This reeks of bullshit "viral" marketing. AKA spamvertising, not Tim's post, the one he quoted.

Yeah I was just trying to get the rep to offer a discount for thread watchers and throw some freebies wazzas and oilmaker68s way, seemed like a good idea after reading the entire thread and seeing the rep in the forum. It was 3am and I was super high so maybe not a great idea in retrospect. I've never posted to any forum ever so sorry if I broke some unwritten rule about asking for a discount, not sure why people took offence to that. I'm pretty sure if I was working for Mars hydro my English would be way more messed up, have you read there website, it's a pisser. Either way if wazza and oil maker ever see this thanks for the info guys, really informative. To anyone offended, chill out and go smoke a bowl, no offense intended but thanks for the heads up.

I tried one out but went back to using a HOT5 w one of 8 bulbs being a UVB with less power usage and asimilar results. I'm going to wait until this round is over and put the Mars Led in place of one of my three 1KW HPS / MH lights giving it more of a chance in a bigger area. Unlike where I tried it my main room where I veg & flower is walled top to bottom with 4 mil diamond stamped IR blocker / mylar and that makes a large difference. Even just the 8 bulb T5HO with a mix of four 6500K and four 2800K bulbs seems like it's insanely bright inside the "mylar box". With the ventilation off It seems like I could cook something in there with the HPS housings powered on! But I'm gonna give it more of a shot in the mylar box!!How many growers are using Mars Hydro led grow light and grow tent here?

I haven't looked deep into it figuring the Asian companies building them would be able to put them together at the most cost effective ratio. However, I repair laptops, desktops, TV's, PS3/PS4's, XBOX 360, ONE, tablets, cell phones, built my own custom 8 outlet 240 volt timer flip box with a 120 volt tripper plug, so I feel I am VERY capable of doing this and know by just making a few tweaks to Mars design flaws ( hydraulic bearing fans, different attachment setup making it way easier for people with any height tent or a permanent design, upward flowing heat dissipating louvers to make the heat expelled flow to the top of someone's grow tent / room where 99% of people have their exhaust. These were the few problems I ran into that I feel I could easily fix on a personal design.
You sound as if you speak from experience possibly? Have you built one? How hard was it getting your hands on the newer 5 point spectrum chips? I was told they have a pretty good grip on the overflow of these not wanting someone like us to come along and start building them out of a pole barn here in the USA for $75 less. Like I said, this is what I heard, the truth to any of it, I have not researched. But I am very, very curious now on looking into building a light. Taking the guts from a SUN BLAZE T5HO like mine which is just the four foot 8 bulb fluorescent and even cannibalizing the housing cutting the 8 tube shoots with a table saw / sled setup, then combining the 5 pc LED'S identical or similar to the sun series light (pictured) in between a T5HO 10,000K to 12,000K bulb in basic rows combining every spectrum of light possible all in one!
The very best medical grade cannabis I've ever grown lab tested out to 25.5% THC and those plants I used 8 small "facial tanner" bulbs rigged along the outside of two 1k MH/HPS lights in a 4ft sq x 2 enclosed area. This herb was not grown sea of green, but was very meticulously LST into circles clipping every other node trimming every 3 days taking me so many more hours than I care to admit but creating those awesome top bud only plants that we all strive for. No popcorn undergrowth energy wasted because it was all trimmed or trained away. Was it all the LST & trimming or that & the UV bulbs? Maybe it was just the spectrum of light from the UV bulbs. But it was the closest thing to outdoor diamond dust covered looking plants I've seen inside. So having the bulbs to switch out spectrums would be another amazing bonus. One of you guys would eventually figure out the best combination of what bulbs to create the super light.
If I could get my hands on even a broken donated Mars Sun light I would tear down my Sun Blaze T5 HO with no qualms and try to build the first one. All the Mars LED I tried out was missing was some supplemental light making it ok to leave at 36" and still be crazy bright like an HPS/MH light is. As most people, the only qualm I usually hear about LED's is how you have to keep them right on top the canopy and they don’t penetrate like sodium lamps. Well maybe adding the supplemental also energy efficient T5 HO's to the awesome 5 pc LED'S would be the ticket not to mention all the T5 HO bulbs to mix and match until one of us comes up with the perfect combo.
I grew outdoors for ten years before coming inside and know well how those outdoor plants that sparkle like they are drenched in diamond dust is basically impossible to re-create indoors without the uv light or its color of spectrum that maybe a 10,000 Kelvin or 12,000 Kelvin bulb closely mimics. I might hear why not just use both lights? Because taking both and creating one energy efficient grow lamp with all of the options we as growers want no matter it be in tents, rooms, closets, or attics is the end all goal. One energy efficient light that closely as possible re-creates the sun to grow perfect plants that doesn’t kill the power bill or need two 740 CFM blower fans just to operate is the goal for us all. I love my hps / mh lights, but if I could get something along the lines of what I'm talking about for an affordable price and was certain it6 would work and get the same if not better yields, I would switch in a second. But so far the only LED lights to even come close to be as good or better than hps / mh lights are so crazy priced normal everyday people like me can't afford them. So I'm just spit balling a solution.

My 300 watt panel just burned out after a year of nonstop use. not to shabby for 80 bucks I think I will upgrade to a new model I definitely want to use the new mars with cree guts. What is going to be prices on those?

This is my first grow.
Details as follows,
Tent-60cm x 120 x 150
Flood and drain buckets- 20L flooded for 4 minutes 4 times a day
Medium- clay balls
Strain- ak48 x 2 in tent week 5 in veg both 20cm high
Light- Mars hydro led 450 w 144x3 5 w 60 cm above plants. 18hrs on 6 off
Air flow- 1 hydroponics fan in tent 1 exhaust fan sucking air out.
Ph- 5.7-6.4, 80 percent of the time at 5.8-6.1
Temp- kept between 18c-26c
Res- 45L ec of between 1800 and 2000
Nutes- general hydro flora nova grow and calimag, mixed 1 ml per for Calimag and the rest made up of flora nova grow to reach desired ec of 1800-2000.
My problem is from week two I have had problems with the leaves start yellowing then this progresses to tip burn than the serated edges burn and basically the whole leaf burns away. Nothing I have done seems to stop the problem. It doesnt get any worse or better and the plants keep growing. At first I thought it was over watering so I dropped from 5 times a day for 15 mins down to 4 times to 3 times then to 4 times at 4 mins now I'm at 3 times at 4 mins. No change. Then I thought it was the LED was too close so I raised them from 18inch to 25 inch. No change. I change the nutes every two weeks and flush clay balls 2 or 3 times during that period to prevent build up. I read that LED need calimag so that why I have used that from the start. Can anyone pleaaaase help???
Thank you.

Dude post this question in the
General Marijuana Growing section
https://www.rollitup.org/f/general-marijuana-growing.39/
you will get far more help there than here in the mars section, sound def like nute burn, do you know your ppm
any how, get this question up over there there are super good growers who can help

I'm growing with a Mars hydro 450 watt reflector series so I thought it was the right place. My ppm is by memory 1100 but I measure in ec which is 1950.

Ya the Mars people only know how to put together low power chip lights, the real good growers with real good help for you are over in the other section

Hello All,
I'm a first time indoor grower and need some advice or reassurance. I've grown a few plants outside with decent luck but, I want to try my luck indoors. As you can see I'm running two 300 watt China built Mars Hydro LEDs I bought off Amazon and eBay, with a few CFLs. I'm pulling just over 500 watt with all the lights on. I feel I'm set up well with cool and ventilation. I plan to put the three small pants in the grow that I cloned off the larger female.
My question is;
Will the LEDs be okay for veg and flower or should I have spent more on better lights?
Do I need the CFLs?
How many plants can I grow in the 2'x4' tent?
Any advice will help!!

Just my humble opinion:
First- Nice setup, seems like you've created a decent little grow area and thought through a lot of the details. Props on the plants, as a RDWC under current system user myself, it's not simple to keep hydro plants thriving. So your doing very well in my opinion compared to many other newbs I've seen.
Subtle changes I would suggest just from a glance- I'm liking how your trying to stay lean & supplement with the CFL's.
I would get something around a four foot 4 bulb to 8 bulb T5HO or another type of 4 foot tube fluorescent and supplement with 10-12,000 K bulbs. Then if you could move your CFL's to the mid upper sides of the plants if you can. Then just remember to turn your plants a 1/4 to 1/2 revolution and rotate there positions. Since you only have a few this should be easy and keep your node placement nice and close. That particular LED will not veg a plant IMHO or it will but create a popcorn topper instead of a cat tail. If you had the T5 on it, then you could but it still wouldn't flower like you want.compare to a 450 or a 600 watt HPS / MH light alone above all of them which would draw less power than all of those lights & your all gravy with the ventilation. I would have bought that over the LED but that's me. You could have bought one with a digital ballast than used it at 50% or 75% like I do during veg than let light those bastards up in flower to create those trich's!
Your question- That is the symptom of nutrient lock out. I usually wait until there is a much more developed root base before I start the nutes but I would flush them with just plain water for about three to four days then they should begin to eat again. Young plants are easily stunted. Take some of those black pots you have them in, get a 2 1/2' hole saw bit, drill out a bunch of holes in sides of pots, line inside of pots with weedblock netting, super cheap air pots, roots will be ten times better and when you move them into bigger pots you'll be amazed at how good air pruning works. I switched over to it years ago and have never looked back. I've gotten into a routine of starting my hydro plants in the same pots your using with the air pot holes, using only sterilized soil and distilled water from seed to about arms length. Then I rinse the massive fiberous roots & transfer them to a bubbler bucket for a while until I'm happy all the soil is off them. The simply place them into their final 25 gallon RDWC under current pots.
