Background: I sowed my first batch of tomatoes on April 4th on those transparent 12-grid trays w/ domes that are supes trendy right now, potted them up on May 4th & 5th into 3-inch transparent pots (which I now understand may not provide the ideal darkness for their roots, live and learn), and I would like to transplant them outdoors soon.
Questions: One concern that I have (and I'm not sure how concerned I should be) is potentially introducing outdoor wildlife into my indoor environment during the hardening off phase.
- Do other gardeners worry about this or am I over thinking it? Is it basically set them on a table (not on the ground), don't leave them out there for too long, and hope for the best?
- What other steps can I take to keep my indoor environment as sterile as possible while hardening off some plants when they're ready?

I see, so you just open up the cold frame for a few hours a day until they're ready for full time?
Keep it open for airflow and to keep temps down during the day, and close it at night to keep the heat in and protect from the frost. Also keeps rain and snow off as well.
The top opens as well.
