Could you explain to me.
16 plants under four 600w lights will grow to the same size 6 will.
It's only when you start to have more then four under one light that they start growing smaller as they don't receive as much light as they would if it was four or less plants.
Effectively I believe if he had put 16 plants there instead of six it would have yieled 2.66 times as much as what it will with six.
But I am assuming he didn't want to possibly have another badyield compared too his fist one and wanted to test himself I guess.
Either way it looks great and I like the way the lights are setup.
I've grown 40 under 1 light(sog) it's about the light/canopy and taking advantage of every bit in the most efficient way, whole bunch of little plants with zero vegging or 1 vegged long enough to take up the same space eg. scrog
Then theres vertical height to take into account, you don't want them too tall because the light can't penetrate and you end up with a shitload of tedious pop corn to trim. Light doesn't do much good after about a foot down.
Ozfarmers working big pots too, more smaller pots means more plumbing and work. Not to mention I'd rather have 6 then 16 if the poo hits the fan, much better.
Also Jim the general rule of pot size/root mass which is basically an ounce per 4 liters so that's 16 4 liter pots or 1 60 liter pot to achieve a pound, rough guide.
Hope that makes sense, the only thing that's costing is the extra veg but with a dedicated veg space that's no big deal, but that is now 12 plants right,
What you reckon Jimmy,
Good vibes bro.
Edit: there's also the gram/watt ratio, pulling down 2lbs per 1k is where one strives to be at.
You can measure yourself from this point of view but some people insist taking into account veg time so that 2 per light per 8week cycle, it's not as hard to achieve with plenty if veg
