Now first off i know these lights are cheap but gotta make with what you got now my question is will a 300 watt led mars hydro be decent in a 3x3 tent or should i add a second light in there? 4 plants in a 3 gallon pot maybe 5 gallons if they fit

Mars hydro 300 calls for no longer than 18 hours before giving it a rest. Anything over that is asking for heat failure on a driver. That's why you hear about people with half their light out. They most likely ran it for longer than recommended without a break for cool down

i ran mine on autos start to finish on 20/4 and my mars 300 still works perfect after 8 months of continuous 20/4 use.. BUT!! I keep my temps in a lower end range.. I personally like never going above 77 degrees
