about 24", They went on 12/12 about 4 days ago and stretch is already started, so I keep it high. She's grown 2" in the last 24 hours.
I plant to keep it at 16-18" when stretch is done, depending how tall she gets. This is an F1 cross so I don't know what to expect yet but am sure she's going to be big!

So how far away is that light to the plant?

The cross is pure Ducksfoot x Blue Dragon ( Blueberry Headband x Durrty Dragon )

Sounds awesome.
It's has nice looking fans too
But when u said one is the size of two hands it made the height look really high. Or I am
Probably both
I am planning a 1818 build shortly
But only 35w each and I guess I just expected it to look brighter.

its because of the reflected burple light, its actually amazing how much just those 2 can light that 4x4 tent! I figured they were a perfect supplement till I build a better light for that tent, then these will go into my breeding tent.

Looking at your setup did you not bolt the heatsink and cob to your frame?

I did not, the heatsink has a 'ledge' that I fit into the angle aluminum rails. When I was building it, I had ideas for expansion/larger space, and I wasn't sure how much spread my small tent and a single plant would require. It has pros n cons. I suppose one could tap the edge of the sink for a screw that could 'lock' it to a spot on the rail, maybe have multiple holes for adjustments, or some sort of 'slot' so you could easily slide them about, then tighten them down.

Im in a pinch fellas. I know what i want to run as far as cobs, which is the cxb3590 CD bin, im pretty space limited (28 in W x 56 in L x 5 ft H) im pretty time crunched as well, hence why im posting my questions instead of doing the research. I want to run 3,maybe 4 cobs in my space. But im stumped beyond that. Looked into a meanwell hlg120 driver, but theres so many specs and numbers im having a hard time grasping. My question for all those noble growers on here is this, in order to run 4 cobs, at around 50% efficiency (not to hot, not to cold), would previously said driver be enough for all 4? If not, can someone please explain in laments terms which driver would be optimal for 4 cobs all on one driver at about 50% efficiency?? And as far as votage goes, which is better to run, 36v or 72v? And what exactly does that number designate on the driver? Im a complete noob i know, but i am desperate to upgrade my cfl grow setUp.

If your just looking to veg in that space 4 cobs and 150 watts will work but if you want to flower you'll need to double that. Why not run the citizen 1212 cob? They are 36v, have multiple color choices and only cost 12$ each...

What's the catch on the cxm22? I'm planning an extension of my cxb3590s in a while, can this chip really compete? cxm22 @1050mA should fill drivers just like 36v cxb3590 @1400mA, is that correct? Does the cxm22 only come in 3000K? Cheers.
