Hi all, Looking at setting up my first grow tent and was about to go for a Mars hydro TS 3000 in a 4x4 when I saw all the HLG praise here. I’m not too concerned about cost for the light, I just want to make sure I’m getting the best for the space. Am I better off with a HLG 550 RSpec? Or the new model 600? Or is the TS3000 the better light? Or is there a better option I haven’t heard of? Thanks all, look forward to your thoughts. ---

650r might be overkill for a 4x4. Think the 550s are for the 4x4. Happy Growing!! ---

I’m using a hlg eco 550 v2 for a 4x4. Super happy with this light. I now own two of them. ---

Thanks all! The 650r does look awesome, and I could always go up to a 5x5… Is it worth it ya reckon? ---

I just bought one but I have not used it yet. The hlg eco 550 gave me over a pound. Any of these lights are amazing it will totally be worth it. I will be using it in a 5x5 that has not arrived yet. I say the more space = more plants = more weight. Just consider on how long you will be growing and if its worth it for you in the end. One thing is for sure you will start out with a bang! Just my two cents! ---

If you’re looking to yield a little more… why not go up to the 5x5? And the 650r will then be the no brainer at that point. I am a little biased…i have two of them. Happy Growing!! ---

Thanks for replying, just looking for some confidence before pulling the trigger. Half the reviews on lights are clearly ads and it’s hard to sort through the BS! HLG are just starting to feel a bit safer than Mars I think… ---

I used to run mars back in the day. I have two 720w lights that were 300 bucks. Of course they were the old versions and not boards like these new ones. They now just sit in the cabinet getting dustier every day…with a bunch of other mars lights…heh ---

did i misread it? i thought a 650r was to flower a 4x4 area. i thought it could veg a 5x5. i dont use a tent so i dont know how that works. thanks ---

You guys are great! The hours I’ve spent trying to figure this shit out, I could be an Electrician by now. I’ve learnt more in a few hours on this forum than weeks of googling, thanks heaps! And any other opinions on best lights for 4x4 or 5x5? I’d love to hear from experience now I’ve found it! ---

The new mars hydro lights are ok. But if you have the money get the hlg. I did a diy build with the help of @dbrn32. Or I would have gone with an hlg light. ---

Neither… I prefer chilLed over hlgs 650r Did a lot of research on LED’s over several months. Compared all the top brands and ended up with the chilled growcraft x6 600 watt.t” ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/6/8/a/68a6c219421b7c92401cc8ab1a0ef48d75f21716.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/a/0/3/a035ee04ac4c978b4c235d1af1b928be6e105a1c.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/e/e/6/ee6f6fe249490cd26a59619d49b9e989b78deba0.jpeg) [Next page](https://ilgmforum.com/t/mars-or-hlg-light/53293.md?page=2)
