do I need another light

Will two 300w marshydro lights be enough for a 1.2x0.6x1.5m tent the lights are from eBay and use around 185 actual watt

How many plants you gonna grow in it? the coverage of Mars 300 are 2'x2'( growth), 1.5'x1.5'(bloom), your tent is 4'x2', so two Mars 300 should be OK.

Just the 4 plants maybe 7 if the lights can handle it

I think four will be OK, but 7 plants your tent will be crowded, and the two Mars 300 are not enough. In most case, I see our customer grow one plant with one Mars 300.
