So last night I went and fortified my cabinet to get ready for flowering. Every crack and crevice have been weatherstripped, and I even went in and sat in the cabinet to check for light leaks...all is good to go.
Yesterday was night one of flowering and so far no problems. The only thing is I messed up my timer and the light never went on in the morning as it was supposed to be. It had 3 more hours of darkness on its 1st night....is that an issue? On at 930 off at 930, but today I manually turned it on at 1230.
