I'm curious about your temps. I know you have said you grow S/H. Do you keep them dryer in the winter or does it matter?

Hi Maureen,

Since I grow in S/H I do not dare let them get any drier in winter as I do in summer. I like my Phals with roots. If you let them go dry. The new root growth will get accustomed to that and when they get flooded they die. The species that I am growing the coldest are aphordite, equestris, philippinensis, and schilleriana. I do have a Phal Mini Mark in the same area and it does keep blasting spikes so that one will have to go to a warmer spot.

About my winter temps in that window I am looking at highs in the 40s and 50s and lows around 34 to 40. The spikes do grow slower than they would if they were warmer but that northern window has great light for them.

Hi wow sorry it took me so long, I keep a temp no lower then 55 f and usually the temp stays steady at 60 f if it gets colder then 55 f I put them under the bathroom sink with partial light with a fan heater set to run a good 66 f tempature, I was just wondering how the tempature fluctuation effected them.
They seem to be doing quiet well, thier flowers are very healthy looking and so is the plant its self.

Anymore advice would be unbelievably appreciated because of I continue to do well with these my husband will allow me to buy more (:

thank you,
Samantha

Thanks Ted,

I have both equestris and their hybrids and “supermarket” hybrids. My winter temps for them have ranged from about 55-65 each day.

I’ve had more trouble with the latter regarding root rot. The equestris types either went into hibernation or just kept on growing but I didn’t lose any of them

I have had all my phalaenopsis in S/H for a year now and I’m still trying to get a feel for things. I was curious how low I could go tempwise. I’d like to know they can tolerate a cooler temp range in the fall so I could leave them in the greenhouse a little longer.

Samantha,

I recently came across an article from the AOS Orchids Magazine that while it explains how Phals are grown commercially. There is some good information in there for a beginner. The title is "Growing the Best Phalaenopsis". It is a four part series that was run from January 2007 through April 2007 issues. See links.

Samantha thanks a lot for those four informative articles. Now I am getting greedy, do you have more similar articles about dendrobiums, cattleas etc.
Thanking you,
