8x8x8

going to cut in half one side for veg one for flower. inbasement thats not finished what would be the best way to make a ceiling trying to get a rough idea of about how much it will cost have most equipment but one light and a t5. gotta get the lumber and drywall/plywood. which eber is better.

If you could do away with drywall altogether it would keep the temps lower. It is a bit more expensive to replace wallboard (Sheetrock) with a double layer of 3/4" pebbled Mylar coated white polystyrene foamboard but it has much less mass (less mass=less heat retention) and does a great job of confusing infrared sensing devices when negative pressure is achieved with your ventilation configuration.You would still use wood studs for framing and support of the various appliances (lights, fans etc).

You have a very nice ceiling height. Take advantage of this by avoiding direct contact of the wallboards and studs with existing framing (except for a few vertical stud ties between the new framing and the existing structure) If you create a gap on all six sides (including the floor) of the split veg/flower rooms you will completely eliminate any chance of conductong heat into the inner walls (as long as you have negative air pressure) of the house structure and this air gap will also greatly reduce heat transfer from the house into the grow room. I apologize if I made it sound confusing, but this type of construction is actually far less work to accomplish than typical drywall construction.

If you choose to do it this way just try to leave an air gap between the veg and flowering chamber by framing a stud wall between with a double layer of the foamboard on each side. This will keep it completely light tight so neither room will transfer light to another. You could make the air flow through a perforated floor if you achieve an air gap between the grow room floor and the existing floor. Then you could place your exhaust inlets above each light to suck heat from the sources that create it. Don't worry if you need to bend the duct to achieve that. As long as you split the main exhaust trunk into many inlets (one duct with an elbow above each light so that the total sum of the square inch area of those inlets is far greater than the area of the exhaust diameter, preferably 5x as much if each one has a bend)you will overcome the friction losses that occur when placing elbows or offsets in the duct work and there will be no restriction of the total cfm output that your exhaust line can handle.

I built an 8x8x8 Pretty much like you describe

Use fire board or drywall for your walls and ceilings. It could save your house from burning down.

You can also make the room pretty much airtight with drywall. Keeps smells in one place or prevent foreign objects from entering your environment.

Plan all your wiring, duct work, and climate control options i. e. Run a sub panel or designated line to the room for your lights etc.

Frame up the room with 2x4 studs 16" on center and make sure to insulate with r-13
Put up the Sheetrock , paint the room with a high quality flat white paint. Like B.Moore Aura is awesome paint it diffuses the light amazingly.
Install a pre hung door and trim. So it looks like a closet from the outside.

And you'll have a cozy little spot for your shit that looks like and is a legit room, like a closet or a bathroom.

You are gonna spend $600-1000 for materials and a lot of labor.
