relax @eltalia. No one, least of all me is accusing you of having sold me the box of bees.
I have read plenty for the past month (enough to make the conscious decision to build towered nucs). And I am sure their will be no end of more reading.
One of the things I have read and heard from multiple sources is to feed 1:1 syrup for a month after installing a nuc. Also, going into dry season with no knowledge of local flows causes me to er on the side of feeding.
Ultimately, the best learning is in the doing. I can see why you'd fear the worst. A guy with his first posts showing a non laying nuc in a towered nuc system feeding bees. I am a fast learner. Hopefully I can get through this first year without damaging too many bees or your optic nerve in the meantime
