My first set of grow lights I bought was Mars LED grow lights .
I thought I was buying 300 watt lights .
They were NOT. they were 135 watts instead. The advertisement was somewhat miss leading ..
IMO i feel i was ripped off
Of all the regrets I have of buying any grow equipment the Mars lighting is at the top of the list.
Mars lights might be ok now but the lights I got was crap. I spent 1000.00 on lights that do not produce tight hard nuggets ..
Because I felt i was mislead on those grow lights I refuse to ever buy another mars product for the rest of my life.
I started to buy and assemble my own lighting using HLG, LED quantum boards.
And now I am giving the mars lights away , But notice most the lights are not working right .. seems half the LED board in burnt out ...
The Mars lights I got are good for VEG but not flowering.
My cost to assemble a DIY grow light I am buying from HLG components ass in the quantum boards and the heat sinks.
The power supplier I buy from who ever has the best price on Meamwells brand of power supplier.
Cost is about 0.60 cents per watt ..
In one of my 4x8 grow tent i have mixed brand of LED lights grow lights.
Mars, about 50cents per actual watt,
LED Supply DIY assemble Cree/Cob boards with a Makers programmable controller.. very expensive at about 3,50 pew watt.
DIY HLG price per watt is 0.60 per watt
All the plants grow toward the HLG lights ..
I have all the components to go with HLG lighting in all 3 grow tents/rooms. The mars are the first to go ,, and the Cree/Cob Lights are going too.
Second pic is the Cree/Cob light I assembled .
3rd is a HLG light, 4th is a CRee/COB and a HLG
Last is a mix of mars ,cree/cob, and HLG .
