Are the PAR VALUES adequate to plant stages?
Keep in mind that when buying a grow light unit, what you actually pay for is light, not power. You may already know that a plant requires a lot of blue light in the beginning and a lot of Red light later on once it enters the flowering stage. So does this particular grow light produce sufficient light? And does it do it effectively? The answers to these questions determine whether a particular led grow light is a good purchase. So let us look into the Yehsence 1500w.
The led grow light from Yehsence have 3 different light options. Veg, Bloom
VEG option: For vegging, it draws 140 actual power and produces light waves between 430-660 nm. The blue light spectrum ranges from 420-500 nm, as you can see on the graph.
Bloom option: for bloom it draws 125 actual power and produces wave lenghts between 430-740nm. This is bad in our opinion. Plants need more intense red light in this stage.
Verdict: Is it worth the money??
This fixture is actually very decent as it has an integrated switch that allows you to adjust light according to plant stage. The unit could have been more efficient if it produced more concentrated blue light for VEG option and more intense red light for bloom option, nonetheless the light fixture delivers sufficient light to cover full plant growth. We believe that there are more efficient LED light fixtures out there but not for the price of $148.
