Can you switch to 18/6 soon as the seedling pops up out of the dirt?

You'll burn up your seedlings with 24 on. They need a break just like anything else growing. Plus, It'd prob induce stretching.

Either is 100% fine, it's purely a personal choice and many great growers use both schedules. The seedlings don't "need a break", nor is growth significantly different except maybe slightly tighter internodes at 24 hr light. I use 24 hr light during the winter when I need more warmth, then use 18/6 in spring/summer to save on a little electricity.

I decided to put these new seedlings under an 18/6. Ive done 24hr with no problem for 30 days , but i had an auto seedling die within a few days of 24hr , it was not happy.
Thanks for the input everyone, cheers (:
