  1. 450w review by Derek on 1/30/2017

    After almost six months of research and going back and forth with my naysayer friends I sacked up and used the g8 light in my tent. I was pleasantly surprised at the quality of growth. I did notice the lower electrical bill too and am looking forward to my summer grow season as the temps are way lower with this light compared to my 600w hps I had before. I used bud candy and the 90w flower booster to finish off the grow and final product was deliciously spectacular and heavy.

  2. 1 year with G8LEDs review by Walter on 4/28/2016

    It has been nearly a year since we've put Dorm Grow LED's into our rooms and the results are very positive.
    We have achieved the goals we had when we purchased these lights . Using these lights for a year has shown not only do they perform as advertised but they can take some abuse to. A major short in-between the timer and lights caused that connection to melt, eventually a loss of power to the lights . Repairs were made to the wiring and as We turned on each of the 5x 450w Dorm Grow LED's they came to life showing no ill effects . We did have an issue one of the 2 900w LED's which Dorm Grow covered after receiving the light.
    Electrical usage is ,an ebb and flow system with one 1750 air pump for o2 , three fans, 2x 900w Dorm Grow LED's, 4 x90w Reds, 5x 450w Dorm Grow LED's for $300 a month .
    Yield has increased from 3-4 to 5-6/plant , bud density has improved and they are frostier than ever .
    Dorm Grow Customer Support was great helping us along the way both on the phone and by email .
    These lights were a good investment, one that we'll be improve our quality and quantity in the future .

  3. The results with the 450W review by Meanderthal on 9/22/2015

    The results with the 450W LED are very close to the results with the 1000 W HPS. The LED runs much cooler also. And no ballast is needed for it. Also electric costs are about $30 a month less. For me, it's a no brainer, unless you need the extra heat from the HPS.

  4. 4x4 tent review by Max on 8/24/2015

    The 450 and 90 is all you need for a 4x4 tent. I considered getting a 600 but due to budget restraints I went with the 450 but it still lit up my 4x4 tent. Super duper danky plants. The 90 will be going in this week. Love it! MAX

  5. big buds review by Duke T on 3/16/2015

    I upgraded to the 450w after my trial run with the 240w proved successful. I think this is the perfect size for 6 plants @4ft. You still need the red light and it make a whole lot of difference when I add it for my final 8 weeks. Thanks for an awesome product! - Duke T - IA

  6. Exceptional Quality Grow Light review by LBD on 11/22/2014

    The order(s) arrived in good time and were packed professionally. The lights worked right out of the box no problem, not much heat, but some noise from their internal cooling fans. Plants are responding VERY favorably to the light, demonstrating healthy vigorous growth. It's cool to see the plants photo-trope with enthusiasm towards the G8 spectrum, perking up to absorb it's illumination, and yielding strong new growth every day. I bought a 600W as well, and of course the coverage and intensity is even better. These lights are truly designed for plant production. Great Work G8!!! Thank You!

  7. Very healthy growth with this light review by Jefferson on 5/26/2014

    It's true, the G8LED lights grow healthier plants. i have never seen such good looking plants under any HID or LED light before and I have tried several different brands over the last few years. A long time grower friend of mine recommended this light to me and I had complete faith in his recommendation. He was absolutely accurate in his description. Very healthy plant growth and formations. Tight nodal separation and beautiful leaves and cola formation.

    The whole system is designed by people who understand indoor growing. The flower booster made was very noticeable and positive addition for flowering. The trichome formation was spot on and turned a nice milky color telling me its time to harvest my crop. I yielded 44oz from 6 plants under the 450. Not bad for my first run. Now I am well underway with the second grow and will be adding more lights very soon.

    Thanks - G.A. Jefferson

  8. High quality from g8led review by Kyle on 4/3/2014

    Awesome grow light by g8led. I am using this for vegging 6 plants and they are responding very well to the light. I can see the different wavelength diodes. I like that I can control how bushy or tall the plant can get by adjusting the height at which I hang the light. Overall very good company and product. Great customer service too. Totally worth the price.

  9. The long anticipation for Led tech in flowering finally here review by j.pedicord on 4/3/2014

    For those of you who don't believe in Led for the duration of a grow, keep believing that and leave the secret to us. These lights are absolutely phenomenal! ! I replaced 1000 watt hps with dimable digital ballast, with two of the magnificent G8 Led 450Watts . They are amazing . Led tech is here! !

  10. Perfect light review by Chis J on 3/10/2014

    I saw Grow420Guide have so much success using this light so I got one. I had a healthy harvest using this and adding a 90w red for flowering. Now I am using this light only for vegging because I setup a separate flower room with two of the 450blooms and two 90w reds for even more boost. Getting the extra lights was totally worth it. I have an assembly line style grow operation going. No heat issues and much lower power bills. These guys were really cool too. They answered all my questions and I got the feeling that they really cared about my grow.

  11. I was surprised review by James62 on 1/28/2014

    I am a long time grower since the mid 80's and have grown outdoors when I could and mostly indoors with t5's and hps bulbs as a hobby and business. I have been a LED skeptic for many years but deep down I always did want to test them out but the top brands were always too expensive.

    I came across this kid on YouTube called Grow420Guide and he had documented his grow with the G8-450 LED grow light. It was the proof I needed to give it a chance. I was worried that the price was much lower than I had seen elsewhere but I decided to just try it and find out for myself.

    I have to say that I am truly impressed. I am not going to say it is perfect and the best system out there but it really matched up to my t5/hps system very well, even on the first try. I learned that it is important to add the 90W Red like I saw on YouTube. I saw the resulting difference in budding on a daily basis as soon as I added the light at the start of budding.

    Overall I am very impressed and love the lower power consumption. The G8 technology is something I am going to look into more to slowly upgrade the rest of my grow room.

  12. Best OG light review by Halo on 11/13/2013

    this light was shown on youtube when g420g did an indoor grow with it. awesome to see an OG grow with LEDs - loved it - bought it and couldn't be happier!

  13. Prefect review by Jason on 12/7/2011

    Wonderful grow light for plants, 100% recommendation~ Specs say to use in a 4x3 area but I put it in my 4x4 tent and had no problems. the coverage was great and i had deep enough coverage even at the corners and perimeter of the tent. nice stumpy oak green colored leaf formation and steady growth i could see everyday growing in front of my eyes. amazing technology. i added 2 all red lights at the start of flower and these babies took off! g8-900 is going to be my next purchase
