Did you read all the threads? This is like when i decided Devils Ivy would look great growing on the floor of a glass-house. It went rampant and was banished.

Seriously, Is there a room in the house that you could adapt as a plant room. This room has orchids, a fish tank (600 Litres) and the door is sealed so that warmth and humidity do not leak into the rest of the house during winter. I suppose the problem with a humidifier is containing the humidity.....it tends to even out in a large space.

Not currently, I MIGHT move in December

But will one steam humidifier on high work in a confinement?

My wife has asthma and needs the humidifier on at night in the winter. I'm not sure what the humidity level goes go. That being said you can get an indoor humidifier that will raise your levels indoors. Also vanilla needs to go to a minimum of 10' before it blooms and fruits.

Where do you live? Maybe I missed it, but your profile says 9a.

I wouldn't worry about it if you can put the plant outside over summer. You don't want that high humidity inside the house. You'll get mold.

Get it outdoors as soon as the weather permits.

The summers are 110 with 5% humidity...

Yeah but I wasn't growing it outside...

Like I said, check the locals...My guess is that there are few or none on this forum growing orchids in the desert. Inside or out. But check the locals!

If you're in the US, get this humidifier http://www.amazon.com/Vicks-Warm-Mist-Humidifier-Shut-Off/dp/B001FWXKTA/ref=sr_1_1?ie=UTF8&qid=1444781382&sr=8-1&keywords=vick%27s+warm+mist+humidifier

It use it all winter long and have humidity up to 90% some days. We have no mold in the house.

I got a small plastic green house to grow it in

So this greenhouse (OGrow Deluxe Walk in Greenhouse) gets a little hot, how do I keep it cooler in summer? Fan?

You need air circulation. You need to provide more information. This is like a guessing game.

If you want true help and advice, you need to tell us more about where you live and how why you are not growing outside.

Jane

I am growing it outside now, greenhouse, it is zone 9a, I know how to keep it warm though

Cuttings work on this plant? If so, I would take a couple and continue growing them as now. Use a different terrarium, if necessary. This will be your insurance.

No one has said it but growing a Vanilla (and getting it to flower)

in Las Vegas has a degree of difficulty like growing a Dracula in Miami.

With green-houses size does matter, larger sizes are better. Though those itty bitty ones can be useful.

Not that degree of difficulty matters in the orchid world, orchid obsessed guys and gals grow all sorts of strange things.

Added via edit. "growing orchids in a Desert" Deserts have a big plus and that is sunshine. There is a thriving Orchid Society in Las Vegas. It might be worth talking to some of the members of the Society and ask about their growing methods and growing enclosures.

Huh, I had an idea for a fan on cool in the summer and in winter a fan on warm

I am trying to help you!!!!! You have to copy the Climate where the Vanilla grows in nature.

There will never be a day in summer where the temperature is 110F and the humidity is about 10% in Vanilla home, so that is why SM suggested that you seek local orchid growing advice.

I think the Vanilla needs a 20 to 30C daily temperature range with say 50 to 60% humidity. So here that means a glass-house with heating in the winter and with a misting system in summer

The misting system will add humidity and cool the glass-house temps down.

That is what happens in the glass-house where I observed the Vanilla growing.

As for growing indoors you need local advice for that.

It will have a humidifier, the green house is 6 feet and 4 feet wide

The orchid society means your a member, errrr, how can I just visit?

You might want to look into a swamp cooler. Then you can cool and raise the humidity at the same time. Orchidnick made one and posted instructions A few years ago.

Can I see the blog please?

I would spend $4-5 online and get a humidity meter like this one not the most accurate but good enough to let you know if your in the ball park

Try this link. You can also do a search at the top of the page. Just type in swamp cooler, there were a few threads in the past on the topic

how to make a swamp cooler

You do not need to be a member to attend an Orchid Society meeting. I have done so many times as we moved five times in 3 years. I needed supplies which is far less expensive from the vendors at a meeting. I just show up and introduce myself to the lady/man at the desk. They let you in as a guest which are always welcome.

I have attended OS meetings all over and none require membership. Many people just come to hear a certain speaker or buy supplies.

I will almost guarantee you can attend a meeting without membership. Just Google your area Orchid Societies and find out when them meet. Usually once a month.

I bet you will meet so many people who are growing orchids (including vanilla) which are difficult for your climate and will give you advice. You can always ask for their phone #'s and call them after.

Usually great people who have a passion for growing orchids. Just show up, like I did so many times. You gain a wealth of info you just can't get on-line.

Jane

Thanks!

Done

Looks good! The only thing I would suggest would be to install a small fan to provide air movement. I've actually looked at that greenhouse when I lived in NY. I was going to use it to start vegetable and flower seedlings for my garden.

I have too many orchids to fit in it, but it would have worked great for seedlings. But you need air movement so a small fan would work.

Great job!

Jane

Thanks! A Vicks warm mist was installed, looks circular, and it is keeping it at 70 when its 50 thankfully, I will install a fan soon

Do not raise the humidity without air circulation. You will wind up with mold and sick plants. You need that fresh air coming in.

Jane

Will this work? I won't open it at night or cold days. Anyway, will it supply enough humidity? It's a little difficult to keep it open with how much humidity the Vicks has...
