I breed in my spare time and my roses seedlings coming when the light in the spring is not yet sufficient. For this reason I use for many years the most diverse lighting. This lamp is the best thing I bought in recent years. She thinks the bright illumination spectrum (red and blue) from wonderful. The plants grow very healthy and my early splendidly drawn tomatoes grow to be without long shoots. The lamp hanging about 70 cm high with me and I reach the window with this lighting around 10,000 Lux at the focal point of the lamp. I have already recommended this lamp other breeding colleagues who are just as happy as I am.
