Equipment - foggers and fridge

[springee]

Hi
I was jus reading through some of the posts in this section and have some comments.
The fridge idea is jus BRILLIANT........for me that might well be the solution to me being able to start thinkin about growin some highlanders........Double thumbs up.
Now a question about an ultrasonic fogger.Wat is it?Wat role does ultrasound play in providing humidity?

Peace

OK...i'm answering my own question ...i jus did some searches on ultrasound foggers......my next question would be are they good for Neps?Wat are your experiences with using these foggers?

Thanks
Peace

Hi
So i have another question......i am assuming that the fridge is used for the plants to get a lower temperature at night,right?
Why do you have a light source in there unless u are givin the plants more light at night.

Peace

PS sorry for my insatiable curiosity ....that's how i got my trunk....

Me again, in case Matti is absent for while.
Ultrasonic foggers convert water into a superfine fog thus enhancing the humidity and making leafs wet. Without it a fridge can get pretty dry.
Matti is probably leaving his plants in the fridge, so he needs to illuminate them during day time with those lights. There are also people who move the plants daily to the fridge, but there are contradicting reports that this transport might cause stress on the plants. It surely causes stress on the humans ;D

mmm like volker has said.
the plants will stay in there perminantly over summer and maybe next winter.
as far as the foggers go........they are great! i think it is something to do with the sound waves but they grow massive! i had it in my lowland tank and my bical went from producing a new leaf evrey month or two too 2 weeks!.
Highlanders require alot of humidity so the fogger is essential,they basically work by vibrating a little disk at ultrasonic speed that sturs the water up and turns it into fog
TEST YOUR FRIDGE (WITH THERMIMITER) BEFORE YOU PUT PLANTS IN THERE as i found out once you drill a hole in them they can stay on all night with out timers and get down to -10c so ppl plzzz use timers and test ,test,test.
ohhhh if you dont have a fridge and or cant afford one go the mini greenhouse or terra with one of these babies www.eng.uwaterloo.ca/~gmilburn/ac/

yes a fridge will dry things out quickly and yes it is also for cooling at night
i suggest you dont buy any large species like rajah go for small scrambling species like aristolochioides,glabrata and tenticulata
during the day you should not take your plants out because they do not like the hot temps of 30+c during day time so they will stay cool in the fridge keep in mind the light dose heat up the fridge so you will have to have a day time cool of too about mid dayish for about 2hrs should drop the temp from 30c to about 10c.
all the best luck any more q's feel free to ask.

I belive i am the only one in australia to make one heres a rathur fuzzy picture but it will give you idears

as you can see theres the ultrasonic fogger sitting under the light (stainless steel round thing) sitting in a clear glass bowl invisible to the camera
on the top left you can see the black leeds going through s drilled hole.......simply cut of the electrical plugs.......stick the wires through re-wire the plugs on.......silicon the hole (i used a whole tube DOnt be afraid to use it all! ) and wallah.

Nice matti. Pretty big fridge you got there. I just realized the fridge I am planning to convert is about 1 fourth the size of yours. Don't you think the ultrasonic fogger will run out rather quickly?

no,i have it on for about half an houre evrey two hours

Matti,

Thanks for sharing the pic. Inspired by your modified fridge, I am now in the process of building my own ultra-highland grow chamber, using a second-hand fridge smaller than yours. Perhaps it is only sufficient for several S-sized nepenthes or one L-sized aristolochioides, depends on how much space I can save.





As I live in the lowland-intermediate part of Indonesia with plenty of sun, my idea is to let some diffused sunlight get inside the fridge through the sealed double-glass (see photo) with an inch of space between each glass and put the fridge outdoors under the diffused sunlight as follows:



Id say it works for temperature, as I gets roughly 10-13 Celcius at night and about 20-24 C at daytime inside the fridge. The problem is that the humidity (RH) inside the fridge is too low, about 10 to 20 % (humidity outside the fridge is at least 60%).

Now what to do next? I'm thinking of using a small container of water inside the fridge and circulate the water by using an aquarium circulator, make some kind of waterfall / water curtain and blow the water with a small fan attached to the back wall of the fridge to increase the humidity and also to avoid stagnant air. The problem is that the available space is limited, I would like to sace as much room as possible. But how do I increase the humidity without taking so much space?

I am thinking of using an ultrasonic fogger, but considering the limited space, I cannot put the fogger inside the fridge, but how do I separate the fogger from the fridge and still get the fog running well into the fridge?

For example I can make a small hole on the back wall of the fridge and run a small hose from there to the fogger but would that be effective? and how do I draw the water fog from an outside fogger into the fridge interior? Perhaps by using a typical aquarium circulator (pump), but will this create further problem, such as maybe the fog will be coverted into water once it gets chilled? If it happens then this method is useless because the air humidity will still be low.

Blowing air from a small (PC) fan installed inside the fridge towards running water (water curtain) inside the fridge, will this help increasing the humidity while dynamic flow of air?

Anyone has any experience running water fog into a fridge?

As you can see its a one-room fridge so the freezer is there too. Should this be a problem? I'm thinking of changing the freezer position so the cooling element will stick to the back wall of the fridge to save some more place.

What do you think? Should I use the water-curtain-with fan method (spacey) or the one using an ultrasonic fogger running from outside fridge? Any comment would be appreciated, thanks.
