My seedlings are happilly growing under fluorescent
lights. At some future point I will need to begin
hardening them off.
My basic questions are:
1. When do I begin this process? Our days are approching
highs of in the upper 50's and nights in the mid 30's.
2. Is a cold frame necessary?
Where do I find a link on construction of one?
3. Can I just place the younng plants in a warm partly
sunny place and bring them indoors at night?
Thanks for any help.
