New Addition

MaxBloom X4



My 2 cents: I really like MaxBlooms X4 Plus for growing cannabis. Combining the standard LED's with the COB for their proprietary 12-band full spectrum is remarkable. They should guarantee their high yield claims because mine showed considerable gains over some of the other lights on my list. The light runs quiet and cool, and its priced to sell. Some other good features are that it's waterproof and it comes with a 5-year warranty which means they stand behind their product. If you are looking for top-notch performance for a very reasonable price, this light is exactly what you have been looking for. My rating, 4.9 outta 5.

    Wow, these are all awesome lights. I always wondered how people grow their plants indoors if they place they live in doesn’t have enough sunlight throughout the year. These lights are the answer. This is especially useful for beginners to just got themselves started. My father wanted to grow some blueberries in the house. It didn’t seem possible, and our winters are pretty long here. These lights will work fine. Anyway, might as well ask you while I am at it. If we were growing blueberries, which light would you recommend?

    • Karl Hosch

      Growing blueberries indoors can be somewhat tricky because they can grow up to 8 feet tall. I would recommend a dwarf species if you want to grow indoors, so they are manageable. They need at least 6 hours of sunlight each day which would equate to 8-10 hours a day under a LED grow light. With a dwarf species you can go with the 300 watt Meizhi light placed 24″ above the canopy. With growing regular blueberries you can go with one 300 watt Meizhi and two supplemental 45 watt Roleadro lights placed at 24″ above the canopy. This will allow you to direct light onto the entire surface or canopy of the plant, ensuring optimum light conditions for indoors. The reason I recommend the Meizhi light is because because it’s the lowest price and the PAR output is sufficient for blueberries. You don’t need the intensity and duration of say cannabis or cacti so less is best. I wish you a successful harvest and if you need any help, feel free to contact me anytime! Thank you! 


  2. Thanks, Karl. I’m going to be in the market for some grow lights soon because my state will legalize medical marijuana in 2018. It looks like that Galaxyhydro is an outstanding deal! Thanks again for putting all this information together. It might have taken me years to ferret it all out.

    • I’m glad I could help. Yes, the Galaxyhydro 300w is a good light to start with and it’s reasonably priced too. I own a few of them and they work perfectly. They have good coverage and are good in pairs depending on how many plants you plan on growing. If you ever need any help growing, just come on back and I’ll do my best to help you out. Thank you for stopping by!

    Hi Karl,
    I have been a gardener for many years, and lately have started an indoor garden. You did a great job explaining how good these LED lights are. I have been doing some research on them and your description is very detailed. I am going to invest in a few of these lights for my garden room. I was worried about burning my plants with such bright lights but these seem to be safe (any thought on that). Thanks again for all the great information and I can’t wait to try them.

    • Karl Hosch

      They are very safe. A lot more safe than HPS lights which give off a LOT of heat. Plus, they are meant to be indoors. Which light you need depends on what kind of plants you intend to grow because they all have different light requirements. No matter what, I have something to meet your needs. If you need any help or would like more information, please don’t hesitate to come back and see me. Best of luck with your indoor garden!
