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) SG 602 Wattage 600 Watts; actual power draw 400 watts* 1.5 amps @ 220V; 3 amps @ 110V 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" Number of LEDs 270 LED Chip Power 2 and 3 Watt Hi-power LED Chips** [TABLE] [TR] [TD]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! [/TD] [/TR] [/TABLE] The rooms: 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. View attachment 2080459 Strains: 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=QcJDBjEP_6o&feature=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.) View attachment 2080508 View attachment 2080509 View attachment 2080510 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.
