sealed grow room question

how do you seal the doorway to a sealed grow room to make it airtight?

superglue??
sorry,rubber weatherstripping all around the perimeter of the door works- it wont be 100% but I dont thing anything short of buying a hermetically sealed chamber would be.

they sell doors things that block air for saving energy. Like when it's cold out side and the heater is on, it blocks the air so your heater is not always on from the cold air getting the the bottom. There like 9.99. cant remember what there called!!! Try google man

i understand wanting to seal ur room/area to avoid light getting in or smell gettin out but do u have an intake for fresh air? i use a tent but it has little flaps at the bottom to allow passive intake. ur plants have goota have fresh air buddy.

i have been asking elsewhere about building a sealed room with co2 and i thought that i would need an intake but was told by an old hand at sealed rooms that a sealed room with co2 should not need any air from an external source as the plants use co2 to produce oxygen as a by product of photosynthesis.

co2 = no fresh air, not even at lights off wen u aint using co2..
some ppl do use intake and exhaust with co2 to control temps instead of AC but obviously some co2 is wasted..

There is a thread on verticalgreen.org about this somewhere. Hold on...


Here ya go. It looks like this guy made a sort of air lock into his grow room.

You can also see his grow journal here, i think there are pics of the setup.

thanks proheto.
I have been pondering "a perfect room" which doesnt have an air intake or extractor outake.
I have read that they are not needed if you run co2 at 1500ppm and then turn the co2 off on lights out, the plants are supposed to be able to make enough oxygen for the dark period to keep the room good but it doesnt sound right to me.
