Hey thank you sorry was confusing my self when you were asking about the wattage. i believe i MIGHT be VERY slowly grasping it lol.... you are asking the amount of miliamps i will be powering it with? The chips have a max current of 700ma which leans me to want to run them at around 500ma. The...

Still somewhat confused sorry if im being a pain here but to clarify is it when wired in series the driver output needs to be greater then (in this case) 25.3 v so i could use something like ameanwell hlg-185h-36a driver to power 6 of the cobs in series? Or can i do more ? Or less? ...Orrr...

Not sure if you can see it jn the pictures i posted but badically what i currently have is 2 rows adjacent to eacher set up X O X Id like to do X I O I X X = Mars 400w converted to cobs I = New cob build O = qb 550 (knock off) Hopefully that makes sense the way i worded it

Sorry what i meant by "board" was something along the lines of could i use 1/4 inch sheet of aluminum and mount the cobs to that like a qb ? or will it generate too much heat and id be better off with using L channels and heat sinks with the cobs mounted to heat sink ? Regarding space ideally if...

Sorry for confusion basically i wanna set up 2 boards. On each board i was thinking of using 2 drivers and 6 cobs each driver wired in series. 30.7 is max voltage so was trying to clarify if 6 cobs x 30.7volts each which equals 184.2 do i just need a driver with output of 185v or higher... or...

Thanks for the reply was wondering could i go 2 boards 6 chips in series 2 drivers each board for a total of 4 drivers if i understand correctly i take the voltage per chip multiply by how many chips in series and matching driver needs to have more volts in the output then the total amount of...

If i understand correctly take voltage x amount of leds so in this situation 25.3v x 24cobs = 607.2 total volts so the driver has to have an out put 608v or greater? Or run multiple drivers say 3 drivers 8 cobs each ?

Thanks. I presently have a grow going on 2x hlg 550 alibaba knock offs and 4x mars 2 400w converted to citi1212 cobs was looking to just add some more light in there the room is 7.5x 9.5 ft im using about 5x8 of it right now just attached a few pics to give an idea on lay out

Hi everyone. To make a long storey short like a year and a half maybe two years ago I was upgrading my mars leds to cobs based on a tutorial put out by growmau5 on YouTube. i mixed up what I thought I was purchasing bought the wrong cobs thought damn that was cheap ..got the package completely...

We getting colorful

Finished up mother/veggin room will throw some pics up abit later

Few more

Just a "few" update pics lol

Also just to mention the few runts in the back were just either sprouted or were germinated later then others and is part of reason canopy is slightly inconsistent along with the gorilla skittlzez two different phenos tall lanky sativa dom and squat bushy indica dom. So the ones that are farther...

Todays pics... just a few angles LOL ..there are a few that are a bit over watered in the back left corner and found a few spots on leaves where water splashed on and magnified the light causing a few little burns

Lol i think most make that mistake at least once.. sucked big time but took it as a learning

Not being your typical over reacting newbie and assume something is deficiency when its not and burn (nute) up 75% of your grow real good lol ...k.i.s.s. this time around lol

Hi guys sorry busy day yesterday with work and family but some more info Room it self is 7.5 × 9.5 ft but am not using that entire space as you can see in the pics Strains are 5 x auto purple kush 1 x blue dream 1 x bubba kush 1 x royal gorilla 1 x afghan kush "special" 1 x g13 1 x...

Sorry meant to say 24 x 5 gallon fabric pots

Hey guys just wanted to share round 2 getting underway, after last round's fiasco excited to be starting again will share more details later today as im at work but for starters Lights - 2 x hlg 550 v2 3000k alibaba knock off 4 x mars 400 converted to citi 1212 3500k cobs Cooling - 10" exhaust...
