I can seal the box completely So airflow is a no no for the duration of this period. Recently I moved into a new house and the last owners had FIVE Labradors. Thanks to them and the lazy cleanup crew we have a flea infestation. So the landlord is having a guy come in to spray the house with some like serious shit. We cant be in the house for 2 hours. Will this in any way effect my plant? Also. My grow box is rather... well NOT hidden at all by any means. So I have to transfer it to a temporary box but it won't have any light for about 2-2.5 hours because I don't want the guy narcing on me or something. I started 12/12 cycles exactly 1 week ago (Friday, When they are spraying it will be 9 days) I have it set light on during the day so during the night no light will be there to screw the plant up. Will that extra 2 hours or so of darkness send it into shock?
