Hey everyone, I’m a noob to the forum and to growing. I currently have 5 northern lights seeds germinating in a damp paper towel, after about 36 hours 4 have little root tails, one has yet to pop. My main question is once they’ve germinated enough to plant, should I start off with the 18/6 light cycle or would seedlings benefit from 24 hour light for the first week or two? The 5 seeds will be going in to 5 gallon air pots with fox farm’s bush doctor coco loco in a 4x4 tent with a Viparspectra 900w LED light 32” above the pots. I actually have two of these lights but I was gonna wait until the plants are like 4-5 inches tall before I add in the second light to see if the extra light would help or hurt them. If anyone has any recommendations about the light cycle or changes to my set up I would greatly appreciate it. This is my first grow and I welcome any and all advice, thanks!
24 hour light for seedlings?

you can certainly run seedlings on 24hrs i do it all the time for laziness more than anything but a plant will sleep so running a 24hrs on schedule is a waste this is what iv been told so 20/4 or 18/6 is the recommended times

Agreed. 18/6 is better I think. I was running lights longer but my plants were getting tired and laying down early so I moved to 18/6. One of my strains could benefit from 17/7 I am sure as she still goes to bed early.

I run my veg lights 24-0 and have for over 14 yrs. Seedlings stay under a T5HO for 3-4 weeks awaiting their rotation into a bloom tent. None have ever complained of lack of sleep.

Great! Depends on strain. I have plants that could stand more light. I have plants that weep near lights out. If his plants are shutting down b4 lights out he is just paying for electricity unnecessarily. IMO.

What is more important at this stage of the plants life is PAR. You may want to google that term and learn about light intensity.
24 hours at 1 foot will burn and 24 hours at 6 feet is worthless ( get my point?).
Study and get this knowledge down pat, then worry about light hours.
Once you understand the plants needs for light, then you can start increasing the intensity and shorten the hours.
Causing better growth through efficiency and at the same time shutting the lights off and saving cost in electricity.
Think about it?
