Blog Post Here: https://university.upstartfarmers.com/blog/all-you-need-to-know-to-choose-a-hydroponic-design Whether you’re totally new or just adding on to an existing system, you need overview of all your choices. (Take an in-depth course on grow methods: https://university.upstartfarmers.com/courses/1030-choosing-your-production-model) But first, let’s review the basics of hydroponic design. There are 3 basic parts to almost every hydroponic system: a sump tank (sometimes split into one sump tank and one mixing tank), a growing container, and a pump. The Kratky method is one exception to this – it keeps the solution in the growing container with no pump and uses a measured amount of formulated solution. There are 5 main types of systems that use and arrange these parts in different ways: DWC – Deep water culture. DWC systems use a floating raft to hold plants over a solution tank. This is great for tropical regions because of the great temperature stability in the root zone but can have problems with dissolved oxygen levels. NFT – Nutrient film technique. NFT systems use a series of shallow troughs and are very common method in greenhouses on a single horizontal plane. It’s cheap to build up front but not very space efficient. ZipGrow – ZipGrow and other vertical tower systems use vertical planes to grow in 3-dimensional space rather than a single horizontal plane. These types of systems are more space efficient with lower operating costs, though upfront costs tend to be higher. Aeroponic – Aeroponic systems grow plants primarily in air, using a fine mist to deliver solution to plant roots. Aeroponics are cool and can be cost effective, but are a nightmare to manage. Media-based – Media based systems are any system that uses an aggregate or fiber media in a container. These could be media beds and Bato buckets are the two most common methods here. These are […]
