So I'm currently ordering materials for my new grow room. Ive had to move outside due to space issues :L which isn't ideal but it is what it is right?
Soo I've brought myself a 6x10 shed..
The plan is to wrap the outside of the shed in that tinfoil bubble wrap stuff it acts as a vapour barrier and also keeps heat in/out. Once the sheds been wrapped I'm going to go round it with 25mm batons every 300mm and between them have 25mm cellotex. This will then be boarded over.
Inside, there's currently 25mm struts every 300mm (as to hold the shed up) my plan is to fill these gaps with rockwool or similar insulation and then boarded with 12.5mm plasterboard.
It currently has a slanted roof, again the plan with this is to make a flat roof, then have a pitched and tiled roof ontop of the flat. This will be a dead space and part of the passive intake. <any reason not to do this?Hopefully making the roof appear the same temperature as outside.

My rear garden is just patio slabs, so my plan is to lift a line of these from the shed to the house. Run my power cable and a hose pipe, and also some 4" ducting for the exhaust fan <not sure wether to bother with ducting as I intend on running cobs

I'm not sure how to set the room up, ideally I want a flower and veg room (was originally going to do two 3x3 cabinets next to each other) and then a cabinet for clones/mothers. When I thought about it though, if I did two 3x3 cabinets next to each other I wouldn't be able to access the plants at the back of the flower room should I need to check them (going to be scrogging)
So now I'm thinking two cabinets on opposite walls (10ft length sides) these will be two 2x5 Cabinets and a clone/mother cab next to one of them. I'll ad some crude pictures in a second to further explain what I mean ;L

LIGHTING
Then about the lighting.. Been researching cobs now for a couple of months, but still don't really understand them fully knowing to find/source all the parts Id need has been a ball ache...(The trouble is choice I think) Ive stumbled upon rapid leds and looked at their diy kits (quite like the fact they've collated with growmou5 I'd much rather go over kill then not have enough light. The kits I'm looking at are for a 4x4 area one option is using cree3590s and the other option is Bridglux vero29s
The cxb3590 kit comes in at 909 dollars and the vero29 at 749 dollars.. Im aware that cxb3590 is better hence price, but I'm thinking of going for the vero29 then adding a they're far red kit, so working out almost the same price.. What would you do and why? Can I source a 12 cob light in parts much cheaper then that, still using mw drivers and cree or Bridglux cobs?
Sorry for the essay
