Seed starting mixes are often very simple. But there is one thing that sets them apart. It’s a hidden ingredient that makes all the difference. It is missing from most seed starting mixes. That secret is dolomitic lime. A crushed limestone that pH buffers soil and makes your seedlings far happier.

Haha I was in the store Friday and asked why I can't find it in stores? Lol
Thank you for posting this. Today I was going to start seeds today. 😊
It's that time of the year! Always learning something from your videos!
Where did you get the PVP perlite for $25? Everywhere I look its over $40
It is super exspensive where I live in NY
Thank you very useful information.
I've been growing seedlings for several years and never used lime and my seedlings do good. My soil is very alkaline so I wouldn't want lime in my soil at all.
