I tell ya, I as a beginner grow, mostly, I bout four months ago really accidently worked at killing seven ww seeds, I mean, first I didn’t put enough work on one seed that didn’t put out a tap root after 24 hours and peat pellet planted it, never worked, and I suspect I could have paper toweled it to view a tap root, not just crossing my fingers for seven days. Later I drowned three seeds after sprouting in water 24hrs, in peat pellets, and three more I put cold fan air cooling them off till dead.
36 years ago I was good at paper toweling seeds set next to a tv in foil(which is why I could check them two days or more later and find success), I had almost forgot that use of foil was a great way to keep them moist, and I was a kid back then, so I did two super skunk female seeds(ILGM bought of course) this week successfully immersed in water for 24 hours not seeing a root yet, half of that time with a acquarium bubbler oxygenating the water to be “safe”, so I then moistened a paper towel, not soaking wet, just moist, then took a piece of foil with the middle puckered up like a pup tent to provide an air space, and put the seeds in paper towel inside the foil, but I went further in a zip lock bag, and under a t5 lamp that was keeping everything 75 degrees. I checks 18 hours later, and wow, the two tap roots were burst out very very long, almost too long, was like a quarter inch long,planted them two seed lengths near the surface, where previous I obviously went too deep on unsuccessful starts.
I probably went overboard, maybe, next time I think I will use the bubbler in water the full 24 hours, to be safer. I wanted to paper towel them, cause I too waited about a week after planting some seeds months ago only to figure out I had killed some seeds that hadn’t grown hardly a tap root at all.
