I saw a few reviews saying your light with the bridgelux chips is a better light than their other model using Samsung chips, although I don't remember why now though. I also read Mars Hydro is famous for exaggerating their par readings a little, but regardless it is a powerful light.


I'd say no problem using it without CO2 also. I'm using a similar one, different brand, without co2. But it is bright and your plants will drink a lot of water, so mix your nutes a little weaker so things don't get burnt.

Good luck and welcome to RIU. Post some pics when you can!!

You don't NEED it but it will benefit you as I mentioned in this post: https://rollitup.org/t/seedlings.1093087/post-17399457
