Problem slightly different

jwr6404 · March 25, 2009

I have 60 seedlings of 20 different varieties. One of the varieties is Stump of the World(4ea). All the SOWs leaves are turinin Yellow along with 1 Big Zac. The other 55 plants are doing fine. They are in an upstairs room under lights 24 hrs per day. The lights are 1-2 inches above the pot The temperature runs between 65 degrees(night) and 74 degrees day. All are in the same type,16 oz container. Question? Do I have any need to worry? I do want at least 1 Stump.

24 hour a day light is too much - when mine are under lights, they go from 8 AM until about 8 PM. Also, get the yellowing ones some gradual sunlight on nice days. Tomato seedlings don't enjoy being under lights for too long - the fresh air and sun really helps them to be healthy.

will turn the lights off at night beginning right now. Still to cold to put outside now plus here in the PNW this Time of year NO SUNSHINE

Yes, we lived in Seattle for a year, so indeed do remember - sunshine is scarce at this time of year (though I think we were lucky - it was not as nearly a rainy year as we feared it might be)

I left a tray of seedlings out from around 11:00 am to 7:00 pm
today (cloudy day, no wind, no sunburn risk, ran out of space in
the coldframes). They looked fine when I brought them back in.

They probably do not grow much at 50F on a cloudy day, but
they do not particularly suffer either, and they do get a little
hardening off done.

Just check the weather first (don't want to drown them or fry
them), and keep an eye out for sudden changes. Worth a try
with plants that are struggling anyway.
