I grew +150lbs of indeterminate tomatoes, +50lbs of cucumbers, and several quarts of beans in around 40 buckets last year. This year I've upped it to almost 90 buckets (still about 10-15 short) and added 3 planter boxes for onions and potatoes. I run everything through a fertilizer injector and drippers (still setting the irrigation up, just laid it out to see what I'd need to cut/change) I'm hoping to grow enough to supplement half my food intake and trade with the neighbors.

I've got a 2015 drz400sm, I have both SM rims and dirt rims which I think are 21/18? I tried to put the 41t rear sprocket from the SM on the dirt tire rims, but the sprocket holes didn't line up. I'm looking for a 38t sprocket for the dirt rims, but I don't know where to look or what model the rims are technically from. Any help?
