Green genes for diy that guy builds some cool stuff,
For prebuilt from what I've seen on these forums and friends,

Timber ( pretty sure renfro the god recommended these)
Gavita LED (couple friends were able to get 3.5ish a light with these)
Lumatek (someone on forum using these)
Chiled (few people using these, I followed growmau5 watching these but I think he's no longer with them)

How large is the tent/room?
Do you happen to know what strain?

The rooms are 13 x 25 i don't remember if it's mimosa or mimosa x something. They were more amazed by Renfro set up lol. The rule of thumb is when you feeding write down exactly what you are doing for the week and increase it slightly keep going until you see burn and dial it back down a bit as for the feed program I know some of the stuff they use

3.5 lbs is quite impressive.
So that is why I was wondering on what space they have 1 fixture.
And a thought of mine is that there might be strains that do better under led. Not because of the difference light, but the difference in leaf temperature and RH.

I tried growing in a tent before I built my room, my yield sucked ass for some reason. My last run sadly I didn't take finishing pics I was just over 2lbs a light. I screwed up on a few things I was under feeding with my nutes for literally 7 weeks. I was running blue dream and purple punch. I learned a lot from that last run. I'm hoping to push over 3 this one

2 lbs is also nice!
How large was your room or actual growing area?
And which light was above it?

Spider farmer s4000 or HLG 550 or 650 seem to be my most easy to access options the HLG 550 & Spider-farmer s4000
are a similar price. Timber don't seem to ship outsider the US

Can anyone tell me which has a higher output the HLG 550 or the s4000.

Also in there any truth in white tents being more reflective for LEDs over silver/mylar.

Any recommendations on a carbon filter + fan for a 4x4 thats not to powerful and preferably pretty quite.

The HLG 550 V2 R-Spec has a higher light output with a total PPF output of 1293 μmol/second and system efficacy of 2.65 μmol/joule. This has been confirmed by third party testing. You can view the report by clicking on "View Report for Output/Efficiency" on the HLG 550 web page.

The Spider Farmer SF-4000 claims a total PPF output of 1217 μmol/second and system efficacy of 2.7 μmol/joule (actually 2.66 μmol/joule according to the specs on the SF website). Many people feel these numbers are a little exaggerated. Without knowing what flux and voltage bin SF used for the LM301B diodes and SF never stating what they used for the mono-color diodes on their boards, it's hard to say for sure.

Stick with these brands ^^^. The Black Dog and Phytomax are exactly as you described and not worth the investment.

This will flower a 5x5 nicely. Or you could go the DIY route.

Plenty of people getting great yields from that size space with LED. This is an HLG sponsored thread, but lots of great info and photos. If you jump to the last page you will see some pretty awesome results people have posted. There is also a different thread for Chinese knockoffs, and some other ones for strip builds.

Wrong the blackdogs are not outdated they really are worth it I bought 3 roi 720s and when after a year of research i finally realized that BLACKDOG really does have it figured out better then any other company they have true full spectrum none of the rail lights have any uv a or uv b or major nir also these 720s or gavitas or spyders all use 1 to 3 watt diodes blackdogs use 5 black dogs are actually a white light just look purple because of the uv they also penetrate ALOT better then the rail lights or white light leds because they use 5 watt diodes they really are the best most people just dont have the money to do comparisons or the time or care enough to really try to understand what the difference is. The black dogs are like a white led with a cmh bulb attached they are the best and they are worth it i will be getting some to compare for sure when i get the money but i can assure anyone considering they really got it figured out.

You might want to use periods and commas and punctuation....

Your story about Blackdog is more a fan's story than you substantiate it.
There are also other lamps that use UV-A and UV-B.
Penetration has not so much to do with watts per diode, but with dispersion.
You say you have done research for a year, but what does that research consist of? For example, how much harvest did you have under your Blackdogs?

5x5 flower space, alibaba 800w led with added IR and HR 3500k spectrum samsung 301b's and osram chips (added IR and HR).CO2 enriched room (minigen pro), 12k btu mini split, 50pint dehumi, Vivosun Ozone Gen. 8 weeks veg, 8 weeks flower up-potted 2 times (final pots 7gal fabric pots), living organic soil, roots organics uprising line dry amendments, roots organics element (dry calmag sup), ewc, compost tea, roots organics HPK, Trinity, Surge, Calmag, soil is 1:1 FFOF:Promix BXM. Built my own 2 tier veg cabinet that houses moms and vegs following run, is panda filmed has a magnetic curtain and is inside the room with the flower space, the room dimensions are 6ft wide, 11ft long, and 8ft tall, fully insulate with roxul and spray foam. I yield over 2lbs under my light and it happens every 70-80 days perpetually because i hang dry my plants from my light as you can see... last harvest was 1100g dried and cured. 20200907_072252.jpg

Also that veg cabinet is 2ft wide, 4ft long, and 6ft tall, i also have a 2x2 utility sink in my room as well so i can easily feed everything and im left with a 2x2 bare space on the floor to walk into lol... its basicall walk in to that 2x2 bare space, look right is veg cab, look left is flower space, look ahead is sink... i have to move the first 2 rows of plants and climb under to hand water all my bloom girls and stand in that only free space to water all my veg ladies. I have all autopilot controllers and hardware to run the room at a propper VPD range according to my temps night and day time. I was from floor to ceiling every time i clear my room... hope this helps happy growing and good luck with your project... the final cost on this whole set up was just over $4500, so close to your budget but i think you could be more frugal then i was and still achieve the same thing.

Quick edit, those controllers also run my lights, my co2, and my rH and my temperature... not just the rH and temp for VPD. I also have my scrubber set to turn on for 15 minutes and off for 45 minutes on a repeat cycle timer so that it scrubs the room of dust and shit once an hour every hour 24/7.

5w/ double diode is better for penetration: 2012s greatest grobro myth...

Weve tried NIR and initial reaction it doesnt do anything really, but we need to see this on a from clone run.
A white led and a CMH bulb is awesome, and much cheaper than a blackdog.
