LED vs HPS 2021 | 600W HPS to LED comparison 

HPS is far superior and you know it is.

HID lamps aren't better.They certainly bulk your flowers up more but the quality from LED is far better especially compared to HPS like you're saying.@@backupintheday9710

What did u get from the MH roughly? Heat hurts yields so an HID is pointless without proper extraction. Also HPS bulbs so cheap (half MH) did you never ever try one?

@@pedclarkemobile I only used a metal halide in the 70sanf 80s till I found out about other hid lamps , under my old MH , 1 oz , in my 5x5 under CMH 1000 watt de , I got shot ,2-3oz but the bud's were always washed out from heat , quality was good but too many problems with heat and most of all coverage , my Fc6500 bar light is only about 3" from the edges of the tent and every plant grow these same , most hydro shops don't carry hid any more on my area except used ......and cheap !

@@bruceholinight7978 wow those numbers are low! I know genetics have changed alot, since about 1990 hybrids suited to indoors came to market. A double ended 1000w should get 36oz in the right environment... 18oz would be fairly standard in a tent. Big extractor with thermostat, decent substrate & nutrients. Have u tried any hydro systems? Even handwatered perlite & vermiculite can give really vigorous growth. I've been at it less than 10years & tried soil, Coco, hydro to get more yield per foot, been in alot of different locations but even with staff discounts when I worked at hydro stores I never bought an LED (luddite) but friend with same clones got less dense bud & less weight per foot but they saved power & didn't have to worry about hot spells in summer. Different strokes...

@@pedclarkemobile That's 5 plants 3-4oz=15oz , now 5-8oz x5 plants , but I'm old as hell and lazy so not sure of the weight exactly , to sum it up I got about 15oz with the CMH and now 40 oz if m not lazy and mainline everything , anything before about 2012 I had old school stuff and doesn't compare to these new lights and nutes ! I did win two local cannabis cups using the CMH so it is a great light just too much heat and power , only us a 4" fan now ....turned down !

@@bruceholinight7978 ok! That makes more sense! That's a very respectable gram/watt ratio. I was thinking that you'd be running out between chops with a 1kw lamp running! ... No danger of running low with a box+ per chop! Must be a good 4" filter to scrub a 5' tent in full bloom.

Is there a difference in final product HID vs Led?

@@bleirdo_dude Not that I can tell. The Durban Poison I've grown for 7 year's looks, taste exactly the same but I do get a better smelling product & higher yield with the LEDs. I contribute that the significant reduction of heat not burning off the terps.

@@Rob-lj5wy Cool. Thanks for the reply. I always heard of it being a different taste, but never got details.

@Living Soil & Solventless Extracts Damn! Your Nugs are like that. You should see a doctor for antibiotics, or probably castration so it does not spread.

@@gquin9487 I agree the Sun grows great product in a greenhouse but being able to control your environment makes a higher quality product in my opinion. It's kinda hard to do that in winter not to mention some state's growing outdoor will get you a lengthy sentence in prison.

You

Scotts are pretty honest people.

haha!

ur on it

Nice one 👍

I have hops in one tent to use for “problem” girls. It can save flowering plant issues

how did your veg go with led?

@@drobro4396 really well, I run 3 tents led, think the blue is beneficial

@@chrisbethmann3955 Thanks bud. Ive been using LEC for the last couple of years. I just switched to LED. Im just a bit concerned with the veg grow. I noticed after veg in lec my flower would go deficient in flower. Thanks for the info. Greatly appreciated

they are easy to buy from Ireland to Aust...i just did..... they use FEDEX, very reliable. Besides a local retailer would probably add 50% or more.

When you add up running cost and upfront cost you have to run led lights for 2_3 years before you start to see any saving. as far as running cost goes there is about a 30$ difference. I don't know about you but i grow weed and not micro greens. i couldn't care less about that 30$

I also have a 600 watt hps, and i want to get the lumatek 600 ,not the pro but the normal version ,shout i do it ,i am also looking at the 465 watt pro versoin ,my tent is 4x4 foot

@@dutchgrower2971 the 600w is the way to go for your sqft.

@@grettirgrattmards2348 also the normal 600 watt version? the pro is a little to expensif for me😊

@@dutchgrower2971 Honestly the difference is miniscule. The pro version just has more of the far IR Leds. The frame and power supplies are completely identical.

@@grettirgrattmards2348 thank you so much for your info and help , i am convinced i am going to buy the zeus 600 i hope it will bring me good , i will definatly give a review😀

@@jasonfabish189 The ChilLED is AWESOME same genetics and the flowers are tight and big! Very impressed with the new LED light!!

@@jasonfabish189 Yield was good, this was not my biggest yielding strain but 162G off of it was comparable for sure

@@NN-ou9jc hey dude... Just wondered how you're grows have came on recently with the LED light? Did you use led during vegetative stage aswell as flowering? Also overall how did you personally compare the hps lights to the led's? All the best mate

@@aidangallacher9049 Yes it has been recently. I have always run HPS/HM until the last few. I have Led in veg and flower. I will say this about the LED that you need to get a good one for flower. There are many out there but I got the ChilLed from growcraft. Expensive but way worth it. I use my first LED for veg but is not good for flowering. Hope this helps.

@@NN-ou9jc thanks dude! Yeah I heard you have to get a good LED like spend the money... I seen few good recommendations 'zeus 600w pro lumatek' and 'Mars hydro Fc 6500'? It's weird tho like you say Led good for veg stage but not so good flower stage. I've seen ppl say opposite and even ppl say led is better for veg stage but the transition to flower stage needs to be 12/12 off first 2 days with no temp increase then basically 10% increase every 2nd day till 100% and lots of ppl love the led outcome over HMP /MH. Even ppl say their yields increase massively with led!!

You should be using fans whether you need to keep it cool or not. Helps get air to the plants, allows them to grow bushier and larger leaves, and helps to strengthen branches

Same here. I had to move my setup to my basement because more people would be coming in and out and other stuff, but even when its 80 throughout the house its still cold as hell down there. My plants definitely didn't like it at first cuz all I had was an Led but I litterally went out and got an hps to keep the room a bit warmer. That and I felt like expanding and I dont necessarily need a tent with what I bought

Your got cheap power . Try Australia we pay 36cents kWh. We are getting robbed.

@@billyballsup2685 Still better than uk prices 32p kwh with a 55p standing charge each day😱

Nothing stopping you hanging the hps in the room with an LED in winter and turning both down to adjust temp and par readings. I'm going LED this year for cost and par reading across a 3x3ft with a 400watt hps is pretty bad in comparison too. Still awesome used em for years but I'm over the heat exchange issues vs usable light and the bills

I'll use the extra power to run my HPS's thanks. Unless you really struggle w heat or can't pay an electric bill the LED's are useless.

@@funkfarmer7125 your ignorance must be bliss eh! There are so many benefits of LED over HIDs, its not even comparable at this point, maybe a few years ago. Also not to mention the fact that we are now only staring to unlock what spectrum does to the cannabinoid profile because of LED technology. But hey everyone is entitled to their opinion. ... even if they are wrong. Happy growing👍

@@funkfarmer7125 you should try with some modern led arrays, I think you be shocked at the increased yield and flavor

Yep thats what I have most of too but also 2 fluence bio spyders and the gavita 1930 but like my gc 720s

@@jitslifts7748 the CT1930e was pretty disappointing, high heat, has to be set at 8+ feet to get decent coverage, and you need the EL1 gen 2 controller to operate it properly, better off with 1700e, ROI e720, or a Photontek 600 or 1000. 🌱

Ya haven't had a chance to run the 1930 yet but I'll be running it next to my others this next run I couldn't pass them up though some one sold them to me for cheap I basically got three for 1200 or the price of one hopefully its not too bad I was planning on keeping it at 4 feet like it said in the 1930 vids

What's the point? More than 4-5% far red causes stem elongation and artificially increases leaf temp, and only UVb best delivered in pulsing form, aka fluorescent tubes, is helpful to increase terpenes in flower.

Because 730 infrared increases Emerson effect, elongation isn't really an issue if you know how to grow properly. UVA is beneficial to thc & resin production. Its a wider spectrum which is closer to sunlight.

It can help but once I hit 600 of led covering 6x6 didn't need to worry about heat so much vs hps and it was still cheaper to run a electric heater with a thermostat in the winter

Exactly, people don't seem to understand some people actually welcome the heat of the HPS. The cost of cooling them and running them is negligible compared to re-mortgaging your home to buy one LED fixture.

Great question. I wonder the same. Mostly Sun pull them in for darkness

I use led thinking about switching back

Did you try the led out?

@@lemmyrichards9477 ^

Result is??

Well done for disposing of them properly rather than chuck them in the bin, good job my man

@@glennhubanks4729 I bought Mars Hydro, Spider Farmer, and Viparspectra.

Did u burp the bud for couple months in jars.

That’s a really good saying and I’m going to definitely pull the trigger on the second expensive piece of lighting today because of it!

I'm the same, i've always grown with HPS duel spec lamps and lumatek digital ballasts and their older magnetic ballasts. I'd love to get LEDs now they are getting cheaper for better quality lights. I hated the old purple LEDs which were still no match for a HPS. I'll wait another year before i get a LED set up. I did build the same homemade LED board migro used about a year or 2 ago and i use it for rooting clones and i'm more then happy with it for that and i've done some dwarf autos with it and got maybe 10 gram from 2 plants running it 18/6.

Double ended hps imo would out perform older blurple light even though the Lumigrow was top of the line for it's day

@@flyinggoatzcanfly7645 did you ever touch one that’s on?

@@flyinggoatzcanfly7645 how many 150w hps do you need to match a single 700w bar style led? How will the heat be at that point?

@@unclejake1476 The numbers are there., just do the math.

Watched a deal about UV and the photosynthesis process plants use. Marshydro doesn't use these values in UV for best output for the plants. The dark UV red and green with blue boosts the plants growth. It was over a very well known light sensor company called "Apogee" about their new PAR meter and about spectrum.

not the fc-e series

why mars pumped out b.s. for waay too many years. fuc em

I think he mentioned at least twice?

He said 2 maybe 3 👍

i do it 6 times in 3 years.... they lose alot of their intnsity and color after just a few hundred hours.

Depends on the brand. Using cheap 15 dollar bulbs, 4 times a year, using 50-60 dollar bulbs 2 times a year. I know a guy that runs bulbs till they burn out, all the while complaining about low yields and other problems caused by weak lighting.

With a decent digital ballast and quality bulbs, you should change bulbs about once every 6 months (using 'boost' setting or dimming the bulbs tends to shorten the lifespan of bulbs, best to only use the intended wattage for the bulb).

35/80? :D

Sorry, meant perlite to soil mix. 40/60 and 50/50 mix peat and coco.

Spoken like a true dullard. "Anyone who disagrees is wrong." I've used "top tier LED", you can keep them. HPS still reigns in the flower rooms, for a reason.

​@@funkfarmer7125 I know this a year old message but do you only use hps for flowering or have you ever tried cmh ? I was thinking LED for veg and CMH for flowering or would you say just stick to HPS for flowering? The buds under LEDs look great on grow vids (colourful , frosty ...) but are quite a bit smaller than HPS.

but this man didnt stutter once.....?
