I’m using a 36W LED tube with 8 dimmable levels to suit varied stages of growth. Once they get a little older, I will turn on my 300W LED. I have two White Widow seedlings about 2 days old and hoping that running lights 24/7 for a few weeks until going to 18/6 will be ok? Here’s a pic from this AM.
Sure. Theyll be fine. Plants enjoy sleep, but they will live thru it. Actually i run seedlings 24/0 first week or so myself.
2 weeks here. Many people do the same.
