What is the moon's light equivalent?

Sean Tom · May 2, 2012

Ok so i know that it is always key to have complete darkness during the flowering stage. However, i was pondering on outside grows and how the moon is present when the sun goes down. So my question is can the plants actually have minor amounts of light during the dark hours or no and if so how much light is too much.

very good question actualy.
Not much i guess because flowers outside take it darkness

Indoor strains are apparently more sensitive to light in their dark period than outdoor plants. Possibly because they tend to be flowered when they are less mature.

You can also, apparently, allow some far blue and red light without disturbing the nightly hormone build-up needed for flowering. I personally think that the tiny potential increase in yield (from giving plants a little light at night) is insignificant compared to the pretty serious risk of getting stunted or hermaphrodites buds and ruining your harvest if you get it wrong. I'm sure others take the risk without a problem, but it's not for me.

anything brighter than a full moon will mind-fuck your plants. watch out for street lights

and most of the time, weed has a canopy of larger foliage over it. That helps block some of the rays.

ty much appreciated. i didnt know outdoor strains and indoor strains differed that much. thanks. ive never actually grew outdoors but am considering it this season.

i actually saw an outdoor plant and one half of it was flowering good and the other half still vegging because of a street light. great tip

seems legit

thanks all for your input

Invest in some 25W green light bulbs in case u need to go in there when the lights are out. I use 3 x 25W green phillips normal fit lightbulbs in case I want to have a night visit !! Green light is not absorbed or recognised by plants.

Sean Tom · May 2, 2012

yes thank you. i am actually aware of the green light thing. was just interested in knowing how much light just because i started thinking and like i said the moon is light, but thanks

Moonlight is natural and it is a different spectrum so no worries !!

moonlight is not a differnt spectrum it is simply a reflection of the spectrum emittied from the sun, with that been said it is a poor reflective surface, most of the spectrum is absorb or redirected in to space, what usable light is sent to the earths surface is to weak to be of any use to most plant life, but all the parts of the suns spectrum are there,

Indoor and outdoor plants are the same, lol, the only thing that makes a plant an "outdoor plant" is that they tend to be larger strains and alot of them would be more mold resistant.

The reason we run absolute darkness is purely about having completely optimal conditions, trying to match nature is silly, we can do so much better than nature alone because we have more control.

Sean Tom · May 4, 2012

thanks harrekin makes sense. optimal conditions

idk, i get into this one a lot when i always read people saying that light leaks cause hermies, and i point them to outdoors and the moon light like the op is talking about..
obviously, large amounts of light during lights out are going to have a huge affect on flowering.. someone mentioned street lights and half a plant flowering and half not because of street lights.. but i have yet to encounter a hermie with smaller amounts of light in flower..
i grow in a small closet set up and i tend to leave the door open all of the time to keep temps down.. i usually run the lights at night to keep the temps down, so that means for me lights out are during the day hours.. i'm not saying i get huge amounts of light in my grow, but it sure as shit isn't pitch black either, that's for sure..
i have heard people saying that the small led on some grow equipment is enough to make a plant hermie, and i say bs, as my power chord is lite and i've been using the same one for about 4 years or so now, and not one hermie has been seen.. i grow anything from regular seeds to fem's as well..
i'd love to know exactly how much light is required to create problems, but ime, smaller amounts of light will not hurt nor interrupt flowering ime..
