An experiment in regards to stray light and light cycle interuption...

[Methyl3]

I am going to be conducting a little experiment over the next few months. The basis for my experiment will be how much light is needed in order to interupt, stress and revert the flowering plants back into veg growth.

The reason I am doing this is because I always see posters asking about absolute darkness and flowering. i have also seen it stated in various books that grow area MUST be kept completely dark.

Is COMPLETE darkness needed or is it just another optimization factor that is ultimately enhancing rather than critically dependent?

Why must we have complete darkness when plants have grown in the wild for thousands of years with all types of natural/artificial light pollution during their dark periods i.e. moon, stars, man made light pollution?

How long does the period of exposure have to be in order to induce this reversion? Does a a short exposure just stress the plant and possiblly induce hermaphrodism or does even a short exposure cause a reversion and if so what is this time frame?

Is this exposure rate, if indeed applicable, variable according to strain and stabilty?

these are some of the question I am hoping to answer. I will be conducting these experiments on clones so we take away the variablity that would come from different plants of the same strain. I will also be using and extremely stable strain. Any suggestions would be greatly appreciated as I am leaning towards an Afghan #1 strain since it has been around a long time and very stable.

I would also like to know if there are any people that have relatively good light meters. I would like people to take measurments of the outside light on various conditioned nights i.e. cloudy nights, clear etc. I would like to get a sample of the conditons from various parts of the world since the enviroment in one place could drastically differ in another i.e. cambodia's summer is not like south africas summer. Once I ascertain the data from various growers I could then avg them out by categories and come up with a baseline. This baseline would be a point in which Mj plants that grow in the wild would still be able to sustain a flowering cycle in. I am aware that this could be a strain dependent factor, but we will start here and them elaborate as time goes by.

Clones would then be subjected to various amounts of induced lighting exposure during dark periods of flowering. I am also taking into account that a possibility might be that direct light ray exposure or non-direct light ray exposure could also be a factor on whether reversion is obtained or not.

Any further suggestions on how the epxeriment should be laid out are welcomed. I think we could learn some valuable info from this. If anyone is aware of something equateable to this being conducted on MJ plants then please direct me towards it. I will then try to branch off of the info found from their experiments or will conduct nothing at all if a position either way has enough supporting evidence. thanks:thumbsup:

does no one find this experiment interestring enough or am I treading on a redundant matter that no one cares about?

Way to go man- It's awesome when people actually try to experiment with shit. So, Kudos.

I'm very interested to see what you find. Good Luck!!

It's very interesting, but a complicated set of questions, so hard to respond to.

One additional piece of information I would like to toss into the mix- What is the light spectrum of the various sources of light pollution? For example, say a plant grown in a highway median gets exposed to car headlights all night, what does it do? Flower normally? Go herm? Fail to set bud? Compared to a plant grown at the edge of a parking lot with light from a distant HPS...

Your 100% correct. I have thought of this, but didn't lay out every possible question due to length of the post. Point is that we have to start somewheres and as we narrow our conclusion possibilities down, more experiments will have to be conducted. I figured if I could get the ball rolling we could have other satellite experiments conducted that could either support or weaken certain hypothesis.

In regards to your point...I approached the thought this way: Plants absorb almost all of the spectrums of light except green. Now what spectrum is responsible for reversion or stressing has to be determined at some time.

For anyone reading this post, PLEASE do not think this is something that will be accomplished in just a month or two. Hopefully with the help of some other growers, ascertaining necessary data will help accelerate the experiments. This is why I asked if anyone, from anywhere, could help with with the light measurements of your area. This data might not be applicable at this moment, but at some time it will.

If anyone would like to help and has questions on how to proceed please post on here and if need be we can correspond through email or IM. :thumbsup:

I'm working on interrupted and irregular light cycles right now, if that helps any.

Without a doubt! Let's touch base and see where your at. I could then possibly refine my direction if you can provide some data that would be applicable.
Send me your email and we can converse over that medium. Once I get started I can post some updates on this board

night-time film exposures can be shot in as little as 15 seconds (moonlight, clear night) or 20-30 minutes (just starlight) that's not a lot of light, the light at night renders few colors and contains little "usefull" light for plant growth. This perhaps explains the "effect" of night-light has on things; There are a few flowers that only bloom at night, but that is regulated by hormones, not the light directly.

would be very interesting but i feel there area few factors that will still nto be covered, things like the strain, i mean some strains may be more prone to light stress then others and the amoutn of light you're going to let it, lets say you measure it in hours of light exposure, one plant may change at the one hour mark but it's too hard to get an exact measurement i mean minute wise you know?

Interesting though
