How big should my plants be before flowering?

Hey guys my tallest plant is 25inch and my shortest is 22inch, I was wondering if I should start flowering, this is my first grow and I don't want them to grow too tall and over grow my room, they have about 5 feet of grow space. I'm wondering if I should start flowering or not

Flip them bitches !
Flip the when they are 2/3 rds the size you want to finish with.
This gives them 1/3 to grow in flower.
At least 20" tall before flower.

yeah some strains just about double in size during flowering

...and some, *cough*Tangerine Dream*cough* triple in goddamn size till it's nearly coming out of the top of your goddamn tent.

Cannabis typically doubles or triples in size during flowering. Sativas can stretch even more.

Bear in mind that the plant shuld be flowered so as to coincide with the capability of your light. For example there is no point growing a plant 5 feet tall if you're using say a 250w hps etc, the light will only penetrate such a distance and the majority of the plant will not receive enough beneficial light to do anything worthwhile, it just becomes wasted.

Size or time I think both become important when turning to flower. I have decided I will follow a very strict schedule related to time because I have a space issue (heighth) so I veg for 35 to 40 days to meet my situational restrictions. I generally see about 1/ 3increase in size with my particular strain.

I grow em wide and flat so I typically get mine to about 2ft wide and then flower.

depends on the strain man, what kind of growth you have happening, are you aiming for specific weights or is this just for fun. this is a question where the answer is different for everyone and only comes with time

yea but be careful i switched my northern lights at just over 2.5ft and they ended up over 7ft tall and frankly i didnt see much more yeild than smaller better grown plants have given me

This happens too but it comes down to learning and knowing your strains. I have a strain that I actually get more when i veg for less time (significantly more).

I was in the same boat as you. My plants are around 2 ft and my grow tent is 5 ft, I was waiting on the to be fully sexed or at least show signs. But I had to switch them to 12/12 yesterday. I'm already afraid they are too big for my tent.

LST , if u want them to stay shorter then flip the lights & in week 2 tie them down.i use long thin red rubber bands & plastic coated paper clips.i like the bands bcuz they have some give. IMO
