Yeah mate that's correct 12 COBs in a 4x4 area...No this is my first run using the CXB's had some cheap crapping Chinese COBs before hand and they
didn't preform and were really expensive to run, 2 x 1200 COBs but not a recognized brand of chip! Got rid of them after the first run! Also had 2 300watt LEDs for veg
but flouro's were just as effective and cheaper to run.

Thanks for answering questions. Have you run hps out of those tents before with 2 1000 in each?

Thanks Tex.....not sure of the stain live in a country where this is illegal so a bit tricky getting designer strains and set up equipment, I got 7 feminized seeds from a friend
and grew them out and cloned the ones I liked the look of when the went into early flower.

Nah...it would mean I would have to run 4 x 1000 watt HPS at around 4000 watts just too expensive and alarming for power consumption... the 2 tent set ups now
have 24 COBs in each and I'm only running 1800 watts of juice to power them.

Thanks bud.....it did start off just growing a bit of persy for my recreational use but hey it morphed! LOL

I went from 2 plants to 4 to 8 and now with these cobs im planning a space for 12, with more cobs and scrog...
Funny how that happens....lol

Nice Tex looks awesome!!! So much for not being able to finish flowering with these COBs! LOL

Yes it is...especially if you have mates that like to smoke when they come round for coffee! LOL

If you don't mind, so would 12 cobs be like 3, 4 cob bars spaces 12 inches apart? Ive had this stupid little project going and i just don't know how do figure out what the foot print is going to be.

This was my previous set up.
and for me the 3 rows of 4 COB's work well. The reason why I went with the 1 meter square frames was they were cheap and a standard size, if you want some specific
size of the profile on the frames that i used let me know.
Ok I made up my own frame of 1 meter squared 3 rows of 4 COBs they suggest for the best foot print to have 4 rows of 4 COB's in a 4x4 space but I think it's a bit excessive

Ok so yea i think i fucked my project up a little. Im putting my cobs at 1 foot on center on the bars. Im making 3 bars. I just don't know how far apart to place each bar. A foot apart? More then that? This is a pic of what I'm working with. wanting to do a 4x5 foot foot print. the bars are 4 foot long. Please give me some advise. Id much like advice from people gardening then all these math problems and data sheets and shit, no disrespect.

You haven't fucked anything up I just used a bit of common sense when it came to spacing and because I made a 1 meter square frame.....for me and you'll have to forgive me
if you are not use to the metric system but my tents are 1.2 metres by 2.4 metres so half that was 1.2 by 1.2 metres or 4 foot by 4 foot. Anyway my thoughts on spacing was i would have the frames
100mm from one end of the tent a 200 mm gap in between the 2 frames in the middle of the tent and thought that would be OK because you have the 8 COB's in the middle of the tent providing
enough light coverage over the middle space of the tent. I think that's heaps of light coverage and remember light is only 1 factor to get right for a good growing environment....I must say though I do
like the CXB's....trust your eye!! There is a couple of good phone apps like RGB and RGB light sensor you can download on your phone and check PAR readings. Hope this helps.

How accurate are those phone apps on PAR readings?

Good question....they are not too bad but it's mainly to give you an idea about coverage with out spending a lot for a good light meter.

Yo Mongo, if your bars are 4' long line match them with the 5' side of your footprint. Then space the bars about 38" total, first bar at 0", then 19", then 38" on center. This pattern should give you a good spread in a 4x5' footprint. Does this help, are you running the cobs a 1400mA?

Fuck yes it helps, thanks!!!! So even though i put the chips 1 foot on center on the bars i can still go 0-19 o/c then 19-38 o/c? And yes i think there 1400mA. Id have to go look again. Thanks dude and if your sure about those measurements I'm going to rock those. So 1 foot on center apart is too close?

I think you would have some hot spots if your bars were only a foot apart. You want more spread, so placing the bars 19''s apart on center should fill your 4' side of your footprint. Then the bars themselves are 4' with 5 cobs, which should blast the 5' space very well. Damn your going to blow up that space. Should be able to yield well over a g/watt. What drivers are you running?
I notices with my array that between 12'' and 18'' away from the tops of the plants I get the best growth. Any closer and I get some bleaching.
