The big switch, HPS to LED

Damn thats a grow room. Great set up. I see no air ducting. That was another question i had was about heat
This is a 600 sq ft. grow room.. we have 1, 1265 CFM HyperFan intake, and a 14x24 exhaust. 2 ton Carrier Mini split A/C. It does a good job of keeping it ~70 degrees in the winter. We cannot run in Oklahoma during July or midway through August because it's just too hot here. But otherwise, we can run all other times... We need the break anyways. That's the only time we can go on vacation, etc. The HLG's are their own heat sink.. the whole top is a heat sink, and the MeanWell Drivers have their own heat sinks. Tops run ~105 and the diodes run ~ 128 degrees. I can't say that I wished I would have gone with another set of lights, except the new ones they have out right now with the red diodes you can use during flower. Great lights!, and very forgiving if you are too close. We average ~110 grams per plant dry and ready for market, or ~1.7 lbs wet for processors. This run we are doing dry because the outdoor crops have just hit the market, and processors bought all that shit cheap, and there is a ton of it out there right now. Our next run will be started soon, and be ready by April, so maybe we will go wet on the next run... IDK, we'll have to see.

when you start switching is when you start wishing... You Didnt Do IT. Feel like learning all over or sticking with time tested working products?
When you stop learning, you are just waiting to die. Every single person I know that switched to LED, would never go back to HID. Those are people I know in person. Not some rando forum people who could say whatever they want regardless if they've even tried or not.

well if you want reliable you have to go gavita or fluence nextgen and your looking at 1300 plus for a good led
and i just dont see the yield in the end 650 gavita vs 1000de gavita hps and the yield is better from the hps im sorry but it is

im sorry, but you sound very out of the loop with todays tech.

Yeah man id check out those de hps. There is a reason all the pros run them and not LED. I use hps and cobs but I'm saving up for a gavita

I tried/use led and they’re fine, my flowering room went back to hid pretty quickly....

I do use them as supplemental light all over the place and over clones/seedlings/moms. But all my main light for flower is hid, whether de hps or cmh. I have one space with a 315 cmh with 4x150 watt 4000k supplemental leds. However, In my main/big space I’m running de hps and cmh combo. No leds in there at all. And I have a pile of quantum boards/cob lights sitting around, de and cmh combo sort of kills it. There aren’t a whole lot of lights that put out as much par as a 1k de. Leds are cool....but not that cool...yet. I think most hardcore led guys here went straight to led. Or moved from flouros/low power hid(400 or less). Contrarily, I think most the guys that hate on leds, tried blurples or the panels that claim 10x watts they actually draw.

Both lighting types work and have benefits and drawbacks. Use whatever works for you, it’s not better or worse than what works best for someone else in their situation/environment.

I can respect that. But I must ask, how lo g ago did you buy your LEDs? What ones? It's only been the last year where LEDs have actually gotten good. Chances are you have tried leds that arent as good as today's.

What's a pro? I dont use them.. I also know many other "pros" who use LED, less and less "pro" growers are using HID. As I've stated before, cobs are not a good led to use. At the distance you need to maintain high ppfd, the beam is way too narrow and way too focused. You cant get very close to them, they heat up more than smd LEDs, and they are nowhere near as good as the current led standard (lm301b or lm301h).

I have cree3590(?) maybe second gen lights, quantum boards from hlg, a couple of very birds, and a couple green house lights similar to the qbs but waterproof. I’m currently running high bay smds, they’re similar to the Samsung diodes but cheaper, put out about 130 lumens/watt but they’re like 91cri. I dont think the quality of the leds is the issue. I just want more out of my lights than efficiency as far as it goes and I have no bias so I use whatever gives the best results in my space.

I think a pro is short for the word professional. And professional is i think someone who gets paid at a said activity. So i this case maybe the guy meant someone who gets paid in the activity of gardening marijuanas.

Yep and the secrete is just using a 6x6 trellis I learned on the scrog section the other day if you use bigger squares you get a bigger yield...so there is that:)
Im sure many methods give larger yeilds but i aint got the veg time for that and at one point led growers were just getting plain silly with their grams per watt but not explaining the two month veg time :-)

Well since you know it all and your a "PRO" I guess there is no reason to try to help you . tootaloo

Yeah. This is why most people stay away from rollitup.lol. never fear, there are plenty of decent forums out there.. keep searching
