Live Stoner Chat Sativa's 11/13 Dark Cycle - Does anyone follow this for Sativas?

[Kaiju]

I hear alot of people talking about Sativas having quite whispy/fluffy buds sometimes

Ive just been reading that true sativas have an equatorial light cycle which is 11 on 13 off when its flowering time apparently

I wonder if this could account for some whispy/fluffy bud producing phenos ?

What up Kaiju :smokebuds:can you give me a link on the subject i have never heard that......but i am just a JR in the game...:Cool:

 

[GCase]

Kaiju--In Rosenthal's Grow Book he describes all sativas as "fluffy." Of all the varieties they require the most intense lighting. With equivalent indoor lighting 11/13 would be near perfect.

He also describes a techique of going 10/14 the last few weeks of flowering to increase the speed of ripening.

Inducing Sativa
After many years of first-hand experience breeding herb indoors as well as outdoors, I am of the opinion that the two most influential factors involving phenotypic variation and expression among current indoor herb breeding projects are the photoperiod (hours of light per day) and the angle of light in relationship to the growing plant.
Specifically, I find the single most powerful influence to the Indica dominant phenotype is the traditional 18/6 veggie cycle and 12/12 flowering cycle. The 18/6 veggie and 12/12 flower cycle is an attempt, however poor, to mimic the Indica-producing photoperiod. It is my belief that this light cycle strongly influences for Indica phenotypic expression.
Sativa phenotype characteristics will manifest under a more equatorial photoperiod, closer to a 13/11 veggie cycle and an 11/13 flower cycle. This is the light timing range to use to elicit more Sativa dominant expression from your plants.
As for the exact photoperiod formula that I incorporate into my growing/breeding regime, this will presently remain a trade secret. My advice is to experiment with different photoperiods, keep good notes and pay attention. Avoid the 18/6 and 12/12 photoperiods, while tweaking the times a bit differently with each breeding cycle until more desirable results in the finished product and their offspring are noted. Here's a hint: work in half-hour increments or a little less, and good luck!

There ya go bro

thank you sir......:stylez rasta smoke:

Welcome - that website is brief i cant find the other one

Its to do with the areas of the world in which sativas grow naturally - this is closer to there natural light cycle so tends to bring out the perfomance of the Sativa better

 

[Balarama]

I think the fluffiness of the buds in sativas is more related to their evolutionary background than to the artificial light cycle.
I mean, many of the sativas are mostly equatorial with some exceptions, which means their bud structure is a consequence of adaptation to the climate, which is hot and humid in the tropics, thus more resistance to humidity than a dense bud plant would have.

Sativas are the cannabis adaptation to tropical weather and should be grown accordingly to their natural environment, 11/13 or 10/14 being a part of simulating the tropical light cycle.

From what I read, a lot of the fluffiness may also be a consequence of not ideal npk nute ratios, some growers pushing too much N in the flowering phase so the flowers stretch more than they would.
So for flowering cut the N and lights to get a nice ripen sativa harvest.

I am a novice, so the question may not make sense, but if the seeds are bred from plants that have been altered over many generations by breeding from the original photo cycles for sativas and indicas, would they still react in the same way a wild indica or sativa would?
With all of the genetic engineering going on today- with cross breeding and feminizing and auto flowering varieties, do plants still respond to the natural photo cycles or even have a single photo cycle dominance in their genetic makeup anymore? Or are there true natural strains that we still use?

 

[Kaiju]

This is what interests me my friend as the majority of strains available today are hybrids however the hybrids will carry phenotypes more towards the sativa or indica - so maybe the key is to use a sativa like light cycle when your hybrid shows more sativa tendencies - this is the curiousity

You commonly hear with a indica dominant hybrids when they give the possible phenotype information "the sativa phenotype poor producing, low height, low aroma" etc im thinking this is because that phenotype should of been grown slightly different

People say indicas are the stronger smoke - but maybe thats because we are growing sativa dominant phenotypes under indica conditions

And therefor via regiment we are losing favour in sativa genetic evolution? because we are out breeding it with indica purely because indica favours those conditions over sativa

To get the truly best mothers for clones or breeding you would have to take 2 lots of clones and place one with a flowering chamber of 12/12 and 1 with 11/13

Then you would truly find the most vigorous plants in their environment

Interesting thoughts Kaiju. You sound like a person w/ experience in the field. I have a photo AK48 growing currently that is supposed to have a sativa high but an indica body ... leaves are certainly short and fat and it looks like it's gonna be a bush. Are you saying that I should flower it under conditions that would be be more conducive to the type of high I'd prefer or ... to wait and see how the plant develops and if the plant leans indica to flower at 12/12 and if it is more sativa to give it 11/13 ... basically to allow the plant to 'tell' me which light cycle it would prefer ?
