I've found the perfect way to keep track of my plants. I used to always use a piece of tap with the name of the strain written on it and stuck it to the pot, or those little poke in the ground place markers. But I had problems with the place markers getting blown away and the tape didn't work well because it didn't stay with the plants when I transplanted. Now I cut the top rim off a foam party cup and slide it around the stalk of my plant while it's still little. It can't get blown away or knocked off, and it stays with the plant when you transplant. Just thought I'd share this simple tip because in past seasons I had some problems with strains getting mixed up.
