not growing

Greensburg, IN(Zone 6a)

I started Angel Trumpet from seed, they came up great, they have very fat trunk, they are all about three inches high but then stopped growing, they are in a mini greenhouse with grow light, what should I do.

How many hours of light are they getting?

Brugie, they are getting light 20hrs automaticaly turn off light from midnight untill 4am

Wow, that is a lot of light. Maybe you should cut it back a little. They need some dark time to rest. I don't know why they wouldn't be growing, but it is probably good. You don't want them to get leggy and too big before you can put them out next spring. I don't have my seed started yet. I was going to this week, but other things got in the way. We have had four days of no sunshine now, maybe more. I'm needing to see it as much as my plants.

OK Brugie I will try cutting back on light by putting them in place by themselves.

Don't get me wrong...I do keep my seedlings under light, but only about 12-14 hours of light. When they get big enough to be potted into individual pots, I put some of them in my bay window that faces east and those seem to get bigger with natural light than the ones that have to be under artificial light all day.

good, I have window facing east, will put a couple there and see if it makes a difference.

Brugie,
I've been leaving my lights on for my EE's and Brugs.... should I be turning them off at night for a 'sleep' period....?

I just copied this from a web site: Plants NEED Darkness
Plants need dark periods. Light (called photo-periods) and dark periods and their relative lengths have an effect on plant maturity. Recent studies have conclusively proven that it is not just the length of the day which affects growth, but the duration of the dark period which follows. The dark period of each day affects flowering and seeding of most plants. Although many plants can grow under continuous light, nearly all plants prefer a dark period each day for normal growth. All plants need some darkness to grow well or to trigger flowering. The ideal photoperiods of plants vary, some preferring long days and short nights; other the reverse; and some do best when the length of the night and day periods are equal. http://homeharvest.com/whichgrowlightisrightforme.htm

Have you foliar fed yours yet Kareoke? I give mine weak sprays of fertilizer. But Brugie is right, unless you have lots of indoor room, you do not want them to grow too fast. Mine have to stay in till late February/March.

yes kell but very week, I don't mind they are slow, just wanted to make sure they were OK they look very healthy

Guess I'd better cut the light time down some.
