Really tell me more!, what is the cost? Im using sunshine mix4 with the recipe for success kit, I have two bubbleponics kits, I wish i didnt buy, thinking about selling on ebay. I have not really used them because they seem like the plants would be to crowed and once the plants were big water change outs would be a bitch, im thinking about the Flo & gro but i like the ease of soil but im tired of the dirt and having to dig holes in my yard to dispose of the plant waste,

reptile bulbs are the only source of true UVA - UVB (LED UV lack the proper one, I think is the UVB).
Having said that, people are still experimenting about increase resin production.. some people swear by them though.
Others, like knna for es, says that the increase of resin production is archieved by the royal blues so there is no real need of UVA-UVB.
I'd like to hear from people with tangible experience/experiments

maxpesh understanding is, in my view spot on, about the useless UV diodes employed in LED lights; what is very much arguable is his general idea about UVA-UVB and plants (sourced by not led lights)

Man, don't order from hydro grow. I ordered from them and the unit was backordered (I had to call to find out after 5 days). They said 4 weeks until I have it. I cancelled and they charged me a $120 restocking fee even though it isn't in stock. Al they could do was say sorry. Those guys suck and do shitty business. Just a heads up! :(

i would like to see a grow with UVB and without UVB to see the difference....because i have a blackstar and it definitely has definitely produced a lot of resin but i don't know what it's attributed to....the light or the genetics

I've seen amazing CMH grows and its positives definitely out-way the negatives...........
Was it meant for horticulture? No but philips is coming out with their new "elite" cmh bulbs for plants and paired with "Cycloptics technologies" fixture coming in at 1.95 PPF/W @ 318 watts. The 550watt model releasing next march is pushing over 2.0 PPF/W!!!!(easily beating the king (gavita pro 1000w 400volt (@1.85 ppf/w) and all led fixtures on the market as of now IMO).
Thanks to my friends at another forum and my professors at the school for confirming this info........
Its called "all bright" and is funded by the US AG Dept. (Grant), so NO cmh bulbs aren't dead; far from it....

Anyways I still believe that leds are a viable grow lighting alternative for non-commercial use like myself........be safe WeJuana and happy growing.

I personally have had nothing but great experiences with Grow LED Hydro and their customer service. Furthermore, their product works and works well. Not to dismiss you story, but my experience has been great,

Just saying that my Philips greenpower was by far the best yield/quality that I had compared to all other HID's. I hope that LED's are good for more than just personal grows though. I hope that we are looking for alternative to HID for all grows including commercial, otherwise, what's the point ? Tell you what though, I just had a look at the specs of that Philips Elite Agro,,,looks promising :-)

P.S. just had another thought ;-) Out of all the led companies and the minefields of info, and the arguments of what works and what doesn't work, I think I would be inclined to believe the LED R&D of Philips as they've been in the horticultural lighting industry for a lot longer than anyone else with many resources around the world, just saying !

He's not talking about GLH. He was refering to HGL or Hydro Grow LED, the company ran by cammie, who has been scamming people for a while.
