since many have heard me rant in here about stray light not affecting your plants during their dark hours, I decided to post this, just to show I'm a little less crazy than some imagine ...
yesterday while thumbing thru my copy of Mel Frank's Deluxe Marijuana Grower's Guide, 1997 edition ... I accidentally came across this: " the amount of light needed to prevent flowering is quite small (about .03 foot candles - on a clear night, the full moon is about .01 foot candles). However, each plant must be illuminated fully, with the light shining over the whole plant " ...
OK, what I mean to illustrate by this is, yes, you want the dark hours dark, and uninterrupted ... BUT, sometimes I see new growers that are frantic about sealing up an airtight cabinet, etc ... its just not something to worry about ... a clear, full-moon evening is almost bright enough to read by, yet it is only 1/3 of the light required to affect your plants, and then, only IF they are bathed in that light over their entire structure ... yes, keep it DARK, but don't stress yourself over it ... hope that explains why I frequently say " what?, isn't there a moon and stars in your world ? " ...
