Them cats only move up or down don't they. I was looking at the directions for BT and it actually says to apply from 3-10 days so you could be right about the sun breaking it down in a day.sorry to hear your troubles shangri-la. I'll be interested to hear how you think this affected your overall harvest when all is said and done. good luck.
that is the plan I have been on , racer. i started about half way through the stretch. so far zero caterpillars found. we check every day by pulling the buds back off the top colas.
i am a little paranoid, though. every morning there are wispy little silk webs from bud to bud on many colas. must be from spiders. no rot... no dead looking leaves... no preponderance of cat poop... could I be missing something.
