Kenn, first of all welcome to the forum. I'm sure you can somehow make a blend with your homegrown tobacco that resembles Drum (the halfzware shag i think) but you'll find soon that there is much better to smoke than Drum... The tobacco used in the commercial blend is half flue cured and half dark air cured, plus lots of chemicals, preservatives, artificial flavours, umectants and God knows what else... Other members with more experience will surely help more than me.
