[IBC] humidity
Good morning Group,
I have listened to you talk about humidity and the "No effect " it has on the Bonsai plant. Humidity play a significant roll in the nutriution of a plant. The part of the respiration and transpiration of a plant. A constant relative humidity (such as water under the plant then inside) is important for the plant's nutritional makeup to reduce stress to the plant whether in the winter, spring, summer or fall. Below is a small section of the chapter in Plant Nutrition I'm writing. Respiration Carbohydrates made during photosynthesis are of value to the plant when they are converted to energy. This energy is used in the building of new tissues or in plant growth. Oxidation is the chemical process by which sugars and starches produced by photosynthesis are converted to energy. It is similar to burning wood or coal to produce heat. Controlled oxidation in a living cell is known as respiration. By now it should be clear that respiration is the reverse of photosynthesis (Table 1.2). Unlike photosynthesis, respiration occurs at night as well as during the day. Respiration occurs in all life forms and in all cells. The release of accumulated carbon dioxide and the uptake of oxygen occurs at the cell level. In plants, there is simple diffusion into the open spaces within the leaf and exchange through the stomatas. Table 1.2. Comparison of Photosynthesis and Respiration. Photosynthesis Respiration I . Produces food 1. Uses food for plant energy 2. Stores energy 2. Releases energy 3. Occurs in cells that contain chloroplasts 3. Occurs in all cells 4. Releases oxygen 4. Uses oxygen 5. Uses water 5. Produces water Transpiration Transpiration is the process by which a plant loses water primarily from leaf stomata. Transpiration is a necessary process that uses about 90 percent of the water that enters the plant through the roots. Transpiration is necessary for mineral transport from the soil to the plant parts, for cooling plant parts through evaporation, to move sugars and plant chemicals, and to maintain a turgor pressure. The amount of water lost from the plant depends on several environmental factors, such as temperature, humidity and wind or air movement. As temperatures or air movement increase, transpiration increases. As humidity decreases, transpiration increases. In the winter time The plant reduces both transpiration and respiration processes. The plant still needs the water intake from other sources; such as the relative humidity from a water dish in the winter time as the stomata (this reduces transpiration) will open to increase to take in water vapor for photosynthesis needs. hope this helps, Bill Daniels In Sunny California ************************************************** ****************************** ++++Sponsored, in part, by John Quinn++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

Good morning Group, I have listened to you talk about humidity and the "No effect " it has on the Bonsai plant. I don't think that is what was said. The 'myth' referred to is that misting and water trays increase the relative humidity indoors to a significant degree. Billy M. claimed that, 'A tray of water under the plant can't increase the humidity in the air enough to matter.' If memory serves, the average air in a domestic room, say a dining room, changes twice an hour - once in your sitting room. The idea of creating a microclimate around a plant can only work in a room where no-one lives. Where no-one ever walks about or opens a window or door. Just my scientifically unsupported opinion.

[IBC] humidity
For what is worth, raising humidity by misting would be extremely hard
inside a house in winter. The relative humidity inside the house drops to 25-30% at the peak of the winter. It would be really hard to raise that to a level that tropical plants like. Having said that I regularly mist my tropicals but I drench them so that most of the plant becomes wet. Basically a mini shower. The rel. humidity rises to about 45% in the vicinity. In a hours time it would be hard to figure out that they ever got drenched. I never noticed any ill-effects of my misting schedule. Plants I want to keep on the drier side I just skip those. BTW my plants are in the basement with lights so it is easy to just mist them heavily. -Pranab |

[IBC] humidity
I grow seedlings in my garage using a grow light and a Saranwrap tent over the trays. For humidification, I use a $35 cold air ultrasonic mister from Walmart that has a 2 gallon reservoir. A simple plastic dryer duct connects the mister to the tent. I put the mister on an interval timer (10 minutes on, 30 off) and add water to the reservoir every 2 or 3 days. My coast live oak acorns were planted on 1 January and now the seedlings are about 6 inches tall and enjoying the sunshine and fresh air on my front porch. When I get a larger place, I'll set up a greenhouse with one of those continuous misting systems that are supposed to work so well for propagating seedlings and cuttings.
