Effect of early stop time and gift/radiation on EC behaviour
Light levels are now increasing rapidly as are the outside temperatures. The ventilators will be opened, subject to restriction with adequate P-band settings and outside weather influences to prevent cold air entering the glasshouse. Consequently, water uptake by the crop will increase but the weather can also fluctuate massively at this time of year, especially in Europe and Canada. However, maintaining a stable substrate EC is not difficult so long as correct settings are implemented.
