Hi. This is my new orchidarium. I have some new begonia purchases in it for now.
I plan to use it mostly to hold begonias that need high humidity and for propagation of various other plants.
As it stands I can only get a humidity of 65% max.
I would like to know if I need a higher percentage for terrarium begonias?
Also. One of the plants it supposed to be Benitochiba. Does it look like it is?
Yes, that is Benitochiba. It often defoliates in winter so don't get alarmed and water it too much when it does this.
Humidity in a container is a double edged sword - initially plants grow like crazy and they can stay perfect without any more water for weeks. What you have to watch for is rot and leaf drop. Leaf drop can cause mold to take hold and then it in turn can spread to the healthy leaves. If you vent to remove the excess moisture and forget to close it back up the container can quickly dry out causing damage as well. It can be a vicious cycle but other folks have it figured out.
Here is a picture of one terrarium of a club member. She has hundreds of tanks, bowls, and humidity domes. Her basement is packed as well as her enclosed porch and a bedroom (hard to walk in there).
Thanks, Butch. I think that is exactly what happened to my soli-mutata. It was pretty and then just went to ugly with rotting leaves. It isn't dead but not sure how it will come out. I did spray it with Captan the other day.
So, 65% is about right?
Killdawabbit, I've had the Grand Cayman orchidarium for several years and with 2 bubble stones the humidity gets into the mid 70's. If I'm spraying my vandas it gets into the 80's for a short while. How many bubble stones did yours come with and can you add more to increase the humidity if needed?
Yea, it was expensive. I bought it for my mother when she was in the early stages of Alzheimer's. I found out soon she doesn't like anything.
I had it in the box for about six months and finally got around to setting it up last week.
So, 60-something percent is enough?
What is a good number? Depends on the plant. For tropical rain forest plants the higher the better (90%?) while according to the literature I am reading even succulents don't like it bone dry but do prefer lower humidity (30%). When I've been in some large commercial greenhouses and conservatories it is so humid in there that I feel like I need a change of clothes after a few minutes of just walking about and even worse - downright nauseous if it is hot too!
