She's coming along...A few bumps in the road (My fault) as far as not adding enough of certain amendments to the used soil she was grown in..I carried her along though as soon as I seen some issues with Foxfarm Big Bloom..Right now she's at about day 86 from seed ( breeder notes say 85+ and 2 weeks extra for tighter nugs). Nugs are super hard already, no give to them when you gently squeeze and she stanks something fierce..I took a small popcorn sample I found right under the canopy a few days ago..Threw that in a cone and Super strong smoke, one good hit when I lit it and it hit right behind the eyes..snow white ash on it and it wouldn't die out lol very nice..At this point I'm just letting her fade out as you can see,and ride out her last 1.5 weeks..Just trying to squeeze all I can out of her before she's chopped..Cobs have been sitting at 20" for anyone interested.

Can't believe the size of her. That's one hell of a plant for 2 cobs

My memory is terrible. Completely forgot about your change over. How is that going? Did you get the rubber?

Didn't get the rubber yet but I'm definitely going with that place, $36 shipping is nothing..I'm also going to grab that roll of Reflectix from HD you suggested..I'm just waiting for this plant to finish up and then I can pack up the tent and bust out the blueprints.

@BigSm0, I have 2 meanwell 60-1050 drivers, I just purchased two of your almost complete, which screws would I need to put them together? I have 20mm nylon spacers. Thanks

I don't think the spacers will not line up with out the proper brackets. There is also a certain way the wires need to be run and the cobs need to be mounted so they stay attached to the heatsink. Not sure on the screws as mine come with all the hardware including screws.

Hey @BigSm0, got my "almost complete" today! Thanks, They are some beautiful Cob lights!
My question, what is the minimum height for these lights?
My tent height 5'3"

It's not necessarily about your height, what is relevant is the distance from the light to the canopy and this will vary depending on your strain and how it reacts to light. With these COB's I have found a sweet spot in the 12-14" range myself for optimum growth and no plant burn with most of the strains I have had under them so far.

Hey @BigSm0, I've seen nothing but great feedback from your creations so I think it's only right I jump in and see what the fuss is about lol
I've a few questions though if I may,
I'm currently growing in a 3'x2' area under led with pretty good results so far, but I can only really grow 2 at a time realistically. I'm looking into either a 4x4 or a 4x8, more than likely the 4x8 though. So obviously I'm going to have to raid the piggy bank for new lighting as the 2x3 will remain a veg room.
How many of your cobs would you recommended to give good coverage and also I'm not what you would call technically minded, im no idiot but i can barely work a smartphone haha. So would your almost complete packages be abit confusing for the likes of myself or is it pretty idiot proof to assemble a setup? Also the big question...how much
Cheers mate

Hey there. For the 2x3 I'd go with 2 cobs in total. The 4x4 I'd go with 4-5 and 8-10 in the 4x8. The almost complete are less expensive but also require more parts and work to complete. Drivers, wiring, power cord, and the biggest part is a frame. The frame takes away from one of the biggest benefits of the single hanging AutoCob which is its versatility. Adjusting cobs individually is very beneficial as plants rarely grow at the same heights. This decision is completely up to you. Are you from the U.K.?
