Don't be scared Chuck, let's have ourselves a debate.

Because lazy ass stoner run companies don't push the envelope. Innovators do. DE tech is close to a decade old. Companies are hoping to get one last hoorah out of HID lighting before it's truly dead. Including the awful wholesale companies run by stoner idiots like Hydrofarm. How long did it...

You got it. Just remember [ V x A = W ].

I also assure you the tent didn't play much role when measured below 24".

You are probably absolutely right about that. It was the best I had to work with at the time before I assembled the whole array. I could get the light within 10" before canopy temps get warmer than I like, but it usually hangs out around 18" or so.

Just to clarify, if you want to have 76w total with that driver, you need to be looking at the CXB3590 36V. 72v x 1.05A = 76w each

Incorrect. (15x) Vero 29 3500k @ 1.4a 937 watts This chart is courtesy of Grower's House Review.

1. A gavita DE 1000 costs $450-500, not $800. How much were Gavita's when they were brand new? If you haven't noticed, COB LEDs aren't exactly in the mainstream cannabis scene....Yet. This is the very beginning to a new indoor lighting revolution. Not knocking Gavita's because I know they put...

I think he means 75w between the two chips... Approximately 37w each.

It would just be 4 as opposed to 2. But hey, we can agree to disagree right? I won't say that at all. I will say it makes growing good buds easy, due to fullness of the spectrum. But is by no means a secret sauce for dankness.

Have you ever seen what electronics look like on the inside of their pretty outer cover?? So if my light fixture was UL/ETL listed, had a pretty box wrapping around it and just had a removable ballast chord and a power knob (dimmer), [and I ask again], would there be a market for that kind of...

Haha so first it's show me an LED light that can perform just as well as Gavita (or better). Check. Done. Mission accomplished. Then it's show me light that performs better than Gavita, and looks really cool too. Not too big maybe pocket sized? Gotta have the aesthetics to grow dank...

I yielded more than most HID grows with my first run on these. Including DE. Over 3lb per 4.5' x 4.5'. And the quality is a great improvement as well. No worries Chuck. :hump:

Something along these lines.

Yes. That is what I'm referring to. Each 600w+ fixture would still cover 25-36 sq ft. The fixture itself would be about 12-14 sq ft. Imagine a ceiling full of evenly spaced high power LEDs. The canopy penetration is unequaled due to the multiple sources of light.

I just pulled 1.41 GPW off of a 3000w grow. Over 2.5 oz per sq ft. With COB LED. Ceilings are at 78". I could build you a fixture to beat your Gavita DE 1000w and would use between 600w-700w... But it would cost (retail) probably $1600-1800, to maintain that "profit margain". Actual cost...

Not to get in the middle of this, and for the sake of learning and clarification ... But it seems that everything posted about UV-B exposure lends to the idea that UV-B radiation affects the entire planet as a whole, with different levels of exposure depending on several variables. Instead of...

Not yet..........

I agree. I got my yields dialed in, now it's time to grow some fire!

Huge is a relative term, but these things got pretty darn big! Grown under Vero 29.
