Slowing down lights without flowering

clone taken from a mother @ 18 hrs of light, has to be taken to 14 hrs. of light once its rooted for what i need to do. Will this possibly trigger a flowering phase or just slow down VEG growth, which is what I hope to happen....I know it sounds crazy, slowing it down, but thats what i gotta do..... ?????Blessings

That is 100% determined by your genetics. I have stable Kush strains that would bloom hard under that light, and other varieties that wouldn't change much, if at all at 14/10.

Remember that plants to still grow during the dark cycle. Usually, an increase of light intensity will cause short inter-nodal lengths and you can top it and "keep it from growing too quickly" that way.

Also, genetics determines how much a plat will "stretch" after it is put int bloom. If you have an indica, it may not stretch much at all. Thus it may slow down. However if it a long-stretching plant like a sativa then your screwing with the light cycle may cause it to stretch faster!

I'm sure others will be curious, why do you want to slow it down?

any thing less then 14 hrs of dark will triger flowering..
