will 24hr light cycle hurt my bonsi mom?

[joe guy]

So here's the deal I'm going to take some more cuttings but lost my clone room so they will have to live with their moms for a bit and waswondering if I should just keep the 18-6 the moms are on and stick the babies in there too? will that screw my sucess rate up or should I just suck it up and build another clone room?

24 hour will be fine for your moms, as long as you don't go below a certain amount of light per day veg plants could care less.

Well thanx pure that is what I thought but didn't want to take the chance on screwing either of my mommas up love this strain.. I've learned so damn much from here I tend to get things mixed up every once and ahile.. figured id ask here.. two brains are better than one thanx again..

i got my bonsia moms too small after i took clones a couple cycles ago, and i take a new round of clones every month, so i needed mine to grow faster, i put them in a bigger pot and turned the lights up too 24 hours a day, works fine, obviously, back in the 90's everbody did it that way...sure it's a little pointless because 20 hours of light will give you the same growth as 24 in veg, but it's not going to hurt them, i am cloning and growing my moms under it for now untill my moms recover from their overly extreme trimming, then i go back to 20 hours of light 4 hours of dark, which i have found to maximize growth. with bonsai mom's you can slow down growth if needed by switching to 12 hours light 5.5 hours dark 1 hour light then 5.5 hours dark again, basically it's 12/12 but you interrupt the 12 hour dark period with an hour of light in the middle of it, this is enough to keep your plants from flowering but it slows growth so you need to keep bigger moms to ensure enough clones each round. my point is you can veg a plant in so many ways, the only "bad" way to veg a plant is one that causes the plant to start flowering!

Circadian rhythm

Some features of the human circadian biological clock
A circadian rhythm is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi and cyanobacteria. The term circadian comes from the Latin circa, meaning "around" (or "approximately"), and diem or dies, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology. Although circadian rhythms are endogenous ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers, commonly the most important of which is daylight.

[edit] History

The earliest known account of a circadian process dates from the 4th century BC, when Androsthenes, a ship captain serving under Alexander the Great, described diurnal leaf movements of the tamarind tree.[1]

The first recorded observation of an endogenous circadian oscillation was by the French scientist Jean-Jacques d'Ortous de Mairan in 1729. He noted that 24-hour patterns in the movement of the leaves of the plant Mimosa pudica continued even when the plants were kept in constant darkness, in the first experiment to attempt to distinguish an endogenous clock from responses to daily stimuli.[2][3]

In 1896, Patrick and Gilbert observed that during a prolonged period of sleep deprivation, sleepiness increases and decreases with a period of approximately 24 hours.[4] In 1918, J.S. Szymanski showed that animals are capable of maintaining 24-hour activity patterns in the absence of external cues such as light and changes in temperature.[5] Ron Konopka and Seymour Benzer isolated the first clock mutant in Drosophila in the early seventies and mapped the "period" gene, the first discovered genetic component of a circadian clock.[6] Joseph Takahashi discovered the first mammalian 'clock gene' (CLOCK) using mice in 1994.[7][8]

The term "circadian" was coined by Franz Halberg in the late 1950s.[9]

[edit] Criteria

To be called circadian, a biological rhythm must meet these four general criteria:
1.The rhythms repeat once a day (they have a 24-hour period). In order to keep track of the time of day, a clock must be at the same point at the same time each day, i.e. repeat every 24 hours.
2.The rhythms persist in the absence of external cues (endogenous). The rhythm persists in constant conditions with a period of about 24 hours. The rationale for this criterion is to distinguish circadian rhythms from simple responses to daily external cues. A rhythm cannot be said to be endogenous unless it has been tested in conditions without external periodic input.
3.The rhythms can be adjusted to match the local time (entrainable). The rhythm can be reset by exposure to external stimuli (such as light and heat), a process called entrainment. The rationale for this criterion is to distinguish circadian rhythms from other imaginable endogenous 24-hour rhythms that are immune to resetting by external cues, and hence do not serve the purpose of estimating the local time. Travel across time zones illustrates the ability of the human biological clock to adjust to the local time; a person will usually experience jet lag before entrainment of their circadian clock has brought it into sync with local time.
4.The rhythms maintain circadian periodicity over a range of physiological temperatures; they exhibit temperature compensation. Some organisms live at a broad range of temperatures, and differences in thermal energy will affect the kinetics of all molecular processes in their cell(s). In order to keep track of time, the organism's circadian clock must maintain a roughly 24-hour periodicity despite the changing kinetics, a property known as temperature compensation.
