Pleas help!

hiya guys. Im new to growing and this year has been my first ever grow. I recenttly bought some dutch passion power plant seeds. I since then germinated these by the end of may and well, wot can i say they are all at least 6 feet tall now and have been flowering for about 2/3/weeks.These plants have been grown in my dads greenhouse which is outside. I know i have to harvest them before the end of october or before the first frost sets in.

However what sort of yield can i expect from just 1plant that is roughly six foot. I would be grateful to know as nobody has told me so far. Cheers.

I have jus uploaded some pictures of my plant if this is of any help.
