400 w hps dr90 extaction?

hey peeps i ve got a dr90 400 w hps i'm wanting silent as possable grow. Any suggestions i was thinking rvk 5" with matching rhino filter. Will that do for sound an heat? I will add a fan controller if needs be. thanks

p.s should i get the L1 or A1

have the same setup tent and light .. i found if you run filter to hood (or cool tube) to fan to exhaust works the best .. with filter/fan inside the tent .. but keep an eye on your heat .. cant help you with the filter but the fan is pretty quiet


happy growin

The A1 is quiet. I use one as my exhaust/filter but I also run an RVK150L1 on my 600w air cooled hood.


That sucker is loud!!!!!

I would say get the 5"L1 you can always speed control it.

I wont be able to get cooltube just bought euro reflector. Do you think running the a1 without speed control would be ok heat/sound wise or is it better with L1 with speed conroller just cost me quite abit more to do it that way cheapest conrol i seen was 50 pound an am nt that gd with electrics
