I would imagine it's very much the same, except you cut holes in the dome or perhaps install a flap.

Hi Adair:
It seems you are new to this forum so welcome. For full details on Winter Sowing (and Spring sowing) you can go to www.wintersown.org. It has a section on types of containers you can use, and you will see the set-up for using foil pans and domed lids there. They sound like a perfect choice. Good luck!!

I am new to this forum and I find it extremely helpful to say the least.I never knew it could be so much fun growing seeds,but also it is hard too. Living and learning...

Thanks for Everything
