So you havnt even really used one fully yet? And you go exactly on what you're told...*facepalm* So you don't have any yield figures or anything to do a comparison? Intact noone has offered any sort of yield figures,it'd really help the discussion. Also anything for the supposed improved "quality".
Hortilux and most other bulb manufacturers DO actually offer all the statistics you could ever need,and at least they're bulbs are within 10% of their claimed output.
What reason has a company to hide the performance tested figures of their products? There's really only one reason why ANY company would do that.
Anyways,let's stop the arguing,instead you guys hit me with yield figures and if possible your setup? Let's stop talking "Internet" facts and start talking real world facts.
Let me start:
My last grow was 400w HPS,I got 209grms dry for a total electricity cost of no more than €90 ($120)
EDIT...and admittedly it was with bad nutes and a few facepalm moments courtesy of myself (as we all do!).Ill post back results for this round when it's dry,it'll be a 600w HPS,more accurate for some of the figures mentioned earlier.
I won't judge your problems in your last grow as we all have them, I have had my fair share of them. I have completed a grow under the LED so take your slap back, the internet is a great hiding place my friend. I don't know how you derive at what you think you read, it boggles me. Anyway here are my results so far, laid bare. No trickery just honesty.

Here is a link to my grow thread where I put 20x greenomatics from seed under the LED panel 550W in hugo blocks...6x6inch rockwool 1ST MISTAKE....which I decided to water by hand 2ND MISTAKE.
18 survived, one was a mutant that never took off and the other a hermie/male/mutant. GHSC never offered a replacement but said it was par for the course. I had the light over them on a 18/6 at 18 inches above canopy for the first 3 weeks. Then once flowering started I upped the light to 20/4 still keeping 18 inches from canopy.
2 weeks after this run I planted another run of 20x greenomatics, they spent about a week in riot cubes under the LED to the side then planted in soil in 1ltr air pots, I got them free so tried them. For the next few weeks they were under the LED and did very well so much so that I wanted to use the soil/airpot again but in a bigger size. Once the soil run got too crowded I put them under the 600HPS flip flopping them between rooms 12 on then 12 on again for about the next 3 weeks or so. They are now this week finishing under 18/6 600HPS.

The LED plants yields and performance was dismal as I openly state and recognise in my thread, I lay this down to the rockwool which the plants never seemed to like and my lax approach to watering them, they probably could have been wetter from the start. All in all from 17 plants so far...one is still not finished and is under the 600 now I got a paltry 2.14 ounces of weed. Some were harvested early and others later but the total is 2.14oz.
The total weight of the HPS mostly flowered girls are yet to be harvested obviously but will easily reach around 9-10oz. They have had their restrictions too, the pots were just too small so overall restricting the plant, yellowing leaves at week 5-6 onwards scream that. It was not nute deficiencies either. I would conclude that the experiment were not quite strict on criteria.
A more accurate and fair comparison would be 16 each in tent in larger 6ltr air pots.
I think it is also fair to assume that because of the level of poor result under the LED it is more down to grower/medium error rather than the panel, I think we all know she is capable of much more.
I will be documenting in the LED thread a continuation under the panel of 6 plants in soil which I will start soon and try to keep the panel at 24 inches to see what the outcome is.
EDIT: As for companies witholding info....well that is an assumption really, nobody knows their reasons now and it is unfair to assume it is all negative because the seed was planted by the chinese claims in the past. Consider that it is still an area that is still being developed and the players all still fighting for technological advancement as well as market share. I wouldn't want valuable info to get into the competitions hands, would you? Also consider that whoever gets it right will be the leader in a market that will eventually faze out HID and flouro (for grow obviously..)
I should also add as a benchmark that under the 600's in a 4x4 space I never get more than 550g dry and usually around the 450 mark. this is 16 cloned plants vegged for 2 weeks then into flower at 8 weeks. strain is medi bud which in its add is a huge yielder, my thinking is the light is the weak link, not the strain. I use dutch poots with digi ballast which is heat factor 999 hence why LED sounds nice...
PS. The images I think will speak for themselves with regards to resin production, if their is one thing that is undisputable by anyone who has used LED and HID, the resin is unmatched and I stand by it.
i salute your honesty man hopefully next run will work out better im sure it will watering problems are very common in led grows thats why i went deep water culture very simple/cheap setup and i just water as my plants eat it up i love it.
