Squid-They are called "The Green Pad Jr." and essentially they are little pads that release Co2 in humidity domes. They are activated by the humidity. Like I said, I didn't order them, got them as a freebee when I ordered up a bag of natural Co2. Pretty cool.
Bean-Thanks for posting the pics! Hope your good luck rubs off on me. I did the old paper towel trick until the seed cracked and I saw the tap root show (took about 36 hours) and then put her into a jiffy pot with jiffy seed starting soil on Thursday, this time around I used a humidity dome with a heat mat. And hot damn I think I saw a little something something start to poke through on Sunday! Gave a does of water yesterday. Hoping it all works out this time. Good luck on the rest of your grow!
