Quiz 1
The most common types of growbags, or slabs, are made up of either 100% rockwool, or 100% coconut coir.
T or F
True
A modern high tech greenhouse should be able to monitor and control which environmental parameters
Air, soil, and water temp, absolute and relative humidity, CO2 levels, water usage, nutrient and lighting levels
An advantage to having a removable benching systems is that…
it can reduce the time and labour needed when shipping out product
you can change the benching for each production cycle
it can make cleaning and sanitation easier at the end of the season
The primary goals of using some type of CEA technology in a production system are to
improve product quality, yield, and reduce production costs.
Which type of hydroponic system has the plants suspended in air, with the nutrient solution applied to the roots through a either an intermittent or constant mist?
Aeroponics
It is not possible to add any type of automation to a rolling bench system.
T or F
False
A hanging basket with a saucer will come with a plastic insert that sits inside the bottom of the pot, to create a space within the pot to act as a drainage water reservoir.
T or F
False
Which type of hydroponic system has the plants growing in a greenhouse soilless media with nutrient solutions typically applied through a drip irrigation system.
Hydroponic substrate culture
Stationary Benches will make better use of the space in a greenhouse production area than Rolling Benches.
T or F
False
When selecting an insert for your bedding plant production, an insert description of 806, would indicate that there are 6 tear apart cell packs, each with 8 cells.
T or F
False
Thermoformed plastic pots are heavier, higher quality plastic pots that are designed to be used for multiple growing seasons.
T or F
False
Thermoformed are single use and thin, plastic injected are strong and reusable
Which type of hydroponic system uses a thin layer of nutrient solution in a constant flow across the plant roots?
Nutrient Film Technique (NFT)
One of the main differences between a trough and a bench is that a trough will only hold one row of plants or containers, while a bench is wide enough to hold multiple.
T or F
True
A container production system can use either mineral based soils or soilless substrates to grow plants in.
T or F
True
When talking about cell size in a plug tray, growers are referring to the number of individual spaces in that are each designed to hold one seed or plant.
T or F
True
A Dutch Tray is a type of plant pot designed by a grower in the Netherlands.
T or F
False
A Dutch tray is actually a type of automated benching system.
A shuttle tray is a specially designed flat that will hold multiple pots.
T or F
True
Aquaponics is defined as the greenhouse production of plants that typically grow in outdoor ponds in their natural environment.
T or F
False
A standard size plug tray is approx 10.5” x 21” in size.
T or F
True
Troughs can be supported &/or configured in the greenhouse in which of the following ways?
tiered to provide multiple levels
On raised posts from the ground
Suspended by cables from the trusses or other overhead support
Which type of hydroponic system has plants suspended in a reservoir of nutrient solution with an aerator to add dissolved oxygen?
Raft or Deep Water Culture (DWC)
While bedding plants are the largest ornamental crop in terms of numbers of plants, Potted plant production is the largest ornamental crop by sales ($).
T or F
True
A hanging basket system is a good way to increase the use of the volume of space in a greenhouse, rather than just floor area.
T or F
True
Which type of hydroponic system uses a large volume of nutrient solution in a constant flow across the plant’s roots?
Deep Film Technique (DFT)
