Algae Growth

[dnewsome2]

Is putting perlite on top of your rockwool effective at preventing algae growth?

yes and no it's not like algae can't grow on perlite itself. if you're worried getting some reflective tape or better yet some mylar or something white that's waterproof and put it overtop of the rockwool like a poncho.
