Will plants still flower if the lighting period is somewhat different every day, say 12 on 13 off 13 on 11 off just small differences?

whats the shortest i could flower plants for?

how many feet should a 1000watt hps be from plants.

also do the plants defiantly need fertilizer or will they still be fine without it.

thanks

I have been told that small differences like that can drive them nuts and make them go hermie. Just what an expert grower said to me.

thanks for the response, what if there not in complete darkness? say a pin prick off light is getting in?

Well, it needs complete dark but I am thinking that moonlight is pretty normal in a plants life. So, unless there are posts otherwise, I would think that a tiny amount of light will not make a huge difference. However, they do work in the complete darkness and that is what people have found.

yeah i was thinking about the moon also. its just so hard to get complete darkness where i am its almost complete tho

You can use black plastic and make a frame for it, but again, you can look at this as an experiment too and if they do just fine then you have discovered something new. =) At the very least, new to us!!

Anything but consistant photoperiods is likely to incur hermies.

But thats on the way to feminizing....thats not so bad. =) Always a bright side I say.

so hermies can re produce? so wouldn't all plants in the wild be hurmies if slight light from the moon would cause this?

hermies can reproduce and if done through a couple gens of hermyism, you can create a stable fem seed. now as far as light goes, moonlight works differently on plants than sunlight, the moon provides a spectrum not utilized by the plant. therefore, its BEST for complete darkness. as soon as some light hits the fans, the photosynthesis process starts again, causing stress on the plant
