About 1.4 gpw but honestly we should all be doing gram per kw/hr
About 1.4 gpw but honestly we should all be doing gram per kw/hrIf it does any justice I use a photontek sq300w in a 3.3by3.3 and got 487grams but if I put in all the same pheno that average of 3 plants yielded 66.6 if I filled it out with 9×3 gallon pots I'd get 599 ball park can anyone do me the gram per watt
What would it be in kwAbout 1.4 gpw but honestly we should all be doing gram per kw/hr
Under 2 gavita 1700e and still 8 more plants to pull down at that point. There are loads of examples all over many forums, IG and the likes of the garbage social media. Its hard to debate anymore… LED out produces HID by a huge margin gram per watt.
The thread in the linked is a total of about 6.5 lbs in a 4x8 from about 1200 watts of LED just over 1 HID.
Not many commercial guys that arent getting 3 lb per light under LED these days

Now i have some reading to do… but you realize that was a 1000w de HPS vs 600w LED. What was adjusted was the spectrums and ppfd… but was lacking a full spectrum LED at by first glance and skimming i did not see efficiency.Here is a pretty good study done by Mcgill Its a lot of info to go through but worth it

Not a single doubt on the quality or you ability as a grower… i think that has the largest bearing.View attachment 1259753View attachment 1259754View attachment 1259757View attachment 1259756
Thank you Aqua! You've always been very helpful!
I do have to question 6.5 there? Being I haven't weight a yield in years, it very well might be?
For a comparison, let me post a typical yield I'll get off a 600 w hps. I usually flower out the mother once I'm done with testing
a cultivar. To me my cultivar appears to have yielded in that ballpark? Key word "appears".
This is a 1 plant scrog yield off 1, 4x4 Botanicare table. I probably should weigh em going forward.
Again 1 plant under a single 600 hps using the cheapy $30 Ipower bulb lol
Excellent quality, and I'm fairly certain I hit over 2 with the 600 in a really inefficient XXXL air cooled hood?
Apologies for the poor photography,
I have some time before I'll be back on the commercial end (hopefully sooner than later) I'm keeping an open mind, as if I could double what I'm yielding now, hell yeah I'd make the switch.Now i have some reading to do… but you realize that was a 1000w de HPS vs 600w LED.

Great spectral info it looks like in there though.
Watt for watt just no way a HID can compare to LED. What does compare is the spectral makeup and that’s something being tweaked in LED and with tubable spectrums coming out LED will eventually be able to maximize all stages of growth
Thing is its a real learning curve on the switch… so much more than most anticipate and they get caught iff gaurd how much it changes the needs of environment and grow room conditions. The link @Dr.Green55 gave makes a stong argument to look at tuneable spectrum LEDs and the only one i see worth it right now is the synce LED brand. But that opens a whole gigantic cans of worms in other adjustments needing made.I have some time before I'll be back on the commercial end (hopefully sooner than later) I'm keeping an open mind, as if I could double what I'm yielding now, hell yeah I'd make the switch.
I am noticing more, and more commercial grows are going LED.
Agree fully. In fact that day is arriving and I believe can far surpass hid in every respectNow i have some reading to do… but you realize that was a 1000w de HPS vs 600w LED.

Yeah I try to stay away from the blueThat paper noted blue spectrum 400-500 had a higher thc content but lower yield.
So full spectrum blue leaning veg, full spectrum red leaning early mid flower and high blue mod red and low green finish… thats my thoughts but im not saying why lolSynce for tunable spectrum and it’s lens design, I think they have 3 or 5 year warranty.
I'd show you the phone app but not connected to my lights at the moment. Full tunability without loss of PPFD. Each channel has it's own driver and has Far Red and IR too. Way too fun my man.So full spectrum blue leaning veg, full spectrum red leaning early mid flower and high blue mod red and low green finish… thats my thoughts but im not saying why lol
Yeah im jealous lol.I'd show you the phone app but not connected to my lights at the moment. Full tunability without loss of PPFD. Each channel has it's own driver and has Far Red and IR too. Way too fun my man.
Yeah I saw one's like that al also but we're regular ceiling lights... Wonder about the output efficiently. Just as good as the lm301 or close???I'd show you the phone app but not connected to my lights at the moment. Full tunability without loss of PPFD.

On paper close. but I have not started my measurements yet, just got them installed.Yeah I saw one's like that al also but we're regular ceiling lights... Wonder about the output efficiently. Just as good as the lm301 or close???
