bah humbug. LOLOL~ I never buy fem seeds. no offense, but I truly believe it is all in the way you handle them that helps to determine the sex. Call me crazy, but I always get very high fem ratio, when I use new genetics.

One word: Superthrive

Read up on "Henk" at *Dutch Passion Seeds. He feminizes seeds, and he has an article about how to-light schedule..."14-16 hours of light with 8-10 dark always yields a higher % of fem's."

* Dutch Passion seeds are one of the most sought after in the industry. "Blueberry" ring a Bell??? Well if you want "real" Blueberry...

Anyway. I never towel germ'. I believe the less handling/stress the better...
I plant in anything that allows me to never touch the plant again...

4" pot filled with a sterile hyponex $ store, wally's soil, perlite, & Peat.

Jiffy Pellets (easiest on earth, (if you follow directions),

Rockwool (hated by some...loved by the rest).(((Love ya' Z))),

Oasis (what We all use on the commercial hydro-farms).

Have fun! Peace
