@@mindwis3 Maybe ?, people i speak to have ended up with bad product, have no idea what they used, maybe you can help.... i use a 400 W MH and 400 W HPS, im looking for LED equivelent with the purpose of lowering bills, i dont want to compromise on final quality or even quantity of what i currently use, im assuming LED VS HPS doesnt do this ? and can i find an LED that will pull less than 400 W from the wall but still give me 400 w equivelant or better while not compromising on quality ? this stuff head Fu%$s me lol and id imagine given the targeted market for such products i wouldnt be alone

[@mindwis3]

Hi @@johnmcafee9663, finding a 300 watt LED that beats 400 watt HPS/MH shouldn't be too hard. Perhaps rather than directly compare, you can detail the size you want to cover and how intense you'd like the light to be. i would consider going for around 400 watt led with a dial to set the power, that way you can get the same intensity you have now, but you have some headspace too if you turn up the power. The link below is a direct comparison of HPS/MH vs LED by Sean, who has been selling and advising on that stuff for a decade.. he knows his stuff really well. please have a look at the clip below and things will get clearer i promise :) kzbin.info/www/bejne/a2LakqKIidShmZo

[@modernfiddler5475]

@@blackbird69xxx That depends on several things... What is your budget, what do you want to grow, how big of an area, etc... Spectrum King has several decent options to choose from, Spyder Fluence lights are pretty much top of the line but they are pretty expensive. RapidLED.com has a lot of good options for DIY builds for reasonable prices. The most important thing to look for is a light that has a lot of white diodes that is supplemented with red (620 & 660 nm) diodes, this will give you a complete spectrum. Fruiting and flowering plants will benefit greatly from increased levels of red light. Things like lettuce, herbs, microgreens don't require boosted levels of red light. Familiarize yourself with spectral charts. I would disregard most of what Epic Gardening is telling you, he has a very limited understanding of horticulture LED lighting. chilledgrowlights.com/ - This site is a great resource to better understand the nuances of growing plants with LEDs. Check out their "Learn the basics" links at the bottom of their website. They also sell good horticulture lights as well as components for DIY builds. I hope this helps point you in a better direction. Epic Gardening is basically a glorified commercial showing people the most expensive and wasteful methods for cultivating plants. The light featured here is about 10 years behind the curve in LED horticulture technology/understanding. Good luck to you!

[@riccardocarbo2479]

Thanks for the illuminating video (had to). It explained a lot. Appreciated. My only suggestion is when discussing division, as said, "When you divide 112 into 192, you get 58%..." It sounds as if 112 is getting divided when it's not--it's doing the divide-ing. Like, "Divide 2 into 6." Most will knee-jerk a "3." But it's .66 repeating. It's just much clearer to say, "112 divided by 192." Phrased that way, all fractions can be read from the top, down, with no ambiguity about who's dividing who, which is also the same order you'd enter them on a calculator which is a great tip for folks who run one point short of a decimal. Thanks for the info. I'm from Staten Island.

[@riccardocarbo2479]

@Dave David Understood... my mistake on the .66666!! Yes, it's .33333.... So this is the confusion: It's ambiguous to say "6 goes into two"( parts?) equalling 3, or whether "how much of 6" goes into 2, being .3333333. Yet, both state, "6 goes into 2." Which interpretation to pick? All depends on who's the denominator. Many pick the wrong one. Thanks.

As a beginner, this video was soooo helpful! Especially the beginning. QUESTION: Where do we find the table of PPFD charts? Is it usually on the manufacturers website or in the description of the product?

[@teona74100]

Most manufacturers don't have charts for PPFD, the best option is to contact them directly and ask about it. Still even after they show you the charts, would be a good idea to get a PAR meter which is expensive at, or get a lux meter and do the calculation to get approximate PAR from it, so whatever you get on Lux meter x 100 that and x 0,15 whatever you got, and that's as close as you can get to PAR, keep in mind that this can be a bit off on LED light and is better used on incandescents, fluorescent lights, high-intensity discharge lamps (HID) lights. KZbin is amazing.

[@luisflores3292]

Theres just a flood of knowledge every time! Exactly what we need! It's so strange having this information fill the gaps in my grow game. No insight, to feeling confident about my first big purchase. Thank you a compost heap load!

[@maciekmnyt]

Great video! Except one clarification. About 11:30 you're explaining how the manufacturers rate their lights by multiplying 10W diodes * 100 pieces = 1000W but actual draw is 1.8W per diode. My 2cents: Mfgs are using this 'fake' wattage as a way to compare to the industry standard HPS lights. Don't know how accurate that is but they compare HPS 1000W to their 1000W which actually shows the high efficiency of the LEDs. ('same'(ish) HPS light intensity but with much less power ex. 180W. Yup, it's very unfortunate to use the W(att) terms for comparing light strength. Obviously as you explain there are much more variables with the light spectrum and plant usable light etc. Cheers!

[@epicgardening]

Right that's exactly what I'm saying, they're doing it to be misleading to compare to HPS draw

[@maciekmnyt]

​@@epicgardeningWhat I got from your message is that the LEDs are LESS EFFICIENT. In reality HPS actually drawing 1000W has similar output to leds drawing 180W ACTUAL watts. So obviously same light output with 180Watts is more efficient. (Confusion is that they label these LEDs as 1000W - that 1000W is not the power draw - it is the equivalency of light output of similar HPS light. Those LEDs actually draw just 180W)

[@CR-rc5ch]

Was so glad he added the note @13:00 b/c he stopped doing a similar math progression between the two. He shot straight to 58.33% instead of figuring out the spread across the diodes and then comparing that # to the potential wattage capacity of the LED itself (which equals 58.33%). I wasn't listening to the swipe across the screen and was doing the math on a spread sheet and thought - what is he doing. Pay attention to the slider note and the logic. Thanks @epic for the correction. Great knowledge here!

[@ericawoodland7650]

Wow! This video was done well. Informative content that wasn’t too difficult to understand. I’ve been trying to figure out this whole light thing. Maybe you could do another regarding supplementing light for indoor houseplants. As well as, what all these plant growers mean by “indirect, bright light.” Most of my plants require this. I suppose you’d do the math re: your bulb and then gauge it by distance for strength?? Maybe a video for different plant types and their requirements? And include supplementing when light conditions are less than ideal? Am I making sense? Thanks for the information! By far, the best I’ve seen for grow lights.

Just a white LED bulb? I dont know, it should be at least 3000 lux bright, but I dont know if those lights have quality spectrums too. It is not just the intensity but also de quality (whole electromagnetic spectrum) Eidt: I mean, not really whole, but the visible light to us, 400 nm to 700

[@impIicit]

according to other websites/videos i’ve seen, you’re fine with just white light LED if the plants you’re using the light on will eventually be transplanted outside. the white light is best for germination and seedlings and will be sufficient enough for the early stages and then you’ll need to the other spectrums for fruit growth etc which will be supplied once the plant is transplanted outside. if you’re planing on having an indoor garden from start of seed to finish then i think you may need the other spectrums. i also believe that white LED lights release a certain amount of light from the other spectrums anyways so it ends up working out. mind you this white/day light LED’s will need to have i believe 2-4k lumens and 5000K+ depending on what you’re growing. i’m still learning tho so i may be incorrect.

I am going to be using the light for orchids as well. I am using a cheap red/blue one on an orchid as we speak and I have noticed that it really darkens the color.

[@gabbyjurado98]

If we're using purely grow lights for growing (i don't have a sunny window or a backyard to place them outside) do you have to be on the look out for a certain stage of growth? Do you need to synthesis an experience for the plant? (I once saw a video of a woman slowly pushing her plant around to mimick a storm for the plant) Right now i have a batch of seedlings (4 of each, parsley, lavender, jalapeño, sage, chives, pumpkins) they're growing well and i've spaced them out for their necessary light requirememts and have a medium sized fan blowing on the lowest setting to give the effect of natural wind. Do i need to do anything else? I know with poinsettas you have to plan the dark-light settings in order for them to bloom. Anything like that i should anticipate?

Each covering 2'x2' with very high intensity. Possibly, one Z5 could be hung in the middle of your tent and right below it you place a few high light crops. Just outside of the sweet spot and high intensity, you can grow lower light crops such as herbs and seedlings. Depending on what crop you are growing and what stage it is in, you want to achieve a certain intensity. We have made detailed PPFD maps (light intensity maps) that show what intensity both of our lamp models provide at certain heights. The maps also show how big area each intensity will cover at each height. Uploaded picture of intensity maps: i.imgur.com/23TgEFu.jpg The recommendations on the right-hand side of each map are quite high and are meant to include cannabis which has very high light requirements. It is dependent on what you are growing and what stage your plant is currently in. Personally, I use 150 PPFD for vegetable seeds and younglings until they are at least 2"/5cm tall. I aim for 200-300 when they have passed 2"/5cm in height and only for young adults and adult fruiting plants do I aim for 300-500 PPFD. Everything over 500 is very high intensity and mostly used for cannabis, although it can also be used for fruiting vegetables in their adult state. I hope this was helpful. Let me know if anything was unclear or if you have any other questions.

Super complete answer. Much appreciated

Very informative. Great video. But now in 2022, i need a LED for my 4 x 4 tent. Price is not a big concern, I want quality. Which light do you recommend now in 2022? Thank you for your time.

[@jaaustin500]

I use a lot of grow lights because I live in Canada where we have such long winters with weak light. I've gotten most of my lights from amazon and have had the most success with those advertised as "full spectrum" but after viewing your video I'm not sure if I should trade these in for others which would be even better. Do you have any thoughts about those advertised as "full spectrum"? Also, I remember my Dad using florescent lights in our basement to start seedlings in the spring before planting outside once it got warmer. Do you think florescent lights are even better than the LED (but that they use more energy)? Thanks for all the info! I agree with the others, it's a lot to take in but very important for success! :-)

[@epicgardening]

Full spectrum is hard to answer, you'd have to look at their spectral output chart and make your decision from there. You can certainly start seeds under fluorescents though!

[@chrisflorenca7566]

Hey I'm also in Canada and am planning to do the same, can you please let me know what lights you ended up using? Thanks! 😊

[@elianaselzer5785]

I am not going to claim to be an expert. However I did grow actual “food“ hydroponically for years. Fluorescent light is blue. Which is fine for creating vegetation. But really no plant will begin to flower or bear fruit unless it is exposed to light that is in the yellow/red spectrum. So the answer is probably no. I can’t imagine that you could effectively get your “food“ to flower with fluorescent light. LED lighting generally has a much fuller spectrum of light. So depending on what you did, you would not necessarily have to switch it back-and-forth. I used to switch my crops back-and-forth between fluorescent and HPS.

[@simplifygardening]

nailed it pal. its a shame that they promo them in all sorts of ways that confuse, any company that's listening, get your messaging right and rule the market

[@deathsting1983]

1) get away from bkurple lights 2) PAR is now considered EPAR for extended PAR to include Deep Red and IR obove 700nm. 3) Emerson effect If you want to look at good lights, take a look at HLG or even better, look at the Electric Sky from the Green Sunshine Company.

Nicely done. Kinda looks like a ledtroniks advert though😉 some great info there though for all the ppl who dont know👊🏻

[@adriangough5283]

Thankyou ! Great information and extremely well delivered . One thing i still don't understand is how some manufacturers say that a light has "FULL SPECTRUM". Presuming this refers to 'visible spectrum' of ~400nm - ~700nm, how does this relate to the colour temperature of the diodes being used? for example HLG use a 4000K (i think) diode in their diablo boards which could be referred to as medium in the visible K range . Would there be any benefit to having a row of each say 3500k 4000k 4500k - 7000K ? I understand the nm is a measure the wavelength of light and K color but are they relative ? Or am i completely misunderstanding how this all works .

[@littleminna]

Ok that was way too technical for me. LOL. I just want to know if an Led light is an idea to use on orchids just during the winter when there's not enough light, for just at home. Is it really necessary to have that "aluminium foil" background? I don't like the look of that in my living room. LOL.

[@dallimamma]

Mon Soymon ::: Maybe start with an inexpensive full spectrum fluorescent fixture first?

[@epicgardening]

I would go with a T5 fluorescent for an orchid

[@littleminna]

Thank you so much for your replies. I'll look into that.

Great deep & nerdy explanation. I got the micromoles of PAR per joule - efficacy. I do have a question. Red lights and blue lights have the highest efficacy - but I'll live in the same place with my plants - I need the light myself in winter in NY and red/blue light just doesn't make it for me. It is a poor choice to get a full spectrum light as far as efficacy for the plants while not burning too much electricity when I start my spring propagation? w Light 3x3ft In case you are able to answer - thanks for reading and responding. I had previously thought I would buy the MARS Hydro TS 1000w LED grow light 3x3 - but this may be a product that you were comparing since I see "1000w" consuming 150w with 342 LEDs - this seems to be what you are advocating against. My interest in the MARS system was sparked when I watched a Canadian flower farmer switch to them from their fluorescent system and just blow away the old lighting with dark green, sturdy plant growth. Warmest regards Jennie

[@charlie123866]

strip led are probably the most efficent light at spreading the light evenly..covering a whole area is best..grow lights are designed very badly imo..i use the top bin samsung led but mars hydro have brought out a budget led that is under 200 watts and easily covers a 3x3..3500k with red photon boost diodes.

[@geeklighteva6236]

TOP BIN LM301H+660NM+Cree 730nm ir +Lg 395nm Uv is best !!!
