Hey Tokalot,
Sorry to hear you lost 4 BBs and only got 1 of 5. I know its a little different, but maybe you might want to try a different approach next round. I get 100% this way just about every single time:

1 - Skip the nute soak, paper towels and all that shit
2- - Fill large cup 1/2 way up with ferted good draining soil mix (organic or chem)
3-- Fill second half with store bought seed starter soil and a little extra perlite
4. Wet down good, let drain and put the seed in center on top
5. cover with 1cm seed soil and spray w/ water until good and wet. cover loosely with plastic wrap.
6. Keep about 75 F and wait. Seedligns usually come up in 24-48 hrs. As soon as they begin to break the surface, get rid of the plastic and get them under the FLs.
7. Do NOT water again until cups are getting totally dry.

As far as nutes the soil in the bottom half of the cup has nutes and the roots will get there quick enough. It will hold them a while. After maybe 1.5 - 2 weeks, hit with a half strength feed.

Give it a try some time. Maybe just 1-2 bag seeds for an experiment. I think you will find it much easier and more reliable than the soaking and towels and such. Works every time for me. Have not lost one in yrs.
