Humidity-the level of moisture in the air-can affect a plant's need for water. Plants use a process called transpiration to release water into the atmosphere through tiny openings in their leaves. High humidity slows this water loss.
Lack of humidity is a culprit in may indoor plant deaths, especially during the winter. The change in humidity from summer to winter is great enough, but if your houseplants vacationed outdoors for the summer, the transition is even greater.
Temperature and Humidity
Different plants have different recommended and growing temperatures. Always make sure that you check each plant's growing requirements--especially minimum and maximum temperature levels.
A: No, in fact, watering a plant to increase the humidity is a sure-fire way to kill it, especially during the winter months, when the humidity in most homes is extremely low.
Humidity
Plants typically need a high relative humidity to thrive, usually around 80 percent. This presents a problem since most households have a relative humidity around 20 to 50 percent.
humidity - While neither Phalaenopsis nor Paphiopedilum orchids need extremely high humidity, they do benefit from added humidity in winter. Placing pots on top of gravel in moisture-filled trays might help.

The humidity in your area. Peppers are sensitive to humidity. Jalapeño, cayenne, and mirasol all prefer arid climates, while habanero, Scotch bonnet, and datil prefer humid surroundings.
Humidity
Orchids thrive on high humidity. One method of maintaining high humidity is to place plants over another container filled with dampened sphagnum moss or pebbles.
Humidity is the friend to cattleyas. We can understand this from being in rain forests. Most cattleyas do well with being set on humidity trays. These are metal or plastic trays that are filled with pepples and then half full with water.
Humidity
In indoor gardening, humidity is a big issue. The amount of moisture in the air has effect on the growth of the plants. During mornings, you could spray the plants with water for their much-needed moisture.
humidity (adj. humid)The moisture in air.
humidorA tightly closed container which holds a constant level of moisture in the interior, such as for long-term preservation of seeds or storage of fruits and vegetables.
Humidity can be increased by placing plants on trays lined with pebbles and filled with water to within one half inch of the base of the pot. If you heat with wood, keep a pot of water on the stove.
A humidity range of 55-70% is ideal. You can attain this by growing the plants on a bed of damp sphagnum moss or on a pebble tray. Miltonias prefer the same room temperatures as we do. Daytime temperatures of 70 to 80 degrees F. are optimal.
A humidity hat is important if you don't have a humid igloo-type room. Two weeks is about all the hat needs to be on and the tape can be removed from 4 to 6 weeks according to whether it's warmed up or not.
The humidity dome pictured is actually a used plastic container that once held salad mix. I just flipped it over, making the lid my tray, and the container my dome. Good-sized take-away containers also work well.

RELATIVE HUMIDITY: The measurement of the amount of moisture in the atmosphere.
REMONTANT: Repeat bloomer. Plants that will bloom more than once a year.
Shading, humidity and ventilation
On warm, sunny days provide shade for plants, seedlings and cuttings. Increase the humidity by damping down the staging and floor.

Relative humidity The measurement of the amount of moisture in the atmosphere.
Reticulate Like a net, the interstices closed. Usually referring to the veins of a leaf.
Reniformis/reniforme Epithet meaning kidney shaped.
relative humidity The ratio of water vapor in the air to the amount of water vapor the air could hold at the current temperature and pressure.
To maintain humidity during germination, I place the flat in a plastic bag, cover it with plastic food wrap or use a plastic humidity cover. I don't seal the flat completely, as mold may form if air can't circulate.
Orchids need humidity and constant temperatures. If temperature and humidity are not easily controlled in your rooms, provide a three sided glass or Plexiglas enclosure for these incredible plants. Do some research.
To avoid low humidity problems, keep houseplants away from drying heat sources. As a result of low humidity, houseplants may show these symptoms:
Dropping of lower leaves, Yellow lower leaves, Brown leaf tips ...
Raise local humidity: Sometimes it isn't just warmer temperatures that the object of your affection requires; it's also higher humidity (in other words, tropical conditions).
The heat and humidity is relatively high during most of the year.
Watering is essential during Florida's dry season.
Plants should be chosen based on their zonal requirements.
Need very high humidity, medium or bright filtered light and well drained soil, slightly peaty soil. Keep the soil evenly moist except when dormant. Feed with balanced "acid fertilizer" every 2 weeks when actively growing.
To increase the humidity and stop the plant from losing too much moisture place a plastic bag over the pot, held off the plant with a few sticks (e.g. bamboo twigs) and secured around the pot with a rubber band.
Potted Seedling Humidity Helper
A good way to increase humidity around potted seedlings is to set a couple of seedling pots in a larger container of pebbles.
Pebble tray Grouping potted plants within a shallow, pebble filled tray in order to maintain humidity in an environment with central heating. Water is poured into the pebbles and evaporates up and around the plants.
Ficus trees require a lot of attention to be paid to watering and humidity. The trees do best when they are watered to the point where the soil feels moist to the touch. In addition, the trees should be misted twice daily.
This disease is most important in the eastern half of Oklahoma where rainfall and humidity levels are moderate to high. The bacteria survive on diseased plant debris and on tomato seed.

A pebble tray is used during the winter to counter the dry indoor air and increase the much needed humidity around your houseplants. It basically consists of flat container that is 2-6 inches deep.
The period of time between the beginning of an infection and the appearance of symptoms depends on how often and for how long temperature and humidity conditions allow fungal growth.
Another key aspect of a greenhouse is the ability to control the level of heat and humidity, keeping both at a level that will keep your plants happy. Too much heat, and your plants will wilt; too little and your plants will freeze.
Early morning watering is best due to: the lack of evaporation that takes place, low winds that can blow you lawn dry, high humidity and morning dew that adds to the moisture.
Maintaining proper levels of temperature and humidity are necessary for successful growth of the Boston fern. "BIG Boston Fern" states that Boston ferns like cool locations with lots of humidity.
It is possible that this is simply due to too much humidity but at the same time Rosemary can suffer from a virus which causes symptoms like these.
Because of lantana's tremendous tolerance of high heat and humidity, it makes an ideal replacement for pansies and other cool-season flowers that grow lanky and stop flowering in early summer.
So what can we do to provide this essential humidity ? Misting the tree is only beneficial for a short time, so what we recommend is to place the tree on a humidity tray and add water to the tray.
The summer months bring high humidity to many areas, creating perfect conditions for fungal problems such as the dreaded black spot.
