if you need 12 hours of light and 12 hours of dark dose it really need to be pitch black? is it ok if its a lot darker then wiht the lights on would that still work cause it its could replicate outside the moon wll still cast light so technically do oyu really need pitch black or could i use a whole lot of dark put with some very very dim light a lot darker then with the lights on???:sleep:

You definitely don't want a bright light on role playing 'The Sun' but a tiny bit of light will not affect the plant..

it has to be total and no red led lights like on a power bar or space heater or you'll get hermies.

it will hermie 9 out of 10 times,some genetics are tougher then others but why risk it.i dont know the science behind the moon i just know even the slightest light will hermie them.not green though.

Yes but Jorge Cervantes (a really pro-grower) sais it´s ok to use a green light cause they don´t trigger the hormones.

is it ok if its a lot darker then wiht the lights on would that still work cause it its could replicate outside the moon wll still cast light so technically do oyu really need pitch black or could i use a whole lot of dark put with some very very dim light a lot darker then with the lights on???:sleep:
I read the plant is really sensitive on lights so if u want light go for a green one.
Have a nice one bro! :blsmoke:

why risk it. just make a cardboard box and make sure no light can get in. or tape up stuff around the table so its dark. a little light doesnt hurt your plants but you can get hermies. the light from a bulb is also a differnt kind of light, than sunshine reflected off the moon. just build your self a dark box with cardboard snd duct tape.

the moons light is not seen by the pplants. you want it as dark as possible

It dose have to be dark as you can make it but a lil light is not that bad. With good strands you want to go by the book. bongsmilie

Moon light is typically under 1 lux. So if your source is also under 1 lux(measured at the plants), you'll probably be fine.

Some plants rely on the moon light. And some greenhouses simulate moon light for certain plants.

i agree it should be a blackout during ur dark period but strongly disagree with ppl sayin a lil light bar can turn a plant hermie..dont believe the hype find out for urself..and just a little trick i picked up, during ur last week or two of flowering give ur plants 13-14 hours of light with less dark and ur buds will blow up..what the extra hour or so of light will do is force ur plant to use all of its remaining sugars etc. to produce bigger buds

Interesting. Not that I don't believe you, but I never heard this before. Would like to hear it confirmed by other growers.

I imagine that combined with this:

in the last week of flowering could result in a fantastic technique. Maybe the 21:36/12 might be modified to some more convenient number of hours/minutes.

complete dark for plants is recomended. star light is too far away and travels through cold space. its usable spectrum is absorbed by space as it travels, star light only arrives on earth one photon at a time. not usable for plants- moonlight is relected sunlight but is not the same as light being relected off your MH or HPS hood. It has something to do with the moon is not being smooth and the reflected light looses a majority of its spectrum if it isnt from a "pure" source. some degree of light has to be ok. where that degree is, i dont know. all i know is for the time and effort i put into this i wouldnt let a firefly or a nite light near my plants after lights out. out of all the things you have to control to grow successfuly (light, heat, nutrients, PH, watering schedules, RH) getting it dark when it is supposed to be has to be the easiest by far.

i just checked out that link and i think it is ABSURD. I can think of no circumstances or logical reason that a 21 hr and 36 minute light peried followed by a twelve hour dark period would work. its almost like an 18/6 veg cycle.

who knows, maybe it'll double your yeild!! someone should try it (but i'm not risk'n my ladies on it.

Why "ABSURD"?
It is definitely very different from 18/6 because the dark period is full 12h.
Also consider that ATF doesn't/didn't get even 6h of darkness and is reputed to be the best weed of all strains and times.
The author claims his technique is a result of extensive experimentation.

interesting... you have done this and it works? i would think the reverse would be true, mimicing nature would dicate that the days get shorter as the plant is flowering and speed up the process so it finishes before it dies. i thought plants created and stored energy through photosynthisis during the day and utilized the stored energy at night to grow? if you have done this and it works i'd give it a shot. how much bigger did they get?

i have grown plants 12/12 from seed with no veg cycle with great results. they dont "need" a veg cycle. and as far as the author claiming his technique is a result of extensive experimentation is fine and dandy, but until i see a grow with pics i'm not gonna try it. would you? If somebody claimed they did a bunch of experiments and the results said it was good to water my plants with vodka and orange juice i'm not gonna try it, i'm gonna think its absurd. show me a grow with increase yields from it and me and the ladies will be getting hammered on screwdrivers! and im not saying you are absurd, but that idea in that link seems to be. all i'm saying is it doesnt make sense... the only places on earth that ever gets 21 hours of light is the north and south poles, and nothing grows there. The equator gets 12/12 and thats where the lushest vegetation on the planet is. try it, if it works out and you get an improved yeild i'm on board. until then, it seems absurd. the earth is still flat, right???
