Trout River Aquaponics offers this 'Economical 4x4 Wooden' grow bed to help those who would like to grow safe, healthy vegetables, and fish. The Trout River books are well illustrated, are loaded with step by step instructions. There are so many designs online but, we found many of them to be poorly illustrated, complex designs that often fail. Our goal, like many other families is to grow our own food in a safe, healthy and organic system that is cost effective. Our, Trout River Aquaponics Systems books have clear, concise and easy to understand, step by step instructions, and we use each of these systems 24/7 in our own family garden. Visit our Facebook page for examples; Trout River Aquaponics. All of our systems are in Raised Grow Beds, no more down in the dirt weeding or planting, Everything is in raised grow beds, no soil, no weeds.
