Well part of the point of WS is to "set it and forget it". You would get the cold stratification you need using the GH, but YOU would have to water. WS in the open lets Mother Nature do the watering for you until they sprout and things get warmer outside and the containers can dry out quicker.

That's my 2 cents any how. Good Luck!

I'm not worried about the watering part. I guess I'm just restless to get on to starting the seeds again. Even if it is only to look at pots of dirt for months while waiting for spring to come!
I've still got hot peppers ripening out there and already I'm planning for next year.. :)
