Hooking a inline fan to your HPS

[Harry Gypsna]

Yea I thought that would have been my problem. Ah right my inline fan is 4inch and my scrubber is 4inch well the attachment parts which stick out for ducting are 4 inches but the fan is about 6inches and the scrubber is to, if you understand what I mean lol. Ah nice one for the help buddy I think ill invest in two clip on fans thanks again

4 inch(the size of the duct fittings is the measurement that counts) fan and filter, got it... I think the 4 inch fan is about 175M3/hr, they are usually somewhere around that number. You may struggle to get enough temp control for a 600 in your size tent with that, but if you can get a bigger fan and filter when you can afford it, you should be able to struggle along til then. It is better to have a bigger fan which you can turn down, rather than a little one that can't keep up. I would recommend a 6 inch fan and filter for your tent when your wallet allows it.
Not having the heating on in the room where the tent is will help.
Where are you extracting to, where is the hot air going when you suck it out of the tent?

Increasing the size of your air intake into your tent will help to drop the temp a few degrees. Or there is the option of adding a second air intake which reduces the amount of drag/resistance on the negative pressure in the room.

If you can't mount the carbon filter directly ABOVE the reflector at the highest point of the tent, then yes do something like this:

Another way, is to build a box for your filter, have the filter in the box, along with the fan outside the tent, then your duct is going Reflector-duct out of the tent-box filter-fan out the window(or wherever you are venting to).
The box doesn't need to be anything fancy, just sealed up well, you could do it with correx or use a toybox sort of thing, or build it from plywood.
When you can afford a 2nd fan, that is the way to go, then you can have your smell control and airflow separate from your light cooling, with your light being cooled with air from outside the tent.
Growell has a how to about doing the filter box thing.
You shouldn't blow through the filter, it won't last as long and you will be bypassing the prefilter(the white fluffy thing) allowing the filter to clog up with dust.

I used to use the smallest carbon filter size, and I made something similar taping two 5gal buckets to each other with ducting out both ends. It worked just fine and allowed me to do just what you are describing here.

My mate did it with a 25 litre brewing bucket. Buckets FTW

We should write a book, 101 growroom uses for a bucket.

One inline:
Inside tent -> Scrubber -> Reflector -> Fan -> Out

Two inline:
In -> Reflector -> Fan -> Out (use on the same timer as your light)
Inside tent -> Fan/Scrubber -> Out (get a $50 day/night controller to maintain perfect temps)

So I will need two inline fans is it buddy? I cant afford another one at the moment. Could I just have my scrubber outside blowing instead of sucking? Would the scrubber work the same smell wise?

I'd actually recommend using it to "blow" instead. Putting it on the "cool side" rather than the "hot side" will keep your tent cooler. If you run the fan sucking the hot air out, then the fan will warm up and be just as hot as the air you're sucking.
