Horticulture Lighting Group HLG 65 V2 4000K Quantum Board LED Grow Light Veg & Bloom 4000K | Version 2 High-Efficiency Upgraded Samsung LM301B LED's

This is a great light for the price. I own other lights from HLG and the quality has always been top notch! I used this in a 2'x2'x4' tall tent to start some clones, and I also started a couple of seedlings a couple of weeks later. The seedlings took off within aa couple of days, and they are starting perfectly. No stretch, or signs of light burn, which are both issues I have experienced using other "Propagation" lights. I have used an Apogee Instruments Quantum PAR Meter to check PPFD, and at 18 inches away the PPFD was right at 150 which is perfect for this application! It is also right inline with HLG's claims. If you are looking for the cheapest light you can find, this may not be it, but if you can afford $100 I would definitely recommend buying this light. If you can't afford it, I recommend saving until you can. Life has taught me buying cheap is almost always the most expensive option in the long run!

This LED is impressive. Everyone that has seen it has said wow, or whoa, or SOMETHING when I plug it in. It seems brighter than a "600 watt" blurple to the human eye, to me. I've never seen any 60 watt light this bright, grow or otherwise. It is really something. I ordered a second. I haven't used it yet, other than playing around so I have no report on how plants like it, but PEOPLE sure do. It is such a natural looking color as well. Like a bright skylight or window. Lastly the surface of it does get warmer than I'd have guessed, but it barely adds any heat to a space. Hours running in a 20x30" tent with no fans and all zipped up and no problems. I'd recommend it for anyone who doesn't mind paying a little bit, for very high technology, and very high efficiency. It's both.

When using LEDs, don't miss where it says"For best results it is recommended to maintain temperature of grow room at 78° F - 85° F"ESPECIALLY for the devils lettuce. These lights produce nearly ZERO heat. If your house is 68-70° F, max it'll get a tent up to is like 74-75 without supplemental heating. In a room, they wont affect the temp at all. If you do not take into consideration getting your air temps to 78° F MINIMUM, you'll be chasing all types of issues that look like nutrients, pH imbalances and everything in-between. Reason is, since they produce no heat, the surface temps of your girls will be too low and cause discoloration, and prevent your soil from drying, disturbing the root system. If you use this light, MAKE SURE you get your grow space to 80° F because 78 is just the minimum to ensure your plant surface temps are acceptable.

UPDATE! A year or more on and my orchids are flourishing. Still highly reccomend these for even low light plants as long as you buy the dimmer!Love this light for my high light orchids. I wish it came in a 5000k version to better suit blooming AND leaf growing, but 4000k will do just fine with some added real daylight. One gripe is that the connection ports are very delicate. I broke one off and im generally very gentle with things. The second port is wobbly but working for the time being. Ill have to solder them back on eventually.Otherwise, these lights are friggin bright- videos and photos do not capture the blinding light at all. I have this light 8in from my orchid now and Ive ordered the dimmer in case I get any leaf yellowing (they seem super bright- which is excellent). Should be ok 8in from plant since there is minimal heat, but always watch your plants and adjust accordingly.Its also just great light to look at unlike other options. It really makes my planting area and decorative pots pop!I realize these were produced for growing erm... herbal remedies.... but they totally need to market more for orchid growers. So slim and unobtrusive for lighting areas you still want to look presentable and not totally kill the vibe of your home decor.Ill be ordering 5 more eventually to cover all my shelves.👌🏻💯😍📸Update: Ive been researching more into PAR of light and have discovered that this 4000k version actually suits my orchids very well as far as useable temperatures of light goes. Very pleased with it besides the connection port being so delicate. Ive already purchased another plus a dimmer for each. Only time will tell how my orchids do under these but I dont doubt they will flourish!

This light is perfect for small grows. No better value if you wanna grow 2 small auto flowers strains at a time. Bright enough for healthy flowers. I have 2 other HLG lights and all are of the highest quality.
