almost no green light in this light, only blue, red light. What's the light, please?I just built a greenhouse this year, because of the lack of sunshine in Sichuan, I would like to add some light, please help recommend it, but if you can, please help me to introduce some professional knowledge.
The first floor of the "special light", it seems with very limited knowledge and scanty information. How do you know, there is no "little green, only blue and red light" grow light, there is a fake you negate!
It's called "plant growth lamp"". Simple, is T5 or T8 energy-saving lamp, get rid of (no) green powder, the price is cheap, less effective; good, with three colors of blue powder, add 680nm powder, the price is about 2 times the ordinary.
There are no so-called plant lights with blue and red lights.Usually in accordance with the different plants, choose red (peak wavelength 630nm) of plant growth lights, or choose the blue (peak wavelength 420nm) of plant growth lights.However, the market claims of plant growth lights, some are purely speculation concept.
