I bloomed with 6 of these in a 4'x10' space and got 2.75 lb of straight fire with a minimal organic nute schedule. That's 1.36g per watt with cheap amazon lights! highly recommend these to anyone.
I love this video shane from migro actually made a video today saying the p1500 is better than the xs1500 but your data prove otherwise! Thank you for not lying keep up the great work dr mj coco!
I'm running one along side a bloom plus 1500, with a California light works solar system UVB centered for flower. Both par matched. but bloom plus was 100 stronger center.
I see these grow numbers and start thinking about my outdoor grow, I got pounds outside, I get OZ inside. This is why I am going to run two 1500 lights and a UVB at flower time. The 1500's give the highest pars I have found, my bloomplus at 12" is around 1800 par give or take now thats its older.
Thanks for this! I'm looking at getting two of the P4000 models, as my space is 240cm x 120cm. Have you played with them before? Do you think it's reasonable to expect roughly the same overall high grade as you gave this model? Thanks for the information as ever!
Is there a way to calculate an estimate of the height needed to get a different PAR reading? Say I have seedlings which need 150 ppfd, the regular PAR maps show much higher numbers for lower heights. Is there some way to estimate what height it should be to get closer to 150 ppfd?
The inverse square rule would apply - except in a reflective space that goes out the window. There are so many variables that will affect the PPFD at target (position, distance, and reflectivity of walls - for example). This is true for full PPFD as well as dimmed. The numbers I get it the test will change a lot if I moved the walls around. If your light has a dimmer, it is easier to estimate impact on PPFD with a dimmer than by simply raising or lowering. But you can use both and you dont have to be super precise.
Dude im struggling to get the optimal height and brightness for week one veg for the vp1500. Im burning the leaves. Theyre turning yellow. Ive got a 1mx1mx1.8m tent.
Hey bro just letting you know I had the same problem with mine but I have the 2000 series I put them way too close to the leaves and burnt them So what I did was I turned it down to 55 to 60% and my plants are loving it now which I’m sure you already figured out by now and I also have a 2 x 4 size enclosure I’m just not able to use the ratchet police anymore I have the light to close to the top but I have a short tent I believe it’s around 5 foot tall exactly and my plants have grown which I have five of them in and my 2x4 Lol I was Trying to load the pictures but for some reason it won’t let me good luck on your grow brother
Great video!! I just got 1 p1500 for a 3"x3"x6" grow tent hoping to have 2 plants..I was wondering what other light I could get that would be a good compliment to this one to help the plants push through flower. Maybe one with more UV lighting?
I'm not sure if this is very helpful to smaller growers. I would have loved to see you try and find a hanging height that tries to get above 500 in all squares in the 2x3. You start approaching 800-900 par and you start running into needing more nutrients, Co2, and environment must be perfect. Any newer grower hitting 900-1000 will give them nothing but problems. Yellowing bleaching bad days. I love your approach. I just think its more dialed in for top notch growers with trying to hit those numbers. Please If I'm wrong correct me. My experience doesn't make me right because I cannot account for all the variables in those grows. "Learning in process forever"
Got one for my 2x4 veg for perpetual every 5 weeks, I didn't want to run the Mars blurple reflector 144. Hoping this outperforms for the first 4 weeks. Then into a 4x4 with 2 sp250 Mars which usually gets me 2.8-3.1oz dry per plant
Probably not from this model - The P-series fixtures should all get similar Photon efficiency. You can use the 1.79umol/w that I tested for the P1500 and enter that in the Grow Light Calculator as the Usable PPF (umol/w) with the 200w rating for the P2000.
This is getting a bit TMI. What light equals the results of a 400 watt HID for the same price. Not taking in electricity for the light and heat removal. Most growers know what a HID will do. There are so many caveats with LED’s, it gets confusing. I KNOW results will be good with a 400 watt HID in a 3x3 (or so) space. It would be helpful to just know what LED light(s) will perform equally at a similar price point.
David Priller if it is a low quality driver it will run less efficient if it gets to hot. You could blow a fan on it to keep the heat down and the driver and led would run more efficient. If it stops working from overheating you need a new driver that is not normal for QB led fixtures.
YES! Good eye. The math for Usable PPF is correct (based on 0.54m2). The error is only a typo in the graphic. But good catch - I did not know about that mistake.
@@DrMJCoco hell yah man!😎🤘 I'm excited, I've been wanting a viparspectra for my 4x4 tent just dont know what one to get yet. Can't wait to see what they can do! Thanks for all your info on all your lights been following for a good while now, keep them videos coming!! Much love from Illinois!
Almost as efficient as the spider farmer but half the price. Sf2000 is $300 and only 200w. This is $127 x 2 = 254 @ 300w and better coverage. I feel bad for everyone who over paid for the SF2000
Hmmm, I think you need to consider the math a little deeper... They are both good deals. The SF 2000 tested at 2.05umol/w which is considerably higher than 1.79. Perhaps it is easier to see this in comparing the Usable PPF. The SF2000 got 412umol and the P1500 got 258umol. The SF2000 puts out more than 50% more light. The SF2000 is perfect in a 2x3 space - and as I show here, the P1500 is perfect in a 2x2. Directly comparing the cost, the P1500 is $0.52, and the SF200 is $0.73 per micromole. But that difference in cost is justified by the improved efficiency. Sorry, to perhaps go too deep on that - but I think a lot about metrics to compare lights ;) Grower Love
Dr MJ Coco Awesome thank you for the reply Dr Coco. Is there anyway you would test a kingbrite qb . They are the most recommended light on all forums but no one has done a legit test for usable PPF. You would be the first and I am sure it would bring a lot more traffics to your awesome web-site. Do you know why everyone is scared to test them when they are the most recommend light of the past year?
Basic Cannabis thank for the reply. I was thinking two p1500 vs one SF2000 for a 2x4 space. You would get an extra 100w and better spreed. Every review I see of the SF2000 the intensity of the light drops off at the end of the fixture. Dr Coco is the first to call it out as a 2x3 light. Everyone else recommend it for a 2x4. I almost got the SF2000 but I’m glad I didn’t I feel that it is over priced for what it is with it’s recent price hikes.
Chad Pandapneumonium the p2000 would be closer but 2 p1000 would be about the same. The SF and the 2 p1000 can only flower a 2x3. If you want a cheap light for a 2x4 the Mars sp250 / sp3000 or migrow new 240w would be your best bet. If you don’t mind buying from China the kingbrite 320w quant board or 320w quantum strip would be best.
I think the XS series is a little bit better, but they are pretty comparable in performance. It depends on the price. They are both good options for 2x2
David Cooper Agreed the Kingbrite is the most recommend light on all forums. I have a feeling that no one tested it because it would drive to much business away from companies like HLG, Mars, spider farmer ect.. It’s not good to go against the big sponsors in the industry like HLG, Mars, SF ect.. but Dr Coco seems legit and willing to go against the grain to help support the community.
I have reached out to Kingbrite to test their fixtures. They have not written back. It is possible that they do not want their lights tested. I hope that is not the case - I will certainly be willing to test it and give fair results. I am as curious as anyone about how those lights would do.
@@DrMJCoco I am having these mailed to me I also have an Amazon budget light. I've yet to assemble and use. I can video document everything silently and I also plan on renting a par meter to record the light par of each light at every six inches. Both claim to be lm301h + 660 nm red at 3500k. I will have a volt/watt meter and gave the electricity consumption and will likely par test off that as opposed to the knob idky

Truly doing the Lord's work here
Lol for sure.
Lol preach
After much research I settled on this light thanks to you and Migro . Your code saved me 20 $ Thanks guys and cheers
Thankyou, adding hanging heights for different stages would completely round this out
BTW these are currently $109 on ebay from Viparspectra. Great value at that price!

Hey man can you do a par test on the Viparspectra P2000? Appreciate your content!
What’s the calculation for a 5x5 ? 5 of em! Is it worth it
Dude im struggling to get the optimal height and brightness for week one veg for the vp1500.
Im burning the leaves. Theyre turning yellow. Ive got a 1mx1mx1.8m tent.
I don't think the symptoms sound like an issue with the light - seems like it is an issue with the nutrients or style of fertilization/fertigation

Sounds like nitrogen deficiency or nutrient lockout.

Is the sp250 on your list on the calculator???
I have a question. How much nutrients out of the gallon do I pour onto the plant? Do I use the whole gallon or what? Can someone please tell me
Chad Pandapneumonium I heard I’m not supposed to go by the recommended feeding for nutrients
Yes use the whole gallon anf watch your plants change! Lol
Hey dr coco any chance you will be reviewing the viparspectra p2000?

I got 1 In a 3x3 for veg I will throw a second one in there for flower should be good
I got mine going right now
Can shane test this driver? Its the same on that is on a few of the budget lights and a few of them seem to drop in power at even moderate temps.
You should always keep your lights cool by using a fan, this applys to all electronics
Can you use this light when you seeds are babys
Great video. Will you be reviewing any migro lights?
I just bought 10 for my 8x8 let me go ahead and make it 16 like you suggested lol

Would this be good for a 3 by 3 by 6 for 2 autos?
Yes depending on how big the autos are. I keep 1 in 3x3 for veg and add another 1 during flower when I have a nice canopy
Dr.Coco,for a grow 2x2
better viparspectra serie Pro P 1500 or serie XG 1500.Grazie
Compliments.
The new XS series is an upgrade. I just got one to test. Will have a video report in the next few weeks.
Grazie
Discount code doesn't work
Are you using their website or Amazon? I'll look into it
No UV chips? :(
Too bad in europe even from viparspectra directly these cost double...
Every light is much more expensive. I blew like 150 euro on a p1000 lol
I have a Q...Is it normal that the led lights cut power if the driver gets too hot? Asking for a friend
David Priller if it is a low quality driver it will run less efficient if it gets to hot. You could blow a fan on it to keep the heat down and the driver and led would run more efficient. If it stops working from overheating you need a new driver that is not normal for QB led fixtures.
So where do I get your tools?
I provide links to almost everything in our testing protocol: www.cocoforcannabis.com/grow-light-testing-protocol/

In the 2x3 test you list the test area as .45 it is actually .54
