2018-2019 Horticultural Catalog

Slitted Row Covers
• For improved vegetable production with
larger, earlier yields
• Maximum light penetration for highest
possible temperatures
• Use for peppers, tomatoes, eggplant,
cucumbers, melons, and many more
• Pre-cut slits vent excess heat while still
retaining heat with ventilation
Slitted Row Covers are made from clear polyethylene with
approximately 95% transparency. Pre-cut crosswise slits, provide
a method of ventilating hot air in periods of extreme heat. At night
the slits remain closed, reducing the rate of convective heat loss
and help to maintain warmer temperatures inside the tunnel. Preslitted
rowcovers usually provide from 2º-4ºF frost protection, but
more importantly they elevate daytime temperatures which provides
overall growth enhancement.
Slitted rowcovers have been used commercially for a number of
years with outstanding results. Growers who have employed slitted
rowcovers have been able to move up their planting and first harvest
dates by approximately two weeks.
It is recommended to use black plastic mulch and drip tape in
conjunction with slitted rowcovers. This will increase productivity
and earliness, while suppressing weed growth.
