"siblings" assumes plants are grown in same chamber? with the same light source? is this light source horizontal? above the tallest plant? if so, then the shorter plants will probably produce less trichomes per mass than the taller plants simply because of less intensity overall.

but a room full of shorter plants as opposed to a room full of taller plants, both with proper light management, same genes, will probably produce more total trichomes per plant mass because a higher percentage of the plant mass will be illuminated as compared to the taller plants.

also, for the next person

- i know that "the middle" denotes only one plant could be planted there......................... ...................

etc etc.

sorry, i missed the "outside" part. but it's even easier to answer as both plants are getting nearly identical radiation.

if the shorter plant is getting what looks like greater trichome count and density it's simply more genetically disposed to do so.

thanks!

---------------

do you think it is a "genetic coincidence" that afghan etc "hash producers" are generally short (vs. equatorial sativas etc etc) ?

- or that there is a correlation between size and speed of flowering ? or something else etc ?

not genetic coincidence but genetic adaptation to their conditions.

i don't think that speed of flowering has much to do with plant size as long as the plant is "mature".

Assuming your hypothetical seeds came from the same mother plant:

Plant size is dependent upon its ability to produce roots (genes) and use the nutrients that are available to them. A small root mass has less nutrients available within its rhizosphere. (environment)
It is a combination of Genotype + Environment.

Trichome production can be increased or decreased slightly in different environments so I would assume that:
Trichome production is purely a matter of genotype.

I could be wrong however, as I'm in no way a geneticist.

Within a group of seeds (Diesel Ryder), I've observed on a few occasions the smallest plants seemed to be the frostiest.

I can't say this hold true with other varieties.

we need to utilize a concept I call "effective driving distance" of artificial lamps/leds, etc....

fluros have a very short efd. 1000 k lamps have a pretty long efd.

a little plant up on a 'stool' so that it's area is getting the same lumens as the top of the bigger plant would eliminate the possible conjecture of genetic differences.

Oh yeah...

Bigger plants and smaller plants all require light for photosynthesis but...

Size is irrelevant!

Plants are amazing! They can adapt & adjust to what they're given.
