I had my question answered about watering issues so I wanted to say thanks a lot for the help! I'm pretty sure it boiled down to my husband watering in the wrong way.

I still am curious about new watering techniques though and I wanted to start a new thread to get some opinions. I keep reading about using this SpraySmarter teejet but I still want to know if it has a shower setting. Not necessarily just for the milkweed but other plants in the greenhouse. Let me know what you know about it.
