Process and means of plant cultivation in tiered arrangement

摘要

Plants grown on horizontal tiered benches in an environmentally controlled housing are constrained so that in their stems and also any side branches extend generally horizontally. The plants may be grown in tiers of canals 6 supplied with nutrient solution and are held horizontal by ties 4 attached to transverse supports 5. Alternatively plants may be grown in mats in the canals the mats being displaced lengthwise of the canals to bend the plants under supports 5.
