Dutch Bucket Hydroponics – A Full Guide

Introduction: Hello gardeners today we are back with a very good information of Dutch Bucket Hydroponics. Dutch buckets are one of the popular ways to grow big plants using hydroponics. They are affordable, versatile, and reusable and are easily connected together; making a Dutch Bucket system endlessly expandable. They can be used with a large variety of different growing mediums, whether filling the whole bucket with hydroton clay pebbles or using lids with 4 inches net pots.

A step by step guide to Dutch bucket hydroponics

This is a variation of the Ebb and flow (or Flood and Drain) method. It differs in the way it looks, but still, operates on the same principle and the nutrient is forced onto the bucket (that replaces the tray) then automatically drains back to the reservoir at regular intervals. The Dutch Bucket is, by all means, an effective yet easy to set-up for any indoor hydroponic and outdoor hydroponic growers. It can be used as a Hydroponic system and works great for aquaponics as well even though it is harder to set up.

Dutch buckets offer the greatest versatility in growing different plants due to its customizable features and flexibility in arrangement and can be used for both hydroponics and aquaponics. Dutch buckets are an easy, approachable way to begin hydroponic (or aquaponic farming (although aquaponic Bato systems are more difficult). Building a Dutch bucket system is simple, inexpensive, and easy to operate at any scale. In this article we also cover the following topics;

• Dutch bucket design types
• Plants for the Dutch bucket system
• Bato Bucket Hydroponic System
• Dutch bucket hydroponic system working
• Optimal pH for Dutch bucket hydroponic system
• Growing media for Dutch bucket hydroponic system
• Mistakes to avoid while growing plants in a Dutch bucket system

Different variations on Dutch bucket hydroponics design

The design of Dutch buckets systems is simple, with multiple variations on irrigation and equipment. A reservoir pump runs particularly formulated nutrient solution through a straight line over the buckets. Drippers control the flow to each bucket, and the solution runs through the media and drains out of the bucket. And each part of the system has variations to suit grower needs.

The number of buckets – To build a larger one-line system, growers can use a larger reservoir and pump, longer irrigation and drain lines, and simply set up the system the same way as the system below. For growers who wish to build a larger multiple-line system, we recommend going through the Dutch buckets course first to familiarize you with the technique.

Media type – The most popular Dutch bucket media is vermiculite, other media like hydroton or crushed granite may be used.

Minor components – Many components of the system like tubing, drippers, fittings, and clamps can be sourced from a home and garden supply store. The components that growers will probably have to order online or from a specialty store are the major reservoir, the buckets themselves, and the pump.

Build a hydroponic Dutch bucket system

• Cut PVC down to 8 feet or length of the table, leaving room on the end for the end cap and elbow. Make sure this fits on the table.
• Put the Dutch buckets on the table and decide on spacing mark the placement of the drains for each bucket on the drain line. By using a drill and a 1-inch hole saw, drill out holes on the marks.
• Use primer and PVC cement to attach the PVC endcap and elbow, make sure that the elbow is facing downward while the holes in the PVC are facing upward.
• Drill holes in the table on side of the PVC to attach zip ties and hold the PVC in place. You could use a 1.5-inch conduit clamping here instead of zip ties. Run the 1/2-inch tubing along the middle line over the buckets, and fastening it in place with clips or clamps. Leave a few feet on the end to reach the pump in the reservoir.
• By using a 1/8-inch drill bit, drill out holes through the ply tubing on either side of the clamps. This is where we will put the drip emitters.
• Then, cut the end of the irrigation line and add the release valve, which is good for flushing the system and draining the reservoir. And fasten it with a pipe clamp.
• Cut 16 5-inch strips of the 1/4 inch tubing with attaching them to the drip emitters. These will center irrigation to run directly over the plants.
• Attach the end of the tubing to the pump and then fasten with a pipe clamp. Put the pump in the reservoir. Test out the hydroponic system and make sure that each drip emitter is functioning and no leaks appear.
• Then plant your crops in the media. Choose a combination of perlite (the most popular filling) and hydroton (which keeps the Wyoming wind from blowing away the perlite).

Working of Dutch bucket hydroponics system

First, you would notice that there are several buckets on the bench or table. Each bucket must only accommodate one plant. These buckets should contain growing media (perlite, vermiculite, etc) to keep the moisture, aeration as well as supporting plants to stand upright. There is one large bucket or reservoir that holds water and nutrients.

A submersible pump is placed into this reservoir to pump the nutrients onto the drip or irrigation line and drop onto the plants via the drip emitters. The drip emitters are fixed to the drip or irrigation line and are pointed to each bucket to feed the plants.  You will see the bucket elbow at each bucket. It functions to drain the excess nutrient solutions to the return drip line and then come back to the reservoir. As a result, and nutrient solutions are not lost during the watering, and feeding procedure, making this method an effective recirculation technique.

You can turn on the pump and let it run 24 hours a day without stopping and regular checking. This is because when the pump gets the nutrients and water onto the drip line, buckets, gravity will drain it back to where it begins. If you don’t want the nutrients to return to the reservoir, you can get it to drain out of the system and this is called flow-to-waste. As it is wasteful, it does help solve the problem of nutrient unbalancing. Over time, plants will take up some main nutrients, creating an unbalance of nutrients in the system. Nutrient unbalancing is not good for plant growth.

With good set-up for the amounts of nutrient solution from the drippers, growers can let the system run continuously without worrying about drying out and suffocating plants. But you’ll need to check and change the nutrients of the reservoir at various intervals. The frequency of mixing, diluting the nutrients in the reservoir is dependent on the plants or bucket numbers and the reservoir size. A digital timer, this is connected to the pump, can be used if you want set intervals for the flooding circle.

Different ways to run the drainage system in the hydroponic system

There are two ways to run your drainage in Dutch bucket hydroponic system;

• Flow-to-waste and
• Recirculating

Flow-to-waste irrigation

Flow-to-waste drains solution out of the system. This option is wasteful but much simpler in terms of nutrient balancing. Nutrient balancing mainly depending on the crop and its age, plants will take up unique ratios of nutrients. Younger plants of one crop might take up more nitrogen than older plants and plants that are growing fruit might take up more phosphorus, etc.

Although fertilizers are formulated to fit the crop, there are still minute differences in the ratio of nutrient to a nutrient in the fertilizer and the ratio of nutrient to a nutrient that the plants use. This means that over time, and a solution can become unbalanced; one nutrient could accumulate while others are used up. This can lead to deficiencies and less often toxicities.

Recirculating irrigation

The more conservative drainage option is to run Dutch buckets on a recirculating system. In a recirculating irrigation system, the buckets are irrigated and drain into a return line, a PVC line at a tilt that brings water back to the reservoir for reuse.

Growers using recirculating irrigation systems can avoid nutrient imbalance by replacing the water every few weeks (this saves water and nutrients, cast-off water can be used for other garden beds) or by balancing nutrients individually. Balancing water nutrients individually involves getting a periodic water analysis to verify the levels of each element in the water.

Growing media for Dutch bucket hydroponics system

The buckets should contain growing media (perlite, hydroton, and coco peat, etc) to keep the moisture, ventilation as well as supporting plants to stand upright.

Perlite

It is a natural filtration system, by allowing excess water to simply drain away while retaining a little moisture and catching nutrients that plants want to grow. Airflow in the soil is greatly improved in a bed amended with perlite, and that’s essential both for your plant’s roots to breathe. Because it’s mineral glass and harder than the soil around it, it also helps to slow down compaction and keeps soil fluffy and lightweight.

Hydroton clay pebbles

Extremely stable in both pH level and EC. It is made from 100% natural clay. Strong structural integrity means that they are less to break and compact, which helps to prevent dripper systems from getting blocked. It drains freely and does not hold any excess water, providing oxygen levels around the root; appropriate for flood and drain systems, multi-pot and drip feed systems.

Coco peat or Coco coir

Coco peat is a renewable media and is extracted from the husk of coconuts. Coco peat has natural Trichoderma which acts as a Bio agent against harmful pathogens. It provides a great environment for useful fungi and bacteria to grow. It can be pressed into a different variety of shapes and sizes to suit all growing applications.

Components of the Dutch bucket system

The Dutch bucket system has the media where the plants grow, and you can position them to offer the plant spacing wanted for the plant being grown.

Many features are incorporated into this system design, which let them be the central part of every plant and grower-friendly system. Bato Buckets sit on a drain line created from a 1to1/2-inch PVC pipe. Dutch bucket for sale feature holes, which are drilled in the irrigation line to fit the Dutch Bucket’s drainage nipple. 

Different plants for Dutch bucket hydroponics

You can grow a variety of plants with the Dutch bucket system. It also allows growers to grow large, vining, fruiting crops or any plant that needs a high amount of nutrients.

Dutch bucket system, you can grow cucumbers, peppers, potatoes, squash, and pole beans. And, tomatoes are the most commonly grown in this kind of system. As tomatoes are vining plants that take up large spaces and need support, the Dutch Bucket is very suited.

In commercial hydroponics the most commonly grown plant in Dutch buckets is tomatoes, but you can produce virtually any vining plant. Plants such as Tomatoes, cucumbers, beans, peppers, and eggplants all grow well in Dutch bucket hydroponics. The seedlings are normally started in rock wool 1.5-inch cubes and when the plants are 8 -12 inches tall and ready to be clipped up to the plant support systems they are ready to transplant in a Dutch bucket system.

Advantages of Dutch bucket hydroponics

• The Dutch bucket system is great for fruiting plants, bushy, and vining plants like peppers, tomatoes, cucumbers. This system is space-saving, especially for high vining and large crops.
• Flexible in size and setup – Can scale to any size growers want convenient for pest management in case it occurs in one bucket as each bucket can be replaced easily without affecting the whole system.
• Recirculation system – All the drained water and nutrients are not lost but return to the reservoir if you set up the Dutch bucket system with the return line.
• This is a great hydroponic technique for beginners. It is easy to set up. Dutch Bucket allows starters to grow harder plants such as tomatoes, peppers and enjoy great results.
• It is well-managed systems that can conserve water and large amounts of nutrients, even in a flow-to-waste setup system.
• This system works efficiently in controlled environments for year-round growing. They help save space compared to conventional methods, mainly for vining and large crops. The majority of set-ups reduce labor for a lot of plants.

Common mistakes to avoid for growing plants in a Dutch bucket hydroponics

Irrigation and fertilizer problems – Not understanding the relationship between the strength of the fertilizer and the irrigation timing can lead to quick problems in any Dutch bucket hydroponic system. The Bato bucket reservoir, medium chosen, as well as plant size and age, all play the main role in maintaining the proper fertilizer and irrigation programs.

Not cleaning or sanitizing buckets in between plants. Some mediums can be used for multiple growing seasons but with additional care and caution to not cultivate bacterial or fungal problems. Lack of IPM and preventative care for hydroponic plants accompanied by slow reactions to pathological problems. The high density of Dutch buckets can allow for bacterial, fungal, and insect problems to spread rapidly.
