cacti only open their stomata at night

besides why would you want to run hot electrical equipment 24 hours a day

24/0 is bad on a MJ plant n e ways, you wont get any flowers untill you put it on 12/12 or atelast quite a few hours of darkness if you dont want to even it out like nature

24 hours of light isn't bad for an MJ plant. It just makes it veg and not flower. You dont cut donw the lights to 12/12 until YOU want the plant to flower :wink:  But you can keep it at 18/6 cycle and still stay in ve. But no 24 hours light is not a problem, unless of course you are flowering. :wink:

plants can not handle 24 a day...well they can its just a waste. they start to lose their efficiency in capturing light around 18 hours and they use darkness to use the sugars made during the photo period. 24 hours is $$$$ for electrical. and its good to give your equipment a while to cool down.

well i guess i should have specified.. what i do is.. on sunny days.. i place them outside and allow them to soak up the natural sunlight and heat..

however then on rainy days.. and nights.. i usually place them under my supplement light..

so right now the light cycle is like 18 hours light/ 6 hours of darkness.. i think that should be good couple a couple of months then i will cut to a 14/10

Pot plants can handle 24/0, but I wouldn't do it. At night, there is the Calvin cycle and plants that requires darkness. Plus as others have said, waste of energy, but here's more basic science on it:

This process is also called carbon fixation, because the carbon from carbon dioxide is fixed in the carbohydrate sugar, releasing the oxygen into the air. The process, called the Calvin-Benson cycle consists of two parts: light and dark

Sunlight strikes the chloroplast cells of plant leaves, which contain pigments called chlorophyll. These absorb blue and red spectrums of light and reflect green back. The light excites electrons to a higher state (see carbon compound topic tab above) making a pyrophosphate bond in an ADP (adenine dinucleotide phosphate) molecule.

This is known as the "light cycle." The reactions and process involves oxidations and reductions. ADP is first oxidized by having the light excite its electrons. The oxygen is released from water, leaving a hydrogen ion and reduced NADPH (nicotinamide adenine dinucleotide phosphate) as follows:

NADP+ + H2O --> HADPH + H+ + O

A second "light cycle" reaction occurs where ADP is turned into ATP (adenosine triphosphate).

Later, in the "dark cycle" the NADPH and ATP reduce CO2 to form glucose (sugar) and water.

In summary:

* The light reaction
12 H2O + LIGHT --> 6O2 + 25 H+ +24e-
* The dark reaction
6 CO2 + 24H+ + 24e- --> C6 H12O6 + 6H2O



Glucose is the fundamental block. The plant makes lipids, amino acids, nucleic acids and starches from glucose, as needed.

This is the first half of the "carbon cycle." The second leg is the consumption of the plant materials and conversion of glucose to water and carbon dioxides by animals. A human being exhales 1.6 quarts of carbon dioxide per minute. That's 238 gallons an hour or 5,712 gallons of CO2 a day.

if you are worried about pedros mine have been under 24hrs of intense light all winter and they grew faster then they did in the summer

you want to put it on 12/12 for flowering not 14/10
