How dark so no hermies


New Member
So how dark must my room be so I don't have problems. I'm growing femanized seeds, soil, Humboldt nutrients, greenhouse grow and have to move to dark room, can I just cover or is it worth the time to move to complete dark room? My plants are tall already.

Well, people say "the full moon is pretty bright," but it isn't, really. And most nights there is even less light.

When setting up a grow room, I wouldn't aim for "pretty dark," I'd try for DARK. Not just because of the chance that the screwy not-quite-dark environment will produce more hermaphrodites, but also because I'm not a fan of leafy bud. Also, because I tend to use the 40:60 rule for determining harvest dates and screwing up the cycle screws that up, too.


noun: dark; noun: the dark; plural noun: darks
the absence of light in a place.

In terms of how dark should the "night" cycle be... Well, you cannot go wrong with "darker than six inches up a well-digger's arse at midnight" (although why he would be plying his trade in the middle of the night always escaped me, lol).
