Grower's Choice ROI-E720 PAR Test & Review
Вставка
- Опубліковано 12 вер 2024
- The Grower’s Choice ROI-E720 is a big beautiful grow light. It is an array fixture with 8 LED bars. It offers the best coverage in a 5’ x 5’ grow space of any fixture that I have tested. It has superior efficiency, excellent distribution, and top-quality components. The ROI-E720 is among the very best fixtures on the market for 5’ x 5’ coverage, and it comes in at an incredible price.
Looking to buy the ROI E720? We set up a deal with Grower's Choice partner, TSL Horti Tech. This may be the best deal anywhere for the ROI series fixtures! Shop the TSL Horti Tech Online Store and use 10% Discount Code: CCFC
This video is more than just a PAR test and review! I do an unboxing, show the set-up process and run two PAR tests at different hanging heights. The ROI E720 gives us a great chance to explore the grow light physics of changing hanging height. I show how it affects distribution, Usable PPF, PPFD and Photosynthetic efficiency. I think all growers may find it enlightening.

Grower Love -MJ Coco
Love the comparison when different heights are introduced. These are solid facts ... Much appreciated - keep them coming please!!!
All theses tests make me really appreciate the light spread of the GeekBeast Pro!
Id really like this guy to do a segment on how these lights lose intensity over time. Its gotten alot better but still an issue not many people talk about. I'd like to see a few videos on having these lights on for a few weeks or months and then do a par test and efficiency rating. Bc thats when you see the difference between brands like mars hydro and spectrum king led.
@Jordan Thomas You sound like a terrific guy. Your girlfriend's really lucky.
It's not a issue lol man come on do u even grow gtfoh
@@kingallsup4 lmfao do I grow? Coming from a guy with no grow videos? That's rich. And you obviously don't know anything about led lights. They all loose Intensity over time. That's why spectrum king gives a warranty backed by a 3rd party that their lights won't loose more than 15 or 20% Intensity over a 4 year period. It's all about the design of the light and the parts used. Before you get on here trying to call out ppl attempting to sound like you know what your talking about do some research first. I own 2 roi720s a roi680 and master controller and 4 nextlight mega pros, spectrum king sk402 and sk602 ect. I'm well versed in this field and have actual hands on experience with them. Bottom line your wrong and obviously don't grow.
@@DoctorYo1 lol why bc I know what I'm talking about? And yeah she is happy no mids over here homeboy. You guys seriously need to do some actual growing and get educated on the subject instead of just watching videos and taking it as gospel.
Yeah the lights degrade, as do all lights, but it’ll take atleast 5 years to reach a point where the LED degradation will actually affect plant growth
Just purchased 20 of these lights can't wait to hang them
How did they turn out?
@@stevep4236 Just harvested not too long ago they are definitely worth it You won't get as much as a DE LAMP but the savings will make up for it
@@pastorpescador2598 add some supplement
Awesome dude! I just got 6 of these units so I pumped to hear this. Could I ask you a few ?s about these lights if you don't mind..
I have this light and its like having the sun in my tent
is it cold white LEDs or is it more yellowish white
@@cloud9tk95 white
Love mine as well!! Glad to hear I'm not alone! Lol
Love this light,bought two and just ordered the controller and uv bars I didnt get the first run. Can't wait to see the difference Boost and uv's add from the first run of just the lights.Gonna be very good,hitting almost 5 with 2 lights so far.
Insanely nice , I like the map at 50% at 15”
Perfect for veg if these lights are but too but stacked in a row . No need too run 100% in veg at 22” . Thanks for this
these are what I've been trying to research.
So many damn choices. I bet they would all work fine just as a hobbyist it's allot of money to spend so I want to be sure I'm making the right choice. I really do appreciate any and all help.

Thank you! I've been waiting for your review of this one to hear your opinion. Bought mine about 2 months ago and I can't recommend it enough. Hearing your opinion just backs up my feelings on this light! I will definitely be buying another one from Grower's Choice. Also thinking about buying one of their 500w CMH. Killer products and an awesome company 👍
I am personally a fan of the samsung 301b and Osram boards. The new Mars Hydro SP-3000s are amazing. Bright as hell, and so much more versatile compared to these style of light Going to fill a 5x5 with 3 and a 5x10 with 6 . Even 2 is enough in a 5x5.
Nate Schmidt how ya liking the light?
I bought 4 after I watched this video! Keep up the great work!
Awesome - they are great lights. You and your plants will be happy :)
another great review u and shane are killing it growers love from canada
I have been running the Mars fc6500 in a 5x5 , went from a double ended CMH 1000 watt , this Mars light is wicked in every way and runs at 22c .....ya I said 22c , I had to put the driver back on the light instead of outside the tent or it would run too cool ! My plants look unbelievable under the bright white light and you can see every little detail , it's more than enough for 5x5 I looked at the Grower's choice and other's but all things considered ($) went with the Mars but I'm in Canada and even this budget light was $ 1400 all in but it's worth it , I'm going to get the fc4500 too , if you got the cash buy the best .... whatever that is , but im 67 years old and started in 1975 , with a 400 watt warehouse light so all these new options are awesome , can't go wrong ! Unfortunately whatever you buy will be old news in a month ........just pick the best you can afford !
I'm running the FC3000 in a 100x100cm (big 3x3) MarsHydro tent and it is just the same (see my channel for the grow diary). Even with the driver in the tent, it is running crazy cool. And the brightness and distribution of the light is astounding, especially when it only draws 295 Watts! The Mars FC series is an incredible advance in capability and price.
@@BerkshireBudGrows Kool , really cool , I added 3 ,4' t5 ho LEDs horizontal on 3 walls and brought it up to 27c , so I'm happy now and the light intensity is astounding !
I'm excited! Have this light up now. So far man this thing is amazing and crazy bright. Hope to grow some nice dense buds on the next runs, goodbye spider farmers! 😎😁
Do you think these are worth the extra money over spider farms? Its between these or spiderfarmers for me right now can’t decide.
@DrewZeeGrows yes please let us know what you think about a comparison between the two different lights. ✌😁
@@governmentgangstalkingexpo7192 So far I would say absolutely it's rocking my tent right now. Also their customer service is absolutely amazing compared to SF.
I would get this or the roi e680 and never look back
Hey man, how have this lights been working out for ya? Dense frosty mugs with lots of terps? How many plants did you grow in a 5x5?
Your channel has given me confidence in my future light choice. Thank you for real reviews and no BS, grower love right back to you Dr. !
why in the heck has it taken me so long to find this channel. heard you on the growcast podcast with jordan, and have followed your site religiously but never get into the youtube stuff really. glad i decided to take a look
Glad you are here! Grower Love :)
That driver design is sleek and the first I've seen. Great video 😊
I hope you review and test a Chilled Growcraft light in the future. Great video and I can't wait for the next one.
Dumb question, u know he will
This is a great video about an amazing light! Some day, I hope to have enough room for a monster like this!
Thanks for such an informative and easy to follow video. I made the decision to order this light with the controller. It will be used in a 5x5 Gorilla tent.
How do you like it so far?
@@ast-og-losta Worth every penny!
I'm afraid of not producing enough bud I am doing same setup but only 9 plants
Great video and information!! Thanks for the unboxing! Been looking for a led light and this one just might be perfect 👌
Amazing review keep up the good work Doc.
I’m torn between the Grower’s Chioce & Mars Hydro. Now that I seen what the Grower’s Choice can do I would love to see what the Mars Hydro FC6500 can put out before I buy
Mars Hydro > Growers choice
@@gregwallace6159 geekbeast is better than both
@@jccuchvjvj Greg was right. Now you're right. That Geekbeast is looking better and better to me.
@@Des420 it gives the best, most even light distribution so far
If I could do it all over again I would have went with the Photontek XT1000 Co2. My buddy runs the same organic nutes and uses the same methods as me, same size tent, same genetics, but he yeilds almost double the amount my 720 does with his XT1000. So do your research before pulling the trigger. 🌱
This video helped me decide. Just picked up two of these.
This is a very cool light I appreciate ur tests and efficiency info thank u
It's a BEAUTIFUL fixture. Wow.
Awesome review and thanks for the promo! Just got her ordered 🙏
I have an opportunity to buy two of these brand new for $600 each. I had never heard of the brand but I'm thinking that's a fine deal now.
Interesting... Your maps are better than the maps they list on their own site.
I love your videos. Some scientific data along with personal opinions Growers Luv ❤💙💜💖
I cannot stress this enough try to find these a tour hydro store I got these for 820 a pop out the door tax included

Impressive light and numbers to suit.
Thank you Dr. Coco!

I think I would like to try 2 of these for my next tent, 1x2x2 meter, that should be solid coverage for a very dense grow :-)
Your videos are much appreciate it. thank you so much for the great work I’m wondering if the gavita1700e led is stronger and better?
Same I keep hearing mixed reviews
Do you plan on doing the Marshydro Fc6500 Someday? Great videos!
I do have a question. Did you use the control box? If so the price is off i would think just because the box is extra or am i wrong?? Even just being hooked up not boosting the power?
Crazy seeing some fellow members names in here and on the site lol. Always crushing it Doc!!! Keep up the info!
Testig Phlizon PH-FD8-E would be nice. 600W light with lm301b diodes, Meanwell driver for 425$ shipped with no tax.
Will you be doing a review on the Black Sail Cannon Led in the future?
Great video!
I would love to see a indept review of the geekbeast pro
Its been done on other channels
@@cryptolittle8854 most fixtures are reviewed by other channels . I would like to hear dr coco’s opinion about that light.
@@NoMoreMrNiceGuy223 oh I see what you mean.
GEEKBEAST pro has the advantage in its bar spacing, check the migro review and the ppfd has no hot spot in the middle and super bright edges. That is it's one advantage in design that I believe will catch on to industry standard soon
Cheap beast is not bad no we’re near the best led light though
Have you or will you soon review the G8 C3? I was torn between this ROI and the G8. I went with the G8.
Is there a big difference between the E680 and the E720? Anybody run a side by side comparison?
To be honest, the first E680 is better. The par test of E680 is better than E720.
Would this light work well in a 4x4?
you need to test the Rayonled glmf720 as its been killing it in my 5x5 tents ppfd numbers above 850 even on the edges
Is the Growers Choice e720 ETL listed and DLC approved?
yes. Also IP65 (waterproof).
Would 2 of these lights be over kill in a 4x8 grow tent?
They should run lights up the sides in between the bars... if they did that the map would be so good and if one of these companies were smart enough to do that there light would dominate the market. and would force everyone to step it up so we can get 800 to 1000 all the way around
If I were to do a sea of green also using this light how much plants I can fit in a 4x4
👍👍🤙Excellent info
Grower Love! Thanks for the support TAO
I'm a noob at this but would this lighting system be good for growing tomatoes indoors???
Yeah, sure. You could grow a lot of tomatoes :)
Don’t waste your money for tomatoes. 1000$ is a lot of money for 3 penny vegetable.
Nice 💥👊😎💨🔝🔝🔝✅🔥🔥🔥💚
Hi great stuff guys. You kno when you calculate the min and max yield possible. Is that considering co2 supplemented or would the possible max yield be eveen higher. Also if co2 is used to optimal levels is it true that the usable ppfd increases from 1000 upto 1500. Really appreciate help on this thanks
Dr mj how many diodes are there in this fixture
Any testing on the gavita led fixtures?
Migro did
Would you consider doing a test on a gavita ct 1930e led
A friend of mine made me noticed that black floor of your test box it's very reflective, isn't it better if you use somthig like a black cloth or something that absorbs more light since that the plant isn't that reflective and when you grow to maximize the surface area you use it all and so the ground is covered.
This is a good thing to look out for, but I assure you the mat is less reflective than it may look. The glare you see in the video is exaggerated. There is almost no measurable PAR light reflected off the black of the mat. I am more concerned about the white lines actually, but the impact is really very tiny, well within the MOE. I will eventually get a new test surface and will be able to compare.
Are you trying the sf7000 out by chance?
Pretty please do Spectrum King LED SK603, super ultra instinct thanks. Infinite blessings Dr. Light
What is the potential of yield with a 400 hps in a 2x2? Does someone has a PAR map? ive heard 530 umol usable?
Search 2x2 grower. He get close to HP from 2x2 with LED. So I'm guessing about the same with HPS except you'll have to deal with that heat Ina lil tent.
Would this physically fit into a 4x4?
Barely
Dr.coco how many diodes in the Roi 720
Can I use this in a 4x4 tent?
I just bought 4 of these bye mistake the guys said at the store these are the shit will be my first run someone confirm they getting pretty good yield and what they run a month per light light on normal 3 months
is it has led cover?
Anyone know if I should buffer the coco if I am growing organic? Will cal mag kill my soil?
Micro shadows Holes in the Quantum cubic Chunk room
Any one know what would be better purchase the Growers Choice 720 or HLG 650r
Can you please do a Medic Grow Spectrum X ??? Or look it up to let me know please
Price?
ur suppose to lie down Leds down then after u install u remove covers. got mine for $ 675 otd
How much you think per month per light the higher wattage is why I doubted my self in buying them
Electricity is charged by the Kilowatt-Hour, or kW-h. A Kilowatt is 1000 Watts. These lights are about 750W draw at maximum, so find out the kW-h rate from your electricity provider and multiply it by .75 (e.g. If you ran it dimmed and drawing only 500W, you would multiply this cost by .5 instead)
This will give you your hourly cost to run. Then multiply that hourly cost by the number of hours you will run it in a month for your total monthly cost.
So if your electricity cost say 20c per kW-h and you ran this light at max 750W it would be 20c x .75 = 15c per hour.
With a 4-week (28 day) Veg at 18 hours per day that would be 28 x 18 = 504 hours. Then 15c (cost per hour) x 504 (total hours run) = 7560 cents, or $75.60 for your 4 week veg.
With a 8-week (56 day) Flower at 12 hours per day that would be 56 x 12 = 672hours. Then 15c (cost per hour) x 672 (total hours run) = 10,080 cents, or $100.80 for your 8 week flower cycle, or $50.40 per 4 weeks.
Or basically 1176 (total hours run) x .75 (750W draw) = *882* kW-h used for a 4 week veg and 8 week flower. Multiply 882 by your kW-h rate and you have your cost to run.
Note electricity is not charged by the actual hour, but by the number of Watts used. There will usually be different kW-h rates at different times of the day, or depending on total usage over a billing cycle.
@@victorsupreme214 Thank you for all that info yeah we’re both kilowatt I think it’s like $.31 a kilowatt here in Northern California so I need to put it together I’d be running three weeks at 18 hours and then nine weeks at 12 hours thank you for your help on this
Would this be 1180grams per plant? 😲
Price
Get the experience of top brands at one third of the price
This or the Geekbeast pro? And go..
Geekbeast has the advantage of what I like to think of as the next wave new model standard once pricey brands learn it. They spread the bars in a way so instead of being evenly spaced, there is a gap in the very middle, and the outer bars are pushed further out AND the outer bars have MORE diodes, therefore NO HOT SPOT in the centre AND the edges are very bright with no drop off!!!
I assume this Growers Choice may win in quality overall and potentially lifetime just guessing
We went ahead and bought the geekbeast pro. Along with that we got us a Gavita pro 1700E let's put them to the test🤷💪💕🌱
@@cryptolittle8854 Woah man sounds bright! Which one you like more?
@@plantingthenorth7225 We love them both. The Gavita pro seems well built. It's like someone turned the sun on. But that Geek beast pro is still amazing and still cheaper. We will know more in a couple of weeks

@@cgeno3547 does the luxx run a bit hot because of driver trapped inside with the light? Also do u know what driver luxx uses?
Can you do reading on boost mode? I'm curious now
Nah never run it on that u don't need it. It's extremely hard to keep up with photosynthesis at 1400 ppfd if u flip the ext to go to 1800 ppfd u will never leave your grow room shit moves to fast. If your 1 hour past watering the plant will die, that's how fast u would fry the plant and roots if your late on watering. Under 1000 ppfd if u miss watering by a hour u see major dropping on the plant. U miss by a hour at 1800ppfd your plant will die. You need automation everything. Don't use the ext u don't know wt u doing g. If u hsve to ask him then u don't know wt to do with it.

1000 ppfd at 15 inches isn't all that great. I would have expected that at 20 to 24 inches.
It is a result of the design. The light is well spread out and it is more efficient to run closer to the canopy. Some fixtures have hanging heights of only 6" for the same reason.
@@DrMJCoco The HLG QB648 320W is in the 900-1000 range from 2ft lol. ( In a 2 x 4)
Sure - you can find fixtures with hanging heights from 6" to over 3'. The higher it is hung the more you depend on the reflectivity of the walls and the greater the bonus from running in arrays. In a small space (single fixture) there is a huge benefit to having a lower hanging height. Hanging height alone does not tell you much about the efficiency or the quality of the fixture though. However, it is typical for Bar Arrays, like the E720 to have better distribution and hence a lower hanging height than a QB style fixture. Grower Love

Junk light, bad customer service, fake warranty. Stay far away. Drivers made by HortiRight that go bad. Then ur warranty is only good if you pay the shipping of the whole fixture back to them. These are cheap Chinese crap.
Just gotta say this lights better be dirt cheap, what with unknown and unproven lite chips,they have proven to lose lite intensely early on ill wait and see or just buy top self.
1100 dollar fixture needs a 5yr guarantee that it will still be working. The whole watt listing of led companies has been shady
