NOT "american" enough
Those were the early days when we were trying to wrap our head around PAR spectrums from different light sources and the fact that we were seeing comparable yields despite having a PPFD that was half that of HPS. I felt the backslash for the ill-conceived term, "LumiPAR," so I pulled the concept from our collateral soon after. Yes, it was confusing and the BS radars rippled through the forums; seems the damage was significant. Mea culpa.Is their a reason why we don't recommend LG since the release of these?.......was it always just about them pissing us off over the BS par#s and not mostly "white" power ??............I don't remember what went down anymore
Can you clarify on how close the yields where?? @ half the ppfdThose were the early days when we were trying to wrap our head around PAR spectrums from different light sources and the fact that we were seeing comparable yields despite having a PPFD that was half that of HPS.

I just posted a thread about the photosynthetic rates of HPS vs LG LEDs for Gerbera. As it turns out we weren't too far off from our estimate on effective PPFD for our LED spectrum; a small consolation.
About those LG Pro OSRAM diodes; yes, they're top-bin. Just in the last year, the diodes' efficiencies coming off the line have improved. The Pro 650 and Pro 325 are now running at 615w and 310w respectively; the high-voltage units are even better at 285w and 538w respectively (edit: although this is because of the power supply, not the diodes). Now I have a problem of a product name that doesn't match the wattage pull; another lesson learned.
We were growing cherry tomatoes, chrysanthemums, lettuces and herbs under ES330s. The science supported the idea that a plant specific spectrum using narrow-banded LEDs would have a higher efficacy than an HPS spectrum. In our side by side comparisons with HPS, even when the LED output was less than half the PPFD than that of the HPS, the yields were comparable. The studies can be requested here. We're still investigating the phenomena (hence the gerbera post).Can you clarify on how close the yields where?? @ half the ppfd
I'm adding this to the product marketing feature queue. We build 'em as fast as we sell 'em, so if you buy one today, there's a 90% chance it's a new piece off the line. Unless of course you buy used. Manufacturing has been asked to track diodes and serial numbers moving forward.Is their a way for the growers to know that they're getting the latest/most efficient LG units when purchasing?? model/sku # on the casing??
Agreed, that is a misleading statement. The proper statement that we use is...I would also try to remove " par #'s equal to 2 1000w hps" from your product description ........it's misleading(in terms of yield) to the average consumer IMO
damn close, manThe Pro 325 provides red and blue PAR equivalent to that of a 1000 Watt HID light while it reduces energy consumption by a whopping 70%.

the Oslon in the BML fixture must be super top bins...About those LG Pro OSRAM diodes; yes, they're top-bin. Just in the last year, the diodes' efficiencies coming off the line have improved.
These probably do not dissipate 10W, more likely 6 or 7 watts, but they are set up nice for beaming the light into the canopy.I've asked a few times for suggestions, and while I would love to follow up with those and order a nice led unit from a reputable company, my funds are all but tied right now.
What i do have, is a $50 amazon credit, and i have been browsing various led bulbs/fixtures that are available on that site.
Can you send me some suggestions on what a good investment would be for $50 with little or no added from my pocket, just for now until I have the resources available again for a nice led unit.
Thank you
Cool or neutral white for vegging phase and warm white for flowering phase. To some extent it depends of whether you are growing a sativa dom or indica dom. The indicas seem to benefit from a longer veg period and might benefit from more stretch (using more warm white)Also, if i were to get led bulbs, which spectrum? Should i go specific for vegetation and flower like with cfls, or just go for daylight spectrum?
Hope all is well Psuagro, did you happen to catch my latest time lapse with the Hated HydroGrow LEDS? lol... I didn't do as well as anticipated. didn't reach my gram per watt that I did with the extreme series..but hey 397 grams aint bad for just two plants.....Can you clarify on how close the yields where?? @ half the ppfd
Yeah I remember how excited we all where when the #s released for the proline, then guod "straightened out" our math
Good to hear about the chips all being top-bin now, Is their a way for the growers to know that their getting the latest/most efficient LG units when purchasing?? model/sku # on the casing??

good luck
That's fugly!,I can do a buck forty in both and that's my limit but one has way more class..... literally looks like the skateboard I bought at toys r us in the eighties.......lolDepends...

Nice.......keep doing what your doing broHope all is well Psuagro, did you happen to catch my latest time lapse with the Hated HydroGrow LEDS? lol...

sounds like the best option. using a bunch of 3 watt diodes spread over a large area.just need to find a large aluminum sheet to keep them cool. thank youOkay..makes sense now. If it's one of those affordable ebay multichips I would just switch it for a few smaller ones and spread the light out
