Wife and I started growing veggies in high tunnels a few seasons ago and are looking for easier ways to water. I was wondering if anyone else has high tunnels or hoophouse and use this Ro-Drip for watering. Seems like a pretty simple way to go, but am a little concerned about plugging and the fitration needed to avoid that. 

     Also I would like to know what spacing would be recommended for primarily tomatoes and bells.
