The research programme focuses on hydroponic production systems, organic production systems and water use efficiency of commercial vegetables. Sowing Time Although spinach can be sowed throughout the year as long as the climate is right, in South Africa there are two main sowing times that are used. Swiss chard have larger and harder leaves with large white veins while the real spinach have softer and smaller leaves with green soft veins. Further more you are placing a small seedling that will mature in 2-3 weeks. Planting density of various vegetable crops in…, Formulating a hydroponic nutrient solution –…, What type of crops are suitable for hydroponics, How to adjust the pH in hydroponic nutrient solutions, What is the difference between LDPE and HDPE…, Lettuce deficiency and toxicity symptoms of macro…. These systems have a 1m wide bed with a divider in between resulting in two channels of approximately 0.5m each. Compared to a young crop, these will have a different market segment and price obtained will be lower. Place the harvested product in a cool place.
