mars hydro 300 watt led

Pulled 23 oz trimmed & cured. with both 700's. First timer with led+ hydro. Expect yields to increase next run.

Please help me mate! Many ppl told me to buy Mars and others not to (they say pay 800 usd to get a good led or stay with hps because mars is sh**), you seem to do great with the Mars and I would appreciate your opinion. I am going for the 700w mars. And I am not going for hydro now (maybe in the future), so do you have experience with your mars and dirt? Hope you can reply soon I really want to buy it now. Already been using hps and its expensive and fragile (but great results), do you think it is worth the change?

thanks for your time and I will love anyones answers if they can help me make a great choice. Good day or nght to everyone !

my 300 wt led looks like its the equivlent of my 150 hps havet used it yet though

I have a 300watt mars hydro and a generic 300watt led hydro galaxy i got from ebay in a 3x3x5,space and i just flipped to flower a few days ago and they seem to be doin well cant wait to see harvest results actual watts im unsure but im assuming 180watts each which would be around 360 actual power draw

Thanks for the replies, yeah it seems that mars is pretty good, all around I saw that but in one tread that I asked many ppl said that they are really bad, no one gave a good argument so I kept asking and it seems that I am going to buy the 700w or the 900w for 1 meter x 1 meter x 1.6 meter.

This is my first led i grew up on hps but the spectrum on the led looks cool cant wait to see it in action

Just popped a giga bud and a purple train wreck so im going to put it to work

The bulb? Never broke one ever

Anyone removed the glass on these units?

Removing the glass only gains more heat.. Heres my 3x3x5 high priority from 710 genetics on left and g13 labs blue og on right mars hydro on the right and hydro galaxy on left

I also plan to use the 300w marshydro but for a 1.5 x 4 grow cabinet, the lighting may not be ideal alone but I think I'm going to supplement it with about 8x 23w equivalent cfl bulbs for flowering. Those pull 1600 lumens each so I feel like if I hang those on the sides closer to plants and the led in the center out should perform fairly well until my first grow maybe 2 are done, after that I can upgrade my led

I have 4 I used to run in an area 40x46. Pulled glass and they all measured ~180w each. I pulled 12zips off 6 5 gal buckets of SourD. I now run cobs. I would give you a couple. I also have a blurple cob 200 w I'm not using.

Nice, I can't afford anything but the 1 led for now , besides the cfls because I can buy those from my work deducted from future paycheck

I guess I need to move some used led lamps.

Are you selling them discounted or moving them how exactly? Lol

That and cfls are a good combo. Plenty of light for that grow space

Thank you for the info, I had figured as much but it's good to hear from someone with more experience than myself.

I used the 2 700's and added a couple $50 cheapo Chinese red leds shortly after flip. Vegged for almost 7 weeks after transplant from 10 day old seedlings. I had 5 FP plants 2 Incredible bud plants (both high yield plants I will not be doing again) and one auto Mango something or other. This was a trial run. My first with either hydro or led. https://www.rollitup.org/t/started-my-first-grow-room-come-along-for-the-ride.857393/ Will be back on the horse as soon as my Divorce is final in a couple months. Expanding my grow room to 4*7 to 20*7 then I will be rocking the buds. My goal is 1g+ per real watt perpetual hydro. Lofty goal but I think Its doable so stay tuned in 3-5 months when I get the new grow going. I'll post a real growth thread.

how do you figure this man, the heat generated by the drivers and leds remains the same with or without the glass, with the glass on all heat goes out the side vents via the fans, without the glass, some of the heat goes out the side and some goes down and then out and up ( as heat rises),, BUT if you remove the glass you get MORE par , I chose to remove the glass from mine,, but then again this was before I tossed it in the DUMPSTER and built cob led light panels

thanks for the reply...

Abiqua is going the right direction in thought. Think "spectrum", its the reall reason l.e.d's are so cool. No more modified street lamps hovering in heavy contraptions above your meds.

Actually, I preach photon delivery and raw amounts, that is efficiency in a nutshull, how much and how well does a light source deliver it....Spectrum alone is a dead horse....THE HPS is considered a terrible "spectrum" in consideration to a source like the sun, but it has been the standard for 25+ years because it delivers monster yields....
The diodes I use [Cree CXA and Bridgelux Vero] emit about twice the amount of useable light watt per watt as ANY Mars fixture and costs about the same or less to build the fixture....until recently, these diodes weren't available and are barely in any commercial LED fixtures...and as people educate themselves and rely on the knowledge base here, they start to realize this potential...
@Tim Fox was one

That's why I cringe with these threads sometimes....the Mars users who are killing it, could be slaying it with Good tech.....I went from poor/medium tech averaging 350ppfd roughly and still managed .7 gram/watt across all my strains...Doubling my PPFD has not only increased my yields [still in early stages, but been pushing 1.1-.2 grams/watt across all strains, but it has also changed my plant characteristics in general too...ie. fatter stem growth is much more noticed, stretch, etc etc.

Spectrum can indeed be tuned but I have never noticed the effect of switching from say 2700k to 4000k in flower compared to doubling your PPFD. Raw power seems to be the grail...I worry about delivering it as efficiently as possible and smile when I notice it is tipping north of what the best HID lights are doing, watt per watt.
