Green Mars Crack

@Cyrusdavirus, my first grow was this exactly, Green Crack under 2x Mars TSL2000's. Okay results, but way better lights out there. Mine went one month before both started having driver issues. I'm using them to finish a flower on a grow but they'll be gone after that. As it is I have to go in every day after timer comes on, and turn them off and on again to get the drivers to kick in, otherwise only one of the four quantum boards will actually be on. Yep they deliver an ok result, but nowhere near as good as more expensive lights, and the quality is essentially nil. You're starting with some of the lowest quality most inefficient diodes on the market for starters. Doesn't sound like you're getting the reliability issues I had, so maybe not an issue. But I can assure you if you're getting good frost with Mars you'd smash it with a quality light. Grow Lights Australia make the best lights on the market by any metric, if you're wondering ;) Of course when you get them for free makes it a bit easier! I don't think SF or Mars Hydro actually sell lights any more, they just give them away to growers on forums haha!
