High altitude school of hydroponics is a great company. They have a wide range of courses and resources for anyone interested in learning about hydroponics. The instructors are knowledgeable and passionate about what they do, and they are always willing to help students succeed. I highly recommend their programs to anyone looking to expand their knowledge in hydroponics.
