Week 2 of grow and I need some advice

Hello, I have a few questions I need some help with;

  1. Should I run my exhaust fan 24 hours?
  2. Is 12/12 okay for new sprouts?

Yes to fan

You need to have air exchange for fresh air all the time

And if they’re autos 12 /12 ok although I’d go 18/6 whether they are photos or autos personally

If they’re photos you don’t want 12/12 until you ready to flip to flowers


Thank you Mr_Wormwood they are autos, I will take your advice and do the 18/6 for now

You’re covered, and welcome!

Yes indeed stay on 18&6 until finished
