Noob Question

What if I killed the maltodextrin and didn’t use the dry yeast?

It’s not going to change the gravity that much, I still think you’re better off using the dry packet with the liquid yeast.

I’m nervous…can you tell?

Yeah ;D

In case you didn’t know, the first letter in RDWHAHB stands for RELAX.

It will be fine.

I strongly second this.  Though scrubbing hardened wort off your walls and ceilings is a good “life experience”.
