please help anyone

ive been growin a while now and cant quite get my head round a few things.
i got a few growing vids that ive downloaded which did help alot but wots buggin me is every grow vid they take there clones from veg room and put them in to flower at bout18 to 24 inces tall
and after 8 weeks the most theyve grown in height is 10 inces with great fat buds on the end of them. now ive tryed waitin till there between 18/24 inces and they grew about 30 incs in 8 weeks buds were ok but not as fat as theres

so the next grow i tryed flowering sooner i waited till they were about 8 to 10 inces thinkin they would stay small but they still grew about 2 1/2 feet buds about the same size whitch was ok if anyone has seen the green man vid i grow cronic and knows how he kept the height growin to a min and the buds growin to the max and can let me in on his secret i would be well happy

it's all about the roots hon... spend most of veg concentrating your efforts on building roots. if you have clones, then they are female; no fear of males from high phosphorus nutes. feed mostly with root stimulator or flower ferts. supplement with nitrogen based fert two to four times in eight weeks.

i have some moms in flower. they are monsters now, and only half way through; at least a qp ea.

not sure what your question even is are you using clones are growing from seed?
roots, nutrients, strain used are all important to good growth however the amount of light is also a big factor in producing larger buds once you have the basic stuff covered.
