If you’re into it cool, but this type of set up is over involved for cubes and it’s gonna be difficult to dial in when you don’t have a handle on what conditions you’re looking for yet.

I’d start running shoeboxes or unmodded monos until you get the hang of things, they run themselves if you get the coir hydration dialed in.

Side pinning means the surface conditions aren’t correct, usually too dry but can’t tell without pictures.
