Slop Sink - Using Tupperware and lightproofing PVC?

I've got a drain in my soon to be veg room, and planning to route all waste water to it, dehues, mini splits, flood tables, etc. Here's a picture of the drain, and a quick, non-detailed glimpse at the layout.




I think I can T off the drain line so that there is a "slop sink" in both rooms. This way, I'll only have to worry about light-proofing a single entry point, the 1 inch PVC that goes through the wall to the flower room's slop sink. Like this;





The smallest, cheapest slop sink I could find was like 45$.. for basically a 12x6 plastic container.. Thinking of using a little tupperware container with a bulkhead fitting attached to the bottom of it as the 'slop sink'. I'd just build a small frame around it using spare wood laying around and mount it to the wall. You can get tupperware for like 5$ or less, so ~10$ for both slop sinks vs ~90$. Any thoughts?

And any advice on light proofing the PVC? Would using grey PVC help with that? I'd imagine the white PVC would let light through, even if just a faint glow.

Flat black spray paint? Since it's for a drain perhaps black ABS pipe? Seal around the hole with duct putty.

Brilliant idea for the sinks. The bulkhead fitting you mentioned should work or I've used uniseals with pvc even on a curved surface and it worked perfectly.

They make 1-1/2" and 2" escutcheons to go around the pipe through the wall.
