Plant behaviour?

[bobtail]

I've noticed my Cabomba australis starts to close the upper fronds towards the end of the day and when I turn lights on in the morning they are open.
I've also noticed hat the pearling is greatest at the point where the Cabomba starts closing up.

Any thoughts?

Well yes I was wondering if you had been keeping up with TBR ? Tom posted a dandy on photoreceptors and their roles in plant physiology. RE: http://www.barrreport.com/barr-repo...r-phytochrome-photoreceptors-their-roles.html

Fascinating Stuff !

 

[Tom Barr]

That is called Nyctinasty ( a rythmic diurnal movement).
Many plants do it, not just aquatics.
Flowers etc.

All sorts of parts, leaves etc.

Hmm shame I have'nt access to that

I have some Osteospermums in the garden which have a rythym similar which seems to be linked with temperature and daylight.

Regarding the Cabomba I would have thought that because you are providing artificial light you would affect the natural pattern, yet it seems not to be, as though the plant is driven by a preset routine which is unnafectable( is that a word? )

 

[Professor Myers]

Indeed...W/ 9 years in college, and a library full of books on the subject much of the best information is just recently available. I mean to say you can't find this stuff in books. At the very least have the information spoon fed to you in a manner specifically regarding our aquatic plants and aquariums. The subscription cost is a pittance compared to the rest of the hobby.

There are lots of grand theories available on the internet and most of them are changing daily fortunately the membership here is pretty meat and potato logic without alot of ceremonious blathering.

As far as affecting environmental conditions we can really only do so much in contrast to genetic structure, and evolution. We only imagine ourselves to be in control. LOL. Grtz, Prof M

While Im not trying to avoid paying the subscription (I'm interested just not that much at the moment) I have noticed that the Cabomba Australis opens at 8 am and closes at 8 pm It would be interesting to know where they get their triggers from as they cannot see daylight and if its inbuilt then why do they open at 4 am australian time?

 

[Tom Barr]

The local UKAPS as well as many Plant groups have no membership dues.

This is because of a suggestion that really hit home.
Sell your plants to pay for the resources you need.

So if we need funds for our local club, we sell them on line.
We really never sell to each other(Exchanges/swaps only), but most fish clubs love to buy plants.......ebay etc.

So right there, 1 hour's worth of work saved, or some plant sales can easily pay for most issues you might have.

I call this plant dollars or plant pounds or plant Yen etc.

Works well.

Simple.

Good business.

Helps the clubs.

As far as timing, the plants can tell when to close, based on what they are adapted to.
They also can turn towards the sun at sunset then during the night, even before there is any light, they will turn and face the sun.

Im saying I aint paying $50 to find out

 

[Tom Barr]

I've seen folks spend 200$ and still don't know
I see folks routinely buy snake oils, try wonky water schemes, methods etc I know that do not work for more.

It's 12.95$, a tad less if you are in a plant club(both Greg and myself support and promote that)........... not 50$, who told you it was 50$?

and I ought to know..........

You do not get the same info here as you will in a written article.

Im not saying its too expensive per se or that its not worth every single penny ,I know it would be money well spent its just money I've not got at the moment.
After I have got my fundamentals for the tank set up I will be subscribing

 

[Professor Myers]

"After I have got my fundamentals for the tank set up I will be subscribing"

Why buy the cow when you can get the milk for free ?

Trust me I understand the general emotion. Sounds reasonable enough...Unfortunately There are manufacturers, and retailers that are counting on just that ! An Uneducated Consumer, is a Generous Consumer !!!

Filters that are half baked. Terrestrial plants that have no business what so ever in an aquarium. Fancy Beautiful VHO lights that are the wrong spectrum entirely or over powered, hot and loud. Simple chemicals with hyped up packaging at an 800% mark up etc... Sadly these charlatans may account for 50% of the retail product sold. Half the books on the shelves are misquoted or just plain plagiarized, regurgitated Pseudoscience Hogwash !!!

No Thanks ! 10% of nuthin is still NUTHIN !!!

Tom and Greg have saved me a small fortune and I barely get to compensate them as it is. I'll re-up for the Lifetime Membership soon enough... and won't even give it a second thought.

I've been in the Aquarium hobby for 40 years. I have a Masters in Marine Biology, and a Bachelors in Organic Chemistry. Yet I still learn something new every single day.

Like what side my bread is buttered on Fer Instance... Best Of Luck, Prof M

 

[bobtail]

I have kept fish and plants for quite a few years and have half a clue on the hows and whys. I discovered by accident that of you ignore the shop and dont use a UG filter your plants grow much better, along with not buying an air pump. I have my tank set up it has good growth, algae of 2 of 3 forms, snails and it doesnt look pretty but its there and it gives me a focus and the opportunity to try things out.
I found this site after Id started buying after checking out the subscription its a pittance for sure .
I need no convincing that I need to subscribe

to anyone reading who hasnt set up yet, Dont do it like me !! Subscribe first

 

[Tom Barr]

Well, you are involved in the local club as well.
I kicked that ball going as it .....was..... well....just that time. UKAPS can help you save a lot and achieve a lot of goals.

Cost: some time. Some plant sales drives
The goal here is similar. Some time = some plants grown out and sold.

But the services provided are very different and synergistic.
This is true for any other free forum, local club etc.

I am not trying to be like any other forum, we have plenty as it is.
This forum is all plant business and produces a newsletter every month that is unlike anything else. There are not any hobbyists that routinely respond in the hobby like myself. There are excellent Aquatic plant Biologist, but they rarely if ever post anything. So in that regards, I am unique, however it's not something I have pride for, rather regret, I wish there were more like me.

I wish folks could see and put this stuff together easier. I'm certainly not the best, but I try given the time constraints I have.

Still, there are not other folks that will do this, test this, write this, share this etc.

I'm not trying to sell you, I'm a lousy salesman, I am trying to help the hobby out as well as you.

If I save someone 100$ with my help(test kits alone for most folks save this with using EI), then some $ for good articles specifically on plants, mixing research and practical aspects is a pretty cheap and good deal.

I kill no trees in the process(maybe later for the book), it goes out at the same time all over the world, no mail issues, and folks want to read something more than the same old things and never understand why or look to the future about how and why things work in our tanks the way they do.

No one really answers these basic questions about planted tanks.
They give you some quick trite explanation, in some cases it might be right, but any good answer will lead to 3 or more questions. So if you get a good answer, you should have good questions all over the place.

Thus the hobby and our understanding of it evolves.
As that occurs, we also have more control and better management ability to achieve our horticultural goals.

Knowledge is far more powerful than heating cables

Tom Barr

 

[bobtail]

Ahh heating cables that was the first thing I read about and it was your response that steered me away from them .

I know there are many who have benefitted from your advice , I am humbled by not only the knowledge but the time you put into your responses.

I realise this is all off topic but hey his is my thread

I like the pass it on idea, I'm quite talented in a lot of areas but no expert, just once I may have found something to get expert about

 

[bobtail]

Well finally Ive got my paypal into credit and took the plunge.

WOW Im blown away by the knowledge in here.
Apologies if I came across like I wanted all for nothing

I respect and appreciate the time and knowledge availabe .

 

[Tom Barr]

Hi, no, not at all. You need not apologize, most feel or think the way you do, I think most do.

My goal is not to have religious follwers etc, rather to get folks to think and pose questions themselves.

So that also goes for rationalizing the expense here and the usefulness of the information.

I'm a cheap guy as much as anyone.
But there are trade offs and do I get something real and worthwhile for my $$$ if I buy a tank, filter, sediment, advice, articles etc?

I'd better or I'll never buy it again!
I do DIY as much as anyone if not more.
I also buy very nice equipment and modified it.

My gaol is to have precisely what I want, not someone else's set of trade off goals.

I liike ADA's aesthetic, but I dislike Lily pipes, lights, their cansiter filters, stands and a few other more minor things. Overall, though, I like that style.

So I can modify and change a few things, test a few things to see what's in them, r research to see if it's worth my/our time to use them.

Cost: benefit analysis basically.

That's sort of what EI is actually.

I test and use to tell folks they should test and use high quality test kits, I did this for 8-9 years before I started suggesting conservatively at first, EI.

Still, EI does not, nor can any method, meet every goal an aquarist might have.

That's both good and bad.
Good because we can do less work and still achieve the goals with other methods. Bad because some clowns think that one method to the Godsend for all planted aquariums.

You need to know several methods to achieve those larger goals to help folks.

I've never met anyone to date that really promotes both CO2 and non CO2 method on equal terms or that can do each method to high level, Nor marine plants.

But it's not about what I can do, it's much much more about how I can help other folks achieve these goals, see the trade offs, see what can be done to meet the set of goals they might have to fully enjoy the hobby and have long term success.

We can be clever and avoid a lot of extra cost and work if we keep an open mind. But not so much as one wise person once said " that our brains falls".

Tom Barr

 

[evandro.carrenho]

Tom,

You mentioned that you dislike lily pipes from ADA.

I was considering bying them for they are glass-made, what would unclutter the look of my tank.

Is there any problem with their function or you actually don't like their style.

Thanks,
Evandro.
