I love growing sativa indoors. sativas always seem to come out better where i live. My grow room gets hot! Whenever I grow an indica the calyxes stretch and the bud comes out really loose from the heat. Everytime I grow trainwreck (cal clone) it comes out amazingly dense. The plant stretches like crazy at least 3 times in size. After about week 10 I notice some male flowers popping up but it makes it to week 12 without any seeds. I saw super silver haze at a dispensery here in So cal. I was thinking about growing it. Your plants look very similar to the trainwreck I grew. My favorite way to grow trainwreck is scroging it. I just did that for my first time and it came out great. You might notice your branches having trouble staying supported late in flowering. Some yoyo's will fix that. I will be interested in following your grow and possibly growing haze next. I really want a pure haze but the super silver haze at the dispensery looked amazing. I love sativas.
Your plants look great so far, I look forward to seeing there progress.
here is a link to an old picture of my grow.
