Reddit reviews MarsHydro Led Growing Lamps 600W Updated Led Grow Lights Full Spectrum for Indoor Plants Veg and Flower ETL Certificate Grow lamp for Hydroponics Greenhouse

I think that the Mars 600 everyone was talking about was Mars I 600, whereas that product line seems discontinued officially, so that leaves Mars II options only.

see: Mars 600 amazon

Those 6 LEDs you are using aren't strong enough for what you're using them for :( Adding 6 more weak lights is only throwing good money after bad, sadly. If I were you I would try to sell the ones you have already and get fewer, but more powerful LEDs such as [this one] (https://www.amazon.com/MarsHydro-Mars600-Spectrum-Certificate-Hydroponic/dp/B00XC3LBIW/ref=sr_1_7?ie=UTF8&qid=1485985374&sr=8-7&keywords=600W+led). That 600w LED is supposed to cover a 2.5x2.5 foot area during veg, less for bloom so the number you need will depend on how many plants you have in there.

I'd suggest going with a different light setup but otherwise the other stuff looks good.

The light you picked will create a lot of heat and use a lot of power. The LED is lower power, lower temperature, and will give you more PAR (Photosynthetically Active Radiation) for the money.

two of these https://www.amazon.com/MarsHydro-Mars600-Spectrum-Certificate-Hydroponic/dp/B00XC3LBIW

Are you including the Mars Reflector 96 or the Mars I "600W" in that? I've got them but they didn't seem to make it into the frame for either of these two pictures. Thanks for the feedback either way!

Indeed you can keep auto flowering plants small, but you can actually do that with any plant. Look up sea of green or screen of green methods to run small plants effectively. But can't stress this enough, I don't recommend autos, and if you're beginning with clones it's doubtful anyone has auto clones. Autos by nature are tough to clone, as the clones almost immediately begin to flower and don't have time to grow out as they would if they had been from seeds.

The tent method is great for beginners, but will run a bit more than $100. In total you would need a tent, LED light, inline fan, pots, soil, nutes, bamboo stalks, garden twine, PH testing kit, carbon filter, hanging clips, trimmers, drying rack, mason jars, and 62% boveda packs. If you search craigslist you can probably find a bunch of people selling their used gear. With a 2 x 4 tent you could yield 8 ounces or more, although it's more likely that you'll harvest 3-4 ounces your first go. A 4 x 4 tent would allow you lots of room and twice the yield.

Also in regards to LED's, be mindful of how many square feet you're trying to cover. I've got a few different LED's in my gardens, as well as MH/HPS lights. Many of the LED's claim to be full spectrum, and while that may be true, they vary quite a bit in terms of what they mean by that. I've got ones that are blueish white, blue, purple, more red, and one that has a switch from veg to flower. Out of all of them I really like my Mars Hydro , although I will say it does run very blue. Despite the dominantly blue spectrum, it's produced buds comparable to a 600w HPS, but with significantly more frost.

I was thinking 4ft would be too big inside as well, so cloning definitely seems like the way to go. I was thinking of using this light since it seems to have good reviews and isn't super expensive.

Thanks for the suggestion. It looks like the mars 600 is a little cheaper than 2 mars 300s. Any reason I should buy one over the other?

Which one of these would work for the tent in my OP and 4 plants? Or would I need an HPS?

Thanks for the info, I'm not sure on the version, https://www.amazon.com/MarsHydro-Mars600-Spectrum-Certificate-Hydroponic/dp/B00XC3LBIW/ref=sr_1_1?ie=UTF8&qid=1486758106&sr=8-1&keywords=mars+hydro+600w
whatever that one is?

I thought aiming for around 50 watts per sq ft was best to aim for. Have you any idea how much difference there could be to the plants in the two different spaces (~71W per sq ft in the 2x2 to ~31W in the 3x3)?

Thanks! Im going to get some today.
The light im using is a Marshydro 600W LED (275W true output). I got it for $140 from the Marshydro store on ebay!

I really like the light because I feel it has good penetration, it does not produce a lot of heat, and it is easy of my electric bill haha. I have not experienced a single problem with it!

its a marketing ploy really, they say its to increase the longevity of the light boards themselves but who knows. https://www.amazon.com/MarsHydro-Updated-Spectrum-Certificate-Hydroponic/dp/B00XC3LBIW

if this is the same light or similar then you can read on the page that it actually only pulls 132 watts +- 10%

" ENERGY-SAVING: Consuming only 132watt±10% with the same effect of typical 150W hps or HID grow lights. "

its a common mistake you shouldn't really worry about it, just know that most people recommend anywhere from 30-50 watts of actual true wattage per sqft of tent, and in your case you only have about just a little over 15.

Again only saying mars hydro 600w gives it a bit of leniency but the best 600w blurple led ive seen maxes out at like 180 watts which could work but you would probably see a massive improvement if you added some more light in there.

If your light isnt a blurple then i could be totally off.

DIY are superior, as you can get the exact nm frequencies you like, but if you aren't handy with electronics you can run the risk of fire or simply blowing money on a dud product. You can get 600w leds for 150 now on amazon, and they work really well.

Good luck, and keep the sub updated!

I helped set up a grow with an LED light. The light itself was about $150-$200 but it's perfect for veg and flowering. I would recommend going that route since it helps with the heat and electricity.

This is the light. 600w equivalent only using 300w. It's full spectrum and the light is actually a really intense violet color, its pretty badass. The person growing says their electricity has only gone up by about $30 (.12c/kWh or so)

MarsHydro Mars300 Mars600 Led Grpow Light(Mars600 with Veg/Bloom Spectrum for Hydroponic Indoor Greenhouse/Garden Plant Growing, 272W True Watt Panel) https://www.amazon.com/dp/B00XC3LBIW/ref=cm_sw_r_cp_apa_KvovxbYQTRKNV

Sorry for the link formatting, on mobile. I highly recommend the light though. It has had plenty of power for the three plants that they have in about the same footage as your grow.

when I upgrade should I go for a 300w or the 600w?
