There's a big difference between fluorescent lights and the brightness of real sunshine. Their first day out, seedlings should get no more than an hour or two of sun. Ideally, they'd get another hour or two of sun each day until they're enjoying the same amount of sun they'll get in your garden. If that's not practical, putting them in a partly shaded location for several days before moving them to a sunnier location will work fine.
What does it mean to harden off seedlings?
Hardening off simply means getting your seedlings used to outside conditions gradually.
How to get peppers to grow outside?
Find a sheltered spot for hardening off. Gradually move seedlings to a less sheltered location. Scout around and figure out where your seedlings will spend their first hours outside. A location that's out of the wind and partly shaded, especially from harsh afternoon sun, is ideal. I've learned the hard way not to set them directly on the patio. One year, some varmint bit the stems off several dozen pepper seedlings! Now seedlings get set out on a table, so they're a little less accessible.
How to grow a sage plant?
Day One: Put seedlings outside in a sheltered, mostly shaded location and bring them in at night. Day Two: Give seedlings a half day of sun, and cover them at night. Day Three: Put seedlings in sun for most of the day, and let them stay outside for the night, uncovered but out of the wind.
How to keep a squid in the house?
Decrease protection from cold at night. Always bring them inside if temperatures drop near freezing. The first night, bring them inside. The second night, bring them inside again unless the low temperature forecast is especially mild. By their third night, they'll have started to toughen up a little and can stay outside in a sheltered location, perhaps up against the wall of the house. After a couple more nights, they'll be OK in a less protected location such as a few feet away from the house. The idea is to get them used to cooler night temperatures in stages.
When to unzip seedlings?
You'll probably have to unzip them during the day so your plants don't cook. As your seedlings progress, leave the door unzipped at night also.
