Night time temps for Paphs

[zdawgnight]

Hopefully this hasnt been asked a million times but i couldnt find it answered when i searched.

I have a couple paphs with mottle leaf and a couple with solid leaf, the way my room is setup the temps seem to favor my mottled type (staying around the high 60s at night) is there any suggestions to make its a happy place for both flowers? Is this possible?

I do have an extra fan that I could place on them if that is an option?

Id love to see my complex paphs flower for me, I am getting good growth but yet to see a spike show up.

Usually the leaf color I beleieve has to do with type of light they require.
Don't recall it being mentioned regarding temps.
What we need to know to help you is if they have tags what they are will tell us if they are intermediate /warm , intermediate /cool, or cool growers.

I have several paphs and my house is between 65 and 72 degrees during the winter. My paphs have been getting bright,indirect light and doing very well. I keep them moist and they do occasionally dry out between waterings but so far haven't heard any protests. The humidity has been staying at about 50%. I'm hoping I don't have to did the humidifier out until January Your paphs may not be old enough to bloom yet

I grow my Maudiae types intermediate, night time lows of about 15C (59F), if Maudiae type is what you mean by mottle leaf types (some Chinese paphs have mottled leaves too but they are cold growers).

What kind is the solid green leaved paph? There are different kinds of these too. Some grow warm and others cold.

the paphs I have are Paph delenatii (Pink doll x Pink elephant) this one has flowered for me last year and then a couple months ago. the one in question is Paph Oberhausen s Diament (primulinum x P. sanderianum). I also have Paph keyeshill (Carl Keyes x Winston Churchill) and Paph (Black Rook 'golden gate' x Maudie 'zebra'). These last 2 are pretty young so Im assuming thats why they are not blooming...

Of course since I posted on here asking about why my paph. Oberhausen's Diament has decided not to flower...the darn flower just spiked.... This forum must have magical powers

Most Paphs need a high humidity and medium brightness during their grownth.
Some Paphs need a higher brightness to make flower such as concolor, delenatii... . Others need some minerals. For example, Paph apple need a higher Ca+ to make flower..
You should research the properties of place where it or its father (mother) distribute about the soil. the temps, the brightness...
One tip for Paph Apple: Plus some little pieces of chalk when it's in the time making flower

I grow a wide variety of paphs in my greenhouse, and they are all exposed to roughly the same conditions - minimum of about 60°F, daytime whatever mother nature brings.

Your fan idea is a good one for general air movement, but will do nothing to affect temperature, as plants don't perspire like people do. Yes, constant air movement will dry a plant out faster than still air, but not at a rate sufficient for evaporative cooling.

Most Paphs are relatively tough adaptable plants, but too many of them don't do as well as they could because people rely on generalizations about mottled leaf vs, plain leaf, etc. Paphs live in very diverse climates and have several distinct cultural groups. You don't have any of the most extreme though.

The only one you listed that really prefers the 60F or cooler nights is the Keyeshill, the delenatii could stand that too but doesn't need it. A vigorously growing Maudiae type will accept 60F too, but is better at 65-70F and even 65F is a bit cool for the Oberhausen's Diament though. Aim for 65 for all if you can't provide different temps.

Keep the delenatii a bit dryer than the others, it can be prone to rot especially if it stays too wet in the winter.

The Maudiae cross needs the least light (put it in the shade behind the others), the others somehwhat brighter with Keyeshill brightest. If the OD is flowering for you it seems to be happy and the light should be OK for all of them, finding slightly brighter or more shaded spots within your growing space.

In an Ohio winter you can get cooler night temps closer to a window, but not so close to be cooler than 50F. In summers they should all be OK with normal day/night temps, maybe with A/C for the hottest days.

A fan is good for air movement, but shouldn't be aimed directly at the plants. It can dry them out too fast especially in winter dry air.

Thanks Paphmadman I really appreciate you breaking down my small group for me. I keep a variety of plants now and it all started because of an orchid... then those orchids doubled and now I have 4 paphs... Until this year I some how missed the memo that said there were so many species of paphs that existed (kind of embaracing). It a good thing forums like this exist or I would wandering lost.
