I know folks that grow specifically for foxtails. They call it crowning the buds. They are into hash, honey oil, live rosins, process and press life in general.
Of the two Purple Haze one was harvested after 10 weeks. I also harvested it in two batches. Top buds and lower buds at week 11. I have smoked the first plant for about a week and I like it. When curing is complete it will be a good one.
I have always been too eager to harvest. This one seemed slower in maturing than her sister. And the Foxtails caught me searching for an answer to it. I’m harvesting it now. These buds are huge.
I read too that some people like Foxtails and I will have to try some alternative uses if smoking doesn’t work out.
