Show me your drying set ups

a DE 1000
A what ? Sorry, I'm foreign and not that into the english grower jargon already.
With equal penetration in a 4x4
Use a panel with 9 cobs so you have a cluster of 3x3 cobs. If you run them on 1 ampere (lots of drivers out there adjustable from 0,525 amps to 1,05 amps) they will outperform a 600w bulb. When Cree CXB 3590 are run at this ampere they produce the double amount of light as a metal halide etc. The effficiency is 65% to 70%, that means 100w flowing into a cob panel will produce 65-70watt of light and 30-35% of heat
what happens when one diode burns up
You unplug the cables from the socket of that particular cob, remove two screws and install a new cob. It's really simple and comfortable ;)

Those Cree CXB 3590 are dirt cheap by now, the whole panel would cost you around 500 bucks (rough estimate). It would deliver the performance you need for a 4x4 and it would even outperform a 600 watt hps, resulting in a higher photone output and a increased yield.

I wouldn't bother so much about if there are new/better cobs being developed. The CXB 3590 need half or even less the wattage to produce the same amount of photons as a hps. In my opinion that's a milestone and I'm totally satisfied with my panel. It has more benefits than saving energy. The buds smell better, you don't have to struggle with heat during summer and you can finally take growroom pictures without the light fucking up the picture.

I got a vipar for veg its meh had i known how easy the diy was i woulda gone that route for my veg and i still might

The vipar covers my little area ok and is doing well enough for the price

But i think strips would work better but i havent tried them personally either
It's recommended to use both spectrums for veg, just the blue makes for really short plants like stupid short. And is a bit lacking both spectrums work better not just for flower but veg too

Sorry to kill your mood, but those panels are just fancy and overpriced scrap metal of tomorrow. There is no way that these monocoloured leds outperform a cob. Cobs don't even need this shitty mixing of colours, they provide a full spectrum like a hps.

Yes

Edit: Don't wanna spam this thread with led stuff. Send me a message or visit my grow journal, I'm happy to give advice if possible.
? Its my thread :)
Spam it up i dont care as long as its not stupid shit.

im down to brush up on my led knowledge

Look up viparspectra they ain't mono, differing colors within the spectrum not like the old leds that were straight red and blue

5W Epiled/Bridgelux are still crap, now matter how efficient you run them. Even if they weren't: The light distribution is still shitty, because the leds don't have reflectors. It's just overpriced garbage from china.

THIS is led power (~190watt / 47,5 watt each):

Whats a good cob build that will max out at 1000w ,
how many cobs, what kind of price per cob
Doesnt have to be the cheapest but not the most expensive eother lol

DE = double ended
A Double ended 1000 will make a single ended 1000 look like a 600w
I’ll never buy another single ended HPS bulb again, the DEs work to well.
I haven’t seen any LEDs out yeild a HSP in a 4x4 yet.

Is this still hps/mh technology ? Because I've seen this crazy 315 watt cdm bulb you can purchase, it really comes close to the efficiency of the cobs.

I believe leds tend to have equivalent intensity but less spread and penetration (giggity) which is where hid picks up the slack, something along those lines
