Quick question about ventilation

Originally thought about going with the Growlab tent and instead got the Homebox XS, i love it. Got a really good price on it. Just a quick question about my setup here.

Going to run a hortilux super enhanced 250watt under the sun system 2 reflector/ballast. The sun system 2 comes with 4'' ducts on both sides to pull air through. I plan on buying the s&p td-100 inline fan thats rated ~100cfm, and running it through HTG's 4 inch scrubber. Anyone used their scrubber for their growlight? Says 4 inches, i'll probably just email them about that.

Anyways my question is, i plan on going filter->ducting->light->ducting->fan->ducting->exhaust. How do I put this fan in there? Can you suspend these things with bungee cords and then just attach the ducting to it?

My plan is a stealth grow using just autoflowering plants, first seeds i'm going to order are the easy ryders and run 3 of them in this space. Just figuring out how to get this inline fan installed. Thanks guys.

Go to their website, I just did. It show a few options for how to set this up. You won't need the filter early on and I wouldn't use it then. I have never grown easyrider but have heard that they don't smell that bad so you may never need it. I would also test everything, with the light on, before you put any plants in there and make sure that everything is OK and the temps are in your safe range. Best of luck with your new set up and your grow.
