How much shouls i expect to have?

How much would a sing plant about 2 or 3 feet tall and 2 or 3 feet wide like a bush, how much should one expect something like that to make? a ounce or so?

well... you long was it vegged? indica or sativa? what kind of light? what kind of nutes? what kind of growing medium? Your question is a bit like asking how long a piece of string is.

a 3 by 3 by 3 plant (super bush) should give you between a qp and a half pound, if yo are an experienced grower, actually maybe even more. I've never grown a plant that was as wide as it was tall... thats all speculation. I've gotten more than an ounce out of 2 foot tall, 1.5 foot wide plants before.
