18/6 would be more sensible.
Not 16/8... although there's no reason you can't do that.

I can't see the pics.
Can you upload here?

They have now... 8 days?
turtle420 Reviewed by turtle420 on . Seedlings Ok I have two seedlings. One is doing better than the other an I have a 3rd trying to sprout. PICTURE I had it on 24 hour light in the rubbermaid grow box. I'm only using the top 1/2 of the box since it's just seedlings still. Those two are from August 20th. They seem to be growing slowly. Should I bump it down to 16 hours of light and 8 hours of darkness? Rating: 5
