Plants do uptake nutrients 24 hours a day. Not an expert on that issue but this is what experts say... If I am not wrong this topic has been already discussed in another Ukaps thread which I am not able to find.Plants dont take anything in when not photosynthesizing. Photosynthesis means Energy from light. Without light, no inward energy transfer can take place. At least, that's what I remember from school. (granted, that was a while ago haha)
Not True. The source of the confusion is that there is no Carbon fixing from external CO2 during the dark.Plants dont take anything in when not photosynthesizing.
Not True. Inward energy transfer is also known as "eating food".Without light, no inward energy transfer can take place
Correct.Plants do uptake nutrients 24 hours a day.
You can feed when you like, nutrient uptake occurs all the time. Chelated iron (FeEDTA) is an exception to this, not because of the plant, but because the Fe+++ ions are only released when the stable EDTA is degraded by light. It doesn't make any practical difference if you add it at night, or during the day, it will just remain as the chelate until "lights on".Would plants be able to use Fe/Traces at night, or are there special limitations on the nutrients used during the 'night' time with no lights. Also, would anyone imagine this would alter the growth pattern of the plant or could one expect normal growth from a plant.
As far as I know, the degradation of chelates is caused not only by light, but by temperature, pH, and probably by microbes also. So the chelates will degrade even at night to some degree.the Fe+++ ions are only released when the stable EDTA is degraded by light
I didn't know that, I know FeEDTA is less stable at low pH, but I didn't know that temperature also had an effect.As far as I know, the degradation of chelates is caused not only by light, but by temperature, pH, and probably by microbes also. So the chelates will degrade even at night to some degree..
