Thank you.
Of course you have helped me. I googled up the light source to see that it's more efficient than my sources (136lm/W as opposed to 122lm/W). Actually, it's a very powerful source. I was surprised to find out that they are available in our country too.
My problem is that I usually grow over 10 plants at a time and grow chambers (is that what you call them officially?) can accommodate maximum 3 plants. But I will think about replacing the light sources.
