Hi,I am lokesh from india,To a certain extent, this is true. Photosynthesis and metabolism are completely seperate processes going on at the same time. While photosynthesis�by definition�needs light to proceed, and therefore fluctuates greatly depending on the incident light strength, metabolism is roughly constant throughout the day. Since a lot of the plant's growth occurs during daylight hours, the rate of metabolism also fluctuates, because growth requires energy.

Hi, I am just setting up my 5'x7' pond and need some oxygenating plants plus other plants that will add to water quality. Might people in the New York area have Water Hyacinth, Pickeral, and oxygenating plants to give away? I live near the Brooklyn Botanical Gardens and will meet you in Brooklyn or Manhattan. Here is a list of some oxygenators: Parrot Feather Anacharis (Egeria densa) Bacopa (Bacopa caroliniana) Cabomba, Purple (Cabomba pulcherrima) Foxtail (Myriophyllum heterophyllum) Hornwort (Ceratophyllum demersum) Jungle Val (Vallisneria americana) Moneywort (Bacopa monnieri) Dwarf Sagittaria (Sagittaria subulata) Red Ludwegia Ranunculus aquatilis. water crowfoot Thank you

Yeah Mike, you're right - tomato cuttings root easily and don't need any artificial oxygenation if you put them in (a small or bigger) amount of water. If they die or wilt in a few days before taking roots, it's not because of a lack of oxygen in the water, but most likely because they suffer (ending up in cell damage) from heat or other unfavorable causes. The mostly overseen aspect of water oxygenation and condition is probably that Hydrogen Molecules have a high affinity for Oxygen molecules anyway -> H2O. Which is definitely a good thing as "water" tends to catch Oxygen molecules when ever it can. In fact it can't be without them and that's why you actually never encounter H in it's pure form in nature ;-) The other common error is to assume that one can saturate or hyper-charge water (or nutrient solution) with oxygen through mechanical methods. But as there is a limit to the dissolved oxygen water can absorb and hold, which is dependent on water (nutrient) temperature and to altitude to some extend - you can't exceed the physical maximum that can be dissolved under the existing conditions. At see level, water has indeed a bigger capacity of dissolved oxygen as water at a certain- or high altitude has. Hence, depending on temperatures and altitude (to some extend only for the later) water can (literally) only hold a certain amount of oxygen anyway. And here is exactly the point where ideal water temperatures of nutrients make sense. But then again (and here I truly speak from experience) sometimes over-idealized or even overrated. Although a temperature of 24 degree C is commonly accepted as ideal and is probably the best compromise between dissolved oxygen CAPACITY and growing rate, - a slightly higher temperature, up to 28 degree C, may end up in a better growing rates with CERTAIN conditions. As long as the (indeed lower) capacity of dissolved oxygen at higher nutrient temps is replaced continuously, of course. One must add here that the higher the nutrient temperatures climb, the more likely fungal introduction and spread becomes. There also is a lot of controversial debates and "experimentation" about if you can "add" any OXYGEN through air bubbles at all - and if, how much? And what would be the difference between finer and bigger bubbles? I've read a lot about the topic and couldn't conclude anything plausible out of it so far- which made me end up in not using any air bubblers at all. The only thing that I conclude, is that water movement of any sort (including the one created with bubblers) is accelerating and promoting oxygen replacement. Hence I generally use the downfall of any runback of nutrients for the purpose. With success I must say and apparently with sufficient re-oxygenation support. And that's the term I would use here, I guess: "re-oxygenation support" ;-) Cheers, Lucas

Go to my page and message me. I have lots of water hyacinth, tossed a wheelbarrow full this weekend. Have duck weed, and fairy moss also. What non pond plants do you have?
