sorry if it's already been discussed but how is the penetration w these? wondering if they'd do as well in a tent set up w more headroom or if this is a more effficient setting for them. either way very convincing grow show lap,

I'd probably go with as many of these as I can comfortably fit in the case you have - https://www.digikey.com/product-det...uctor-inc/SI-B8U05128HUS/1510-1585-ND/6149750
Or even the 2 foot strips if they fit. I'm not sure if any reputable alibaba guys would send you smaller quantities of the ones on adhesive strips but it wouldnt hurt to ask. Samsung LM561C is the diode you want. I'm pretty sure their top bin is S6. Figure out all that and then figure out how you want to wire it and then pick your driver. If you havent been to https://www.ledgardener.com yet, you should spend some time there. TONS of info.

Hey FAM! My first run with these, I had them VERY close to the tops, like .5 inch away for some, 2 inches or so away for most. The GG4 handled it pretty well, no bleaching or burning, but the Chem 91 really didnt like it. I had very little larfy popcorn bud and I was rather sloppy with the upkeep of shit down below. I had several stacked colas 10 inches or so or more and the buds were solid all the way down.
I purposely left a lot of under growth on to see how penetration would be. I was impressed.
Next run I think I'll aim to keep the lights about 4 or 5 inches away from the plants and I think they'll be a little happier. I hope that answers your question.

My LED plan is to use shelves for multiple canopies. I'm thinking I can get three or maybe even four canopies under a regular residential ceiling, SOG or little ScrOGs. You could for sure get two canopies in a tent if you wanted to go that route.
Hey Lapides (and everybody) check this shit out, its pretty interesting: https://academic.oup.com/pcp/article/39/10/1020/1844911/Green-Light-Drives-CO2-Fixation-Deep-within
Show that to anybody doubting white light LEDs, the green part of the spectrum is useful, even better if you're running supplemental CO2.

I'm getting a 503 error accessing that link, unfortunately.
Keep trying, seems like a temporary error. Or you could google it or something the article name is "Green Light Drives CO2 Fixation Deep within Leaves."

Lap that little experiment of yours was nothing short of amazing. Thanks for sharing it with us. I concur with dislexus, this would be phenomenal for shelf/rack gardens. I'm thinking cloning and/or sog applications with aeroponics. I will be testing that theory soon as I wrap my head around the electrical portion of wiring and powering led strips. This is going to be fun!
Round 2. Same plants, Chem91 and GG4. Chem on the left this time. Almost a week since the flip. The tops of the plants are right at 2 feet from the floor. CO2 will be added in a couple days, a little late but money is kinda tight. Oh yeah, I knocked up my wife. We're expecting our first baby in May.
Anyway, here's a shot a took tonight -

Lap!!!
Been way too long old buddy.
Congrats on the baby!!! Amazing news! I am expecting a son any day now. Babies!
You have got my wheels turning! I have been sceptical on LED but obviously trust your opinion.
Going to fuck around with these for sure I will keep you posted!
Any difference in actual head?

Yooo dude, good seeing you post! I hope you're doing well and congrats on your baby!
I'm not sure what you mean by actual head. If you mean like stoniness, not at all. I chopped the glue last run a whole week earlier than what I normally do. Usually just a couple days early for me would give that weed a little paranoid edge. None whatsoever this run chopped at like 60 days, I usually run it 68ish.
13 days in. Shit moves pretty quickly. I added CO2 a few days ago, CO3 and CO4 getting added this week.
congrats on the bun in the oven. parenthood is a trip! make sure you get this box as dialed and automated as possible before may :wink:
Can't wait to see what the CO4 does for you. Been hearing good things.

Wow, really red! I've heard purple petioles are common with LED, but red?
Red, purple, snazzberry, shit is lookin good regardless!
