Please don't start shit between HLG and Chinese made boards, every one has their own ideas and budgets and that's fine. This could be just as educational as any other custom builds, lets see how they grow. Moflow Well-Known Member. Royal Queen Seeds Royal Gorrilla directly under a Growgreen, also gets light indirectly from a qb and meiju Bit of foxtailing. Sensi Star original 10 years old cut from seed 60 days directly under a QB, indirect light from gg and Meijui boards Sensi Star 2 cut from seed, Day 30 ish, directly under a gg board, indirect light from Meiju boards All of them Some will say the Boards are.
Moflow thanks for posting, I thought there was more than just yourself using Chinese boards, I bet you feel so isolated in here lol.Disclaimer: Please check the legal status of growing cannabis in your jurisdiction before you begin your grow.
Hello readers! With all the available grow equipment available, selecting the right products for your grow can be a daunting task. In the GN spirit of providing education and guidance, here are the nine best LED grow lights for you to consider. This one was mentioned by a number of cannabis growers as their favorite LED.
Many reports of higher marijuana yields, lower running temperature, and long life. Note: My top picks for Best LED for your Cannabis grow are based on discussions with professional growers, overall customer satisfaction, and number of positive reviews. Light emitting diodes LEDs are a type of lighting used in plant cultivation. LED grow lights utilize hundreds these surface semiconductors to produce varied wavelengths of light which work together to create the ideal color spectrum for maximum photosynthesis and growth.
Recent technological innovations have made them. In addition to being lightweight, LEDs operate much cooler than other types of lighting, and this can be particularly important when climate is a factor. LEDs also use significantly less energy than other types of lighting which is great for the environment and your power bill. Our best of the best pick, the Fluence Spyder is definitely one of the most robust full-spectrum LED lights on the market. Providing an even light spread and delivering a PPFD of overthis light is ideal for nearly any grow operation.
With its sleek, low profile design, this light is as much of a showpiece as it is a high-quality LED. Also, each Fluence LED is made to order! Think Fluence LEDs for your commercial cultivation or hobby grow needs! The light distribution is fantastic. The plants love it, producing higher quality flowers. I am a veganic grower, and using this highly efficient lighting system is an energy saving plus…excellent product.
Halfway though one run I could tell they were going to replace my w HPS setup. There is less stretch, the flowers are closer together, and the buds are more dense. Instead of hot and cool spots from reflectors and a single light source, I have perfectly even light intensity from multiple sources.
The heavy duty construction allows the diodes to be pushed to the limit! I was looking for more of these but was told that the had been discontinued. The sales person recommended the UVB because it was like an updated version of the and even better. I've been using it for about 3 weeks now and this thing is making my jealous! Thanks CLW! These 4 quantum boards are dimmable to help you save on energy costs during lower light growth periods.

9 Best LED Lights for Your Cannabis Grow – 2019 Review
Reaches 60C board temps at full power Ta 20C. With airflow in tent down to 40CC. Last edited: Nov 19, Apogee SQ and no spectrum adjustment to numbers. So these are minimum numbers. Actual numbers should be higher. Why not a better PAR meter. Stephenj can i have that Lighting Passport now? Budies Well-Known Member.
What kind of application would this be best used in? I like the idea of something like this for a veg rack 2x4. I do really like where this is going, some 5k boards would be great if the cost came way down.
We'll see!These things have created quite a buzz across the usual forums that growers frequent, and for good reason. The LEDs are connected together in series to form strings, and these strings are then combined in parallel configurations to make them compatible with common high-powered constant current drivers like the HLG H-C, H-C, or H-C series. The 2 models available right now are the QB and the QB The number in the model number refers to the number of diodes.
The QB model, with 16 strings, each containing 18 diodes. Boasting efficacy approaching lumens per watt at low power, these diodes are incredibly efficient. Absolute maximum current is rated at mA per diode.HLG Quantum Board grow light test - Horticultural Lighting Goup QB288 V2
Well, you can sort of think of each of these boards as one giant COB. A typical COB has hundreds of individual diodes mounted to its little board, packed very tightly together. Check out my 3-part video review. April 3, at pm. I wonder what the full kits will cost? They must not make much heat or the heat is so spread out due to not need any thermal paste like they claim. Yeah very similar. The Chilled ones are crazy dense.
April 4, at pm. That quantum kit that came back in stock tonight is a good deal, I might just have to order one if I have the funds left over after everything is bought for the outside garden this year.
I wish the w kit came in a or k spectrum though, but just or For sure, they look awesome and the price is definitely right for people in the States. I got my 25x K strips from Digikey tonight. April 6, at pm. Regarding your last question, are you referring to the strip modules I have? If so, there are little notches on the edge of the strip that you could put a screw through to fasten it to a piece of aluminum.
April 5, at pm. Neat that you went over the info on these. I ended up building a few bars using the 22inch Samsung H-series modules in k to light a grow shelf. Very cool. How are your plants doing beneath yours? April 12, at pm. Visually they seem to be doing fine but I wish I had a better way of measuring the light properly. The lux meter is still a good way to check for uniformity of coverage. LED is trickier to convert.
April 17, at am.Intro 2. Buying from Alibaba 4. Growing with Quantum Boards 5. Flower Density 6. COB vs Quantum Board 9. Quantum Boards vs HPS. Quantum boards have the highest photon density per dollar making them the best grow lights on the market. LMb 0. The board is mounted to a metal heat sink for heat dispersion. They produce an appealing white light that allows you to properly view and enjoy your plants. They have over 8 years of transaction history and have excellent customer service.
These suppliers will even laser etch a custom logo on the heat sink at no extra cost. Remember to use the links below to ensure you are dealing with established sellers, there are new sellers that will make fake names e. Meiju vs the real Meijiu. There are rumours floating around that the LMH lights have additional anti-sulfurization coatings to make them more moisture resistant for horticulture applications, but Samsung does not even claim this in their own press release.
This is why all buy links above are for the standard LMb. Their marketing teams will claim that this provides an advantage in output but this has not been proven. I have run Alibaba boards next to HLG with no noticeable differences.
Alibaba trade assurance protects you as a buyer. If there are any issues with your order you can request a refund from Alibaba within 30 days of delivery date.F5 9mm drum magazine
That being said I have found Meijiu and Kingbrite have excellent customer service and will often offer to send a replacement unit if you request a refund. Alibaba lights are shipped globally via air freight which usually takes business days. The shipping rates are calculated by weight so combining orders does not typically result in large savings in shipping.Forums New posts Search forums.

Let me list what I have. Last edited: Mar 11, The driver is good for v in Constant current mode. Then I could dial down the current to ma. That would run about 76 watts The v2 boards are 24v and ma 4 boards are 24v each and ma each. In series. I would still have two v2 boards to do something with Am I on the correct path here?Forums New posts Search forums. What's new New posts New profile posts Latest activity.
