I recently saw a thread here where a plant was badly burned from using cs, but it did work. I'm going to start brushing cs on one branch next week, you can watch in my journal (link in sig) if you like. I'm planning to only brush one branch, and watch it closely, and hopefully snip it off to collect pollen before it pollinates anything. Then use the pollen to pollinate only one bud on the same plant (blackberry from nirvana, because it's my biggest plant, has the most branches). This might not work out like I plan, but that's ok, gotta learn to produce seeds to create my own seed collection and save money. I hope to do this with a girl scout cookie before the end of the year as well.
