when to vent clones ?

Question.?
When do I open top holes on dome? When do I leave the top off?

It has root nubs maybe more don't want to disturb. Cut approx. 1 n 1/2 weeks gsc strain.
I remember from b4 it takes 2 - 3 weeks to root ready for trans and I vent the little top holes ?? And at about week 2 n 1/2 or when roots are showing I start leaving the top off most time.

I crack the vent after I see roots, wait a few days then crack it more, wait a few more then take lid off. Just wait a few days between every baby step. Good luck!
