lets see if the superglue holds my glasses together this time!
my best havest indoor was 480g with a 600hps
i got beetween 350 and 400 g with it in general
you are very good if you have this result
that is pretty badass! i pulled 1.5 pounds of Green lotus w/ 4 plants in a 4 x 4 x5 homemade grow box under a 600w hortilux super hps. but that's a heavy yeilding green crack hybrid so it literally was the plant, not me. I normally pulled just shy of a pound of normal yeilding indica and hybrid plants out of that space. my best was 3 pounds per 1k input w/ 4:1 ratio of HPS to blurple leds, growing big ole hashplant og hybrids in a room.
Nope not under 100 euro, but hey the Led cobs im already running them more then 6years now every day! My worst score with this setup was still 0,9g/W thats something that still is a challenge under a HPS setup. To me its also the savings
watch out with buying lamps of the brand MARS HYDRO they do use the better quality leds now a days but still providing a terrible driver with their setups and their consumer service is really shitty aswel.
thanks
@quinxstar im not feeling like im very good at all
your scores are not bad brother! I think if you would run a tight setup with clones from 1 mom you can reach 1g/w also in your setup!
impressive yields!, my friend did plug one of my mars hydro 600w classics in at his house a few years ago and the diodes melted upon plugin, supposedly they are alot better now w. the full spectrum white w/ far red fixtures than they used to be.
for the DIY people in North America, Pacific light concepts does good work at providing affordable equippment, and the owner does youtube videos about DIY. so does GrowMau5. I fully recomend people do DIY if they love it or find a as local to them as possible company to get the full spectrum white w/ far red spectrum leds from. this stuff is the efficient future base spectrum we will all be using IMO
Seems this topic comes up every so often.

I agree, if I was going for quickest startup and ROI I too would choose to snag an afforable HPS/MH setup. I built my grow and and a few others off of craigslist purchases of used HID gear. a 1k ballast, and sealed 8 inch ducted hood is 100 dollars together used, a raptor hood(big ole hood) is 75-125 dollars. bulbs at my local hydro store can be bought at 6 bulbs for 100 dollars. if you need to get rolling ASAP its literally the best way to start if you don't have a big pile of cash to help you get started. I do not like heating my house up in the summer, and I do not need to heat my house up to 80 degrees in the winter w/ MH and HPS. I disagree w/ your assesment of it not being worth the investment.
I contacted my local hydro stores that are distributors for the larger brands of LED. growers choice, hlg, gavita, mars, viparspectra, mars hydro, I then contacted each manufacturer w/ my quoted price, and asked if they could beat the store price. the stores offered me 853 each on the 650r's hlg through medgrower1(youtuber who is a distributor) for 800 each. I DIDNT EVEN HAGGLE.
I buy the cheap 6/100 dollar hps bulbs. they only last 3 months before they drop in output. thats 250ish a year on bulbs saved. these lights can run for minimum of 3 years, and likely will last 5 or 6 as people are just now switching from the old models of led to the new ones. If I have my lights for 5 years, I will have saved 1250 dollars on bulbs. then, considering that my space is now covered better, for 37% less energy(before any other fans or AC are factored in). electricity costs 15 cents per KWH here on average a 1k hps costs about 54 dollars a month to run. a 650r costs 34.2 dollars per month to run, that is 19.80 saved per fixture per month, in flower. this is a savings of 950.40 a year for me. if my lights last for 5 years, this is a savings of 4752 dollars w/ the bulb savings it is 5002 saved; add 33% more for veg lighting on all those numbers. Now, consider I was able to also take down a 200w exhaust fan(for the air cooled lights), my AC is now happily keeping the flower room between 70 and 73F instead of struggling to keep it around 75, MY room intake and exhausts for the room itself are now off for 45 minutes at a time and on for 15 instead of 15 on 15 off. my too large of space for single ended hps is now covered more properly, meaning my cost savings are also increasing my yeild. I also purchased some for my veg room, and they are 10/10 leagues above the cheap 1k SE metal halide bulbs in terms of plant response.
I have this many lights in my room. and yes, my eyes feel like captain picard does at the end of that scene even w/ sunglasses and a hat after working under these beasts.
Also, Nice amp! I have an 80s peavey solid state keyboard/bass amp w one of the Behringer tube pedals to drive it a little harder and the Sansamp clone for bass, although the amp is crystal clear and thumps all on it's own.
I may want to reconsider my position on them.
bar style is for low ceilings/stacking vertically w/ shelves/chambers in a tall ass warehouse, board style = hps type shoots light down through canopy replacement whe we are talking about these white w/ far red full spectrum leds.
Take that into account when you make your choice on bar vs board.
If you don't want to make the switch that is on you. I am glad you are not being judgmental as this may very well be the future base type of lighting we all use, and then add HPS or CMH or COB LED and get to alter spectrums to what we want for our plants. my one friend is deciding between vipar spectra and mars hydro's 200-300w lights for a 3x3.
my friend who grows very inefficiently(does not utilize his full wattage, complains about costs) is considering a pair the hlg 225 and hlg 100v2 for flower and veg respectively, as this covers the footprint of his flood tables, 3x3.
My other friend refuses to hear anything about any brand but gavita.
the friend who is deciding between the vipar and mars for a 3x3, pulled 5 ounces out of a 2x2 w/ the 125w vipar spectra 12 band led, or the RBG 3 switch, I forget which) with a mac one caps cut I gave him.
If the brand slaps together the samsung and or osram diodes, even the epistars, runs the meanwell or other quality brand drivers is all that really matters.

Thanks for sharing! I do feel that when heat is not needed, that these white w/ far red full spectrum leds will be very helpful for supplemental greenhouse lighting in cloudy or northern climates! fall and spring when heat isnt as needed as in winter comes to mind as the proper scenario.
Then there is the light spectrum, and initial cost, efficiency, fixtures, space, and electric cost. Sunlight has the best spectrum. It is also free. Hard to beat that. Hence I grow in greenhouse outside.
electrical engineer. I studied light as much as I did electricity at university and as an engineer. A lot of this stuff is just advertising BS IMO. I h only use the lights starting seedlings indoors in the late winter and finishing seed runs indoors the fall if the outdoor weather turns here early.
I agree the sun is the best, but not all of us are lucky to be able to happily grow outdoor even with legalization. I have to deal with smell ordinances. Indoor till I can pull permits for a greenhouse. LED's for light supplementation when heat is not needed, HPS for when it is llater into the fall, or late in winter/early spring while snow is still a threat.
You may enjoy Dr Bugbee's video's that are more like classroom lectures than his more sales pitch type videos. I am sad most of the useful grow light information is in videos trying to sell us products, as I only express brand loyalty based on quality of work and I cant personally validate what's good and what's trash in 99% of video's I want to link, and as I own the HLG lights I don't want to link the videos reviewing them as I don't want to seem like an advertiser when I am not. I just want all of us to be on the same page as unlike you, most of us didn't learn about this at college. I would love for you to assist in parsing out the advertising bullshit and get us to the information in the videos if you have the time.
You may very much like the new spectrum of LED that came out this past year, I was astounded when a spider farmer sf 4000 replaced a 1k Single ended metal halide for veg. I was thoroughly impressed when the 650r's did more than replace 1k SE hps. the spectrum is more similar to CMH, CHPS, or general full spectrum hps/mh conversion lamps, and the plants love it, they penetrate the same as an HPS/MH its meant to replace
for you, and others who use lights like you, including myself, as that's how I start my vegetable garden now so I can have tomatoes, peppers, and cucumbers before the neighbors have even bought baby plants, using MH or HPS for a couple months is far from the worst thing, and it is not worth buying an expensive led for you, and others in the same situation. it would take like 20 years to make the savings pay for the light.
