Lighting So many questions .

Right!

What'd I say...? ...just testing you, Yoz, ya gellie!

...nice gif finds mate! ...... How's the K-crispy gal doing now Yoz, did that finally halt and stabilize?

Seems to have stopped.
They still look manky, but it didn't get any worse, if that makes sense.
I cut back on the K rich base nute, which I deduced was the primary source.
Got a theory that the chelated Connoisseur range contributed to the issue, by facilitating faster uptake in extreme outdoor conditions.

Might be a pile of horse shit, as far as theory goes, but it sounds awesome!

Ummm ... Hate to be a pain, but I'm still hoping someone can answer the earlier question.

Specifically, how many COBs for a 2m x 3m tent? [6.7ft x 10ft]

There's so much amazing info in this sub-forum already, but my ignorance is scaring me with the bullshit numbers I seem to be coming up with!
For what it's worth, ideally I'd like to light up the room like a supernova to kill it with a 12+ plant grow, reaching for the sky in my 2.2m [7ft 2in] high, bad boy tent.

Simples.

Main priority is [obviously] to grow premium plants, but right up there on the priority list is to cut down the electricity bill from running 2400W of HPS, plus all the ventilation and cooling required to prevent the tent from becoming a microwave, with all the heat 4 x 600W HPS lights can generate - especially during summer months!

Sorry if I overlooked this. 25-30 cob watts per square foot is my recommendation for autos. Your space is close to 70sq' for us muricans. That's 1750-2100 wattts. Usually when people convert from hps to cobs they figure 60% of the hps wattage which is 1440 watts. You could also increase the wattage per cob as well. That will cut costs and labor.

Sooooooooo ...

~40 COBs @ 50W = 2000W total is a good number to shoot for.

Holy shit yoz 2000w of cobs would be the equivalent to about 4000w hps

OK ... So maybe my numbers are still a little awry.

Heres my little 200w cob light @Yozhik in my 2x3 and its insane bright.
