Just An Idea...

First time grower, and am now in the 3rd week of Flowering with my plants (White Rhino and UK Cheese), and am as we all know on a 12 - -12 rotation. As I was reading Uncle Bens last post(and very informative it is too, thank you UB), I had a thought. What if instead of a 12 - 12 cycle, I changed to an 11 (light) and 13 (dark) for weeks 3 & 4, and then changed again to 10 (light) - 14 (dark) for weeks 5 & 6 ? THen convert it back or leave it the same for the last week or two (haven't yet thought that far). Would this in any way shape or form increase the yeild or speed up the time taken to flower ? Would love to hear your thoughts on this. Thanks

Bad idea.

Do some research and read why.

My advice. Stick to what works

I want to see the research you've done.


Plenty of professional breeders and growers have grown
in different light cycles, such as D.J Short, and Soma, and Jorge... These
breeders know where their strains come from geographically
so they can approximate the amount of daylight they would
naturally receive. With Sativas you could benefit
from an 11/13 flowering cycle... Although switching from 11 to 10
back to 11 and such is not a good idea, if anything only keep shortening
the light cycle, never make it longer, this will confuse the hell out of the plant.
but starting at 12 and moving to 11.5 and then to 11 wouldn't be
a bad idea with some Sativa.s

Have at it then.

i would just do the 12/12 my self. really dont see how it could improve your yield or speed it up the process in any way buy changing . but good luck

This isn't research, you read a snippet in a book. Go to class... I've never seen
any reference towards photoreceptivity in an R.C. Clarke book anyways.

The 18/6 - 12/12 indoor light cycle was created specifically for Indica Dominates.

Sativa strains can and do vegetate at 13/11. and flower at 11/13.

The two most influential environmental triggers for phenotypic variation and expression among current indoor herb breeding projects are:

1 Photoperiod (a.k.a. photo receptivity, light timing or dark period manipulation)

2 Angle of light in relationship to the growing plant.

Specifically, I find the single most powerful influence to the Indica-dominant phenotype is the 18/6 veggie and 12/12 flowering cycle. The 18/6 veggie and 12/12 flower cycle is an attempt (however poor) to mimic the Indica producing outdoor environment (photo-period). It is my belief that this light timing cycle strongly influences the Indica phenotypic expression. Photo periods at the equator would be closer to a 13/11 veggie cycle and an 11/13 flower cycle.

The exact photo-period formula that I incorporate into my growing/breeding regime will remain a trade secret, but my advice is to experiment with different photo-periods, keep good notes and pay attention. Avoid the 18/6--12/12 photo-periods while "tweaking" the times in half-hour increments or less with each breeding cycle until more desirable results in the finished product and the next generation of offspring are noted.

way to dominate shrubs, i like your style

i also like the argument stick with what works. why try and be different when 1000s of successful plants have been grown 12/12?

He wasn't referencing photoreceptivity, but rather resin/THC production with a 10 hr light period.

Good idea to keep good notes.

A very good phrase I've heard over and over on this forum.

"Don't try and fix what isn't broken".

Leave it at 12/12, your babies will yield as much as they can. Don't go and try experimenting if you haven't been growing for years and especially if you can't afford to mess up your crop.

Good luck,

Thank you all. You can all relate to your very first grow, and your mind works overtime awaiting the yield, the quality, and the concern of, "can I do it better like this....?", and all those what "if's". Advice appreciated greatly.....I've got a thousand more crazy ideas, but I think I'll read up on them first.
