ive got a two stage ventilation system, one for the light and one for the cab. however i forgot to cut two outake holes, therefor ive only got one. If i channel both ventilation systems into one outake, will that cause a problem? Or in other words, is this plausible? I think it would cause a reduction in the airflow, but i dont know if its significant enough to impact the grow. any help would be nice, thanks.
