air intake???

do you have any airflow?a fan inside it?

your not allowing intake of fresh air. it would be like be like putting you in a car and just letting you breath in your own breath.
 
u need an exhaust fan more important than a intake, for the intake u can just have an open hole and let the exhaust fan pull in fresh air...u need air flow my man, they say u have to move atleast 3x the amount of space u have in a minute..example....so a 3x2x5 room will have 30 cubic feet...u need atleast a 90 cfm (cubic feet p/ minute) of air transfer in there...

well then u do have an exhaust system out of a window, well then u obviously need an intake or u dont have any air source to exhaust out the window, u dont have to have forced air intake with a fan but it can be passive, have some holes or vents introduced into the situation, have them down low so fresh air can travel up past the plants... the plants def need fresh air to breathe
