Hey Bean!
On your seeds... I keep mine in the freezer (with desiccant packs to absorb moisture) for long-term storage. I don't think you need to refrigerate in order to trigger sprouting, but I don't think it will hurt anything. Just want to make sure that they stay dry until you are ready to go.
Welcome to "practice-post" photos. Will be fun to see what you have been up to in the past. A suggestion that works for me. At the top of the box where you type in your comment, there are bunch of symbols. If you go over to the one that looks like a mountain, (next to the smiley face) and click on it, it will let you post photos directly from your computer at full size. The one you just posted above is like a thumbnail, and so readers have to click on it to see full size. Try another test, if you like, to see if you can post a full-size image. Other folks here on 420 are really good at the technology side, so they can help if you run into any challenges. Excited to see both your Chem and your Pineapple. Is a Pineapple Chunk or Pineapple Express, or...?
