Hi welcome to the pleasure and rewards of brewing your own, trust me you can make some very nice beer with a bit of patience using the knowledge that abounds in this site. I started about 8 months ago and have had comments such as "if they sold this in bottles I'd buy it". I use both liquid and dry malts, bit of dextrose, corn syrup powder, some crystal or cara grain and a little wheat malt and cooked up pellet hops.
If I were you I'd use the hops availabe in pellet form to find the flavours you like. You could start by using a pre hopped can (Coopers mex, Can blond, Aust ale etc etc) and boiling up some different hops in the water you rinsed the can out with for 5 minutes or so, this can really improve the basic goo can. Don't use sugar use dry malt extract, chuck the yeast packet that comes with the goo away and pay about $5 for safeale S 04 or similar. Temp is also a biggie don't let the fermentation get above 23 - 24 max max 0C, constant 18 - 20 is good
I wouldn't worry about growing hops just yet, you may find out as I did the flovours and aromas I like dont like my climate (WA). I wll eventually grow some but probably only bittering hops. Concentrate on developing a good beer style using what's available and your creativity (with a little help from Ians spredsheet). If you keep everything clean, have a bit of patience and be prepared for the odd flop that you an learn from then you will enjoy brewing.
Cheers, most of your foreseeable questions have probably been answered somewhere on this site but dont be afraid to ask,
Have just read your posts on partial forum, It's not just growing the the barley, it has to be malted, an art in itself. Guess your going the organic/sustainable route. Wow. Good luck and hope you get there.
