how does the sun give free energy in an indoor grow.... I don't have solar panels
why would you say that after just posting pics of plants outside claiming they are yours? Again, flowering, not vegging, and no comparison to draw observations from.
I am doing both- from seed and from clone- And I am doing both- Inside and Outside- and have done it so many times for so many years.
When in an argument, when a person would respond to a claim with a counter claim using unrelated data- it typically indicates that person understands their fallacy and is unable or unwilling to admit it.
You cannot draw genomes from a genetic pool to produce different results within the same strain when growing with clones. This is done through breeding practices and only manifests through seedlings (genotypes and phenotypes). These genomes have a great amount of influence on growing patterns, flowering times, potential flowering structure/density/smell/potency..... and then you get into those that regulate the plants reactions to threats/injuries/diseases/pests which will also greatly contribute to overall yield. So how many generations down the line, the cloning methods used, acclimatization (as this is an outside thread/question), all and more have a great impact on the answer to the question. Similarly to at what methods of breeding the seeds are produced would also have great impact.
Another contributing factor- Having grown the same strain for years, and understanding that strain very well and how to work with it, will greatly impact my potential results with the strain. Knowing what works best through trial and error, observance and dumb luck. If its not a strain that is familiar or one has experience with, or if one is not familiar with how to "read" the traits of strains, then there is an impact of potential yield.
The picture I posted shows plants that vegged in the same indoor area, rotated for close ratios of light exposure. Same soil mixes used, same transplant times, the clones are about a week older that the plants from seed (as you indicated you believe to be a fair starting point). So it is relative to the conversation in comparing the two. The picture I posted does not show clones put outside versus seedlings started outside, which I believe is closer to what the op of the thread was asking. That comparison can easily be done- starting now or very soon, as I am in just a position to do that.
I make claim that neither is better or best- that nothing is guaranteed or exactly the same- but that both are different in a multitude of their own ways, and a great amount of joy and learning can be achieved by experiencing it for ones self to draw our own ideas from observations and base our future choices off of that.
