It's only a few weeks old. But I stuffed up and played with high EC levels a few days ago before going away for work. I'm new to this, so no idea why I experimented and didn't go by recommendations on here. I've have mixed results from Attitude (took ages). And some othe mob in the UK (took ages and can't remember their name sorry). ilovegrowingmarijuana was real quick and had tricky stealth.
