What exactly do they do? I'll have to check YouTube to see what exactly their function is, but it looks like something you could make with a block of plastic and a dremel or have 3D printed.

Or some panda film with a slit cut in it... Or anything else opaque for that matter.

well they cover but they also distribute water from a drip system over the whole cube evenly

Yep I see that, it looks like a cool idea. But you Did ask for cheaper alternatives.

I bought mine for 3.5 at hydro store. I'm DTW and these really improve even watering.
