Veg and stretch. Can someone explain this?

[bloomingdale]

So I have a question. I've grown this 50/50 hybrid twice now and i've noticed something. The first time I veg'd til each plant was 24-30'' and I ended up with 48'' plants. The second time I veg'd til each plant as about 12'' and still ended up with 48'' plants lol. Whats up with that?! Lol

 

[Hydro-Soil]

Both times from seed?

Both times from clones from the same plant?

Need more details, way too many variables still.

Stay Safe!

Same strain, from clone, same mother plant both times. I'm curious to why it happened that way. Almost like the plant didnt feel the need to stretch as much because it was already pretty big.

 

[Canniwhatsis]

2 grows? That is NOT enough experience to go on IMHO......


To put my $.2 in the bucket tho,.... if you did what you say you did,..... it's down to the lights.


You never said what your lights were, or how far from the canopy? I've watched a buddy try and grow under a south facing window with a couple desk lamps to supplement...... Suffice to say,.... well you can guess.


NEED MORE INFO!!!

 

[bloomingdale]

Lol I grew the same conditions both times. I only changed the height at which I flowered the second time

 

[bloomingdale]

So the plants roughly doubled the first time and quadrupled the second time.

 

[Canniwhatsis]

What lights,... Growing medium,.... Nutes?......




Still lots to be reviled.

I am not a guru or anything, but in my experience phenotype of a given strain has everything to do with that. I base that on the Afghans I am running of which I took 3 different cuts. One of them stretches way more than i would like, maybe due to it being slower to flower in general. The other flowers way faster...I mean it can't finish fast enough, so stays relatively low. In other words, you're going to have to grow the same cuts the same way a few times to really know the phenotype and how it will stretch, etc. BTW, I am talking about a LED grow, plenty of watts...at least 90 per sf. I have grown this same cut in soil and passive hydro and the fast one i describe acts and develops the same way, only way faster in hydro. It's all phenotype, IMO. Well, mostly, some strains obviously grow larger than others, but within a given strain, some will stretch more than others, if that makes sense. I think you can count on doubling or better in most cases and over triple with Sativa. So veg at 12 inches gets you over 48" w/ a sativa, but could be as little as 28-32" range w/ a 12" Indica clone.

for what its worth bloom, ive noticed similar things. I think if there isnt an adequate root mass (determined by the plant) then it stretches harder and has longer internode spacing. if it feels comfortable it will stretch less with lesser internodes and more branches to become a better plant. If you look at true SOG growers they start with a tiny clone and they get quite big in a few weeks. I dont believe tree growers get the same effect.

It could also be PH, EC, RH, or temps differing too

 

[DHF]

Yeah.....Too many variables to say , but as Dave said Plants respond to external as well as internal stimuli , and without knowin all the "X" factors there`s no way to explain it.......

I had the best luck controlling stretch and internode spacing by veggin with T-5`s right down on top of the plants till they went in the flip rooms with the bare bulbs where they exploded with stretch and rootmass building , but with stacked nodes instead of the plants growin stem in between puffs of nugs.........

Good luck....DHF..........

 

[bloomingdale]

Davethenewbie Thanks I think youre right.

DHF both times i veg'd them around my 600w hortilux and to be honest the growth was great. when you were vegging with t5s were you growing 3-5ft finished plants? or small plants?

 

[Hydro-Soil]

Did you grow from seed and take clones from the same mum?

If so... that would easily explain it. First set of clones were taken when the plant wasn't fully mature yet.

If not... Keep looking

Stay Safe!

I'm sure he'll correct me if I'm wrong but DHF was running v-sog with racks arranged in an octagon,so he was vegging small plants.

I'm almost done with my first vertical grow,donut style with five plants in 3 gallon pots of FFOF and I started out this groe with the intentions of just going horizontal like I always have but then half way through veg I decided to switch to vert and I think If growing donut style (plants arranged in a circle around vert bulb) or true tree style (lights on all sides of plant) vegging vert would be best.Of course tree style you could veg horizontal for a while but I would think once they hit 2'-3' in height that you would want to start switching them to vertical for a real strong christmas tree shape.

I personally have never experienced clones of a particular pheno stretching like that...if the mom stretched 2x her height,so did her clones.Same goes for any clones from a mom that stretched more or less,clones performed like moms did.This leads me to believe your light is in a fixed position and that your clones (being that they were smaller than the moms) were further from the light than the moms were,so the clones stretched toward the light.

add this to the possible list : distance from light and light bulb quality

Add this too if doin this shit for real havin a digital light meter to know when bulbs drop off below optimum standards/lumen output.......

I changed my bulbs out every yr in each flip room cuz they only burned 12 on and 12 off continuously.......but.....with multi-taskers as in veggin too , lumen life usually cuts in half to replace em every 6 months.......regardless.....

T-5`s , horizontal MH`s for pre-veg before bloom rooms is a good thingy.....anyways......My 2 cents from all them yrs....

Peace.....DHF..............

 

[Avinash.miles]

perhaps your bulb wore out giving less light causing plants to stretch more the 2nd time around...

pretty much a shot in the dark here, i think the consensus is that there are too many variables, stretch is hard to predict untill mutliple "runs under the belt" as it is said....

What would optimal lumen be? I read everything between 50,000 - 5,000... (looking at the lumen-chart from different lumen/"away
its like.. if you have a solid screen at 10 inch diameter youd "capture" 42,000 from a 600w hps. Imagine its kept in a 30 inch high screen.. thats (pi x diam20" x 30" high) 1884 sq-inch (1,2m2) blasted by 42k lumen. But what if you make the screen at 15" youll have 18,7k lumen at a 2826 sq inch (1,8m2) if height is still 30".


Eeh, lets see.. That gives 1,2 m2 @ 42000 lumen = 35,000 lux?

And the 15" @ 1,8 m2 @ 18700 lumen = 10,4k lux?

Eeeh.. What am I missing out on here? If the 35k blast vs the 10,4 aint the 3,5 in difference vs the 33% area-increase... it should be worth to expand the diameter of the screen to increase the usage of space with 0.6m2 (or 930 sq-inch). Where is the break point?


Eeeeh... Oh shit, I shouldent be thinking while high.. I just had a small, simple question. My mind derail at once!

 

[Femora]

Soooo... Was my question to stupid/to good to be answered, or am I just beeing ignored? -.-

Well, B U M P!
