What are the Consequences of Leaving Lights on 24/7
My seedlings are just shy of 3 weeks old. Almost all have their first true leaves and several have their second true leaves. I have a 2 bulb t12 set up and I leave the lights on all the time. I turn a fan on them a few hours a day and they seem to be doing well. I have heard you shouldn't leave the lights on all the time like I'm doing and I wonder why not?
Does anyone know what will happen to seedlings if they are under the lights full time?
