I just finished manufacturing this 10 x 24 DIY greenhouse out of materials all purchased from Home Depot.
It was built around an existing system of 8x 300 gallon Laguna Tubs and a 100 gallon sump run by a 2.5 cubic foot Aquabead filter system with a 130 watt DIY uv utilizing emperor aquatic hardware.
There's still some finish work to do but it's enclosed in ready for winter.
