Ok i have a white widow clone. It is my first time cloning my mother plant and i took it off her about a week into flowering and it is starting to pick up and grow. What light cycle should i put it under? 24 hours like a seedling and then just go right into vegataion again or should i put it right into 12 hours of light? This may soud like a noob question but like i said am new at this cloning thing.
anybody know?
Put it under for 16/8 or 18/6. In one of my books they proved that alight cyle of 16/8 allows the perfect balance to promote root growth. Anything more then that rootprduction dreases. I'll find you my post from somewhere else.
" Light Cycles
The dark cycle is very inportant to palnts. Respiration(this is when plants are making energy from sugar to oxygen) Continues in dark but at a much slower pace, almost independent of available oxygen because the leaves are not making oxygen in the dark.
In the dark there is a shift from leaf production to root production as the leaves transfer excess energy down to the branches and roots. Therefore, some dark time allows for better root structures. The "Experimental Root Growth 10 Days After Cutting" graph on page 33 shows that giving plants a 24-hour light cycle is not the way to supercharge growth"
This is from "How to supercharge your garden" With the graph on page 33 this follows...
"Light period for cuttings
PLants have a free running internal bio-rhythm of 21-27 hours. In this rhythm, they need dark time. Cuttings have a built in daily rhythm that they inherit from their parent. Cuttings will root better with a 6 hours to 8 hourdark period because this is the main time when leaves and the stems transfer energy down to the root zone for storage and growth."
The chart has hours of light per day on the bottom, and length of roots in millimeters.
-@ 4hours of light the roots after ten days were only 22mm long
-@ 8 hours of light after 10 days the roots were 25 mm long
-@12 hours of light we shoot up to 40mm long
-@16 hours it peaks at 50mm
-@20 hours it drops down to 37mm
-@ 24 hours it drops down to 29mm
There is also a shitload of info regauring root to yeild ratio vs veg to yeild ratio, and draws the conclusion that at the end of the experiements the root to yeild ratio was higher
Hell Yeah...kUDOS Chronic Chrissy. Yup that's right. This same thoery holds true when attempting to achieve a higher % of females from seed. the shorter the photoperiod the higher % of females...Consistantly
I love the 50% thrive at 16/8...since I use 16/8-17/9 for veg and clones
CC...I want to put your little post in the growfaqs. we need to clean up the typos in a couple places and put it in there...
aaahhh, gosh(blushing):p . Sure post it, fix anything you need to. I wish I could scan the graph in but I don't have the equipment for that.
do you have a link? where did the info originate?
From one of my books

It is written targeting marijuana, but there is no reference to it in the book so it is a pretty safe book. I picked it up from my grow shop.
