Isn't thaf insane overkill. about 90w per sq. ft?

Dont harvest early because of the discoluration, you might lose a few sugar leaves but the buds should be fine.

If this is really the start of a business venture, you should forget about COBs or LEDs for now. What the big (possibly only) downside to LED vs HPS? Initial capital requirements. Thats your main problem right now yeah? You'll be waiting a long time to make money growing in a bucket adding one...

Actually I didn't notice the 'HPS' cob. Thats pretty cool. Is that thew first time a one of the big makers marketed a cob for horticulture?

So boners all round for the light nerds but the rest of can carry on.

Anything worth cob buyers hold offing decisions over?

Ah, thats what the "C" was. No that sounds perfect, eacy cob would be pulling about 50watts. 7 cobs run super soft in a 15" square fixture isn't something you'd design from scratch but it seems worth doing. It should excellent efficiency even if the drivers are probably poor? What do you think...

Could I run 2 cobs off each driver? .7a * 36v = roughly 25w. That would give me a 15 " square fixture with 14 cobs drawing around 350wats. Would that be dumb?

They;re from a Mars II 900 ( 400 draw), 7 in total in the fixture. One has 2 outputs, one used for a pc fan , the other goes to the diodes panel. The other has a single output which goes to the diodes. Whats the best "most efficient" cobs or premade strips I can run off these?

Either of those would start a munchies death spiral.

Is this a pricing error or am i missing something. A 3590 and all the fixin's for < 10 bucks? http://www.cutter.com.au/proddetail.php?prod=cut2890 9.25 USD 8.29 EUR 7.14 GBP Kit List of parts Part Quantity CXB3590-0000-000R0HCD35G COB 3500K 72 Volt 50-2303CR Ideal Holder to suit 50-2300AN...

I have 7 drivers, 6 for the panel, 1 for the fans I guess. Out : DC 55v - 88v ( .73 - .745A) Edit: sizewise its 15" square. so 2 panels would fit it nicely. I'm guessing these drivers are no good though.

I have a Mar 900, which draws about 420 if I remember correctly. It has a veg /flower switch witch I presumme just turn on two drivers. So I have an epi panenel with two 200 watt drivers, I could I use just one of those drivers maybe? edit: screw it. I'm going to open open the mars and see...

Are these boards an easier way to upgrade an epi-panel ( Mars etc) than cobs? Edit: for someone doing their first diy light project for example

Theres a bunch of diodes surrounding each cob.

What does it do?

Every body goes from Cheap Epi- panels to cobs. Nobody goes the other way, ever.

I'm totally guessing, but about two weeks maybe? How long after you went 12/12 did you see flowers? The bright green leaves and straight white pistols makes it look like its in "mid-flower" rather than late bloom.

Looks lovely, but not near ready.

Why not go with a 90cri, you'll get the same proportion of blue but your red peak will be in a nicer spot. You have an abudance of light so the slight lose in lm/w wont be an issue. btw, I recently vegged and flowered under citi 3500k 90cri and there was no stretching at all.
