lets talk yield, .5g to 2.5 grams per watt. how can we get there?

Iam all about lowering my electric bill every month if i knew i could get the same or greater yields than 8 Gavitas 6/750's...4 old school 1000's. And a pricey big ass mini split and commercial dehuey.

1200w vero 29
first run 3.1 pounds 1.2gpw (7 week veg)
second run 5.2 pounds 1.9gpw (10 week veg)
this third run we are expecting 6 pounds cause there are a lot longer colas. hopefully 2.3gpw... (12 week veg)

WTF??? Damn those are just silly numbers
I got to do this COB game. Its just stupid not to. Wow.

Those are some eyebrow raising numbers. I'd like to see more.

Very eye brow raising numbers. Currently sitting at between .85-9x using aircooled conventional 1ks in soilless mix. Changing things up this run, no aircooled, just big ass mini split, no glass and added co2.

By the next run i hope to be converted to tables using drippers in rockwool. I have been told by others that switching the conventionals to de lamps would give me a signifant boost, but i got 7ft cielings. Maybe 600 watt de lamps are an option?

Whats the cost on buying a premade cob led lighting system?

I'd say cost of top quality COB LED is about $100/sq ft retail, and a bit more than half that to DIY. I split the difference and paid about $60.

I thought numbers like that were impossible. Then I met someone who pulled 14oz from 300w of hoT5 and 18oz from 400w hps.

A big factor in yield is how you train your plants.

Holy cow ass bro...around 2500$ to cover a 5x5? Your telling me id be looking at about a 20k us dollar bill to convert completely?
Click to expand...
You could do well for half that. You might look at the Johnson Grow Light Maximizer, that would kick ass in a 5x5. Other options abound, just insist top bin Cree CXB3590 chips. Northern Grow Lights is another good option. Or Tasty LED.

Well i was going to give cob led a chance with at least swapping one lamp out, but after looking at a price tag of 1700 dollars for the one lamp..ill just continue on planning the swap to 600 watt nanolux de lamps.

Well, think of it as a long term investment. Returns include;
  • No bulb or reflector changes, ever
  • More efficient means less power, more buds
  • Much lower heat signature, leading to additional HVAC operation savings
  • Better spectrum gives product quality improvements. You can see it, smell it, taste it and feel it
  • More yield, depending on how it's deployed
With all these advantages, it will definitely pay for itself- sooner rather than later!

I have the 1215 watt nanolux DE, I just bought 750watts of cobs to see what the 2 did vs each other. If the quality is the same or better and the yield is same or better its worth switching in my book.

Maybe if the end product still had a market value of 3-400 a zip..but damn, not in this market.

Lower costs mean maintaining your profit margin, especially in an environment of falling prices. That's basic economics 101 brother, I recommend you take heed or LED growers will be making weed for less than your light bulbs can compete with from now on.

How do I know this? Because I'm on the front line of the agricultural lighting industry and the entire industry is busy right now, finding ways to get out of the business of selling light bulbs.

Looking at tasty leds, the T4-2100 series model...300 watts or so @a price tag of about 700 dollars. If i could get a 3x2 coverage area out of it??id be willing to give it a shot and compare the quality myself, after all im all for quality improvements more so than yield.

Build your own for cheaper. Timber grow lights and cutter electronics have diy packages that make building these things cake. Timber even has a lot of it prebuilt and the wires color coated.

You'll love it, I guarantee!

See for yourself; look at the last few pics of my thread, link in my signature line.

Thats a nice space covered for 225 watts, plants look great. Will it cover the same space in flower and still produce tight nugs?
Click to expand...
One reason those girls look so good is because they are getting bloom strength lighting in that space.

I'm already getting a gram per watt in bloom, with a long way to go before I can call it dialed in.

Just browsed through, and those prices seem more reasonable to me. Pretty sure i can handle wiring stuff, i am a certified A&P mechanic.
Click to expand...
A&P? What do you fix? I had a lil training in high school as a kid, it was a blast.

With those skills going for you, building COB LED lighting will be an exercise in wondering where the hard part is. Lots of great places to get top quality parts here on RIU. Just head over to the LED lighting section and start reading, it's what I did.

Me n you broseph are in the same boat. One room i gots gavita doubles...yields about 2 per on the 750 setting (flex 6/750's) and the other room with 4 single ended thouies i yields about the same per lamp. Depending on strain and how much gumption i got to manage that canopy. Sometimes i get real lazy on a run and it shows. Maybe only 25 zips when my ass gets goofy. Depends on 5he cut too. Sin City stuff gets real floppy and low yield by nature. Damn the nutrient brands...with a dialed setup..with sealed room and co2...climate controlled dealy...canopy management is key and how much time iam willing to spend to get two plus a lamp.
