Quattro Kush: Day 50 of flower.

Check me out on Instagram if you're interested. Or DM. Correct, sir. Slight correction, my custom led design in a modified frame using China as my ODM.

SlurricaneXDreamQueen: Day 60 of flower. Slightly problematic grow, but always learning. Plus I don't think it would be as exciting if I didn't fear failure.

You mean the other plant that has a lot more purple leaves? I'm a bit lost Still watching that one, unsure whether I snipped all the nanners off in time.

Quattro Kush: Day 30 of flower.

Yo this winter humidity sucks! It's got me on high alert. Doing a lot of inspecting and preventative snipping.

Dqxslurri: Day 45 of flower. Quattro Kush: Day 19 of flower. (slightly earlier pic)

You can buy strong dual sided thermal adhesive tape. I've sourced some from Bidorbuy before.

I appreciate your kind words, brother. It makes me happy that we all share this passion for growing.

Quattro Kush: Day 13 of flower. Dqxslurri: Day 39 of flower.

Dqxslurri: Day 34 of flower. Quattro Kush: Day 8 of flower. Heavy defoliation.

Heck yea, it's super fun, brother :). We can enjoy it on behalf of others! Oef, 35 is no bueno. Maybe some super growers can manage that with co2 and extreme environmental control. But from what I've read, 30 is usually max optimal value. Man, you're too kind. I'm definitely no prophet figure, just a regular schmo with a passion. But I appreciate ya!!

Mighty kind of you sir :). I can go on a bit, it's true. Straight shooter huh, niccce. That's a preferred personality trait if you ask me. I have two, slightly different, older prototypes in my 60cm and 80cm. I prefer the slightly heavier red spectrum of 3000K over 3500K, however with the addition of 660nm the overall spectrum results in slightly less blue than is optimum, so I added just enough 5000K to get to about 13 percent blue, which keeps plants sufficiently compact. I follow the principle (sorry for the name drop) Dr Bruce Bugbee stated: As much red as possible, enough blue for dense, compact growth, and fill the rest with green. This may not be a popular opinion, but: Personally I don't worry about different lights for different stages of growth. I only care about a balanced, full spectrum light, that is a pleasure to use and then spend the rest of my energy trying to maintain optimal temp and humidity, VPD, DLI, training, and an effective watering schedule. I feel that by spreading my effort equally, it results in a far better grow at all stages rather than chasing a customised-for-growth-stage approach. There was a lot of trial and error trying to understand how to change the led layout, believe me! The specific driver you need for a 660nm strip(s) depends on the electrical requirements of the PCBs you source, eg. Forward voltage and current etc. It's might just be that buying a locally stocked Mean Well is cheaper than importing a Moso or Inventronics etc. Honestly, if your overall spectrum is already 3500k/3000k, I don't think you're missing anything substantial that will be a magic bullet. But.. new gadgets are fun :).

Pleasantly surprised, that one was struggling for a while sheesh! Seems to be staging a bit of a comeback.

Quattro Kush: Flipped to 12/12

Well thanks dude! Mighty kind words for sure! Awesome, glad you've got the led bug too! I guess I'm just a bit hesitant to go waving my 2c around. Yea dude, I love all the lights, love diy, all of it. So with that in mind, here it is: My light: 240W, Samsung LM301B SK bin 3000K+5000K, Osram Oslon SSL 660nm, designed for 60-70-80-90cm(max) tents. 92% efficient Fahold driver, PF 0.983. Foldable, driver on bars or external (2m extension cord), 3 year warranty. etc. (see the website for more) Maybe controversial, but from what I've studied, LM301B sk is the exact same chip as LM301H sk, LM301B sl is the same as LM301H sl. SL is roughly 5% more efficient for a 40% price increase. https://cre.science/en/lm301h-vs-lm301b/ Info on the upcoming LM301H Evo: https://cre.science/en/lm301h-evo-new-horticulture-leds/ Samsung LM301H SL is right up there with the most efficient, if not the most efficient by a smallish margin. I'm unsure whether Nichia, Seoul, Philips Lumiled, Sanan (what the Lumii series uses iirc), Epistar etc. have any new products out, accurate data is hard to find, so it's entirely possible a few have chips that come super close. They all produce quality chips though. Bridgelux is no different, the top bin gen3 chips in the best EB series strips are really good (slightly more ePar production, if that's your thing, but that's a deep rabbit hole). To match the output of the top bin LM301 chips, Mars Hydro (FC3000 vs FCE3000 and now Spider Farmer with their G1000 model) use around 32% more Bridgelux diodes, making them run cooler and more efficiently. Samsung and Mean Well established their brands first, commonly referred to as somewhat of a "gold standard" in the market. They enjoy those word of mouth bonus points. But, as with led chips, there are plenty of similar quality drivers, all with at least 5 year warranties etc. (Not that it translates through each brand's light warranty). In fact, Mean Well has been a bit slow to jump on the programmable driver train iirc. Oh, I'm not using strips, it's a custom layout I designed. I've been developing it with a Chinese ODM for a year+. I really appreciate your friendliness btw, makes a dude feel good ya know. Feel free to ask away. I live for this stuff.

I didn't know If I'd be breaking forum rules or just irritating everyone by posting off-topic. But ye, it's the first shipment of my lights that I'm currently making par charts for. Having to take a break after doing the 90cm x 90cm size, my lower back is so sore. @Prom is a super nice guy, he let me use his quantum sensor. Thanks again to you sir, tip of the hat!

Dqxslurri: Day 26 of flower. Quattro Kush: About ready to flip.

Quattro Kush: 18/6 (medium defoliation). Flip to flower soon.

Dqxslurri: Day 18 of flower.

Dqxslurri: Day 17 of flower. (Light defoliation) Quattro Kush: Still vegging 18/6.

Thanks dude :). It's super rewarding when it works out. Love training.

Dqxslurri: Day 14 of flower. (Defoliation, final cleanup)

Dqxslurri: Day 12 of flower. Quattro Kush: Still vegging 18/6. (Seems a bit healthier)

Dqxslurri: Day 8. Light defol, removed weaker, lower growth.
