Bucket hydroponic systems are the easiest way to get started with indoor gardening. Using 5 gallon and 3.5 gallon buckets, HTG Supply has created simple and affordable hydro systems that require minimal maintenance and upkeep. By utilizing deep water culture, also known as DWC, …techniques your plants roots are constantly suspended in an oxygen-rich nutrient solution. Plants in DWC grow faster and get bigger than their siblings in soil, as their roots can constantly uptake the water and nutrition they require.
