Works great. I use this method only on my ID tomato plants. The determinant ones I just homemade cage. When I plant I always lay the plant on it's side and bury 3/4 of the plant sideways leaving only the very top of the plant out. This makes a better and stronger root system. As my ID ones grow I keep adding the horizontal strings at the bottom being sure to weave 2 at a time in and out alternating the strings to be on each side of the stem. I take off quite a few leaves near the bottom as the plant grows to help with production along with taking the suckers off. I stop my Horizontal strings where my leaves begin. If my plant splits I try to single stalk it by selecting which stalk will be a better producer. I then untie the top of the string and keep (Training) or wrapping the tomato plant around the string carefully as it grows. This method works very well for me and holds the plants great while not restricting the plant in any way. I have always ended up with way too may tomatoes to eat and give loads away.
