August 2011 - Add Temperature Sensors In Your Gable Area

When designing or constructing your greenhouse, add a temperature sensor in your gable area. Monitoring the temperatures in your gable area will help identify any issues with equipment located in that area. Expensive equipment such as gear motors or lights may be damaged with excessive temperature, so Identifying these temperatures will allow you to remedy any potential problems.

May 2011 - Calculating Light Energy Costs

Here is a simple formula for calculating the energy costs of your lights.

Information to gather:

STEP

EXAMPLE

1. Get your energy costs in kW/hr from your utility bill. (KW)

$0.12

2. Fixture Qty (FQ)

30

3. Bulb Wattage (BW) Use 1 for 1000W, 0.6 for 600w and 0.4 for 400w

0.6

4. Hour lights run per day (HR)

16


FORMULA

BW x KW x HR x FQ  = Cost to run fixtures per day
0.6 x $0.12 x 16 x 30 = $34.56 / Day
Multiply by the number of days in a month to get the monthly rate

March 2011 - When should you replace your bulb?

To get the best performance from your bulb, replace the bulb at its “economic” life and not when the bulb burns out. The economic life is generally defined as 60% of the “Rated life” of the bulb. This is stated in hours of operation.
