ViparSpectra KS5000 PAR & ePAR Tests and Review

[@trippyvapors]

Can be found on Amazon for under $400 currently. Crazy deal.

[@krinklyfig]

thanks for the review and especially the testing and efficiency calculations. i just pulled the trigger on this as it's gotten even cheaper with time and competition but it's still a great light. less than $400! used your code and will be here by the end of the week.

[@rosslehmkuhler923]

I LOVE my KS5000! Have come up with some massive harvest's with it.

[@SchlabbRhydah]

Thanks for the solid info....decided to order a KS5000 yesterday based on the info in this video. I will be replacing 2 Viparspectra P2500 and a Unit Farm UFL3000 in a 4x4 tent. This set up does quite well but at 700 watts. Summers are hot where I am so the 500w fixture will be a welcome addition. I was also considering a Mars FC-E4800 or a Kingbrite array. Decided to go with the KS based off of this video as well as the performance of my 2 Vip P2500's! Thanks again!

[@SloppyJoe671]

Just used your discount on Amazon, thank you!!!

[@chadmcdeid]

You're providing an incredible service for the home grower. Thank you from my family to yours. bless.

[@7munkee]

I have an MG 3000 Maxsisun for a 3x3 tent, but I just inherited a 4x4 closet. I may upgrade to this light.

[@Highigan]

Great review! Great light! 🙌💚

[@PudgeypHatSeeds]

Very happy with the Viparspectra LED’s

[@abigfatelf_ttv3438]

Excited for tonight!

[@57ashdot]

just ordered 4 of these for an 8x8, can't wait

[@Hampshire87]

How are they going I wanna buy one but hearing mixed comments. ?

[@stevenreece2692]

About time I got xs1500 and love it

[@whobegrowingdoobies4460]

Just won this light from viparspectra super excited to get it up after this harvest 👍👍again thanks Dr MJ coco for always such amazing helpful videos it's so nice to be able to set my light and forget 👍👍growers luv 🤙🤙💨💨

[@bradg1226]

Gday mate how are you finding it? Any feedback appreciated

[@a_reflection_of_yourself]

Very helpful review. I've been looking at getting this for my next cycle

[@AnsonRyusaki]

You should do a updated video on the new Ks5000 and explain to everyone. How & why the light only dims when turn off through a timer or controller. I bought this light because of your review video. So I feel you need to do this justice..

[@jonhutchinson2902]

This videos are great for determining which fixture to purchase. I appreciate it.

[@florganicsorganics]

Viparspectra puts out some really good equipment. Great videos I bought my medicgrow fold8 because of your videos

[@Triangle0ffence3x]

Is this the light with built in timer and digital wattage meter built in?

[@speedygreen7694]

Seen a couple vids on this. Looks like a fantastic light from what ive seen

[@raymafnas47]

Probably won't be able to catch this vid because of work.... but I appreciate your videos my bro . Another thing I live in Guam so that I'm sure rules me out. But keep upbthe great work my friend and may God smile on all your life endeavors. 💯💯💯💯🔥🔥🔥🔥🔥 content my dude!

[@bushman1051]

Thank you for the opportunity to win

[@Flatpickmastery]

This is my first light in a newbie I hope I made a good choice

[@PudgeypHatSeeds]

Excellent choice it’s a great light

[@Eric-dz1we]

Thank you so much just ordered one on Amazon with your discount code 🤪 $446.50

[@dinero3255]

Would the KS500 be a better light for a 4x4 tent than the HLG BlackBird

[@popejoeii]

Hope this one is good. I like VS pretty well.

[@bradg1226]

Hi and thanks for providing great information. I was keen on the migro aray 4x4 but due to cost difference in australia, i think ill get the ks5000 with its simplicity and local warranty for 200aud cheaper...

[@dannyarmata8878]

I got the yuanhui 400w 6 bar 1596 samsung 301b for $220 on amazon. Rather have 2 of them than this. I love the led layout but shud b cheaper or did a 44x44 with 2000+ diodes to hit 750+ in corners.

[@raymafnas47]

Wow! This is one bad boy of a light!👏👏👏👏👏👏

[@bradyridgley6338]

Very good info sir

[@daytonaexpress7160]

Did Mr. Dr. Coco say best in class?! Hell yea viparspectra!

[@jhonwayne1003]

After seeing the feeding schedule I’m a bit confused. Where is week 8.? I see 7-9 10-11 at bottom. I don’t understand.

[@TriStateTrichomes]

What's your opinion on adding additional far red beyond the normal red diodes most LED bar lights include? And your opinion on UV lighting? I only find data on terpene production and nothing on THC content. Need some solid advice before i add to the grow and make some videos on it.

[@twentytwo138]

Hi, i know you'd prefer an answer by Coco but i'll try to answer what i've learned so far. - IR or Far-Red to be more precise: causes stretching in plants, boosts flowering speed and bud production, heats the leaf surface, helps with plants sleeping and waking up (Emerson effect), penetrates deep into canopy, makes the lower branches catch up with higher branches to create a more even canopy, and high amounts of IR can also help with SOME pests if they can't stand the heat, but you'd only get that with the Sun's high IR that goes up to 1000nm, you won't get that with 730nm in LED. High amounts of IR can also make the buds a bit fluffier, which isn't a bad thing if you have high humidity, with more airflow in the buds there is less chance for budrot. - UVA produces more terpenes, flavor and aroma. UVB produces more THC. You need both UVA & UVB together for the best results. Roughly about 15% UVB and 75% UVA but this can vary. For the best results, the UVB wavelength needs to be between 280-290nm because this triggers a certain protein in plants for more THC, and this protein also acts as a defense mechanism against pests, and also acts as a sunscreen so the plant produces more oils to protect itself. Not to say that 310-315nm UVB won't get results, but 280-290nm triggers this specific protein (i think it's called UVR8 or something like that) Also UVB helps to prevent mold and mildew. It will NOT kill an ongoing mold infestation, but it will help prevent it. Although this is debatable because some people say that mold has a defense mechanism against UV that is activated during the day, and deactivates during the night. People say you need to run UV during night cycle to prevent mold. However, mold doesn't grow in the Sun, and the Sun kills the mold even during the day, so personally i don't think it's only helpful during night cycle, i think it's helpful all the time. Don't go below 280nm, that is UVC and it will burn the plants, that is used for sterilization. The best way to use UV is in the middle of the light cycle, let's say you run 12/12 during flowering, you should use UV around the 6 hour-mark of normal light to simulate the Noon or highest peak of the Sun. If you have autoflowers on 18/6 this would be around 9 hour-mark. Start with 15-mins a day, then increase by 15 mins every few days until you see a little bit of burn damage, then decrease the amount of time. The closer the UV, the shorter the time needed, the further away the longer time is needed. UV is best used at the end of the flowering, in the last 2 weeks. The reason is that UV slows down the growth. It acts as a mini-stress for the plant so they spend some energy into recovering from UV. This recovering process from UV stress is what creates more THC and terpenes. But you can use it all the time if you want, outdoors they always get UV. Since UV falls into the blue side of the spectrum, it also makes the plant more compact, and if used for the whole grow period it can make the buds a bit smaller but denser. But with IR this effect is balanced and countered.

[@TriStateTrichomes]

@@twentytwo138 Great info and since i posted this i found a lot of what you have mentioned, mostly through Bruce Bugbee and the effects of red/blue light on plants. As well as the penetration of red and also green photons. However some of what you stated on UV lighting i did not find and i would be interested to learn more and the source of this information. I did find UV and its ability to help prevent mold or even pathogens (seemed very slight). I also found research on how the plant produces secondary cannabinoids to use as a sunblock. There was a single study about THC content increase but it was done on hemp and this was on i believe the leaf of the plant and was a an insignificant change. Bruce Bugbee also covered this study and mentions it has not been replicated in the lab to show an increase in UV. So if you have further data i am all ears and would love to look into it. At this time UV is a no go for me and if far red is added i believe most company's are adding 730 /760 then i don't see it as a great add to value considering the price increase they seem to come with. But i have no experience with them myself. So this is all based on research ive done.

[@jug5469]

Algorithms go wrong in other cases. What are some of the variables of the algorithm?can you explain

[@efren-vm5xn]

could you test this 1000w luminaire

[@brandonmedley4419]

Can you do a video comparison between your apogee quantum sensor and the Photobio advanced par meter? I could only afford the Photobio right now and I’m wondering how accurate it is.

[@bushman1051]

Hello from San Diego!!!

[@bushman1051]

Good luck everybody🎉

[@vincentconsiglio106]

So I’ve been running my light 28” above the canopy. These tests are telling me I’m about 14” too high

[@charlesbattle9481]

So what light would you recommend the KS5000 or SE5000 grow light?

[@bushman1051]

Good luck everybody

[@maxell330]

I really like this light but I really don't like the click knob for intensity of light, I would rather have a smooth dial for the knob. Plus I already bought four viparspectra lights in the P series not to long ago, so I'll wait a couple years to maybe buy this one.

[@jamesmichaelcabrera9613]

Would you get this light or the smart 8 by medic grow?

[@mikeinnj4424]

Another great video but wonder if it would be better to just use 2 of the XS2000 fixtures and leave gap in middle. Any thoughts?

[@theoverthinker5144]

What did you discover?

[@TriStateTrichomes]

Great video! Do you have nay plans on reviewing the New Mammoth LED 800W Fold (future proof)? I currently run my flower rooms with their 800w 10bar commercial series and LOVE it! Would like to see what differences the newer one brings in comparison.

[@coryswinerton3296]

Then go down to 75% and check your PAR reading. As long as you're in the range of 450-600 during veg, you're good to go.

[@steelcitytv]

Just got the 3000 for a 3x3 I got 2 3x3 the 1 has a bloom plus 3000 in it and it crushes and I wanted to try a bar style so I went with this KS 3000 I love that a company finally was like why is everyone making 3x3 lights the size of 24x24 when it should be 36x36 at least this company went with hey we're going to make it 32x32 that way there's even coverage in only four inches 2 in on each side basically of dead coverage but it isn't dead coverage cuz the lights perfect like this is the first company I've seen start making lights that actually fit the tents cuz so many people usually have to put bigger size lights in their smaller size 10 just to get the even coverage and dim it down like you were saying there is advantages to that though in the winter time you can crank it up hotter raise it get that warmth and in the summertime you can drop it down dammit and cut down the heat

[@bradg1226]

I think thats the biggest difference. Alot of lights arent designed specifically for tent sizes. Diode positioning and fixture size play a key role in this to achieve the most even level par possible. Migro also did a great job with their aray series.

[@SATANALEX9]

I don’t understand 301h Samsung diodes and no meanwell driver this is where they cut costs 4 stars ⭐️ instead of 5 ⭐️ almost a perfect light.

[@SchlabbRhydah]

IMHO the Sosen Drivers are just as good performance-wise vs Meanwell. I own 3 Sosen driven lights (2 Vip p2500, 1 Maxsisun PB1500) as well as 7 Meanwell driven lights) - I've found that the Sosen definitely run hotter...but...the fact that you can hang this Sosen outside your grow space I don't mind one bit!

[@coryswinerton3296]

Sosen is up there in the top 3 with Meanwell, and equally as efficient and reliable, just less overpriced.

[@davemas357]

How good is this in a 5 x 5?

i just dont understand why people not only do par readings at 16 inches. Let alone why they wouldnt show 30 - 36 inches like the majority of actual growers will use.

[@DrMJCoco]

I test lights at the height that produces a maximum PPFD of 1000 umol/m2, which is the level that is safe for plant and which most lights are designed to hit. In a grow tent, hanging heights of 12-24" above the canopy are common. Most growers prefer lights that can be hung closer because they run out of vertical room in their tents. At higher heights you get a better distribution, but lower overall amount of light because of reflective and overspill losses. It is fine to run lights higher while plants are growing and then dial them in once the settle down during the flowering period. Grower Love
