An excellent thread here on cold treatment, well worth the time to read it all. I had cold treated some of my seedling last year and felt those plants on average took off better and set more early fruit.

I don't start seedlings for outdoors till April, but have been testing seed and media this month and thought I'd share a some before and after pics of 2wks of cold treatment. This might help some in estimating how much earlier they may need to start if cold treating.

These are Crnkovic Yugoslavian seedling packs separated at the first emergence of true leaves Jan7 and today Jan21, all T5 lighting.
