so if all the plants i planted r from the same bag seed r they all gonna be the same type of weed i hope some one understands me ..........
Not necessarily. There can be variations in hybrids after the initial cross pollination. For example: NL#5 x Haze: The first pollination will yield mostly identical plants (f1). Next batch of seeds from pollination (f2) will start to show different % of dominant and recessive traits, ie a mostly NL#5 or a close to purer Haze. Careful breeding can eliminate this eventually with a nice stable inbred line (IBL). Some strains will never be stable though. Almost forgot your question: In general they will be similar. Hope this helps
