Cabbage thinning.

[thesnapman44]

I have planted some cabbage seeds ( Ferry`s Round Dutch ). They were not in their original packet, only in a container with the name of them on the side. They have grown to just less than half an inch, and doing good. There are about 2 or 3 to each pot. At what size do I start thinning them out ?
Thank you.

They require a good bit of space, normally planted about 18" apart. It's a cool weather crop. What size pot are you using and how much light are the getting. Are you growing inside or outside?

You could thin them now.
