My First "Real" Grow

Have only been growing for about 6 months but this is first time with coco coir so starting out 25% and adding cal-mag right away. Also first time w/ feminized seeds from quality source so pretty excited overall :) if anyone has any suggestions let me know, otherwise I'll post weekly along with any experiments I like to randomly do. I have 3 going so far, so here's the first. ~~~~~~~~~~~ Seeds: Sink or Swim?! Summary ILGM recommends germinating seeds by placing into water until the tail begins to form. New to this method I'm interested in doing an experiment determine best chances for viability (primary observation) and growth rate (secondary observation) with sinking vs floating seeds. I'd think that seeds that sink have more water contact on surface area, therefore will germinate twice as fast, but it's also possible that seeds that sink will not have enough oxygen to develop, or become too waterlogged to germinate. Experiment - Place 2 ILGM Durban Poison and 2 ILGM Bergman Gold Leaf into separate cups with purified water, 7.6 pH - Purposefully sink one of each strain - Place in room with 22C temperature, no light Test Started: Saturday, December 7 @ 4:20 am Test Ended: Sunday, December 8 @ 8:43 pm Results All four seeds showed signs of a tail being formed but the two seeds that were floating were visibly longer (~1/4"), so may take more care not to sink them in future but it ultimately doesn't matter. All four eventually become sprouts at the same growth rate so sinking vs floating, though it's worth pointing out that it only took 28-30 hours to grow a tail is pretty darn awesome :) I don't know if that is genetics or this method, but will take extra care not to sink seeds in future so I can turn on my lights a few days sooner!
