In order to thrive and grow, your weed needs… Light (brightness has a huge effect on yields) Air (fresh air with a slight breeze is best) a Grow Medium (place to grow, soil isn’t your only choice) the right Temperature (room temperature or a little warmer is perfect during the day...
When you decide on where to put your indoor garden, measure your space carefully. You’ll need to purchase, salvage, or build a platform that fits into that location. If you’re using a shared space – like the kitchen – consider if it will get in the way of other activities such as...
You need to know the OUTPUT capacity of the equipment at the reference outdoor temperature, which is straightforward for a furnace since performance doesn’t depend on outdoor temp. OTOH, determining output capacity for compressor-based equipment is more involved as it requires the manufacturer’s ...
in this case will be a small cardboard box. a 100-watt bulb in a reflector lamp will play the role of the sun. first, set up the box. make sure it has a lid that shuts tightly. put a thermometer inside to measure the temperature. then, arrange the light so that it shines ...
“The whole idea is to measure the temperature and relative humidity in the basement and on the street, on the basis of temperature and relative humidity to calculate the absolute humidity and make a decision on the inclusion of the exhaust fan in the basement. The theory for the calculation...
Wet bulb temperature (Twb) measures the amount of water that can be taken out of the air (by evaporation) - the old "sling psychrometer" used a simple mercury thermometer with a wet cloth over the sensing bulb to measure Twb by swinging the thermometer around at the end of a string - ...
It turns out they need a lot more information than they can get from an ordinary thermometer. Standard thermometers measure thedry bulbtemperature of the atmosphere; but the most important factor for snow conditions is thewet bulbtemperature. ...
In total, 95 precise and calibrated sensors were attached in the test chamber to measure average surface temperatures, dry-bulb air temperature, globe temperature, air velocity, and relative humidity. Determination of heat transfer coefficient between heated floor and space using the principles of ansi...
On a chilly -- but not cold -- day, that meant the furnace might come on for only a few minutes and then shut off again, having quickly raised the indoor temperature. Running a furnace that way is inefficient. It can be compared to starting a car to drive only a few blocks, then ...
For those who are familiar with indoor growing, we know that light is not the only essential element in an indoor garden. To get a healthy plant, the righttemperatureand humidity must prevail in the room. The main thing to know about these two is that they should be different when the ...
