I've collected a bunch of cotton from my 3 cotton bushes, which are about 4 feet tall. The bolls were a bit scrawny, I think I need to give them more feed. I've been feeding them worm tea and organic power-feed. I removed the cotton from the bolls, these still have the seeds inside. There's 46g in this first bunch. I guess when I collect a bit more I will separate the seeds and give it a spin. Yet another thing to learn!
