I'm 2 weeks into veg with 4 Strawberry Cough photo fems. This is my third grow overall and my first with Autopot. I am running a 4 cloth pot system with a 50/50 mix of super soil and perlite. so far so good. I'm adding Regeneroot in the rez. No other nutes. I've noticed that the top 1"-2" of the soil in each pot is really dry. I don't want to top dress with nutes as I'm wanting to see how the super soil does throughout the grow. My question is this, should I put something on top of the soil to keep it moist? Or am I concerned about nothing?
