This 3-ft. wide, 4 1/2-ft. tall low tunnel is ideal for protecting taller crops, such as cut flowers, peppers, and Brussels sprouts and other Brassicas. Cover with fabric row cover, insect netting, or plastic to allow for extra degrees of warmth when temperatures are cool, exclude insect pests, or protect cut flowers against water damage on the petals. Quickly create low tunnel hoops out of galvanized electrical conduit (EMT) to withstand fall winds and heavy winter snow loads. 1/2" conduit is recommended for most applications, and can be purchased at your local home improvement store or electrical supply house. 10' lengths are very economical. Also bends 3/4", or even 1" conduit, which can be used to provide extra strength for tunnel ends. Bender mounts to any solid surface, such as the corner of a shop workbench, a picnic table, or hay wagon. Finished tunnel measures 3' W x 4.5' H.
