Thankyou for your comments rusty
I didnnt think it would be letting much light in because the room in which the closet is situated isnt very lit during "dark" hours
Also ive used like insulation strips along the door edges to close the gap better. i'd imagine most of the light leaking is from the intake fan.
BTW this is my first grow, i have an old thread somewhere logging the start of the grow (you WILL laugh)
This time has mostly been about practice and keeping the bugger alive.
I have been believing my 250 was more than enough for a single plant?
D'OH!
Thanks again.
