Mars hydro 300 watt yield

Out of curiosity I made an array of 10- 15w cob spot lights.Next to a mars 300w the cobs grew twice as fast and twice as big ,for less money.

How much is a bit more

$185 total, free delivery in US, they were cheaper but prices went up recently.

They sell out as quick as they get restocked so best bet would be to pre order or contact @robincnn or @Stephenj37826 on here.

Been running 6 300 watt mars lights in a 4x4 tent on 24 hrs for over a year not 1 bulb burn out yet .

Mars 300 is a 135w light. So its not going to be crazy yields. If you can spend a bit more you can get 135w Quantum board which would be more efficient, more light and slim profile would suit a stealth situation

I ran the Mars 600 for 2 cycles before I upgraded to QBs. Now its in a 2x2 veg area and aggressively vented due to the heat it produces. My plants grew beautifully under that light I just did not get great yields but I can't fully blame the light.

Does this light mars 300 still work now? i hope to see 300's picture to compare my current growing, i used the mars hydro upgraded lamp. i searched here to find about marshydro official account, but it seems that they not be here.

Had OK results with this light
