@WMoon518: No data at all that I could find. I only know about it from either this thread or one of @Mr.Sparkle' micro grow thread. I ordered the small size. If it works like people have said it will, it is worth the cost. That said, if it works, I'll try making my own, then if my own STS doesn't work, I'll know I got something wrong in the recipe.
I have no problem with regular seeds. I really do like femmed seeds though, every sprout is a keeper. My largest reason for getting STS is that I got at least 3 strains given to me that were femmed seeds. One of those is known to be very difficult to pop. If I like the weed, I'll want to be able to grow more. I've had great luck turning a branch into a herm in the past to get fem seeds but putting a black cloth bag on a branch for an hour or more. But, I found out that after I kept generating new fem seeds and not keeping the old ones, it seemed the plants got resistant to creating a herm. This then requires some pollen for seeds.
My goal is to not let anyone's generosity be wasted on me. I want to generate plenty of seeds from my gifts. I intend to pay it forward when I have them. Gotta keep up the tradition.
@Kelly, I wasn't able to find one. If you go to eBay and search for item "The Need For Seeds" It'll come up as the first 2 items in the list.
