How much does the plant grow during flowering?

[DJMello]

I have limited space, so I can't let it get too big. I heard they double in size, is this true?

 

[phyzix]

It is true. Sativas stretch more than indicas though.

 

[BOOM WHOMP]

depends on the strain but double in size is pretty common

If you flower at 10 inches, expect the plant to reach 20-25" (more if sativa dom)

yea some dub and some triple in size durring flowering. I just copped a hortilux w. enhanced spectrum with more blue light and just enough red to promote flowering. Guy told me it will bud nicely and witht the exta blue spec will make denser less stretched nugs so a new light could help you too. Topping them or LST can help you out in reducing size of a plant also
