Horticulture Lighting Group - HLG 300L

Does anyone have any experience or knowledge of the HLG 300L LED lige by Horticulture Lighting Group? I was torn between the vivoson vs2000 or the spider farmer sf2000 for my new 2.5’x5’ grow tent. I was told the HLG was a superior fixture but not sure if the co. was just trying to sell their light.
I have another tent set up and I also have a sf1000 and a vs1000 and have had no problems with either. The HLG is more expensive and just not sure if it is worth more money than either of the other two fixtures.
I would appreciate any direction to help me make a decision. I am not able to purchase this directly as I have to budget and save for it. I just get confused over various manufacturers products and them saying theirs is the best.
Thank you for any advice, I do appreciate all advice I have had from this site in the past also.


You can’t go wrong with an HLG product not to say anything bad about your other choices they are good lights but there you want the best tools in your box HLG is one of the best


Marshydro sp3000 would be absolutely perfect for that size grow space. I use one in a closet that 2.5x5

I also have a sf2000 that I run in a 1.65x3

I started with the sf2000 in the closet and it did work well in the space.

Hlg makes great lights.
I have 2 spiderfarmer lights, the sf2000 and their upgraded “grey” se3000.
So I know spiderfarmer is great for price range.

I dont know alot about vivosun lights so can’t speak about them really…


HLG is a top tier lighting co. Spider, Mars, Vivo and others are bottom of the barrel cheap junk China lights.

I respectfully disagree. They may not be on the same level as HLG, but they certainly don’t deserve “Bottom of the Barrel” status. Some of their early lights were of the Blurple variety, but current selections are not awful.

NO there bottom of the barrel POS China Junk! And I limit my exposure to China junk and those that support them as much as possible. While HLG and others use leds and drivers made in China. The boards are north American and the lights are manufactured in the USA. I personally haven’t bought anything at Wal-Mart since Obummer was elected. And I think Nixons grave should be pissed on daily for kicking the China door open and Sam Waltons grave pissed on daily for walking through the door. China is a knock off copy cat POS country that should be eliminated from the face of the earth along with there supporters!

I am leaning toward HLG fixture as many have recommended it. I do have one each sf1000 and vs1000 and have had no trouble during and excellent grow. I need a fixture for my 2.3’x5’ tent and this HLG300L has been focused as top of the line. So, after many recommendations HLG it is.
thank all of you for giving me advice, I do appreciate it.

Congrats! The Rspec boards while not Diablo boards are very good indeed. I upgraded my old HLG 260 gen 1 fixture to Rspec and then added another 260 Rspec fixture for use in my 3x3. And just recently added a 2x4 tent and if one 350R is good two is better. If there is anyway you can swing a 350R do it! I will more than likely be updating my Rspec boards to the Diablo boards down the road when they have another big sale.

Rspec 260’s


You won’t regret your choice. I have the 300 and have only had great luck with it. I use it in my 4x4 with some help. It’s rated for a 3x3 space you it will do you wonders in your 2.5 space. Picks off first 2 plants taken down last week using the 300 1 plant got 5 oz other 4.5 mostly all are solid rock hard bud so that’s my vote. Pic of harvest, pics of of all 4 plants

Just checked out the HLG350R and that will be my choice. I have to budget and save for it, disabled vet on limited income, maybe a month or two but will get this one. Hopefully, they say one will cover my 2.5’x5’ tent with three auto pot 3.9 buckets.
Thanks for the advice you made my mind up as did so many offering this light as one of the best.

Call or email HLG and let them know they have discounts available just for veterans.

I texted a few days ago and they offered 5%, the normal with all companies is 10%. I don’t mind, just need two months saving toward it. My boiler needs service so after that I will be able to start my second grow, first in new tent. My 3’x3’ is just about ready. Tried a bud that I accidently cut off two weeks ago and even though it wasn’t ready and still a baby it kicked ass, can’t imagine what these full-grown babies are going to do.

GROW is a standard 10% discount at check out. And DUDE is 15% I think. They run specials from time to time with 20% and even 25% off codes or sales. Best I’ve got was a one time 30% discount code and that was because I was buying a light and donating it to a worthy grower that was doing a great grow with a shop light and standard light bulbs. Blew my mind what this grower was getting done with nothing…

hope they have a sale in a month or two. I also need one more fan. I already have a spider farms 4" fan and filter and will still need another duct fan. As in my 3x3 I have one fan exhaust and one inlet both with filters.
I have an old photoron unit that I put an LED grow light and two fans, which for the size is overkill. I will keep the exhaust one in there and use the other fan for exhaust with filter in new tent. So, have matts, heaters, humidiers, co 2 canistler, three auto pot 3.9 pots, oscillating fan and now just need one more fan and light fixture. Getting excited.
My 3x3 is about a week away from harvest and I will replace fiber pots in there with two vivoson 5 gal hydro buckets, just to give it a try. Wish me luck!

Hlg led are samsung and not made in china! Samsung is a south korean company. But yes each chip is assembled with top bin in ohio. Hlg all the way. Only thing hlg and china related is there uva housings are assembled in china. That is it. Hlg is king for sure and samsung makes best lefd’s period

Unfortunately…the inventeonic drivers are indeed most likely made in china which is dissapointing but in the end, my money will go to hlg all the way.
