SO many variables involved here... Container size, or in a prepared hole with soil mix, nutes, water, amount of sunlight, strain, etc... Ive seen ONE plant outside give ten + lbs, so, itz all up to you and the environment u provide for your plant or plants... Tangerine Dream is one strain that comes to mind for getting ridiculously large outside(and indoors), and will need to be staked and trelissed, as the weight of the massive colas can split even the sturdiest of stalks, and at the least they will need to be tied to stalks to support the weight that will be put on later into flowering...
