Yes, the covering was a possible way to keep things in an open living space. Actually the reflector works quite well and it's more of focused light in the a room then actually radiating it all over the place. Just an aside.
I think in the future a nice grow tent would be very cool. For the short term I'll take your word
and do the basement area. Plenty of open area down there.
You mentioned wiping down with water ? It's a cement floor - but perhaps it's best to stay away from any cleaning solutions, particularly cleaning on a regular schedule ?
Otherwise thank you for your answers.
