LED and BUD QUALITY

[exoticrobotic]

In 2002 I grew out a Spice of Life Adventure Mix, which was Breeder Steve's Sweet Tooth #3 garden pollinated with all his male breeding stock (Shishkeberry, Blue Domino, Big Treat, California Dream, Tropical Treat, Jack Herer, Ortega, Strawberry, M39).

Of course, I had no idea WTF I was growing, but there was one truly standout female in the pack that was so thick and resinous and STINKY that I nick-named it "Mr Diesel" – because it smelled exactly like diesel fuel. And this was before I'd even heard of NYCD.

Despite calling her "Mr" Diesel – or maybe because of it – she was strong as fuck. I gave some to a Canadian friend of mine at the time, who was obviously familiar with Canadian genetics, and then one afternoon I got a call from him:

"Dude, I'm parked on the side of the road in a country park with my wife. We were stupid. We smoked some of your Mr Diesel in the car before driving home and after 10 minutes I had to pull over. I can't drive anywhere. I'm SO FUCKING STONED! How long does this shit last?"

I laughed, but it was kinda serious because they were stranded in the country and neither of them could drive until the effects wore off. Apparently they spent well over an hour trying to come down enough to get home.

Ha! I also grew out one of Breeder Steve's adventure mix. Thanks for the info on the males used as i still have a couple of packs from freebies GN sent out a while ago.

The one i grew was Grapefruity and fuely. mostly Grapefruity but quite strong.

Not strong stop me driving strong, like wtf are the lights, oops thats the wipers, omg the indicators are alternating now and who the fck has just pulled up behind me. shit i'm gonna have to stash it quickly somehwere safer but plenty strong enough.

I cobbed some of it and then gave myself a whitey smoking it- first in 25 years.

I did the same.. I found a few in his Adventure mix I liked. I used one with GG#4. I still have some Deluxe SWT #3 f2... These are in my to grow bin. When I saw these posts must have been divine Intuition lol.

see how much fun a thread can be when everyone plays nice! this is now the LED and Bud Quality Club!

Well . . . there's nothing wrong with a bit of spirited debate. It doesn't have to be personal. But I don't think we need to be too precious either. We're here to challenge a few conventional wisdoms, after all

so, Whitaker Blues is one of JD's and one of the genetics involved in the Blue Star OG. Josh of BlueStarSeedco collaborates with both DJ and JD.

i'm also known as Delta9nxs, and the PPK device is my creation. i was living in Eugene, Or from 2013 to 2018 to hone my skills in a legal, competitive environment. Josh is a user of my system and while he was visiting Oregon to see the Shorts he came by and toured my facility and came to the house for a while. we talked about all kinds of stuff but i was very impressed with Josh as a breeder and a human being. he is one of the most dedicated and caring people in the industry. you should check out his inventory at BlueStarSeedco.

i grew Sweet Tooth #4 for 7 years with no mothers, just cloning off the ones going to flower. another great plant. nice to know Breeder Steve is still active.

i feel for you living in an illegal environment. before Oregon, i was a black market grower living in several southern states that still had medieval laws. life in prison for a joint.

but the same uptight assholes who used hypocritical moral arguments against cannabis now see the money on the wall and are legalizing these states one at a time. amazing how greed can change your morals.

i have found your comment on "the fade" to be mostly true and normally my plants are lush and green right up to harvest but i'm also experimenting with the application of stress at certain points and this time i drained the solution and refilled with plain Ph corrected water for the last 10 days. next time i will run this plant without the "flush" just to see if there is any difference. you can't flush nutrients out of a plant but you can force them to use up the stored nutrients. jury is still out.

i'm enjoying the musical additions to this thread. i listen to almost anything but love blues and jazz. i lived in San Francisco from 1966 to 1971 and went to most of the Fillmore concerts. i saw all the old delta blues greats and the British invasion bands. i was at the "Cream Live at the Fillmore" album concert. the night Ginger Baker went ballistic with the famous 22-minute drum solo. Clapton and Bruce declared a break and walked off the stage but Ginger Baker stayed.

i saw Hendrix at the October '68 Winterland concert, he played 3 nights but i got lucky and was there the night he set fire to his guitar. pot was still illegal then but i remember the thick blue haze that hung in the air the entire concert.

the last few years i've been listening to the human voice a lot. so many talented vocalists. i've been listening to this lady quite a bit lately. her name is Violet Orlandi. she's from Brazil but lives in the US now.

she likes metal and dark music.



here she is doing some Disturbed.

You've piqued my interest in PPK, but I need some time to have a read.

But Hendrix in Winterland . . . maaan!!!

oh no, you're such a meanie! you've burst my little bubble of happiness!

For people saying not enough heat , with led
quick fix is electric blankets on the floor thick waterproof sheeting over ,
Plant on top in trays
Boom , no more probs , super cheap to run

 

[Rastafarout]

Some f3 Sensi (derg corra) star under board leds dimmed to 200w wk 8/9

The quicker one nearly ready

This one still a way to go , both smell similar the second one super greasy
First run. I’m looking forward to
Next round if they pass.

here's a link to the thread i did in Oregon. lots of tech and pics. it was my last effort with HPS.

Something wicked this way comes

this thread is intended to show the "state of the art" ppk plumbing. since i started on this journey more than seven years ago the basic operating principles have remained the same but we have all gone through many iterations of plumbing. most of these, i now realize, were derived from our...

www.icmag.com

the first thread i started in sept 2009 is the "Passive Plant Killer". although there was a lot of theory discussed there the build has greatly simplified since then and it's devoid of pictures.

here are a couple of pics of the 10k sq ft cbd warehouse i designed, built, and was the director of operations for in Nashville Tn for 3 years. my first large effort with LEDS.

this is a PPK room also. recirculating closed circuit soilless. extremely conservative on nutrients and water.

there were 10 rows like this in the flower room. 5 ft wide by 60 ft long producing an average of 30 lbs a week of finished flower. this strain is "Purple Mesa". it tested at 18% cbd.

I am a 1st time LED user. Without meters and by looking at your plants, how can can you tell if the power level is too intense or not high enough ? Thanks in advance !!!!

 

[Hammerhead]

Very different genetics performing very well using LED/CMH. There are more LED lights than CMH. I have more Haze Hybrids than anything else right now.

Too high: purpling stems and petioles, new growth is quite pale and doesnt seem to get dark green.

Borrowing photo from Far outs post above:

See that leaf in the bottom left corner with different pale green coloring and purple stem? Its a good example what im talking about, the rest of the plant looks very nice, not beating up on Far outs plant, its just the closest example.

 

[Rastafarout]

That’s a different plant …and 200w in a 1.2x600 is no way going to be to high if that’s what you saying? @Rocket Soul

i'm sorry to tell you that it is simply experience. i can look at a plant from across the room and tell you if is getting too much or too little light.

visual cues that a plant is getting the approximately correct amount of light;

plant is growing vigorously......slow growth could be too little light.

leaves standing out straight with a slight up angle addressing the light.....with too much light the plant goes into photoinhibition, the displays of which can include drooping leaves or leaves twisting the ends as if trying to reduce intercepted light. presenting the edge of the leaf to the light.

unusual coloration on stems but sometimes this is strain dependent.

if you can't afford a meter right now there are apps for phones like this one;

‎Photone - Grow Light Meter

‎Take the guesswork out of grow lighting! Measure PAR / PPFD, lux, fc, and kelvin: All within the most accurate light meter app out there. Setting up your plants' optimal lighting is not easy, if not impossible without a proper PAR / PPFD plant light meter. Calculating your indoor garden's...

apps.apple.com

i have one on my phone and i have a $375 Spectrum Lightscout. the phone apps are not nearly as accurate but are ok to use as a relative tool. by that, i mean if there is an error the error is repeatable and can still be used for comparison.

in research, everyone uses Licor gear but they start at around 1200 bucks and we are not doing peer-reviewed research.

both Apogee and Spectrum make good working-class meters. most of the other ones on the market are shit and not worth the money.

a meter is not something you will use every day unless you are operating a large room with a lot of lights.

you will use it to initially set your lights and then a few times during a grow to help you learn the distance you need to operate at.

a hand-held learning tool. once you know your lights you won't use it much.

be aware that a par meter is just giving you an instantaneous reading. how much the plant is getting at that exact moment. you want to focus more on total light per period, or the Daily LIght Integral.

to get that you multiply the reading x hours of exposure x 3600 and then divide by 1 million.

so 1000 umols x 12 hours x 3600 = 43.200000. rather than actually dividing by 1 million just mentally drop the zeros.

this gets you 43.2 mols per period.

the phone app will do this automatically but it will not be real accurate.

i hope this helps!

No offense meant. It has the look though. If its in the middle of your tent maybe switch it to the side.

 

[Rastafarout]

No offence taken , photos can be deceiving, it’s 2 in 1 tent . Peace

Granted, my 25 plus year old IBL of Northern Lights is genetically used to high light input, since it began life in a 2x5 closet lit by a 1kW MH bulb but I'm pretty positive I cannot give SouthEast Lights too much light... ever:

That's an SF4000, about 3 in away from the canopy. As long as I keep temp and humidity within reason and provide max ventilation across the leaf surface, light bleaching/leaf twisting is non-existent for me.

"Granted, my 25 plus year old IBL of Northern Lights is genetically used to high light input, since it began life in a 2x5 closet lit by a 1kW MH bulb but I'm pretty positive I cannot give SouthEast Lights too much light... ever:"

i think that's the best way to design LEDS lights. if you want 1000 umols at the canopy design a light that can't deliver more than that. at about 12 inches.

one of my experimental lights is capable of delivering 1500 umols at 30" when i have all 120 bulbs positions filled with the bulbs on 4" centers.

so i had to run them at 36" to get the desired level of 1200 umols. or remove every other bulb.

running a 1680 watt light that you have to back way off to get the right level is wasteful of electricity.

your second pic shows exactly what I was talking about when the plant is getting the right level of light.

the leaves are at attention angled slightly upward addressing the light. that's the posture you want.

Ah, Utah University – where they're not allowed to grow cannabis and have to do all their experiments on hemp/CBD varieties instead

This is perhaps left for a separate discussion but if you're going to make claims about UV and cannabinoids, you really need to be growing medicinal (high THC varietal) cannabis to begin with.
