temps for Aeranthes and Angraecum

flowellJune 5, 2011

I have the following Aeranthes




They were growing in my basement under lights with temps consistently in the 70F's.

All the info I find say they like hot -warm temps so I moved them outside. It is getting in the 90"s here and I am nervous this is too hot! I was wondering if anyone else is growing these and what temps thay are growing in.

I grow hot to warm plants but none of the specific ones you listed. They are heated to 60 degrees at night that is brought up to 70 in mid morning so that there is some temperature fluctuation. These are my lows.

I allow the temperature to rise in the greenhouse to 90 before cooling and bringing the humidity up to above 60%.

What is your humidity level? Orchids can take warmer temperatures if they are not too dry.

I grow Aeranthes Grandiose outside all summer. I don't know what zone you are in, so what I do might not be appropriate for your zone.

It is still indoors in a window until the nights warm up. Been cold (40's) at night so I'll wait. I will move it to a north-east exposure and leave it out until fall. It is spiking now. Doesn't seem to be bothered by the heat.

Hope this helps,

Hi Richard and Jane,
Thanks for the info. I think the humidity here in Indiana is on the low side normally. But lately has been above 50%. The temperatures are in the high 60's and low 70's at night but the day time temps have been up in the 90's. I moved these chids outside last weekend and they seem to be doing alright. I have a few Angraecum growing in the basement and they seem to be tolerant of 70F temps. However, they grow really slowly. I do not notice any undue stress yet but will keep an eye on them.
Thanks again

My Angs have been outside for 2 weeks and we've had night temps in the 40's. They are fine, I have them shaded but will move them into stronger light next week.

I would move your plants out of the basement and get them growing.
