Which LED grow light is best for cannabis growing? — 2019 Updated
How to choose the best LED grow light?
If you’re looking for a highly efficient light that is compact, durable and has an extended use life LED grow lights are the best option. They run nearly 70% cooler than the HPS grow lights, which means fewer exhausts in your grow room. They also last longer than CFLs or Halogens, which means you have to replace bulbs less frequently than other light types.
King Plus 1000w LED Grow Light Double
Although it might not always be necessary to have a grow light when growing in a greenhouse, it can help to ensure your plants get light more consistently and help improve growth. This unit from kingLED is perfect for use in either greenhouses or indoors thanks to its excellent cooling system, which helps you to keep your growing space at the right temperature as well as removing any worries your lighting system will overheat if your greenhouse is getting nice and toasty.
Other great aspects of this unit are that: it comes with full spectrum lighting which helps your plants throughout all the stages of the growth process; exceptional energy efficiency; super bright bulbs, and; 100,000 hours of life in the bulbs! The main negative with this unit is the cost, but as you will be saving money on energy costs this should not put you off.
MARS HYDRO COB LED Grow Light CREE 300W
The MARS HYDRO COB LED Grow Light CREE 300W contains a big CREE LED 3590 in the middle surrounded by blue and red CREE and OSRAM LEDs. The light fixture operates without fans but uses a fin heat sink to dissipate heat silently, perfect for the likes of stealth closet grows. For a moderate price you can get this very effective COB LED light, good for any grow setup.
Mars Hydro Reflector Series LED Grow Lights
Mars Hydro Reflector Series lights are some of the best on the market in terms of the quality you receive for the price you pay. Mars Hydro is a leading brand with nine years of experience, and through selling directly from the factory they are able to keep their prices low.
The unique feature of these lights is the reflector design. Each individual LED in these full spectrum LED grow lights has a four-sided reflector cup around it. This increases the intensity of the light, helping to penetrate the canopy even more and to ensure even coverage across the entire grow area.
Viparspectra Reflector Series V450
With PAR values reaching 415 and 655 Viparspectra offers another great LED light. These lights can replace a 400-watt HID and will keep your entire growing area much cooler! It, like the other Viparspectra reflector series models on this list, has both vegetative and bloom switched for light control.
The side range isn’t wanted you would expect for the price, however. Because there are other size options available for better prices the Viparspectra Reflector Series V450 only works if you specifically have a 2.5’ by 2.5’ growing space. Keep in mind that we mention other Viparspectra models on this list, but this model comes up first because Viparspectra seems to cater to those growing with size restrictions here.
HLG 550 V2 4000K Quantum Board LED Grow Light
This is a top-range quantum board LED grow light from Horticulture Lighting Group’s product lineup.
The light has 4 circuit boards, each containing 288 (1,152 total) Samsung LM301B diodes. Samsung is known to produce top-shelf LED quality, so you won’t have to worry if you decide to go with this quantum board grow light. The boards are placed on a larger aluminum panel with a dimmable Meanwell driver on the opposite side.
The HLG 550 V2 measures in at 26″ x 20″ x 3″. It comes with a 120v plug, so you’ll need a 120V to 240V Adapter if your country uses 240v.
If you’re curious, or just switching over from an HID grow light, Horticulture Lighting Group equates the HLG 550 V2 to a 1000 watt HPS grow light.
