Hi Guys,
Anyone use these for passive ?
I"be seen them on EBay and are a bit expexpensive,but the way they are designed with a kind off built in light baffle on the front looks very good.On reading about them,it says the front battle plate is to stop wind gusts from outside, so they are obviously not designed for a grow room,but look ideal to deal with light issues.But will this built in front plate/baffle,restrict the much needed airflow for a grow room,OR the grow room where my 400 HPS resides! Lol...???
Any thoughts on this Guys?
Regards
Steve
