Trainwreck Grow! Help Please

Ok i am growing a trainwreck plant she is 16 inchs tall in veg ive topped her enough to have 10 colas. I want to put her into flowering but i have a small fence out back i want to know how tall it will grow wen it flowers because ive herd it can triple its size

do you have pics cuz im growing that strand and wanna compare?oh n yeah heard it doubles its size at least.

Very rarely will a plant tripple in size while flowering, and having many colas it's even less probable. It'll grow taller while flowering but not that much, how much will grow depends on the pot size, light and other factors.

I'm not understanding the question, are you concerned someone may see it? You can always LST it even if it is a outdoors plant
