Humidity!
Hello everyone!
What is the best percentage of humidity to grow Phal and Paph! I just bought an hygrometer and it shows 40% of relative humidity. Is this good? Thanks Claude P.S : Happy New year, Bonne Année |
Humidity!
40% isn't high enough.
Needs to be at least 60% with 70% to 80% being closer to the ideal figure. "Claude" wrote in message . .. Hello everyone! What is the best percentage of humidity to grow Phal and Paph!

Humidity!
Most culture sheets for Phals (or Paphs) that I have seen say something like "humidity of 50% or higher is ideal". However, Phals are known for being able to adapt to sub-ideal conditions (and even thrive in them), so I would think that 40% humidity is 'good enough' (or will anyone object to that?). One related thing that I have read is that good air movement becomes more important with higher humidity. Joanna "Claude" wrote in message . .. Hello everyone!

Sorry for unintentional double post, and I just noticed Boleros reply that
indead objects to my 'good enough' understanding. I would think that for those of us who are growing Phals on windowsills at home and not in greenhouses, achieving 70-80% humidity is not really an option.

Has anyone out there been living in a home in 70-80% humidity? Joanna Joanna & Claude, 40% is very good for most houses. Joanna is correct, Phals are 'house plant' material. They will love 'human' temperatures and can survive our humidity, with an extra watering now and again. If your growing on a windowsill, group the plants together and add foliage plants to the area. This will make the immediate area higher slightly, as well as look more decorative. If your growing under lights; can you restrict the air from leaving the area but use a fan to keep it circulating? You can then bubble up an aquarium airstone in a glass of water to pump a touch more humidity into the plant area. This also works if your using an old aquarium for an orchidarium.

I for one will disagree with that.
The very best results are achieved with humidity above 60%, there is no way you can achieve great results with 40%. The plants will survive and may well flower but not as well as they can.

I wasn't replying on behalf of people growing on a window sill.
I will replying on behalf on what the plant would prefer to have. The best growers I know maintain humidity in their green houses at 70% or more for Phals or Paphs.

40% will probably be at the lower end of the scale, the humidity ,will
obviously rise at night.I grow in a loft on a largish tray with clay pebbles for humidity,at the end of the day when the heating has been on humidity falls to around 40/45% rising upto around 60% sometimes higher.I spray every morning with a fine mist,which instantly raises the humidity & by the end of the day the plants have dried off for the night .This is obviously harder to do when you grow on a windowsill or similar.Humidity is hard to maintain were ever you grow,once you know how low & high humidity gets in your situation you tend to stop worrying about it & get on with your routine.

Thank you everyone!
I must say that I grow all my plant in S/H culture and I`m wondering if humidity is an issue with that method of culture. My pots are on wooden shelve with fluorescent light. During the day, the humidity goes aroud 40 to 45 % and at night goes up to 55 %. Should I be concerned? Should I put all my pots on trays with water knowing they are already in S/H culture???? Thanks Claude Happy New Year to all! Bonne et Heureuse Année à Tous! |

Sorry, but humidty trays do very little good in an open room.
Copying from my own page on humidty: "A general caveat about all of the humidity-enhancing methods described for in-home growing: remember that unless your growing area is sealed off from the rest of your home, any effort to raise the humidity level around your plants is actually trying to raise the humidity of your entire house! Because of that, especially if there is air circulation due to fans or forced air heating, the less active methods like the humidity trays appear to be of very limited value." Copying an Orchidsource.com post by Todd Zimmerman: "I am sorry, but "Hmidity trays add 10% to 20% humidity to your room humidity." is just not possible unless your room is an aquarium. I have been distressed about this bit of published folk lore ever since I began growing. Without going into the physics of it.... I have sat in a small, room with no ventilation, taking readings every five minutes (trials of ten readings) from a hygrometer suspended 10" above an open seedling tray of water (leaf height), and found no difference (statistically significant or even imaginarily noticable) when compared to readings taken above the same tray when it was dry. The hygrometer was tested between trials and the room allowed to vent fully. In addition to the vapor input to the room from the tray (surface areas about 1.5 square feet), my lungs (surface area coparable to that of a tennis court) were actively pumping warm air, at a humidity of 95%, into that same room. Even that did not increase the humidity readings more than 2% from the beginning of a trial to the end (equally for both wet and dry trays). Pots over the tray would reduce the effective evaporative surface area of the tray. Plants will increase humidity by transpiration and by slowing air movement. Fans will move water vapor away from the plants. Someone said that there was a similar study published in Orchids magazine several years ago (with the same conclusions)." -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .. . . . . . . . . . .

Humidity!
Again, didn't know I was dealing with people who couldn't grow outside and
that the question was targetted at only those people. It is still less than ideal...... Are you saying that those that own a greenhouse are more than mere mortals?

Humidity!
40% will probably be at the lower end of the scale, the humidity ,will
obviously rise at night.I grow in a loft on a largish tray with clay pebbles for humidity,at the end of the day when the heating has been on humidity falls to around 40/45% rising upto around 60% sometimes higher.I spray every morning with a fine mist,which instantly raises the humidity & by the end of the day the plants have dried off for the night .This is obviously harder to do when you grow on a windowsill or similar.Humidity is hard to maintain were ever you grow,once you know how low & high humidity gets in your situation you tend to stop worrying about it & get on with your routine.

Humidity!
Claude,
The same applies to S/H pots effect on humidity as it does for trays - they are adding some humidity, but you're in effect, humidifying the entire room and home or apartment. In other words, the effect is minimal. Minimal plus minimal is still minimal. I suppose that a phalaenopsis with its leaves spread out flat over the medium are seeing a localized boost in RH, but as little as a few inches above the medium and the effect pretty much vanishes. Two more comments: 1. How are your plants doing? If the answer is "well," then don't fret. If the answer isn't that positive, 2. Consider getting a console humidifier with sufficient capacity to raise the RH to somewhere in the 50% - 60% range. Not only will your plants like it, but you will, as well. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .. . . . . . . . . . . "Claude" wrote in message .. . Thank you everyone! I must say that I grow all my plant in S/H culture and I`m wondering if humidity is an issue with that method of culture. My pots are on wooden shelve with fluorescent light. During the day, the humidity goes aroud 40 to 45 % and at night goes up to 55 %. Should I be concerned? Should I put all my pots on trays with water knowing they are already in S/H culture???? Thanks Claude Happy New Year to all! Bonne et Heureuse Année à Tous! |
