question for the breeders here

I'll have to examine that much more closely, then, because I'm not usually able to sort it til they're out of the opposing stage. I can see it the moment that first node alternates, but usually not before. :)

all indoor plants I have grown will show sex 4-6 weeks. Some will take a bit longer 8 weeks never longer then that. You dont need to change the light just keep vegging until they show.

I think it's from a kind of adaption to maintaining an optimal branchy-like survivable structure. hemp would grow straight up,,, outreaching branches with flexible structures replaced them to cope with broken branches from wind laden terrain/ and a lack of growth with the onset of flowering. Things like potency, taste, or whether or not the trait is dominant in the heirloom varieties could be a few things to consider if you're making seeds.

Yes here is Kali Mist. the main stem on the right is easer to see. I have had many plants do this. You can see she has 2 buds a space 2 buds a space all the way to the top. This plant has to much space between the nodes so I would not use it to breed with.

out of curiosity is that plant not topped and the lower lateral branch is as tall as the main stem? as to maturity I think they all mature at different rates, the auxins/cytokinin help speed this up or slow it.... personally with the plant shown it seems it's apical dominant hence a lack of branching though the branching appears opposite and not alternate .. if topped more lateral branches would form and all shoot up to a sim height.. some would say that's a good thing and perhaps an adaptive fitness!

edit: also I think the higher the level of cytokinin the less chance of apical dominance.. therefore these sorts branch more freely and are often leafier plants

c-ray

can you show a closer pic of the nodes, to be certain that they are actually in line and not slightly off..? why is it an advantage for a plant to flower like this?

not on that plant she up in smoke .. I do have another one that has alternating on one main stem the other is none. This one is Pine D. I want Alternating and close to ea other it makes larger cola's. You can see there's allot of space between the nodes on none Alternating stems. Big full cola's will have alternating nodes 1/2" apart or less. Its easy to see when you look at the fan leaves for that node. They are directly opposing ea other.

This one is lightly off on the right side by a few MM. the left side is good


This side is alternating

Leaf to bud ratio, dependent on growing style but if a plant like that is multi topped all axil stems will shoot up with the opposite branching pattern, dependent again on veg time, you can put more of them in a tent than leafier types but this is ALL dependent on personnel growing styles and needs IMO. You could find a superb smoke with a plant that grows like that! would you chuck it? or learn to grow with it? the stem elongation would be down to higher auxin levels and could suggest a higher photosynthesis rate.

is the t5 tri-band 6500 K ?
the HPS Digilux has more blue and purple if thats true
so not the usual HPS spectrum

i will just pull a highly hypothetical thesis now out of my nose
which i explain the following:

maybe you are missing a little red, thats y plants do not grow ("mature") "fast" enough
or other way explained the blueish light keeps the plants "young"
clones are older so they may strive maybe more to alternate like in your case now

blue light has a higher frequency which might influence the nodes cause the plant orientates
according to how to catch the spectrum of the light the best

someone ever noticed a difference in the nodes whilst vegging and flowering
with MH light or other blueish lights only maybe?

but maybe its really just the genetics as you assume, i guess that might take a while
to find that out.

sorry if this sounds stupid or anyhow, i couldnt help myself trying to come up with something reasonable.


The Kali was grown with Hortilux and Planta star bulbs. The Pine D was plantastar/Horti/Dgilux. I just replace 2 bulbs to make all of them Digilux 2 months ago.

okay thanks for the picture..still not sure what you are hoping to achieve but good luck!

Im not trying to achieve anything. I asked a question. Some say all plants have alternating nodes some say they dont. whats the correct answer.
 
i think the reason your not seeing more documentation about this is because most are not running the extensive veg time on their seeds like you are.i try to let everything mature and show sex like you do before flipping.sometimes more than the time expected sometimes less.really depends on what im trying to accomplish with them in my rooms.trees vs topped vs sog whathave you.

my deepchunk breeder did this and alternated.was not aware it was a positive trait aside from something happening as she matured.i have 20 choc rain in veg right now that I am looking for a papa out of.i can clearly see alternating vs non alternating at 1 month veg no sex showing.certain phenos just have closer nodes is what I have chalked it up to be.have a sick instant karma doing this too.guess i never payed attention to the leaf stems position.imho its more important to focus on other traits such as hollow stems,smell,structure,node spacing rather than trying to lump spacing and alternating into the same category or trait when it is really two.what im saying is im sure their is an exception to the rule.sooner or later something like alternating leaf/node spacing could lead you astray with your project.i mean no offense or disrespect.just my thoughts on the subject.ive read through just about every thread/ book/article on the subject over the past 5 or 6 years and have not seen anything substantial on the subject in that time.node spacing yes.but alternating nodes no.

Crap... did you already say what your photoperiod is for vegging? I wasn't kidding, I have only ever done this using natural photoperiod.

When i plant indicas outdoors in the tropics they flower very quickly, way before they get a chance to alternate. you should check Autos to see if they alternate as well?


What is the difference anyways? do you find that alternating plants are quicker or something?

I use 24 hrs on t5...

bg: It has been posted what the benefit is having alternating nodes. Short answer is larger yields.

lol there one, thats what im taking about. Im seeing allot of plants like this recently.. I know im a old fart with failing memory but I remember back in the day selecting plants from genetics that had alternating nodes and within close proximity of ea other because they all did not have it.. This was some of the traits I looked for when making my selections to breed with.

That a cool pic Raco. she even has double stems going on. I like trait would probably keep that girl

EDIT: Oh I see it. He topped it way up there..I agree at the top all plants should have even out there nodes by then.
