1. With standard WW seeds...I germinate twice as many as I need. Veg them for 30 days and switch to 12/12 flowering light cycle, to see who is boy/girl...:thumbsup:...(my last WW's; some showed the sex during veg (28 days)...the other showed their sex two weeks into flowering (12/12)

2. I like 20% perlite mixed into my soil, with extra drain holes drilled into the bottoms of the pots.
