"91-е годы "рвачества"

Temperature Requirements
1. Most plants prefer human comfort range: 70-75 degrees F daytime temperatures
   and 60-65 degrees F nighttime temperatures.
2. An absolute minimum temperature of 50 degrees F must be observed. Plant
   damage will result below this figure. Rapid temperature fluctuations of 30-40
   degrees F can also be detrimental to plants.
3. "Q-10" phenomenon of respiration: for every 10 degrees C rise in temperature,
   plants' respiration rate and food consumption doubles.
4. Both photosynthesis and respiration decline and stop with time, as
   temperatures go beyond 80 degrees F. Beware of the greenhouse effect!
Water Supply Requirements
1. Movable and railing planters are often watered by watering can. Provide
   convenient access to hot and cold potable water by hose bibbs and/or service
   sinks (preferably in janitor's closet) during normal working hours, with long
   (min. 24 in.) faucet-to-sink or floor distances. Provide for maximum of 200
   ft travel on all floors.
2. At-grade floor planters are usually watered by hose extension wand. Provide
   hose bibbs above soil line (for maximum travel of 50 ft) with capped "tee"
   stub-outs beneath soil line. If soil temperature is apt to get abnormally low
   in winter, provide hot and cold water by mixer-faucet type hose bibbs.
3. High concentrations of fluoride and chlorine in water supply can cause damage
   to plants. Provide water with low concentrations of these elements and with a
   pH value of 5.0-6.0. Higher or lower pH levels can result in higher plant
   maintenance costs.
Hvac Effect On Plants
1. Air conditioning (cooled air) generally is not detrimental to plants, even if
   it is "directed" at plants. The ventilation here is what counts! Good
   ventilation is a must with plants; otherwise oxygen and temperatures build
   up. Heat supply, on the other hand, when "directed" at plants, can truly be
   disastrous. Plan for supplies directed away from plants, but maintain
   adequate ventilation.
2. Extended heat or power failures of sufficient duration can damage plant
   health. The lower limit of temperature as a steady state is 65 degrees F for
   plant survival. Brief drops to 55 degrees F (less than 1 hr) are the lower
   limit before damage. Temperatures up to 85 degrees F for only 2 days a week
   can usually be tolerated.
3. The relative humidity should not be allowed to fall below 30%, as plants
   prefer a relative humidity of 50-60%.
Uplighting and Electrical Needs
1. May be of some benefit to plants, but inefficient for plant photosynthesis
   because of plant physiological structure. Chlorophyll is usually in upper
   part of leaf.
2. Uplighting should never be utilized as sole lighting source for plants.
3. Waterproof duplex outlets above soil line with a waterproof junction box
   below soil line are usually adequate for "atmosphere" uplighting and water
   fountain pumps.
Storage Requirements
Provide a secured storage space of approximately 30 sq ft for watering equipment
and other maintenance materials. It may be desirable to combine water supply and
janitor needs in the same storage area.
Air Pollution Effects On Plants
Problems result from inadequate ventilation. Excessive chlorine gas from
swimming pool areas can be a damaging problem, as well as excessive fumes from
toxic cleaning substances for floor finishes, etc. Ventilation a must here!
