In this video I put together the start to finish grow of hydroponic carrots. The carrots are grown in a 5 gallon bucket with a propped up 5 gallon paint strainer. The paint strainer was filled with Rock wool. Irrigation was just a 1/4 in. tube run by a pool pump in a nutrient filled container. The pump was ran on a timer set to come on for 15 mins every hour. A drain pipe towards the bottom of the bucket allows excess water to flow back to the container for reuse. Time from seed planting to harvest was approx 70 days.
