Light Leakage in the dark period??? Need to know ASAP!!!!

hello everyone, okay here's the deal i have one room i'm restricted to so that i can grow in general, the areas about 12x12ft. i have one flowering tent that is 4x8 i leave it open because of space/heat problems, i have my babies anywhere from 72-78 degrees at all times. It works perfect and have a fan blowing perfectly in conjunction with an ac unit. All my new air is coming through the opening of the tent and have the openings of the tent open to about 90% unzipped. LONG story short this is the best way for now. I am adding a 4x4 veg tent that will remain zipped up at all times and i'm only using a 2x4 t5 8 bulb unit. This tent will be much easier to ventilate since the heat of the unit is dramatically less. Will the leaking through the zippers affect the night period in the flower room??? the rest of the room will be completely dark. I know that all these tents aren't completely light proof and i'm a little worried. Any help would be appreciated!! Here's a small pic of how the rooms are alligned.

light leaks are fairy stories...female pot grows outside since the dawn of time without going all hermie just fine

duct tape can easily cover zippers for the paranoid however

i totally agree with chubby soap. in my setup i have it in the pantry room. theres nothing to cover it at all and every so often (pretty much every night) my wife or myself go to the kitchen to grab something to drink and theres always light being leaked into the pantry room and mines have never hermied on me. just make sure that the light is not as bright as the sun or the bulbs, other than that youll be fine.

Ever see how bright a full moon is? And that doesn't trigger photosynthesis....

Thanks fellas, best buds love your quote!! lol kool sounds good i'm just being a little paranoid i guess, plus i heard that if they are used to it from the beginning of flower then that's what they know is dark.
