_____1. You are in the process of designing a new greenhouse for your landscape business. You are planning on using it to grow bedding plants that you will install in your clients’ yards. You have decided to use expanded metal benches to grow your plants. They are 4’ wide and 16’ long. You want to have a 30” aisle between the benches and also between the wall and the outside bench running down the long way in the greenhouse but also have a 5’ wide center aisle to facilitate moving plants in and out of the greenhouse. The benches will be placed end-to-end down the length of the greenhouse so that the only aisles will be 4’ wide, on the end of the benches, between the bench and the end walls. The greenhouse is 104’ long and 44’ wide. How many benches will fit in the greenhouse with this configuration? (You may want to try to draw a picture to help figure this out.)

A. 25B. 30

C. 36D. 42

_____ 2. You are building a new greenhouse. The dimensions are 20 feet wide X 96 feet long. The airflow required is 8 cfm per square foot of greenhouse area.

Problem: Using the chart below, select the fan that meets the minimum capacity requirements.

Capacity=8 cfm X area of greenhouse

Fan / Diameter / Rpm / Capacity (cfm) / Motor (hp)
A / 30” / 650 / 8,570 / 1/8

A. 26%C. 291%

B. 100%D. 391%

_____5. The proper pH of growing media is very important in assuring the availability of essential nutrients. Two pounds of finely ground limestone are needed to bring about a 1 pH unit change in 1 cubic yard of media. The following ingredients were used to mix the media necessary to pot 1000 geraniums:

22.5 cubic feet of sphagnum peat

10 cubic feet of washed sand

8 cubic feet of perlite

The pH of the above mixture was found to be 4.3. The optimum pH for the geranium crop is 5.8. 1 cubic yard = 27 cubic feet.

How many pounds of ground limestone should be added to the potting mixture to bring the pH to 5.8?

A. 2 pounds B. 3.5 pounds

C. 4.5 poundsD. 5.8 pounds

____6. You have a 24’ X 120’ polyethylene covered greenhouse. If you have determined that it would take a 32’ wide sheet of polyethylene to cover the greenhouse, what would be the total cost of TUFFLIFETM INFRAREDTM polyethylene needed to cover the house including 6% tax and no shipping charge.

A. $377.00 B. $251.00 . C. $399.62 D. $266.06

____7. A customer wants an assortment of plants to place in a flowerbed along the West side of the house which, because of trees, is partially shaded allowing for allowing for medium to low lighting condition. Which of the following combinations would you recommend?

A. Primrose, Gloxinia, TulipC. Caladium, Hydrangea, Heather

B. Calceolaria, Carnation, StaticeD. Mums, Dianthus, Wax Begonia
