with the price of electricity set to double in next year or so , having an efficient light is very important for the home grower as well as comercial growers too. really well made video & a ton of info thanks .

I do feel we all being bombarded on youtube by sponsored channels who are telling us we need bigger & bigger lights just because they earn comission for themselves & to sell more products for the light manufacturer unnecessarily...

[@sloopyjoeukr]

Love your channel and a heartfelt thanks for all the help you give to hobby growers! What about light spectrum? Meaning the quality, range of light spectrum and penetration. Isn't this important as well? I think people get too caught up on canopy top light and not realize that light is also needed for the nugs beneath the canopy. I'm not a botanist or horticulturist. Just using common sense which seems to be a dying trait in today's times. I realize that duplicating natural sunlight is very difficult and may only be achieved at great cost inefficiency. The sun doesn't just shut off certain spectrums for plant growth. Is it possible that you run tests with the factors above in mind? I have several requests for the benefit of the community: 1) Compare the quality and range of light spectrum of various lights for a 4 x 4 and 5 x 5. I believe these are the sizes that most people will use. 2) Could you also test Timber Grow Lights, Electric Sky and any other light manufacturers that you think are worthy as well in these tests. 3) Could you test different grow tents for the community? I am unaffiliated with any company. I am only interested in growing the best quality nugs for my money. Thanks again.

Truly amazing information. Can you do an updated test for Marshydro FC6500? They have a more recent version that mimics the FC8000 Diode spacing. It uses 3 rows of diodes instead of just 2 and also condenses the diodes at the sides, while spacing them out in the center. This might just move the 6500 above the 8000.

[@gregkramer5588]

I would think the FC-E8000 would end up very high on this list the way it is weighted. The other light that would have been nice to see would be a pair of Grow 300 lights from Grow Light Science. I think it would be near the top also.

[@RhizeAbove]

Great video with an amazing amount of information, thank you!!

[@lcpgrowers4658]

To me it looks like only the Photontek is really designed for a 5x5 tent. The Medic 8 isn’t terrible, but IME you need at least 600 PPFD to really get big dense Colas. I’d probably run all the others in a 4x4, which would likely get those perimeter numbers up into that range at least. I’d also run that Photontek even without any CO2 (though no argument that additional CO2 will increase yield even further); doubtful it would raise the leaf surface Temps above 30C/86F (which would require supplemental CO2) with only having 660nm Diodes. Finally, I find it odd that Mars Hydro is putting UV and IR/Far Ref diodes on the smaller FC-E models (like the FC-E3000) and not on the larger models like the FC-E6500. 🤷🏻‍♂️

[@DrMJCoco]

Thanks for the comment. I think the FC-8000 also meets your criteria of at least 600 PPFD in the corners. The PPFD limit is not directly related to leaf surface temperature. The PPFD limit relates to the amount of light that plants can process per second. With ambient levels, CO2 starts to limit photosynthesis at about 500umol/m2, which is why we set 500 as the minimal threshold for efficient photosynthesis. Above about 1000umol/m2 the carbon dioxide will become limiting to the point that the plant begins photo-protection responses. The limitation is function of carbon dioxide needed to process the photons in photosynthesis and will occur regardless of leaf surface temps. However, if temp is well out of range there will also be other problems. Finally, UV diodes included on most lights are more for marketing than functionality. UV is much more efficient from Flourescents than LED. Red and IR are more efficient from LED and more important for seedlings and early growth - hence a lot of manufacturers put more red into their smaller lights assuming that they will be used more for early growth.

Some of these lights are 2.9 umol/w in a Sphere test, but that is Total PPF/Watts - the numbers I show are Usable PPF/Watts. The Usable PPF is always lower than the Total PPF, because photons are lost. The number that matters most to us as growers is the Usable PPF = The amount of light that reaches the canopy. Also, I did test the Chilled Growcraft Ultra X3 - It does have a somewhat higher Usable PPE, but the up front cost is significant. Grower Love

@@DrMJCoco thx, wachted the entire video to hear what you already wrote here (thx for the effort). using the greenception gx9 i actually get close to the chilled ultra x3. i did this for longterm purpose, saving energy for climate and some money since we pay like 40 to 50 cents per kw/h.

I've got two of the metagrove old dates love their performance

[@bigpapa8635]

bigpapa 1 second ago You really should’ve included the mars Hydro FCE 8000 in addition to just the FC 8000. I think model would’ve topped your list as far as cost and overall! also why don’t you have the Volt FL - 1? You should definitely test that as I have heard great things

[@sloopyjoeukr]

I just received a notification about a grow light win for a Mars Hydro FC-E800. Is this legit?

[@DrMJCoco]

IT IS NOT LEGIT!!! My account is being spammed.

@@DrMJCoco Thanks. That's what I thought.

Thx it was very interesting

[@jerryrekowski8371]

I don`t know why you don`t test Fluence bioengineering lights since they are the best???

[@loudcloudfarms147]

Fluence lights are mediocre at best, customer service is horrible, I just sold my old spider for 1/3 of what I paid for it originally smh

[@gregadkins8481]

I know that this is a 2 year old video, but I am in Thailand, and if it isn't made here or China, it takes it a while to get here. The Lumatek Zeus 1000w xtreme ppfd co2 just arrived here. Been watching your videos on its European brother. Hell of a light. Here's where I need some help. Given the choice between the Lumatek Zeus, and the Marshydro FC-8000 evo, which one would you recommend? As there, the Lumatek is about $500.00 more expensive.

JUST HEADS UP i purchased a MAXSISUN PRO 2000 it worked for 35 days and stopped . its been a joke try to deal with them for warranty i had to fire up one of my old 400 hps to replace it and its been 7 weeks and the issue is not resolved

[@DrMJCoco]

@@DrMJCoco not any fault of yours , thank you for the offer of help i will be getting all the information off my daughter today as she did the order of the light as they will not deliver out to my farm

[@Helloyapfammily]

Spiderfarmer has a bad customer service as well just an FYI. Mars Hydro is by far thr best China based company in terms of Customer service, i had no problem yet with Gerkbeast using it for 2 months now

[@darcypotterpotter6214]

@@Helloyapfammily i have 2 SP 3000 NO ISSUE AND 3 GROW LIGHT SCIENCE GROW 300 AGAIN NO ISSUES AND 2 GREEN SUNSHINE V3 -180 ALL GREAT LIGHTS

[@Helloyapfammily]

@@darcypotterpotter6214 i dont know what brand and model of lighrs you mentioned, i stand my case with spider farmer and many of us experienced the bad customer service. My main lights are HLG, i run my vegging with geekbeast and on the market for abother brand, going with a chinese manufacturer is a 50/50. When shit hits the fan then its all run down to nowhere, im Chinese and if ever i would buy another chinese lef its marshydro, although none of this could top HLG, but im lovin my geekbeast if its not for the heat

Awesome review 👌

[@brettwayne4583]

Noticed that you didn't test any dimlux led lights. Would have out performed all the above.????

[@FriendsForFriends666]

how come hlg 650r is not up there?

[@DrMJCoco]

Unfortunately, they do not want me to test their lights. Grower Love

[@camthecannaman]

Awesome video as always! Hey man is there any chance u could do a video on Maxsisun's bar style Mg3000? i think maxsisun is a great company but not a lot of reviews on the light yet

[@cjgamer2140]

Would there be any benefit using the FC-8000 with supplemental Co2? Excellent review btw.

[@jamesjackson202]

Not sure it was a fare comparison using a Spider Farmer board light to compare to all the other bar style lights. I think Spider Farmer would compare better if you had used the SE700 bar style light or even the newest G1000W CO2 bar light would have been a much more fair comparison.
