The main difference between drip tape and drip tubing is its thickness and sturdiness. Drip tape is a lot thinner and more flexible, meaning it's ideal for short term irrigation, but doesn't have the same strength or longevity as drip tubing.
Drip tape and drip tubing are very similar drip irrigation supplies. They are installed in the same way and only have slight differences. Physically, although they almost do the same thing, drip tape is much thinner and more flexible.
Because of this, drip tape is much less permanent and weaker than drip tubing. Drip tape is usually found in temporary or semi-permanent irrigation systems, like in the garden of a renter, for example, where they don't want to commit resources to a short term garden. The thickness of drip tape is much thinner as well, making it a poor choice for homes and applications with a heavier flow of water or water with a higher PSI.
Inversely, drip tubing is much more stable and permanent. The thickness and strength of the tubing is much more formidable. It can handle higher PSI flow rates and will last much longer. Drip tubing is installed the same way as drip tape, and drip tubing can even replace drip tape in the same system. However, if you know you are going to be committed to an irrigation system, it's often best to go straight to drip tubing and cut out the hassle of drip tape.
