Ah, cool. IS are good, I can only whole heartedly recommend the things I have used, or seen to bring good results. But 'buy cheap buy twice' usually. I'd just recommend goin with invisible sun, migro or vividled. No point buyin mars, may as well pay a bit extra for quality. You could get 2 x 100w IS boards for this cabinet, dimmable and they're full grow lights (start to finish) incase you ever wanna use em in flower too. Not much more I can add mate, hope you find something that suits ya needs.
