How are Vine crops supported when grown inside a greenhouse in hydroponic systems?

• By planting them directly in the ground

• By using roller Hooks and clips to attach them to a trellis

• By suspending them in the water all the time

• By using a recirculatory drip irrigation system

What is the recommended method for growing tomatoes and cucumbers in hydroponic systems?

• Suspending them in the water all the time

• Allowing the suckers to develop and Vine out

• Growing them as a central leader and treating them like a vine

• Using a lean and lower method for trellising

Why are Vine crops not typically grown in deep water culture in hydroponic systems?

• Because they require a higher pH for nutrient water

• Because they prefer to have a dry down period and need access to the Vines

• Because they need to be suspended in the water all the time

• Because they do not require any additional labor

• 2.4 to 2.6

• 4.0 to 4.2

• 3.0 to 3.2

What is the advantage of recirculatory systems in hydroponic Vine crop cultivation?

• They prevent any water from being collected and brought back to the reservoir

• They do not require any nutrient amendments

• They require less labor for maintenance

• They allow for a continuous supply of fresh water

How long does it typically take for tomatoes to reach fruition in hydroponic systems?

• 40-45 days
