I agree 100%. The one thing this test has not shown is how a plant started from seed will do.
Being clones, they dont have one tap root and thousands of feeder roots coming off that tap root. They have dozens of tap roots with thousands of feeder roots. When those tap roots poke thru the air holes in the side of the pot they form a callus at the tip and start growing more tap roots off the part of the original tap root that's still in the soil. It's kinda like if you cut off the end of your finger, instead of having a nub, your finger grows two more fingers out of the side of the nub to grow as long as the original finger. Then those new fingers get cut off and the process repats itself.
This is why the plants are feeding so heavily. Instead of the plant feeding itself with small feeder roots they're gorging on nutes because they're feeding thru tap roots.
I got a delivery confirmation # yesterday on some new seed stock. Hopefully they dont get intercepted and make it here. The strain is Yumboldt 47 and I plan on using Air Pots for every stage of the grow. My biggest question is will that massive tap root from a seed do the same type of branching? Should be very interesting!
Nice explanation my friend. I think this will be a force in the future.
