    Outstanding results! Review by Gentleman Farmer
    Overall Rating
    I have three of these in a 2' x 4' x 5' grow tent providing light to three 5 gal. pots with outstanding results. They are better than the 2 x 100W high-grade panel lights I have been using for the bloom phase. I will need to start tuning the total spectrum or lst'ing or trimming to hold back the growth on even what are supposed to be short plants!

    The Growers House service and pricing is unbeatable. (Posted on 2/20/2015)
    Cool and strong lights Review by tentastic
    Overall Rating
    I ordered 2 of these Magenta H350s after trying 2 Purple H150s in veg; I replaced a 600W HPS (in a 4.5'x4.5' tent). It's been about 2 weeks and plants formerly under the HPS continue to grow as expected. A plant recently added to the tent has begun flowering as expected. 2-4ºF above room temp without an exhaust fan (but it starts to smell like dirt and organics in the tent). I am very pleased with these lights. (Posted on 3/29/2014)

    You get what you pay for! Review by LEDWarrior

    I decided to get an H350 to replace my starter LED UFO light. I Immediately noticed the stronger intensity of light from the H350 Magenta. I moved it into my grow room and started blooming my flowers. They turned out bigger, denser, and sticker than my previous CFL, and LED grows! One of these lights is perfect for a 1-2 plant stealth grow. Light also stays cool and whisper quiet while running day in and day out. You get what you pay for with Kessil. (Posted on 2/26/2014)
    Wow! Very Impressed! Review by Professor Pinhead
    Overall Rating
    I have been using LED for about a year. I got tired of cheaply made lights so decided to grab a couple of these to see the difference.

    I haven't even gotten them under my plants yet. All I had to do was plug the unit in and the separation in quality was more than obvious between the Kessil lights and their cheaper competitors.

    I would recommend these lights any day!

    - A very satisfied customer. (Posted on 12/3/2012)
