The impact of transplanting times, light exposure on hydroponic crop production

How quickly hydroponically-grown lettuce and leafy greens seedlings are transplanted and their exposure to LED light during propagation can impact crop production times. Most growers using traditional hydroponic substrates transplant lettuce and leafy greens seedlings as soon as the roots reach the bottom of the plugs. This usually takes from seven to 10 days. “We […]

Seedling plugs transplanted into a hydroponic system should be dominated by roots regardless of the substrate used.

Be aware of the challenges of using loose substrates in hydroponic production systems

If you’re going to use a loose substrate in a hydroponic production system, you may have to change how you handle starter plants and the treatment of recycled water. Many growers of ornamental plants including annuals and perennials traditionally use a peat-based substrate such as 70 percent peat, 30 percent perlite. The growers, who produce […]

Are you maintaining the proper oxygen levels in your hydroponic production system?

Growers have affordable options for ensuring plants receive sufficient oxygen in hydroponic production systems to maximize growth and to reduce the chances of disease.   Oxygen is critical in the development and growth of edible crops grown in hydroponic systems such as nutrient film technique (NFT) and deep water raft culture. Tyler Baras, special projects […]

Kellie Walters, a PhD graduate research assistant at Michigan State University, is conducting a hydroponics industry survey to see where she can make the biggest impact with her research.

Industry survey seeks information on hydroponic food production

Researchers at Michigan State and Iowa State Universities are looking for feedback from hydroponic food growers to help them determine where research is needed to benefit the industry. If you are doing hydroponic food production or thinking about doing this type of production, your input is needed. Controlled-environment agriculture (CEA) production researchers Roberto Lopez and […]

LEDs offer option for photoperiodic control

Research at Michigan State University shows growers have a choice when it comes to lights for photoperiodic control. As light bulb manufacturers phase out the production of incandescent bulbs, growers are looking for replacements to control flowering of ornamental plants. Researchers at Michigan State University have compared the efficiency and efficacy of LEDs for flowering […]

Monitoring is crucial for growing lettuce and leafy greens year round

Since lettuce and leafy greens have short production cycles, greenhouse growers need to stay focused if they want to be successful growing these crops year round. The increasing demand for locally-grown vegetables is causing more field vegetable growers, ornamental plant growers and new growers to look at trying to satisfy this market. Cornell University horticulture […]
