I can only tell you that I don't grow more than one plant per Autocob.

what do you usually yield per plant when growing Meph autos?

Im trying to see if i can squeeze a good 7-8 ounces out of this grow but looking at the Meph section got me thinking i need to add another plant because Im see seeing alot of sub 100 gram yields from their plants

Try to remember this is your first grow and keeping it simple is always a good thing. New and old growers sometimes tend too get greedy, try too much at once and wind up with decreased overall yield and/or other issues. If you don’t know the strain you are growing personally, you just can’t be sure what you are going to get. You might be a natural grower and two plants will blowup, completely filling that 7 square feet or you could put three in there, stunt them, and get greatly reduced yields, I wish you the former I have nine square feet and use 15 liter (3.9gl) pots and restrict myself to 2 plants. I only go with more plants when I use my 8.5l pots. In addition with a little training and a screen you can do this with one plant. Or you could make this beginning growers mistake and try too much for their first grow. And that was at least four weeks before harvest and had to work my butt off to get it to the finish line. Believe me, you don’t want that for your first grow. K.I.S.S.
& for your grow.

thanks for the advice.Im think im just gonna stick to doing 2 for now.

Hey guys, total rookie here. I am just about to go into flush with my first grow under x8 3500k AutoCobs in a 5x5 tent. I am very happy with this set up and want to improve on it next run.
I run the x8 in a 3-2-3 configuration in the tent at this point.
--X--------------X--
----------X----------
--X--------------X--
----------X----------
--X--------------X--
I would like to add 6500k lights for middle and end of flower. Anyone have any advice? How many auto6500k lights should I be considering? Would they replace the 3500ks one for one or run in tandem with the x8? Yes, I can manage the heat, so that is not a factor for me. At x8 that is 1200w, so thought adding to that might be overkill. Lastly, what configuration would you run the 3500k and 6500k setup in the tent? Thanks in advance, so happy I fell upon this forum. I know I could email BigSm0 and probably get these answers but figured I would get his final opinion right before I place the order.

I would like to clarify something as I’m confused, you say you run 8x3500k AutoCobs at 1200w. If you purchased those from @BigSm0 they should only be 55w each for a total of 440w.

I run 4x3500k in a 4x4 at 220w and in bloom I add a 2700k (red spectrum) and in veg I add a 6500k (blue spectrum) dead center as high up in the tent as I can go for maximum coverage with less chance of burning the plants, looks like a five on a die. That’s the 2700k in the middle. Total wattage only 275 watts. Not sure why you want to add a 6500k for flower, as that would be better used for veg.

Thanks for the response. I suppose I meant the equivalent of 150w each of hps or led replacement. Which makes me assume the intensity would be similar in PAR, so adding more to the already existing 8 would be too intense at the heights my tent allows.
I was simply looking at the description of the 6500k on the website which states resin production as well as veg. He doesn't have the 2700k listed currently on the website.
I definitely need to study more on the Kelvin thing. I do get the blue (spring/summer light) and red (fall/harvest light) concept in general. But I have heard many different things about the ratings. For example: 3500k great for start to finish as whole. Or 4000k good for veg, a little lower yields in flower compared to 3500, but higher resin (quality). And so on.
Maybe the better question then is: knowing I have x8 3500k autoCOBs in a 5x5 with the 3-2-3 configuration, What is the next AutoCOB I should be thinking about to Upgrade this set up? Assuming the 2700k was available from BigSm0, what would be the suggestion for flower in light configuration in terms of hanging pattern? Is the more logical path to dial specific veg lighting and THEN focus on flower light fine tuning?
I just want to upgrade man , just the next step. I want to get to where at any given stage of growth I am modulating my autocob collection for peak performance.

This my first run with the 2700k, but I have no doubt that it’s helping there is too much science behind it. I haven’t invested in a par meter yet, but do have a light intensity meter and can tell you these five lights at 270w produce more light than both of my former led panels at 360w and look what happened to them.


The 2700k is available you just need to ask him about it. He thought if he put it on the website it would sell out to fast and folks like us wouldn’t be able to get hold of them. That’s just the kind of guy he is and why I support his business.

As for your configuration and if it were my configuration. I would use the same pattern you have, but replace the center two with the season of your choice, 6500k or 2700k. If you still want to use the other 2x3500k I would put them on the outside center where you have nothing now. Those lights can easily cover a 2x2 area or 4 ft.² You have a 5 x 5 which is 25 ft.² so 8 lights which is capable of covering 32 ft.² and is more than adequate for your situation. With 10 lights I would worry more about light intensity than heat.

Hope it helps. I’m typing this while vaping some LSD at 4am so excuse my ramblings.

I run all 3500s and feel they do well from start to finish about the 6500 for flower the 2700 would better suit

I am limited on the 2700k and 3000k but do have them. I don’t like to list these guys on the site for this reason. As far as spectrum goes the lower the number the more red it has and the higher the number the more blue. My personal opinion is the 3500k does an amazing job as it is. Any addition should be more towards the red end. You could consider x-3500k and O-3000k
This is a setup I regularly see and recommend.

Another thing is you could possibly swap the center light with a 6500k and just use it for seedlings. As the plants mature start plugging in the 3500’s and at the start of flower you could add the 3000k so no wattage is wasted.


It won’t help now but I am gearing up to do a 6500k start to finish and a 2700k start to finish. I have higher expectations for the 2700k. The only downside to the 2700k in veg would be a bit more stretch which is easily fixed with a bit of lst.

Tag me in for this grow when you start it, should be real interesting.
