keep a gap between roof and grow room if you don't want a hot roof spottable by chopper.

I had a loft tent. Although they are not tall they are workable with some training.

Thank you for the message and Smart aware advice.
Yes there is going to be a 4" gap. Which I could fill with rock wool or aerolite, if need.
My loft tent has been difficult. Height space and other. I want to be able to climb inside and sit amongst the plants. I can see all better then. Currently I have to rubberise my neck past spaghetti junction to see the back two plants. I look forward to new space. Despite obstacles that may or may not occur.

I am assuming you are across the way, but can you guys get rigid foam board? If you line your space with that and also line your rafter cavity, leaving some space between insulation and decking, it might pay off a lot. Use a double layer of two inch polyiso, it will be like R-50 haha.

Yes, I am across the way. Quite correct. I work in construction, yes, a good idea about rigid foam board ( celotex ) I know where to get me a whole lot, free of charge. We are at the end stage of a build. Lots of celotex gets skipped.

Nice 1 dude :bigjoint::joint::mrgreen:

I could slip between ceiling joists

That rigid foam board ( celotex ) is a great idea. Got me thinking... But now I need to figure how to get it past the neighbours. I most probably have to cut it up at work and squirrel it home in my work kit bag. And then slide between ceiling joists, I'm also thinking to cut up my tent and fix the floor and roof of tent (tack) above the lights. And use the sides of the tent with service holes ( extractor, elec etc ) I am thinking to incorporate the sides into the new grow areas sides. So I don't have to cut out the panda etc. And which can be fix directly onto the rafters. Now to figure out extra heat. My grow tent has 600 true watts and is 1.2 x 1.2 x 1.6. The new grow room planned is a lot bigger. Nearly triple the tent size. With the exception height which gains 300mm. I will only be adding a further 600 true watts LED. So 1 q board 600w and two mars hydro 600s which together total 540w
With the extra space and running two large fans, and having both carbon filter exhaust and fresh air intake. Will I create more heat than what my tent does now?
Sorry for the bloated message. I just wanted to give the full picture, that way I can hopefully get good advice. Which your previous excellent advice prompted my brain to think.... :joint::dunce:ouch!!

No, your fans should only add minimal heat to your tent.
I use a 6" intake and 6" exhaust and it keeps me around 80 even on 90+ days.
Once you get it nice and sealed, insulated, you will have no problems controlling your environment provided you have a/c, dehuey ect.
Good Luck!!

Thank you for the reply and advice.

Yes, I have both an a/c and a dehumidifier. What did you think of the added barrier ( tent material ) to be put on "ceiling" so first layer celotex, then tent material then the lights. I am looking forward to my new project.
The tent has proven not for me. Or not with the hydro system I currently have.

I live in the Mojave desert. Temps up to 115f in the daytime.
Local regs require me to grow indoors.
I use evaporative cooling. Even whole house does not use AC.
Cools by 20-25°f. The trick is to have a way to control the humidity....but if you live with high ambient humidity then evap cooling won't work for you.
Also being a former contractor, insulate the shit out of that space and see what your temps do with good insulation and decent air flow before you go too much further.

Yes, I am definitely insulating. Using celotex rigid foam boards. My dehumidifier keeps things currently in check and will have no problem with coping with the extra volume.

Thank you

Grow well :weed::leaf:
