The growth of Capsicum annuum L., in self-built environments controllable growth chambers, at various day/night temperature, lighting intensity, light-dark cycle and hydroponic nutrient concentration were analyzed and compared with seedlings incubated in January, March and April of 2010 at a local incubation farm. Results indicated that seedlings grown under environmental controlled conditions can do transplantation directly without acclimatization. The seedlings grown under the conditions of day/night temperature 30/20 ℃, light-dark cycle 18/6hr, lighting intensity 395μmol m-2 s-1, and full strength Hoagland solution had the highest quality and required only 4 weeks of incubation time. However, the conditions of day/night temperature 30/20 ℃, light-dark cycle 18/6hr, lighting intensity 190μmol m-2 s-1, and half strength (or full strength) of Hoagland solution were more economical in terms of the electricity required. Under these conditions, the quality of incubated seedlings was as good as those best seedlings from the local incubation farm, also required 4 weeks of incubation time, but saved half the electricity than the best combination.
