A 300W LED can grow weed, but please do not waste your money on that light. That light uses far less than 300W.
Well 180 watts is enough led power to grow two plants. I can easily grow 4 autos under my solar storm 440. 320 actual watts. 80 watts per plant. However I'm not sure of the power of the mars lights. Some good, some bad reviews. Someone on this site tested a couple of these and they were actually even less than what the actual wattage of what they were. If you can afford it I'd say go with a more established light. I've seen journals proving it can grow but not sure of yield. But fuck it. Go for it. May just work fine for you.
No. Do not listen to this. It doesn't work for anyone....those that think it does work simply haven't used the lights that do "work." Will the plants grow? Yes-if it doesn't break first. Will the plants grow well? No. Plus the efficiency of the unit is less than an HPS, so he's almost better off with a toaster.
Not to start a debate mc but I've seen a few grows with this light that produced decent bud. I'm no proponent of the light. Never had one, never will buy one but if wants to try it out I say go ahead. $70. Not a big risk. And as far as "blurple" lights, I have the solar storm 440 and it has done well by me. And its par readings are pretty good as well. Check out growers house tests. You are right if you are saying "white" LEDs are better lights, with above average yield and much more efficient. I've never tried the light and apparently neither have you. All we can go on is what others have said about it. Again not trying to start a debate but you seemed to come off a little rude so I had to speak my mind. Good luck in your search op.
Not trying to be rude, just direct. There's no debate to be had on the panel suggested by OP. Best bet is to try to prevent all purchases and future heartbreak.
Wee imo imo you can't go wrong with hps unless you are facing some serious heat issues. They're inexpensive as well and will do the job properly. Apologies for clogging up your thread with information not requested.
