FAQ : LED Grow Lights
12-2009 UPDATE:
Both of the Supernova's (enhanced
and regular),
and the LED
UFO have a 3 year warranty, the first year is 100%
coverage including all shipping costs, then the 2 years after that
are pro-rated warranty, and the customer pays the shipping. We
haven't had any big issues yet, but all of the small stuff that's
come up has been taken care of by these guys in a very professional
manner.
6-2009 UPDATE:
Well, I guess I can confidently say
that the face of Growlights as we know (and love) them is changing.
The Supernova LED growlights really
do work! You'll get very respectable results out of your garden
with these things, and you
won't have to deal with heat!
They are still very expensive, and
growth with them is definitely slower than with HID's, but they are
going to give you very good results! I'd put one of these up
against a 600 watt HID any day of the week.
Now we're bringing in the 'enhanced
spectrum' Supernova's, which we haven't tested against the standard
Supernova, but they should only give us better results in
comparison. My guess is that in 2-3 years, we'll see the big name
companies in the industry putting their name on LED's, and it will
become the best accepted way to grow indoors.
3-2009 UPDATE:
The
Supernova feedback is just starting to roll in, and so far it's
been all positive!
The smaller
UFO's worked really well, but
they weren't quite enough to be a stand alone light. They worked
better when you grouped them in number, or used them in conjunction
with other supplementary lights.
The intensity of the Supernova's is
enough that it put's them into a new middle category somewhere
better than fluorescent fixtures, and not quite as good as HID's in
function.
The only real criticism I can make of
them is that plants respond slower to them in comparison to the
HID's, more along the lines of fluorescent's, but with a respectable
yield from the plants.
Overall, considering their low
electrical usage, and lack of heat output, LED's are heading in the
right direction to eventually overtake HID's for horticultural use,
but they are still very expensive in comparison.
12-2008 UPDATE!
The light we've been waiting for is
here! The LED UFO company has 'evolved' the LED growlight to the
next generation, and we've got them in stock! The
SuperNova is a 270 watt monster
LED growlight using the correct spectrum LED bulbs unlike most of
the other LED growlights on the market.
The
SuperNova is a serious growlight, and casts a blinding
all-purpose spectrum that should easily fill a 3' x 3' area.
It's too soon to say what this light
is equal to in HID wattage comparable terms, but it's at least
three times the output of the original LED UFO.
The biggest thing again, is NO HEAT!
You can stuff this light into any small area without heat concerns!
Check back with us for updates as we'll be getting feedback from
customers, and using them ourselves in the coming months.
WE WERE SKEPTICAL ABOUT LED GROW LIGHTS:
Part of the bad rap that these things are getting is simply due to a
lack of knowledge.
OK, here's my
long-winded opinion on the LED's. We used to have one of those
"Anti-LED!" statements on our website too, but at some point I wanted
to know for myself, so I broke down and paid full retail for two LED
UFO's to test them out. I wanted "friend feedback" instead of relying on
magazine articles, and online forum opinions.
WE NOW SAY
"YES" TO SOME LED GROW LIGHTS:
I hooked up
two of our good local customers with these
LED UFO's. I knew these guys,
and I knew that I'd get good solid feedback from them every step of
the way.
I was sold within
3 weeks after I gave the lights to them just from their feedback on the
vegetative growth.
The young plants responded to the light like they would to
the new T5 fluorescent fixtures. Tight inter-nodal growth, and short
stocky, strong plants.
The plants looked a little different, and their
leaves tend to curl down, but the leaves are thick, and a healthy shade
of green. After that, vegetative growth was similar to what it
would be with a 250 watt HPS light but healthy and progressing normally.
Fruiting and
flowering went the same, slightly slower than normal but healthy and
strong, and with surprisingly dense development. (I recommend adding
fluorescent or HID lighting to improve spectrum output during
fruiting and flowering stages.) And, the fruit and
flowers looked beautiful. The finished results from both of these guys
was an enthusiastic thumbs up, and both of these guys usually garden
with some respectable wattage.
LED ADVANTAGES:
One
LED UFO gives you the results
you'd expect from a 250 watt HPS light.
Yet uses only 1/4 of the
electricity!
Doesn't kick out any heat at all,
so no venting costs.
You start
comparing the positives to the negatives, and they start looking better
and better.
CONSIDERATIONS:
I
don't think LED's are the best choice for
really big plants, or anyone that wants a seriously productive garden,
but for houseplants or a nice hobby garden (or heat-free summer garden) they work
really well.
We're on the first
true generation of these things, so I expect they'll only improve as
time goes on, and hopefully the prices will come down as the new
fixtures come out. It's probably only a short matter of time until
you'll see a Hydrofarm LED, and a Sunlight Supply LED hitting the
market.
NOTE:
Then, you've got a bunch of people trying to capitalize on
the popularity of LED's by selling them on EBay, but these guys are
selling junk. To the best of my knowledge, there are only two brands on
the market that are actually using the correct bulbs - the
UFO, and another one called the
Procyon100.
There are
some fake Chinese fixtures on the market that look the same as the LED
UFO's, but are cheap imitators. These fake UFO's don't have a separate
ballast box, and only come with a one year warranty. You can find them
on EBay for a little less money, but they're a rip-off and won't work
well because they have the wrong bulbs in them! Some of the negative
forum opinions are probably written by EBay shoppers that didn't do
their homework or wanted to save a few bucks. LED's haven't taken the
place of HID's, and may never take their place, but if you use the real
thing, I'm convinced most anyone will like the results.
