Cucumber, cv. Super Dominus (Peto Seed, Parma, Italy) transplants were produced. Two seeds were planted in a plastic pot, 10×10 cm, containing a growing medium composed of 50% soil and 50% soft sand a sand ( a sand with a smaller than normal grain size). Pots were irrigated and transferred to a growth chamber temperature 25-30oC. Plants were exposed to 25 fluorescent lamps (40 w) model T10 (Pars Company, Mashhad, Iran) in parallel. The distance from lamps to pot surface was 50 cm. Plants were irrigated once for two days using 5 or 6 L water for 220 pots in each application. After 12 days one-true-leaf, hardened (plants transferred out of growth chamber with deficit irrigation and exposed to alternating sun and shade) transplants were transferred to the prepared field soil.
