Mars Hydro FC-8000 PAR & ePAR Tests and Review

[@johneybrown8136]

Dr MJ Coco you, by far, put out the most well laid out and comprehensive information on lighting that I have came across in years. Thanks for your hard work and diligent research! Keep up the good work👍 Always look forward to your vids. btw... Your web site and calculators are fantastic!

Looks like an awesome light! Really liking Mars Hydro’s bar style light lineup! Gotta disagree about the research suggesting that 1,000 PPFD is the safe upper range of light that Cannabis can handle though. The research actually shows that Cannabis has no light saturation point (at least up to 2,000 PPFD which to my knowledge is the most that researchers in clinical trials have subjected it to and I personally know people that have gone as high as 4,000 PPFD under LEDs). If you read the research paper published by the University of Mississippi you’ll see that it showed that the Peak Photosynthesis rate in the leaves was reached at 1500 PPFD and 30C/86F at ambient CO2 levels, but the researchers actually found that the rate of transpiration continued to increase up to 2,000 PPFD. What the study actually showed was not that Cannabis requires supplemental CO2 beyond 1500 PPFD (let alone 1,000 PPFD, which is kind of an absurd limit when you consider that sunlight regularly reaches 2,000 PPFD and Cannabis evolved as a Full Sun plant), but instead that CO2 is required when leaf surface temps exceed 30C/86F; which is likely why indoor growers mostly growing under HPS light which emit considerable radiant heat downwards into the plant canopy came to believe that 1,000 PPFD was the safe limit to use without the need for supplemental CO2. This study on the other hand actually tested dry inflorescence yield and found that, while leaf Peak Photosynthesis did seem to top out at 1500 PPFD, actual inflorescence/flower weight yield continue to increase linearly all the way up to 1,800 PPFD and even up to 2,000 PPFD. And this was done at atmospheric/ambient CO2 levels. www.ncbi.nlm.nih.gov/pmc/articles/PMC8144505/ Thanks for the video and review though. ✌️

Man, 5-10 Years Ago It Was Just Cool As Hell To Even Own A Grow Light Period! Everyone Is So Snobby.. I Would Love To Run & Test A Grow Light Like This In My Grow Area 💚🌿 Thank You, Dr. MJCoco, For All The Hard Work You Do To Inform Others Of How Lights Preform! & Helping Others Know The Best Way To Use Each Grow Light at Home! 💚🌿 Much Love 💯

[@Helloyapfammily]

What grow light are you actually using? Well if you are spending 10-20 for a pop of beans, and running every quarter of the year, i guess youll know whats a good catch, its cool what comments on grow lights, it gives the brand some check and balance. Its actually the.same 5-10 years ago, it was actually worst back then, since the.debate doesnt end from HPS, MH, LED etc users...

@@transcendskatemedia9085 Actually not a bad light but youd be on the same page after trying some higher end brands, its like getting your PHD in light science LOL. Id say spiderfarmer though is a red flag when it comes to after sales services you have to watch out for them, although i personally havent tried there lights and my buddy who is a known seed breeder used one unit i know that shit gets hot, which i did order an inline fan from them with a missing parts and they just gave me a middle finger like literally tells me to move on that the itemz are working and complete yada yada...At least Mars Hydro replaced a month used unit. For my budget backup vegging plant i personally used Geekbeast, id also like to try kingbrite and meijiu next if given i have the time. Question have you tried going full power with your lights on summer?

@@miker5700 I was watching the premiere on my laptop, but right before they announced the winninng number my elderly father, whom I care for was hollering at me for help in the other room. I was only gone a couple minutes & my bf called to tell me I won (I chose my birthday 6/19 and I was trying to win it for my bf) We were on the phone and he was giving me the email so I could claim it, but it was given to someone else while we were talking. The crew at Coco For Cannabis was so kind, they offered me a smaller light instead. So I won a $600 prize and lost it all in 5 minutes. I've never been to Vegas but now I dont have to go cuz I know what it feels like. 🤣 Seriously though Dr. MJ Coco was supercool about all this & it's much appreciated.

Mars Hydro FC-8000 or Photontek XT 1000W?

[@fdsffdsf8975]

Does the FC-E 8000 with BRIDGELUX LEDs shine less brightly? Are BRIDGELUX diodes themselves worse than Samsung diodes?

[@miker5700]

Dr MJ has a review of the fc-e6500 and the 4800 you might go check that out and he has review of the fc-6500 and a couple other in that series so might get some more insight if watch them. He really liked the fc-e6500 i remember he was really surprised by it.

[@miker5700]

Both lights will be good the fce has like 1000 more diodes even tho bridgelux might not be ""as good and last as long"" with that many more and same watts will drastically increase life of diodes so they will last long time probably same amout of time. I think either one you'll have great results with

[@BerkshireBudGrows]

could you tell me what amount of heat builds up in your 4x4 with this light and the driver mounted outside ?, looking for 2 lights to fill a 4x8 and would like to keep down on the a/c , would rather use the electricity to add more light, thank you and your work is exactly how it should be done and explained

[@domingogonzales3101]

Ip65 water/ dust resistant?

[@Grinz285]

So do I HAVE to use supplemental c02 for this? What if I don’t.

[@alexmaclean1]

Not at all! From these numbers co2 would help slightly at full power in a 4x4 tent. In a 5x5 the numbers drop below the co2 threshold where it wouldn't really help at all. If you don't want to run c02, which most people will never do anyway, just save some power and run it at 75%, full power in a 4x4 likely wont hurt much but its a waste of money and is just going to make temps higher and put unneeded wear on the light.

[@sineater6609]

A little more info If you run that light in a 4x4 tent without side bracing and you have negative pressure in your 4x4 the sides would be sucked into the light...so will need to brace sides of the 4x4 tent 1st...

Best light yet!

[@coolshirt]

When your testing these lights the leds are working at different intervals. They are never all on full power 100% of time. You would have to hack your grow light and sacrifice it's lifespan to get a real test. Or run the test multiple times in each square until you finds its highest and lowest value. You can see the changes in voltage per led with good eyes.

[@lag1791]

I would love to see a review of this unit compared to the FC-E8000 which uses the good but less $$ BridgeLux LEDs and is significantly cheaper.

I used this light for about a year, then the power connection between the light/driver melted. Lights started flickering and luckily I smelled burning plastic or could have been a fire. Just pay the extra couple hundred dollars for a real light.
