Quad Cookies - New Strain

This is the first plant of a new strain I created last year that I've been calling Quad Cookies (seeing as it has Thin Mint Girl Scout Cookies in all four branches of its family tree). I didn't take photos of this one until it has started to flower, so skip ahead to Week 3 of Flower if you like. Went with soil - in 2gal pots. I didn't have any good soil, so I just mixed Miracle Gro, seed starter and perlite. Yes, a terrible substrate, I know. But, hey, I didn't want to lug home a 50lb sack of good soil... 2 gallon pots because I didn't want her to grow too big. Expecting maybe 150g or so. Not a huge amount. Just want to try it and see if the cross is any good. The cross is: Strawberry Iced Creme (Ice Cream Cake x Strawberry Float) x Pink Tourmaline (Pink Runtz x Cement Shoes). Photos are of the actual mother and father (they were grown for seeds, so they are only in pots that are around 1 pint and 1 gallon, respectively). Of course, the 'father' is a female that had a single branch reversed. It almost didn't work too. After spraying that branch for a month, I only got one male flower-cluster with only one viable male flower - and, when I opened it up, it appeared empty of pollen. Now, cannabis pollen is pretty small and hard to see, but it sure as hell seemed like there was nothing there. I grabbed a paintbrush and pollinated the females anyways, just in case there was some pollen in there. And it worked! The first plant I pollinated was actually well-pollinated and produced tons of seeds. However, the other plants not so much... One only created one single seed - and another one only created two seeds - on the entire plants!
