Growth in flowering stage

I have somewhat limited space and was wondering how much taller a pot plant usually gets when flowering? I plan on flowering when my plant reaches around 20in

From my expierience, they almost double in size.

most indica double in size,, hybrid and sativa tripple or 4 times the size....... it could go to 5 times the size is u stretch alot.........

what height do u have to play with.. usually u should put into flowerning at 8in.... sativa 3-4 in

lol....uh.....my tallest is 17in. Ive been doing 18/6 light cycle for about a month straight now. However my plant is extemely thin, it has a nice stem and holds up good but when I see pics of others there plants are WAY WAY more bushy looking then mine. Bushyness is nonexsistent on mine....is this because its in vegatative stage and not yet flowering?

Advice.....start flowering?!?!

Your lack of bushiness is probably bc of your lights. R u using cfl or something?

Ya.....the actual light I used to get my plant to the 16-17in mark was a shitty 150w incadescent single bulb! Cut me a break im new, lol. In fact I just today bought a new lighting system. I am now using (2) SunBlaze T5 Florescent high output strips. My model is 24in long, 24w and 2000 lumens a piece. i am expecting alot more from them then the crappy incadescent. What do you guys think of the new setup?


Also back to the original topic....I think I have decided to start flowering on my 17in plant due to limited space.

Check this photo out, I believe someone said it was a sativa. This is exactly what my plant looks like without the hairs and such around the nodes, its stretched looking, not bushy.
