Hi my fellow grasscity members. I will be doing my frist autogrow attempt i will have a 150 watt hps. I just need help with a grow tent !! What size well do ? Ill be growing 1-3 autogrows
A 150w HPS will cover an area of about 18"x18" (around 3 square foot). At a push maybe 24"x24" (4 square foot)
As long as the LED actually uses 150 watts then the yield will be quite comparable. The MarsHydro300 uses about that and will be cheaper to buy than a 150w HPS so I'd be inclined to buy the LED. If you're looking at an LED which has 150w in the title, then check how much it actually uses because it will probably use around 70 watts and won't be anywhere near as good as a 150w HPS
I have the MarsHydro300, it's a great light. Significantly more light than the cheap chinese cob arrays, even the ones that pull twice the power. I'd be cautious buying it from an unofficial source though - they are often knock offs. MarsHydro is good because they use quality (read: brand name) LEDs. I've seen several on eBay that were super cheap imitations. They put out so little light that you could literally point it at your eyes. I got mine from Amazon, but their website is good too. I'm thinking of going for their cree 256 pro series or perhaps 4 MarsHydro600s for flowering.
It's hard to tell, honestly. MarsHydro uses a sticker on a mass produced LED housing. It looks the same as mine (bought directly from MarsHydro), but I'm sure that sticker has to be easy to reproduce. It does look exactly the same though. I'm just distrustful of many eBay sellers.
That one states that it uses 135-140 watts. Mine uses 150 watts. There is a little variation. I think the newer ones use slightly fewer watts than the older ones
Buy them directly from @smokesara and you won't have to worry about fakes. They have the best customer service I have ever experienced
Hi Ani If you interested in the Mars 300, I can give you the email address of my colleague who is the sale rep of eBay, or you can pm me your email address and I will ask our colleague send email to you, so this can make sure that you buy the real mars hydro light.
