When should I Flower?

I was wondering when should I start to flower my plants. I would like to get about 4-6oz per plant and they are about 2ft tall now. I heard that when you move them to the flowering room they can grow 2 to 3 times larger than when you first put them in to flower. Can anyone give me an estimate as to how much I can get for different sizes of the plant.

Like how much could I get out of a 1ft, 2ft, 3ft, and 4ft tall plant. I don't want to grow them too large but I would like to get enough out of them to last between harvests and maybe have some left over to give to friends.

Anyone have some sort of idea on how much I could get out of different sizes of plant. I don't plan on using any blooming nutrients or formulas. I only plan on using molasses and water.

it really depends on the strain of plant....

Hmm any guess then? Like an average amount you'd get.

ya just like nick said it all depends on he plant and how well you grow it (nutes, co2, lights, etc)
