I wouldn't go by float or sink method. I tried it in the past. Last time, I had both sinkers and floaters take. Just soak em all overnight in water and drop em in shallow, low or no-nute potting mix. I poke a fresh eraser tip into the dirt and use that as my planting depth. I've only had one dud seed in the 6 or so grows I've now done. Good genetics from reputable seed banks I find is key.


No matter what method or how much care you take, it's touch and go until you're seeing healthy green cotyldons unfolding.
