I wanted to dive into hydroponics in the cold winters here to grow some fresh produce.
This project was inspired by Mary and Joe's youtube channel so please go check them out to see a video of there setup.
Started with some 1.5" pvc tubes, a few wyes, caps, elbows, and sanitary tees. Lay them all out and glue them together with some pvc glue. I used the gorilla glue brand that self primes. It seemed more food safe. Each vertical hole and diagonal hole is about 8 inches apart. If I did it again, I would space them about 12 inches because everything gets so big so fast. I did not glue each tower to the sanitary tee so they could be removed for cleaning. I also did not glue the cap on at the top.
Drill holes into caps and put in irrigation lines. I made the holes at a slight angle so the water could hit the hole side of the pvc and run down over all the roots.
Back side with water reservoir, pump, and optional spigot. The spigot has been awesome for adding nutrient water to random other plants or Kratky setups. Both elbows are not glued so you can rotate the drain pipe up to take the lid off the reservoir.
Tried to see if PH levels vs tap water, vs melted snow water affected growing outcomes. Differences were minor.
