Alright well i have decided to construct a flowering chamber here are the specs. I plan on covering the interior in a mylar surface with a plywood exterior. i do have some questions though. How big should the intake/ exhaust be for it? what do you think? i will have to put off building this for around 2 to 3 weeks due to the fact i am going out of town. but when i do finish it i will be sure to post pictures Any ideas, praise or criticism is welcome thanks.

I built a box like that but used PVC pipe instead of plywood. Its about a foot and a half smaller on the length and width, but it is a little taller. My intake is 6" intake with a 4" exhaust, both have fans to aid in air flow. I am by no means a ventilation expert, just letting you know what did.

i was kinda thinking having 4'' intake and 8'' exhaust cause i thought i read you need more exhaust... donno though....... but what did you use for the structure exterior? the frame will be 2x4s connected with 3 screws at each joint. which comes to 66 4" screws.... then the plywood wanted to use a poly cover but that would cause more work meaning i would have to conform it to my specs...

I just used pvc for the skeleton of the structure and the panda film for the skin. You can check it out here https://www.rollitup.org/grow-room-design-setup/20779-pvc-skeleton-panda-film-skin.html

I got a roll 10'x100' on sale for $45. It normally runs $80-90, i think.

just remember make your exaust pipe diameter smaller than your intake as hot air is a lot easier to move where as cold air is denser and hevier

get your self a bathroom exhaust fan (home depot or lowes) would exhaust enough air to change it cut your hole to fit. and what i am using instead of mylar is thermal barrier
(again homedepot) that and a 400 what light should do you

You want your intakes to be 2-5 times the size of your exhaust.So for example of you were using a 6" exhaust fan, you should have at least 2 x 6" ( or 1 x 12" )holes cut for intake.

Good luck.
