Winter carrots, mainly

Hi all,

I'm reading Eliot Coleman's The Winter Garden, as I'm wanting to extend my seasonal offerings for my micro market farm. I'm in western Washington State, zone 8b. I'm just wondering if any other market gardeners here have grown winter carrots in a similar climate in a cold house and if you have any tips you'd be willing to share to give me a better chance of being successful in my first winter growing season.

I've cleaned out half of my high tunnel from summer veggies, so I'm starting my carrots just now. In the next week the tomatoes will be out as well, so I'll be adding some lettuces, hakurei turnips and kohlrabi.

Again, if anyone has any winter cold house growing tips for the uninitiated, I'd welcome the wisdom.

It seems phesible.  I mean when I tried overwintering radishes and lettuce they went into "stasis" as long as I brought their pots in when it got freezing at night.  But I think in a cold house/high tunnel/anything that makes it slightly warmer they'd have kept growing.  I'd imagine carrots are similar.
