You do if you're looking at the over all efficiency/performance/price points. If it is for a specific situation and it works by all means go nuts. If its anything bigger than a 3x3 that light might as well be off honestly.
Shoot run it at 500W still more efficient.
If he and his wife feel like dealing with that hassle, heat, and bill, light's light.
More efficient? Not at all. Ask anyone. The hallmark of LEDs lies specifically in their efficiency over HID.
Well, yeah. I said earlier, COBs are the way to go. I'm not talking about Mars, specifically because they kind of suck, though; I use ViparSpectra. They use Bridgelux 5w LEDs and a reflector.
Agreed. We're not really in opposition.All Im trying to say is that yes LEDs CAN be better however thats not always the case... as in with anything Mars makes.
Actual wattage is 450w?
No, ~206, to be fair.
I said that @Walterwhiter could reach his personal goal of 200g+ with a 400W light, that's it. If you thought I was talking to you, I wasn't. Mountain, meet molehill.
Some LEDs. Quite a few are lucky if they even match the efficiency of HPS. Either way, as long as you claim your 200W $149 light can replace 400W your "expertise" on the matter is hard to take seriously. And as long as a manufacturer claims that, they are lying, and I wouldn't trust anything else they say about their lights.
You know how I know you have never grown with an HPS?
He could also reach that with a 450w ViparSpectra.
Because I don't like to waste money and am specifically advising against it for his situation? We have two HIDs at my collective's place. We use the 250w for clones, early veg, and seed. We also keep a 400w we don't use.
I think you mean to be exact.
I dont think he can if its only a legit 2hundred watt light. Whats the footprint? Hps has penetration. Leds , not as much.
He definitely can. Look at my journal. They were flipped 3 weeks from seed. And LEDs definitely have penetration. Not even trying to start shit, you're cool. 3 weeks from seed, though, and about 3 ounces altogether. 4, if I had let the one finish out right. With only 3 weeks above ground before flowering, and I only topped one of the plants, I guarantee a 1.5-2 month normal veg will hit 200g.
No arguing just explain to me how a weaker light can penetrate deeper then a stronger light that can be placed closer to the canopy? If you know something I dont know id appreciate it if you explained it to me . If you're wrong id assume you'd like to know also.. worst case scenario someone learnes something. Its not starting shit its a win win situation. For both of us.
