MARS HYDRO 420W TS3000 Led Grow Lights for Indoor Plants

I have had this light for about two weeks now. The light appears well made and comes with the normal hardware for hanging plus a timer and temp/humidity sensor. I would have preferred those to be an option since I have them already and suspect most growers do as well. For first time growers it's a nice package deal. I have six 3-4 week old plants under it at about 18" and four under a 1500 watt LED and there is a noticeable difference in growth on the plants under the Mars Hydro. I recently purchased a PAR meter and my measurements show an average 20-30% PPFD increase over what I was getting with two 1500 watt LEDs over the same plants at a reduction of close to 150 watts power consumptipon. And the overall coverage is better too. It also generates much less heat than the other LED lights and the silent operation is nice too although the noise was not really an issue for me, but not having fans that can break is a plus. I am considering purchasing another one, but might wait to see how this grow turns out. I am curious to see how well it does in the flowering phase. It is a very energy efficient light over traditional LEDs producing more light for less wattage, which I verified with a new watt meter I recently purchased. However, that is not the reason I purchased this light. That said, I have seen some reviews that suggest the standard two and three chip LEDs are still superior overall to Quantum Board LEDs and if energy saving is not a concern, they are still the way to go. The numbers don't show that to be the case based on my measurements and results so far, so I guess I will know if this is correct about three months from now. It came pretty well packaged in a sturdy box with some wood to provide added support. I did have an issue with one of the drivers not dimming properly and contacted support. They were very responsive and are shipping me a new driver, although I have to wait a month as they are currently out of stock, but they did give me a $10 discount for the inconvenience, which was cool. My initial impression is these lights are better in many ways to standard LEDs and are a very affordable alternative. I am guessing Quantum Board LEDs will likely replace standard LEDs over time. I will know more in a few months and may update this review. If all goes well I will be transitioning to all Quantum Board LEDs. Just not sure yet if they will all be Mars Hydro lights. For now, I can recommend the Mars Hydro TSL series lights without hesitation. Good choice for a first time grower too since you get a lot of bang for your buck. Update Jan 27th Just completed my grow with two of the Mars Hydro lights. Very impressive growth with the new lights. So much so it caught me off guard how much the plants stretched when the light cycle was moved to 12/12. I was not prepared and could have done a lot more bending. I ended up with some light burn trying to get the light at the optimum height. Also, I had two plants under one of these lights and it was just too much light for one plant making it difficult to take advantage of the light output. The next grow I will be using the light with one plant and do a better job mainlining to get more yield from the light. That said, the yield I did get was pretty amazing. Very dense and frosty buds for sure. So some lessons learned. My plan now is two purchase two more of the TSW2000 model which will work better in one area of my room over one plant. That will give me a total of four Mars Hydro lights eliminating all of the standard LEDs I have, yet consuming a lot less power. About 1200 watts versus in excess of 2000w with the Mars Hydro's and standard LEDs. I am pretty jacked about the next grow and can say for sure these lights are worth the money - they will pay for themselves over time compared to standard LEDs and that is fact based on real data. Highly recommended - you will not be disappointed with the purchase of these lights.

I just received my Mars hydro light. I'm not always one to write reviews, but these guys deserved one. And my previous light was a king LED 1200 w, which used a lot of the reds and blues. I have been looking for a higher wattage light because I have been having low performance on my last few grows. I put this light in yesterday in the afternoon on the 11th of February. I checked it this morning on the 12th of February, it's like a switch was flipped on the tomato plant. I only wish I had it before a picture. In the one I showed I had to tuck more branches under the SCROG netting. Because they had moved so high they were getting closer to the light. It runs a little warmer and then the King LED. And the surfaces of it can get, I wouldn't say hot, but warmer than warm to the touch. My only gripe is that it seems to be a little weighted to one side. When I put it in my tent it leaned a bit in one direction. As far as I can tell it's that the third box which is the dimmer switch, and daisy chain box. It's on only one side of the light, it doesn't carry a lot of weight, but it appears to be just enough to make the light tilt. I fixed it very simply by using a small plastic box and adding weight to it, I rested it on top of the light, and it seems to work well. Simple solution. All in all the light is awesome, I can't speak to its longevity, I only just got it, but very impressed at the start. UPDATE I thought I would add an update to my review. It's now the end of August 2021, the light is still running strong. Still works exactly as it did. It's holding up perfectly, have not had one issue yet. Plants grow amazingly well under it. You can also put the light nearly right on top of the plant and it will not burn it. Granted you got to have good ventilation. I'm sure an obvious question people have, I was able to grow fruit that was incredibly dense, and very high in potency. I knew some purists who are very good at what they do, and they did not think an LED could stand up to HPS, and even they were impressed by the final result.

Easy installation, easy to adjust, zero noise, Works great! My plants love this light! Plan on buying another one soon for my grow content channel in the future.

I picked up this little Mars Hydro TS600 for my 2x2 tent and honestly, for the price (~$56), it's a solid starter light. What I like: Super bright full-spectrum light that my plants responded to right away — seedlings pop fast, and veg growth looks healthy. Completely silent (no fan) and runs pretty cool compared to older lights. Easy to hang, lightweight, and uses very little electricity. Great value if you're growing herbs, veggies, tomatoes, peppers, or a small cannabis plant. A lot of people (including me) see nice results in small spaces without spending a ton. The downsides: Some folks report the light or power supply dying after 6–12 months. It seems hit-or-miss on longevity — mine is still going strong so far, but it's something to keep in mind. Warranty help can be mixed too. Bottom line: If you're a beginner with a small 2x2 setup and don't want to drop big money, this is one of the better budget options out there. Just use it with good airflow, don't hang it too close during flower, and you should be happy. Would buy again for a simple grow. 4.5/5 — recommended for starters, with eyes open on durability.

Great light for veggies and cannabis

great for areas where the bugs eat ALL your sprouts! worked well for all the crops, even moody ones.

Very affordable, well made light! Great customer service!

I. The Mars-Hydro TSW2000 arrived well-packaged absent any damage. I have heard growers report their lights arrived dented or bent, and I believe them. For this particular line of LED lights the manufacturers decided to use a thin metal for the reflector as I'm sure this allowed them to cut costs without sacrificing the light's efficacy. My light, however, arrived with its vulnerable edges protected by rigid Styrophoam. My light came with a timer, which would have been extremely welcome had I not already owned one from prior grows, as well as a pair of ratchet hangers. It's always nice to have a fresh pair of hangers since they seem to be universally made from crappy alloy, which rust after one or two grows. The assembly instructions were unclear. At first, I was a little dismayed to see the instructions did not have a step-by-step breakdown. It was basically three illustrated panels with almost no annotations. Fortunately, this is not rebuilding a jet engine. If you just sit back and study the parts for a few minutes you'll realize there aren't too many ways it can go together wrong, but you'll want to pay attention to how you orient the drivers for optimal cable management. Once the new light was installed and turned on to full power, it filled my 3x3 tent with a nearly blinding level of light. This is obviously a meaningless way to judge the efficacy of a light, but nonetheless I was glad it worked and wasn't DOA. My Equipment: 1. 3x3 grow tent 2. Mars Hydro TSW2000 3. 4" 190CFM Exhaust Fan w/ charcoal filter 3. 4L Humidifier 4. (2) 6" clip fans 5. Four 3-gallon nursery pots (sturdy pro-cal type, might even be pro-cal brand) I drill extra holes in the bottom FYI. 6. Digital light timer II. Some additional info for grow enthusiasts: 1. I direct sowed into 3-gallon pots* and used no seed starter or rooting solutions. 2. Seeds planted are a 3-pack of Blue Dream Autos and my last Gorilla Glue Auto seed. I only water the immediate area over and around the seed, wait for it to almost dry up, and then gently water again. All four girls popped by the end of the 4th day. I am 20/20 sprouting seeds in this fashion. Finally, and very importantly, during the seedling stage I set the light at 75% and kept the light 30" above the pots. Any lower or any stronger and they would have suffered heat stress. *Pro-Cal pots with four extra holes drilled through the bottoms for additional drainage. Soil Used: 75% Roots Organic Original, 25% Coco. I find that Roots Organic Original already has enough perlite. I'll add to this review once the plants are leafed out some. III. I am currently mid-way through veg and all four plants are doing very well. I can now confirm that this light is quite strong, and is more than what vegging plants need in a 3x3 tent. At 24" and 100% power the tent climbed into the mid-80's (it's very hot where I live right now, even in the basement, so my extraction fan was a little overwhelmed I think). To remedy this I lowered the power back to 75% and the plants seem to prefer it. I had edge curling on the leaves of one of my plants before backing off the brightness, but that has ceased. At this hanging distance and power level there is zero stretching and their growth has continued unabated. I'll update this review during flower, and again, one last time, to report yield. IV. Plants are now in mid flower and have stopped the pre-flower/early flower stretch. I still consider myself only a late-beginner/intermediate grower, having only grown 20 plants so far, including these, but so far these plants have the best internodal spacing of the plants I've grown. Up until now I've used only two different burple brands--and they've worked--but they tend to invite stretching because their wattage and spectrums were not ideal. If anything, these lights are inhibitory for stretching because they include plenty of blue light and at least in my case, for my current phenos, the light is strong enough so the plants don't want to get closer than they have to. This has made for some pretty compact budding sites. I'm excited to see what the colas will look like in another few weeks. The TSW2000 is obviously strong, and provides a nice, bright sun-like spectrum. I believe it will prove out to be an ideal 3x3 tent light, as it is clear now it would have completely flowered all 9 square feet of my tent if I had added a 5th 3-gallon pot, which I plan on doing next time for sure. How big will the buds be? How much will its dry weight end up being? Only time will tell! I'll add a final section to this review once it's all chopped, dried and weighed. V. My four plants have been chopped, dried and cured. The yield of each plant was fairly uniform around 2-2.5oz. Total yield was 9.6oz of buds. Popcorn buds would push it to 11 most likely. The Blue Dream'atic potency was subjectively believed, by two different heavy cannabis users, as slightly stronger than the Gorilla Glue Auto, but both were considered quite potent. I barely smoke so of course both were quite strong to me. I generally only do edibles. Conclusion: This light is more than adequate for the home cannabis grower, and an excellent upgrade for anyone currently using old-school burples or other lesser grow lights.

K well I can't find a downside to this light. It really doesn't leave room for shade at all. It casts such a massive light down where it counts. If plants could smile, I bet mine would be all tickled green with joy. My tent is terribly undersized for this light and to that I say YAAAAAAAY! Really happy and I haven't even given it 24 hours yet. I was wondering if I may have overdone the size of light for the tent but I can also dim them if i think it's too much. And besides, many other growers also say you can't have too much light when you want quality flowers. Now why would I not listen to the professionals. This is my first indoor crop and my second grow ever. Not a pro at all but I'm definitely a good listener. I added a pic of the size difference between what I had and what I've got now. It's 4 times the size and crossing my fingers it'll be close to 4 times the yield. Will add another review after a month of growth to see exactly how they're doing. -Update 1 month later. The last pic is the most recent one and is 1 week after switching to flower. Very satisfied with the light. Again, probably overdid it with the light for the space but I can say with confidence there are definitely no shadows in my tent.

Light arrived where I am in Oz < 5 days after order. Was packed in 2 boxes - the second one was a little excessive in terms of dimensions, but it was well-packed. The accessory hangars/cord pulleys work really well. Appreciate the AU plug - it's actually a standard 3-pin IEC C13 connector, so replacements are easy enough to fine. Had a tiny bit of trouble plugging the power into the light array, so be aware that the hole drilled for the plug at the side of the unit is a very snug fit. I wasn't pushing it through firmly enough at first, but I gently held the other side of the plug receiver, gave it slightly firmer pressure and it went through and stayed snug in the socket. I find it a little strange that you get more info on this Amazon page than you do the Mars Hydro site, but check their recommendations here for light intensity - e.g. 25% for germination. I've got the light hanging fairly low at present, only 35cm from the top of the plants, so I've got it set at a bit over 15% (checking for about 8000 lux using a phone-based light meter, which is accurate enough). Anyway good product, seems to do exactly what it says on the tin, with a simple, good design with well-made components.

Fantastic purchase. This is not your hardware store LED light. I wanted to replace my 4x 24in fluorescent T5HO with an LED system, and wanted to make sure that it used less power, was at least the same brightness, and cost roughly the same. This MARS HYDRO TS 600W uses 97 watts (compared to 250 watts for my T5HO set-up), costs about the same ($111 vs $115 for the T5HO), and it is SO BRIGHT that it makes the T5HO seem like it isn't turned on at all. As soon as I turned it on, I felt this overwhelming sense of "WHAT HAVE I DONE???" because it is just SO BRIGHT. I'm growing a lot of hot peppers, and the MARS HYDRO TS 600W is the perfect light for growing. I don't know how people can even use the brighter ones (TS1000W, TS2000W, etc) without blinding themselves. The light throws off enough heat to bring up the room temperature from 21C (70F) to 26C (79F).

Great bit of kit, just trying to sus the blue tooth connection

Very bright, doesn’t run hot and my capsicums love it so far. Only con is that there is no dimmer.
