I've been carefully acclimating seedlings grown under grow lights to the outdoors with intention of planting them after May 1. After 5 days seedlings are now exposed to 4-5 hrs. direct sun but mornings until 10 are often below 50s &I bring them in when it gets dark & below 50. Should I put them back under grow lights when I take them in because it seems like they'Re getting less light in this hardening process. Also, I will have to leave them for 3 days & I don't think they'll be ready for transplanting by then.
