The best LED lights we have found are the high powered (3w diodes) quad band lights here: High Powered LED Grow Lights

hi..I’m thinking of using this ufo90 system..can you give me any feed back.Most of my experienced grow friends are sceptical but have no experience of LED.If you have any feedback would be more than grateful..Thanks..steve

This isnt true. The Tri Band is a hoax. The triband companies are removing essential reds for less essential orange. Show me pics of results….then Ill believe.

I tried calling these guys twice and was hung up on both times. The web site has a phone number only and does not indicate which state they do business in. One their home page I read, “All sales final”, and “3 year guarentee”, yet there IS absolutely no other. IMHO, this does not appear to be a legitimate business. Good luck to you if you’re brave enough to do business with them.

Hello TruthHunter,
It is very difficult to compare two completely different light sources. If you look for detailed comparisons with statistically significant samples comparing HPS to fluorescent for instance, you will find that there is very little data available and this technology has been around over 20 years. It isn’t unique to LED grow lights.
Our website provides comparisons via spectral content, cost, electrical use, lifetime, and coverage area- http://www.led-grow-master.com. (Maybe we weren’t flagged, phew.) We are here to answer questions via our toll free number 1-866-414-7244 7 days a week and have over 6 years of experience directly working with Universities, researchers, commercial and hobby growers using LEDs successfully.
You are right about using the HPS to supplement heat if there is no sunlight available. It does increase the growth rates. You can run the LEDs for the full photoperiod and turn the HPS on periodically to heat up the plant canopy.

Other than a story of successfull commercial lettuce operation in Japan using
Red Leds, I don’t see much evidence that this technology has arrived. Without detailed comparisons with statistically significant samples, I would
hesitate to invest. I just can’t find it on the internet.

I am looking for something to speed up Tissue Culture development, but
will probably wait until the tech is more mature. I can’t afford to invest
my money in my own comparisons at this point. That none of the producers of led grow lights publish comparisons, is a big red flag for me.

If you need additional heat to maintain optimum growth temperatures, leds
would be best supplemented by other lights. If you have to air-condition, like
here in South Florida, Leds alone look more attractive.

LED Plant Lighting is here. Methodology is what is behind. HPS took 20+ years to develop. Read about over watering, and changing light sources. Under an HPS it is nearly impossible to over water, because of the intense heat. Over watering was a major issue when people started using T5s, so people put the light closer to give more heat directly to the plants and growth under T5s improved, especially when larger fixtures hit the market. Over watering even once under LEDs can ruin any plant…. Research Please….
Methods must change….LEDer

I have a friend which owns a hydrponic store here in Cali. He at 1st thought LED was the way to go for our hot summers. He conducted a test involving 9 quad band UFOs. He says the same thing I hear from people who have actually used them. Great for seeds, cuttings, babies. Beginning of veg is good than everything goes to sh*t. Oh’ya, the 9 UFOs were over a 4×4 table. They dont have the juice & lack the warmth a plant likes. He told me his mini T5 bar outdoes a 90 watt UFO. Thats 1, 1ft t5 bulb. He did all his homework, growing is what he does for a living. He stressed to me not to waste my money. He said maybe if they come out with high output 10 watt diodes than maybe it will be effective. He said they are great for plants that require a low level of light. I tried to purchase one off of him he already sold a few w/ warnings & the rest are on his friends patio as party lights. I wish they worked, are there any companys offering a 90 day money back no questions asked gurantee. These people aren’t teling you all of these things come from China. They may switch out a couple diodes but the thing was made in China. I wish someone could prove me wrong & show results of a grow from plants with a high demand.

I’m very disappointed that my comments and those of others have been removed without explanation. A free exchange of ideas in a civil manner is crucial to the advance of technology.
