This article presents the results of laboratory experiments on the spectrum, composition, and duration of light exposure in days for growing ornamental flower seedlings, using marigolds, the most common garden and park crop, as an example. The following spectrum, composition, and duration of light exposure in days are recommended for this crop, and laboratory experiments have confirmed them: red light for 12 days, red-blue light for 12 days, and blue light for 6 days. Marigold seedlings grown under this regime are stocky and have a high survival rate. It is also recommended to plant them in open ground at a lower density in shaded areas, and at a denser planting in open sunny locations, as these seedlings grown under our recommended regime are stress-resistant and have a more developed root system. We achieved these positive properties in our seedlings, in part, through the use of the complex mineral fertilizer "VitaMix" and the plant growth regulator "Zircon."
