strayner Posted February 6, 2010 Report Share Posted February 6, 2010 It's so cool! The leaves bend upwards towards the leaf axils as if they are folding in. Got me excited since i'm a botany fan so I thought i'd share Quote Link to comment Share on other sites More sharing options...
Wingin' It Posted February 6, 2010 Report Share Posted February 6, 2010 Hey! My Oxalis (non-aquatic) a.k.a. Lucky Clover plant does that too! And not just at night...when you touch it, it closes up! :shifty: Quote Link to comment Share on other sites More sharing options...

Fishful Thinking Posted February 6, 2010 Report Share Posted February 6, 2010 I find most of my plants go more vertical at night. Awesome how nature works, eh? Quote Link to comment Share on other sites More sharing options...

fishclubgirl Posted February 7, 2010 Report Share Posted February 7, 2010 Your plants do whatever you tell them to do. Werner says "send out a big flower spike" and your swords obey. Must be that thick german accent!! Quote Link to comment Share on other sites More sharing options...
strayner Posted February 7, 2010 Author Report Share Posted February 7, 2010 hahaha. I can see why H. polysperma is considered a weed in places - only a couple days and it's already completely bend towards the direction of the light.

jewels Posted February 8, 2010 Report Share Posted February 8, 2010 PHOTOTROPISM Below 320(?)Nm thats all light is good for ; no photosynthetic attributes I did not previously consider this had bearing on root direction as well - although makes prefect sense Some heavy reading HERE Slightly off topic but- This phenomenon can be used to your conceited advantage. If you want to over exaggerate the appearance of your planted tank ( for photographic purposes ) all you need is a very powerful light source. Your hood may work for this activity. The basic premise is simply to direct as much light as possible through the front of the aquarium ( perspective of intended photo ) Depending on the intensity of the source it may only take a few hours. The advantage here is that all the chloroplasts (leaf surface) will face the light. It gives a much fuller appearance to the 'scape when observing the leaf face as opposed to the leafs thickness. Incandescent light is not effective for this cheat; as it is mostly red. ♪ ♪ ♪ And thats why I call for the blue ♪ ♪ ♪ Quote Link to comment Share on other sites More sharing options...
