So I read through all 9 pages. The first few pages the guy saying it wont increase yield is retarded. Bigger root system equals bigger fruits. Period. As far as doing the air pruning to clones in those upside down V pots. Seems kindve useless as clones dont have taproots. But using clones in the 4inch cubes to get a nice thick knuckle inside the cube. But after you transplant to a bigger pot or table whichever I would let it veg to let the roots expand out into your media then flip. And I think 4inches is the magic number. If you run seedlings in a solo cup like most people a cup inside a cup. With holes poked in the bottom of the cup for drainage. And put the cup inside of another cup. The tap root will jus keep growing and circling inside the the outside cup. It doesnt air prune it really. But I've found using single cups with tons of holes drilled in the bottom and sides of the first two inches of the bottom of the cup and set the single cup in a tray. The taproot stops growing length wise. And it starts shooting more side(lateral root) growth. And btw a solo cup is 4 1/2" deep. But back to my cup in a cup. If you let it get a good root system in the cup. And pull the dirt and plant out and wash off all the dirt. There is a gap on the taproot. Between the first set of lateral growth roots and the next set of roots. I jus drew a retard cheap paint pic to show what i mean. The yellow line is the soil line. The first red line is the first set of lateral roots. Then theres a gap between it and the next set of lateral roots. The second red line. I think the air pruning ig done right. Does away with that gap between the lateral roots. I mean theres still a gap. But not quite as big. But anyway, if you air prune making the first sets of lateral roots closer together also air pruning lateral roots. Makes more root growth. Get your root system nice n thick inside whatever your using. Then transplant to a big pot say 5gal soft sided pot that air prunes. Let it veg and fill that pot. Then flip to flower. Makes for big trees. I think using 6 inch blocks will work too. But takes longer to fill out the block. But if you have say 6 sets of lateral root growth in the first part of the plants life. It makes for a healthier plant. Which in turn, INCREASES YIELD. And also kindve makes the plant grow faster(more vigorous) increasing root zone production.
Sry for the shotty pic. As I was in hurry.
