ive heard mixed things about mars but its been quite a while- didnt even know they were still in business, but theres only 2 LED brands that i personally would purchase, when it comes to flowering anyway, and those are Platinum LED and KIND LED, yes they are pricey but they are actually engineered and designed for this purpose and thats why they preform well, the main reason you hear people talk shit about LED is because theres so many knock off cheapo brands out there that may look like the real deal but have none of the engineering put into them, When it comes to veg almost any LED can veg a plant, even cheapos, but you need a good quality, properly engineered light to get good results in flower.I have a mars 2 400 watt coming in on Wednesday what are your thought on that?
