Here's my 2 bobs worth, it may or may not be applicable or of use,
When it comes to nature I respect it's ability to produce a plant in it's optimum form given it's surrounding environment. We can help it along and perhaps simulate an ideal environment but the plant knows best how to make use of it. I let my hops grow how they want. I hardly even train them, they know where to grow.
The most flowers on a plant may not necessarily mean a good quality individual flower, which is what we want when it comes down to it.
A friend of a mate of mine's uncle is quite an authority on the hop plants close relative. Here is some of his wisdom which may be applicable, and no I'm not stoned or addicted to the stuff.
The flowers closer to the ends and top of the plant have a higher concentration of resins.
Tipping or training the the plant horizontally will not increase yield, only make it easier to conceal.
Ultimate quality flowers will be produced from a single tip.
Hyproponically grown buds may have a stronger potency but may also taste like shit and sometimes almost unidentifiable as the pure product. Also the effect is unnatural and can lead to worsened side effects from it's long term use.
The time of harvest is very important to flower quality.
The amount of direct sunlight that the plant receives is the most important factor in producing quality flowers.
When the time is right the plant throws everything into flower production, even takes nutrients from it's own leaves.
I would have to consult the knowledge source and contemplate some more but I'm sure there is a lot of other factors which may be applicable.
It is also well known that herbs that have somewhat struggled to grow will produce the better quality and more fragrent oils than those that have been fertilised to buggery in an attempt to increase growth rate and yield. Sunlight, once again is a major discerning factor here. The plant needs as much as it can get to a logical degree. It's better for a plant to put it's energy into flowering at the right time rather than putting it into growth in an attempt to gain more sunlight.
Hope some of it helps. I'm not trying to turn this into a dope growing debate just wanting to raise some probable discerning factors.
Cheers.
