Athosanswered grow question 5y ago 60*60 grow area or 4 sq ft. you need between 30 to 40 watts per sq ft to flower with led lights (you can go higher)
The V300 is 136 watts, that gives you 34 watts per sq ft, enough for flower. CON; it's burple
The P1000 is 100 watts, that gives you 25 watts per sq ft, enough to veg, but insufficient for flower. Great light for half your space
The P1500 is 150 watts, that would put you at 37 watts per sq ft. I would choose this one.
