guys, I had some problems in my grow as you can see on the last posts, anyways I did all again from seed, now its all growing very well without problems in the beginning.

However now I am having a preoccupation/worry about the height, like not all plants are in the same age(2 plants with 3 weeks younger, the first 2 plants of the photo) I am waiting that 2 plants get more height to switch to flower.
The oldest plant is from July 13th, others from 18th and 23th July, and the 2 younger from 7th August.
So I did supper cropping on 1 plant that was super tall, bc the stem is woody and won’t bend easily to do LST, I did on 1 plant 2 days ago(photo attached), and now I think I will need to do on others...

What is the average height I need to keep on vegetative stage to switch to flower without issues with the height till the end ?
They are reaching 50cm... I think I need to keep on 40cm maximum on vegetative stage, my grow tent has 2 meters, less 30cm for fan and light, so around 1,70cm usable.
I am keeping the light closer to not stretch too much.

The problem is...doing the super cropping it is getting super crowded, the branch falling on top of the other plants, i am pissed off with it, next time I will do 6 plants instead 7... 1 less plant will make a lot difference for the space, definitely!

They was trained to have 8 colas on each plant and reduce the height.

Am I doing right? suggestions?

Thanks

No idea how big your tent is but you sure did'nt figure how big these plants get. You could use some heavy pruning now. Take off branches, you don't want them laying on each other for sure. Do it prior to the flip and know that they'll stretch at least 4" if not more. I have a 3x3 and i won't put 4 photos in there but i'll do 3 cause i veg. for almost 2months and train them LST and tie them down. Much easier to manage air flow, less issues.
 
I could be wrong but that plant in the back looks super stressed to me.(the first pic) The leaves dont have consistent color, some are showing deficiencies and the top leaves are tacoing or way too thin for my liking.

yeah I am monitoring, but she is good at all =D I will do super cropping on all, and switch to flower after they recover a little, like 1 week.

150x150x200cm grow tent size
I will do a super prune today, take off every low stem, open space in the middle of plants, super cropping all others until 40cm or less and switch to flower after recovery, like 1 week.
What do you think?
and how can i control height on the flower? is that possible, bc I do not want to herma them...
 
If you bend al those branches, every single one of the now exposed sidebranches will shoot up. You might end up with a carpet of buds you might not be prepared for. There's always the option to top back to a comfortable size, wait till they show good growth again and then flip. Early lollipop can help or as suggested earlier heavy defo and lst as much as you can.

I would give a little fertilizer on that bent branch its brown and holy cracks ,its dying leaves are wiltty , might be able to save it or clone it.

I am really worried bc it is too crowded, and on the flower it will be a problem, I am thinking about take out exactly that plant that are with brown leaves, and it will be a fucking upgrade to the ventilation system, healthier plants.

Ok yeah your right to open that area look were your hand is if u have raw honey put on crack branch tape it tight u have room for at least 1 inch tight tape job then turn that branch to the outer edge where ur hand is and tied it down there's room there 😉

To control the height ya i see alot of nets , homemade netting . To much, many plants for me limit is 6 im good for 3 at a time maybe 😅
 
that 90 degree angle looks like it is dying to me , going brown...by bending it over you must have blocked/crushed 50% of the capillary tubes which bring the water up, so that branch will only get 50 of the energy to it. i would snip it off .
 
I’m surprised nobody mentioned your light

It’s really close to close by the looks of the plants

You could easy move that up to 20”-36” away & should do

What wattage is it & is it on max settings

The bent branch is what it is however once you move your light up you will get more height to play with remembering that they will streach when you flip them

They are big enough to flip now however I’d def move that light up first as the plants are very stressed from it & id you don’t they will get light damaged

Idk bc this plant are growing very well , I also cracked the 2 stems of each 4 colas, mannnn , I tightened them up to recover, but it is a very strong plant, seems she don't even noticed it, sick! Instead it, she is growing more on the middle of the plant Anyways, thanks, I will keep my eyes on it.
Cheers!

Updating...as y'll can see it is growing very well after the last LST I did 4 days ago, I had some problems chipping the stem, I tightened it up and that is it.
2 younger plants were low comparing to the others, so I put a stand to raise it.
6 plants in a Mars Hydro grow tent 150x150x200cm + 800W + ADlight(2x Blue on vegetative and 2x Red + 2x UV + 2x IR on flowering), each ADlight has 27W

Since this was my first grow, I think I gave it too much time to vegetative growth, which resulted in the grow becoming very crowded and putting the plant at risk of exceeding its height limit. This is a lesson learned for the next grow.

Anyways I bought the 90 degree plant clip to control the height if necessary on the flowering.

I am about to switch today to flowering, any recommendation?

Thanks y'll for the help!!

Wow im blown away that grow setup awesome.
 
Setup:

Mars Hydro grow tent 150x150x200cm
Light FC-8000 (800W) with Samsung LM301H EVO diodes + ADlights from Mars Hydro
6 Plants in a 20 Liters Fabric pot
CO2(Flowering Stage)

Obs.: At the early vegetative the light was 30% until late vegetative 50% and now increasing to 60% at early flowering until 100% at mid flowering.

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

Genetics from Royal Queen Seeds:

Strains Since

Gorilla Glue 13-07
Shogun 23-07
Royal Runtz 23-07
Hulkberry 17-07
Cherry Pie 07-08
Green Gelato 07-08

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

Technics:
Topping(each plant has 8 colas)
LST
Mainlining
SuperCropping

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

Like It is my first time growing I think I will gonna have problems with the height(I hope not), I didn't expect them to stretch like that, next time I will flip with maximum 40 cm plant size! Now the tallest plant is 58cm.

I flipped October 7th to the flowering, added ADlight 2x Deep-Red, 2x UV, 2x IR, 27W each.
Deep-Red - In sync with main light.
UV - 10 min per hour during the main light cycle.
IR - 15 min before and after the main light cycle.

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

The grow is clean and tidy, I putted all stuffs outside, but kept the carbon filter and in-line fan inside bc of the noise from the fan, and I could put the carbon filter outside, but I couldn't hold the carbon filter pointed to the window like I am doing now with the flexible duct, so I gave up to do this, losing around 20-30cm on the top...It is bc I am very worried about the height they will take on flowering stage.
The plants are reaching 60cm height...even with LST and supper cropping. Anyways let's grow and see what happens!

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

3 Questions:

1- The plants are getting big and I need to improve the air flow. Do I need more 1 or 2 oscillating clip fans?

2- This week the average humidity is reaching 94% - 97%(the winter average here is 88%) and inside the grow is 65% with Lights ON, I am worried with this on flowering stage...and with the lights off, humidity increases.
I moved the inline fan that pushes air away from the window to help decrease humidity, I think I am increasing the humidity pushing air in with 97% humidity, that is why I moved the fan away from the window and maybe I will need to buy a dehumidifier, what do you think?
Obs.: I have an in-line fan 6" inside to blow air out and active intake another in-line fan 6" to blow air in.

3- That plant(Royal Runtz) I am showing on photo is too crowded, It has 8 colas, but without mainlining and I forgot to LST the second topping, so she lengthened a lot and I needed to supercropping, that is why you can't see properly the 8 colas as the other plants.
The doubt is: Do I need to prune more ??

Please, help me guys!

Thanks!

I'm a first time grower also , I say your temp should be 74-76 f at night and fans to suck out moist air u have to play with it until u get humidity down in the 40 s dialed in .u have a lot of space to control. Where is ur grow room?

I have 1 plant 2 more weeks then I flower , when flower comes i remove humidifier
