I have all versions, and haven't had any luck with any of them. I know some people have great success with it, I just wish I was 1 of those people lol. I thought it was just me, but I see others post that they have major issues too. I will miss it's simplicity, but at the end of the day I want to grow big sticky girls like I use to. This is a results business, and these results ain't cutting it. I'm not throwing it out, or anything. Once I can grow more than 2 at a time I'll experiment with it. See if I can find the right combo. I can't have more of these grows. I'm doing a photo Malawi next grow so looking at a 4 month grow. This harvest ain't gonna last that long. Yes in the US.
