I can recommend two strains from personal experience: Diablo - no idea who it was from, but I can find out if you're interested. Actually, I am going to find out anyway, because I want some for next year, and I'm already hunting for prospects. 2nd week of September in Nova Scotia, if memory serves, so a worse climate than yours, and I wouldn't say amazing yield with the effort I put into it that year (which wasn't much), but in a full bail of VPW30 with a feedbag of 2-year composted cowshit, plus bone and blood meal (separately) right in the mix to begin with, and an initial and two subsequent feedings with water soluble 20:20:20 (just sprinkled on dry), I would say you could probably pull a half pound off one, at a minimum. But...watch em for mold. They don't like it. However, I grow in a swamp, so the humidity is even higher there than usual in my climate. But I can say that it's worth the time. Dense, and seriously fucking potent. I'm no kid, and I been around for a long time, and don't associate with kiddies. My one buddy nicknamed it 'the mule' because he said it kicked like one. It did. Also, Mandala #1 from Mandala seeds. Again, wasn't a heavy yielder with the efforts that year - about the same as Diablo, and I figure you could pull off about the same as that, under the conditions I described above - but again, an early finisher. No, not August, and definitely not July, but early September. And that is in Nova Scotia, so worse than where you're at. And very nice quality. Pleasant tasting and smelling, and also cheap. I'm going to ask Mike at Sagarmatha if he'll divulge what the strains were in the Magical Mystery Mix #1 packs Gypsy Nirvana was giving away a few years back, because there were three strains in that that were utterly fucking amazing, and all of which finished here. If you're interested, lemme know, and I'll pass it on if I find out.
