400w mercury vapour

Recommended Posts

Mercury Vapour lights are useless for growing plants. Regardless of how many watts they put out, they just don't have enough of the right spectrums. They use heaps of expensive power for little or no returns. If they were any good then experienced growers would be using them and not the expensive grow lights.


Types of HID used for growing:


Metal Halide - mostly for veg stage.


High Pressure Sodium – mostly for flowering stage.


Horticultural - HPS/MH veg and flower stages (Son-T-Agro, Son-T-Plus, Lucalox, Lucagrow, etc.).


My plants are grown from seedling/clone to harvest using 430w Son-T-Agro HPS/MH horticultural lights.
