Well the ride has been good until now.
MarsHydro FC6500 is now broken.
After 2 months of use , all I can get out of it is 700 umol’s at 8 inches away.
There explanation.
The engineer said when the ambient temperature is too high, the power supply will automatically reduce the power to achieve the cooling effect.
So the power of the light and the intensity of the light will be reduced. Can you tell us what the current temperature inside the tent is?
It is recommended to reduce the temperature inside the tent through the fan.
I run at 78-79 , a bit too hot for MarsHydro stuff I guess.
I would NOT recommend one of these lights as once it’s broke you will be just that broke as you will need something else.
