Soil-borne diseases are not an issue in substrate-grown crops. The plants are either grown in pots or bags on a rack system or planted in substrate slabs. Fertigation and irrigation are controlled by a fertilisation computer.
With labour costs constantly on the rise, a rack system is something that is worth considering. Picking rates of more than 20 kg/hour are not unusual.
Very vigorous plants such as tray, waiting bed or A+ plants are ideal for substrate cultivation and deliver maximum yields per metre in a short space of time. Two harvests per year are easy to achieve. You can see an example of a crop cycle of perpetual or remontant strawberry varieties here.
The following varieties are suitable for use in substrate culture:
