I am going to be growing tomatoes this summer and will be gone for weeks at a time. I have rigged up an automatic watering system but have not yet figured out a way to prevent hornworms. I will not be home on a daily or perhaps even weekly basis to pick off any hornworms before they do major damage. Has anyone ever tried using mosquito netting or think this is an effective way to prevent the hornworms? I live in Texas so I'm not concerned about diminished sunlight at all.
