摘要

The rectangular box shaped plant-pot is made of plastic or concrete, having a flat floor (18) with a drainage tilt to one of four side walls (10,12,14,16). Holes (20) in the low corner provide for drainage and aeration is by a row of vents (22) standing proud (24) of the floor. Pots may be stuck together back to back with the drain holes on the outside and the floor may be raised by wall downstands (28) forming a wedge shaped volume beneath. Notches (36) may allow air to circulate beneath, heating being supplied by hot water pipes (28) in a loop passing under the centre of two rows. Partition downstands may form sub-volumes with a vent, abutting external faces may include grooves (38) forming hot air ducts (40) and a head groove (42) on the longitudinal joint may locate a watering feed (44).
