Serse, I see you have already met more of the semp lovers, and they've all given your great advice.
I agree with Greg and Chris, semps love the cold. You might want to pot your new plants up and set them outdoors. They come from a nursery that grows them cold.
Also, just so we don't keep asking your where you live, you can go to your profile and add that information, along with your growing zone. It will show in all your posts in the upper right side. Just like Chris, Greg and Spring's.
Trading will start up probably about March, when weather starts moderating. For the northern members that may still be covered in snow, it might be April or May.
Many of us trade our semps for other types of plants.
Greg's suggestion about using the List feature, at the top of the page, is a great way to keep track of what you would like to trade for, and what you might have to trade. It is a great tool.
If you need help with anything, just ask any member here at ATP. It is such a friendly group of people. We love interacting with other plant lovers.
