I am so excited to say I just ordered 24 of these cool alternative to the flimsy Wall Of Water. Now I am sure the Wall of Water is a great tool for many gardeners, but it did not work well for me. The reasons it failed are named Barrett and Marley. Two funny black labs that thought it was a handy drinking fountain. Not so funny. I have to purchase my tomatoes and peppers every year. I have run tests with tomato plants with a wall and without a wall around it. Where we live, I have to purchase earlier than I should plant for our area, but if I don't the plants won't be available in the closest shopping mecca. Their season starts at least a month to 6 weeks earlier than ours. I usually end up covering my tender young plants at least 3 or 4 times before the absolute last frost happens here. They don't grow even a 1/4 inch when not protected by a water wall insulator. But with one, they grow great. (Except for Barrett and Marley.)
These domes are hard sided, 16" tall and have a two wall system to add water to. I have read that they should be stored out of the sun when not in use as they may become brittle. That won't be a problem for me. They are from a company called Winged Weeder who also has fabulous tools called Winged Weeder or Winged Weeder Jr. sold by Do It Best. The Aqua Dome cannot be purchased from this company but when I called the company, they said you could purchase it through several farm supply places we don't seem to have in Idaho. I spoke to Kirk, who was very helpful.
Let me know if any of you have tried this cool wall before. I can't wait to get them. Now I won't worry nearly as much as I have in past years. I love garden gadgets.
