NEED ADVICE ON DARK ROOM & VARIAC

[DeJa]

ive got a 5'x5' dark room. 150 cubic feet

gonna put about 1200watts at least

im wondering what size fan i should use can33 or 66?

i want to run the fan under capacity at all times with a variac controller

can i use a variac to run the fan at 40% 12 hours and then 70% for 12 hours?

I dont see any problem doing that.

on the variac is looks like it only has a knob for one speed..

can i get it to run different speeds at different times?

 

[Stevius]

Hmmmm... usually with variac you control how much currency will flow.

To run at different speeds at different time you would need a timer also.

Are you using aircooled reflectors or cooltubes? because its gonna get hot in there unless you cool those lights somehow...

im gonna be using a growzilla dual bulb air cooled hood


with two 400w bulbs ONE MH - ONE HPS


If I ran the variac with a timer, would i have to manually adjust the variac speed everytime i want it to change?

Basically.... yes or you can make an micro controler and program the whole damn thing so that it will grow all by itself

i decided to go 600 hps & 400 mh

so where can i get the newest variac?
