How much taller do plants get in flowering

i have pictures in my other grow post but my ? is how much taller does your plant get when its in flowering i heard 2-3 times but is this is the first couple weeks of flowering or threw out flowering...my plants grew like crazy when i changed the light from 18/6 to 12/12 its been like 3 weeks now n there slowing down but im worried because iam running out of space

they have the growth spurt if ther first few weeks of flower and then slow down and energy is used towards bud production unless uu have a sativa which will grow a bit longer

ya two of them are sativas and there the ones im worrying about but thanks for the info thats wat i figured but just wasnt sure

Plants will double if not triple in size when they flower. Sativas moreso than indicas.

i know this is an old thread but i hope some one will still and answer my question.
during the growth spurt, GeeTee was talking about, do they create many more leaves (get bushier)?
the are a indica dominant strain LSD
because my grow space is very small i fear maybe a bit too small but i have no where else to do it, but i still want a half decent yield.
for instance if i put it into flowering at around 8 inches would it still give a decent yield?
Cheers

At 8"...hell yes! They should be transitioning for the first 3-3 1/2 weeks of flower. All transitioning means is "still growing". Also, it's funny how we call the stage before they're put into flower (12/12) the veg stage. If you ask me they hyper veg in the first three weeks of flower. If I put them in the room at 8" , by the time they're done with the transition phase they are about 3' sometimes more. Take into consideration that I run low pressure aero with 6x600w in a 72 sq. ft. room. The transition phase growth depends on conditions and strain tendencies. For instance, sour diesel stretches like a mofo no matter what the lighting scenario or growing method.
