According to GD, the paper towel method has 100% success rate without user error. IME, your water source, medium source, and container source are all critical. Using a paper towel roll from in the kitchen or a napkin from a store? absolutely never. using some top shelf virgin cotton sealed as sterile in single use package imported from japan? sure. using water from your 8 stage filter or from the tap? never ever ever. Using bottled water guaranteed sterile? sure. Using a baggy from the kitchen drawer? nope. A box of baggies for seeds only in a sealed bag that you never open without a full wash then donning gloves. These type of improvements on the paper towel are where anyone can get the 100% success rate.
I do get a bit over the top when I am popping something rare or valuable, but I greatly prefer popping in a cup of water and then manually placing the seeds into rockwool, tease the tap out of the cube with a heater, then right into hydro for the rest of forever until she is gone...whether that be a week or three years
