesswork about how much of what to put in the soil. It also means you don't have to store a bazillion containers of amendments.

The mix Reg is using is a dumbed-down version of the mix I use, but I think it will work very well.
