StealthGrow SG602 LED Grow
I recently picked up a StealthGrow SG602 LED panel to build out my new medical marijuana grow and see if the new generation of LED panels will meet my expectations. I have 20+ years of experience growing with HIDs and flouros, from small cabinets to a 3000 sq' 20K watt commercial facility (Colorado legal). I'll be straight up though, I need convincing. I've done HIDs forever, and while I'm a tech geek and stay on top of technology, I wasn't impressed with LED grows in 2010 and early 2011. it seems they may have improved a lot. after talking to the reps at SG indepth about the technology and where they have come with it, I figured it was time to try one out. my space requires a low thermal footprint due to high temps in spring-fall and this was also a determining factor in the purchase (my 1000w HID heats up the room to 98deg. the SG602 I have to add heat to get it to an optimal 79deg) - they say the 602 has a similar thermal signature to a human body, so a FLIR camera shouldn't be able to pinpoint a grow in theory. I thought about the 1250HO model, with it's larger LEDs, but I think it would be overkill for my small space and the cost was a little more daunting (if I still had my warehouse, I'd give em a run for sure).
I'm also using herb.IQ for plant/data tracking and will upload the end results when i'm done with this first run. http://herbiq.net/
The lowdown: http://stealthgrow.com/index.htm
(marketing copy/paste from their site)

- Spectrum of Light - 455-475nm, 620-630nm, 660nm
and bright white
- Optimal Area of Coverage – 3' x 3'
- Lifespan – 50,000-100,000 hours
- Dimensions – 13" x 19" x 4"

|The SG 602 is now 25% brighter! It has proven to produce comparable yields and distinctly better quality than a 1000watt HPS bulb. The SG 602 has long been Stealth Grow's bread-and-butter product. Start seeing improved results with the SG 602 today!
Veg: 4bulb T5 set up vertically in a 2.5' x 2.5' space.

Flowering: SG602 LED in a 2.5' x 6.5' space.
for this grow, i'll be growing out one of my favorite strains. my cut of Durban Poison is ... unique .... she has a terpine profile that will knock your socks off and she has an aphrodisiac quality to her as well. I have yet to find a better Durban anywhere. Yields are very good and I have a lot of data on the backend to compare. I will also be running a few Durban feminized that I made and a couple AK47s.
I found a couple youtube vids they did as well, informative and interesting: http://www.youtube.com/watch?v=0KIIk33s2qs http://www.youtube.com/watch?v=QcJDB...eature=related
the penetration levels I find very interesting and look forward to seeing how the lower buds compare to the upper canopy. again, I know the durban very well and will be able to see the differences.
so ... I recieved my SG602 on 2/24. Packaging was done very well, packed with a few inches of styrobeans around each side. comes packaged with a manual, power cord, wire hangers for the 4 corner posts and 4 quick clips (IMO, these should be beefed up a little - the hook on the wires seems like it could bend out, not a good possible scenario. I swapped them out with real closed-loop steel connectors.)

my initial plan was to test the 602 against an HID for direct comparisons, but I found the heat loads to be WAY to much for my equip to handle. so i'm going to just run em under the 602 LED and compare yield/grow data from my HID runs.
these are initial veg growth pics (1000w HID 1st pic. within days of the other pic). from my reading and talking to SG, transitioning from an HID to LED will take a few days to a week for the plants to adjust and start showing normal growth/vigor. I can certainly say they are very happy with the spectrum and growth has been comparable to an HID easily.

these are timelined, so you get an idea of growth.

The room was flipped to 12/12 last week, so the game begins!!

Awesome, glad to see the stealth grow in use. Always wondered how theyd do. Might just be me, but none of the pics came through?
All medicine in each of my posts is grown in full compliance with the State of California's Compassionate Use Act of 1996.
Double check your uploaded pics, they won't open here.
Nice one, best of luck.
One suggestion about lower temps, you should add some more light instead of using a heater.
You could use maybe 4 energy saving 35w halogen (they stand for 50w), that route you'd get some far reds to add to your spectrum.
Or 2, 4 cfl's ... neutral or warm white ...... or some selfballast screw induction lights.. something like 40w each
or a mix of the above so you can decide what works better.
Anyway that's just a suggestion, interested in what happens with your sg602 (never seen a journal I think)
growth has been averaging @ 3/4" per day vertically, but the bushing is much more. I'm very happy so far with the growth patterns and colors. i'll let the pic updates say the rest
what's your temperatures in there?
during lights on, temps are 81deg max during lights on (nite time on cycle from 8pm to 8am. outside temps as low as 30's at nite, averaging 50s now).
i'll be installing a light rail tomorrow, should optimize the space beautifully
Being an LED grower and being in the same city; Think Ill follow along
