I'm 20 yrs old medical student from Finland. I'll hope you understand my bad English. I have collected orchids for 4-5 years now. 90% my plants are in intermediate vivarium. It measures 140 x 60 x 120 (height) cm. Air temperature is regulated with thermostat, which pulls warm air in when needed. There's a hole in the wall and cold air (Finland) comes in and makes the temperature ideal. There's several systems maintaining humidity/watering: firstly aquarium, secondly ultra-sonic fogger in aquarium, thirdly water runs down the wall, fourthly (adjustable) misting system. All plants are mounted except soil-orchids and some soil-plants. Lighting is pretty heavy (12 dulux L 58 W lights and moonlight system (just decoration)), of course, this is only to make a daylight rhythm, all lights are on only for 3 hours. The backwall is made of flevopol (soil, coconut fiber, glue). Two 12 inch computer fans run the air around.
The setup has been on for 4 months, I have used several different systems (mainly mounted or not mounted) with kind a bad succes In many plants almost all roots are rot. I have had especially problems with phals. Dens seem to grow better, though they have been all the time mounted.
The newest setup is all plants mounted. The backwall takes little water in, (about halv a day moist). Pretty much like a coconut/fern panel. I water plants once a day with lightly fertilized water. I looked little old vivarium topics and wondered if someone could help me to get my system work better.
Catts small sized, different kinds about 20
dens, miniatures and small ones 25
brassavola nodosa 2
oncidium alliance 5
epidendrum ballerinas 3
Welcome Jussi! Your English is just fine. We are glad to have you join us. It sounds like you have a wonderful set up with your plants. We hope you will post some pictures of it for all of us to enjoy!
Wow, nice list, and your vivarium sounds impressive!!! Why do you keep your lights one for only 3 hours? And those sound like big computer fans.
I would love to see pictures if it is possible for you,
How do you think the Catts are doing for you? I have two in my little orchidarium, and one is about to bloom.
You have a great assortment of plants. What type of Paphs do you have?
You're set up sounds like it should work, but obviously if you are getting root rot, then it sounds like the medium is not aerating. Even with your fans on all the time, it might not be enough to 'dry' out the medium. The wet and dry cycle is especially important for Cattleyas and Brassavola.
What type of plants didn't like the set-up and got root rot?
OMG that vivarium is my dream!!!!!!!!!
Wow, nice Vivarium! Welcome!
I had problems with several genus. My Phals give me most problems (small nature species no hybrids). I grew them in baskets and they didn't like it at all. I think it was partly not enough dry and partly too dry. I had some help from couple vivarists and decided to grow my plants mounted, to get rid of the overwatering problem. I have had since no results (only a week), but it seems better... All plants develope new roots... I water now 15 minutes once a day and misting every 40 minutes 8 seconds. I post a lot more photos when I have time to take some.
PS I ment I have all the lights on 3 hours, half 6 hours and sixth 3 hours. One catt is blooming right now... cattleyotonia Why not. Only 4 blooms, I will post a pic soon...
Don't worry about your English, it's much better then most 20 year olds over here (myself included even though I'm 28). I have been looking at vivariums online for the past few weeks and yours is one of, if not THE nicest one I have seen. Nice work.
Thank's for all the compliments, but it truly isn't . If you want to make a good looking vivarium most orchids are not for you. They are too, way too large (most) or don't look good without flowers. Here is a list I personally like in vivarium:
- Mini phlas
- small angraecum
- some bulbos
-mini catts (real mini ones)
- Mini dens
- mini Paphs (Look the best, really heard though)
Some small dens
Of course there's others, but those are my favorites. If you want to make it work there should be atleast 50% other plants. Best are
small bromelia hybrids
tillandsias my absolute favorites
carnivore plants (small ones)
some swamp plants
Those look good all year round.
But it's not only about the good looks. For me it's mainly about the satisfaction (not much yet ). When you see a plant flowering which has been in your care since it was a seedling, it's the thing. Of course it would look better, with more color / more bromelias and tillandsias, but they are too easy...
But back too the problem... Before I get them flower, how can I roots for them. Basic questions: Is it possible to overwater plants mounted to fern root (no moss)? So is it bad if it is continiously wet? how much I should fertilize? With what kind of fertilizer? How many foot candles / lumens is good for catt? den? Phal? I mean precisely. What would be ideal temperature for dens and catts in winter: day? night? Ideal humidity?
