Fertilizer usage can be much lower than with soilgrowing. Under hot conditions the better water availability to roots can reduce water stress on plants, giving better yields and longer plant life. For crops vulnerable to soil diseases, crippling losses can be substantially reduced or eliminated. Some crops, such as lettuce and strawberries, can be lifted from ground level to a much better height for planting, cultivation and harvesting. This gives much better working conditions and hence lower labour costs.
Some systems require less work in setting up and planting than growing in soil.
Weeds can be substantially reduced or eliminated. This is where planning should start. If any small business is to prosper, it must be able to sell its produce and at a reasonable price. You need to decide in detail exactly where you intend to market your crop. Consider your competition and how you will handle it.
