Well thanks, I'm flattered.
But as I have in my signature, I have no formal education in plant science so I'm just relating my experience over the last few years. Nothing is scientific. I'm just a dabbler in plant breeding but I find it fascinating. Besides cannabis I have some projects going with vegetables and flowers. It's a long process and I'll likely still be fiddling around making seeds until the day I die. I'll probably be laying on my death bed not thinking about dying but how that last cross turned out.
Out of the 2 PCK phenotypes the green tends to be more resinous and potent. I also thought that it had a better taste and smell. The first time I grew it was a pack of 5 fems. I ended up with 4 purple and 1 green. When all was said and done I preferred the qualities of the green over the purple. The taste, smell, and effect just seemed superior to me. Don't get me wrong. The purple is good but I prefer the green better. To me something just seems missing with really colorful weed.
