This was super easy to put together and set up. I was afraid the pump was too small, but it has been working perfectly for about 3 months . The timer is great, and also works perfectly. The only thing we added was a fish tank pump to keep the water clean, and a rubbermaid 8 gallon plastic bin from Walmart, and some grow lights. We have been growing spinach, romaine lettuce, and strawberries. We are beginners with growing hydroponically, and this is by far the most simple way to start learning. It does all the work for us too
