I think the idea is great. The only observation that I made is with ur lighting.

I want to say first off that I LOVE Hydrohuts!!!! I currently have 4 of them. 2 deluxes, a standard and a mini.

The deluxes are used for flowering only and originally I used 3 X 400w HPMH Full Specs. 2 lights IMO is just not enough unless they are 1000w. Since then I have upgraded both of my huts to 4X 600w HPS (hortilux Super HPS bulbs).

I highly reccomend at least 3 600w lights. Keep in mind that you will not have room for your scrubbers and filters with 4 reflectors. Perhaps not even with 3. All of the stuff will have to be mounted externally.
