Hydroponic systems allow you to grow fresh herbs, vegetables, and fruit at home using no soil and minimal water usage for year-round gardening. Sort out the top hydroponics.
Select your system by taking into consideration available space, your level of gardening skill and aspirations, and desired maintenance duties. Automated systems offer less work, while DIY options provide a more hands-on approach.
1. Deep Water Culture (DWC)
Deep Water Culture (DWC) is an increasingly popular hydroponics method. Plants sit in nutrient-rich water that has been enhanced with oxygen through an air pump, making it easier for their roots to absorb all necessary nutrients for faster growth. There are numerous advantages associated with DWC that make this an attractive option when growing various species of plants.
Traditional DWC setup involves placing plants in net pots containing lightweight growing media. A water pump then connects to the system and dispenses nutrient-rich solution directly onto roots before returning into the reservoir and recirculating again – known as Recirculating Deep Water Culture or RDWC system.
DWC can also be utilized by placing your plants in one single container that serves both as a reservoir and grow site, with their roots hanging into it while being filled up every time the air pump comes on and then circulated through the system for use throughout. This ensures it always has optimal temperatures, EC levels, and pH levels necessary for healthy plant development.
DWC gardening is an ideal choice for beginners, as its setup and upkeep are simple and maintenance requirements low. Furthermore, this form of gardening tends to be less susceptible to pests and diseases than other forms of gardening; nonetheless, it is still vital that plants are monitored frequently in order to promote optimal growth.
If your plant begins producing flowers, for instance, you should adjust its feeding schedule in order to promote healthy blooming. Furthermore, it’s also wise to monitor for any issues with nutrient deficiency or root rot that might arise.
Leafy greens like lettuce and kale flourish well in drip watering systems (DWC), as do herbs, tomatoes, and peppers. But the right strain must be chosen for a DWC setup, as some varieties don’t thrive here. Royal Queen Seeds’ Amnesia Haze strain has proven particularly potency when grown this way, while Seedsman offers Blue Cheese, which boasts powerful highs with its intense cerebral effects.
Aeroponics is one of the more prevalent forms of hydroponics, with growers being able to produce up to three times as much in an identical space using this growing method due to increased oxygen availability for plants that help their development faster while simultaneously growing taller and fuller yielding increased harvest yields in less time.
Aeroponic systems use net pots suspended above a deep reservoir filled with an oxygen-rich nutrient solution to submerge plants’ roots in oxygenated water, helping them thrive and yield an assortment of crops. Unfortunately, operating this type of hydroponic system requires some technical know-how for successful operation – for instance, knowing which nutrients your plants need in order to provide enough of each in the right amounts – as there’s no soil to absorb excess or incorrect quantities if supplied, leading to toxicities or imbalances that could result in plant death toxicity or imbalance. Finally, disinfection should take place regularly – hydrogen peroxide is an ideal disinfection method!
Aeroponic systems come in various varieties, from recirculating to draining to waste. Two that stand out are High Pressure and Ebb and flow systems. Both offer their benefits; choosing one depends on your unique requirements and budget. Recirculating systems may save money by reusing the same nutrient solution for longer before becoming too dilute and needing topping off, making this an economical solution than drain-to-waste systems, which require you to replenish your nutrient solution supply constantly.
An ebb and flow system is ideal for beginners looking to get into aeroponics, as its setup and usage are straightforward. While you could use this setup for growing leafy greens, herbs, or vinegar (e.g., tomatoes, capsicum, or cucumber), an additional bonus is that this system uses 20% less water than DWC systems.
3. Candle Wick
Hydroponics can help any gardener, whether indoor or greenhouse grower. Not only do hydroponic systems save space and use 90% less water than traditional soil growing methods, but they can also deliver high-quality fruits and vegetables in half the time!
All plants require water, oxygen, light, and nutrients in order to thrive; manufacturers now offer hydroponic systems that automate many of these steps to bring these essential elements directly to your plants.
Hydroponic systems are ideal for growing herbs, lettuce, and small tomatoes; additionally, they can produce other fruit and vegetable species using accessories like an automatic watering system or additional lights. Furthermore, this kit requires no electricity, making it an excellent option for DIY home gardening enthusiasts.
Although wick systems can be an excellent system for beginners, they do have some drawbacks. Their main downside is that they remain damp and humid throughout their lifespan, leading to fungal outbreaks or rot in organic growing medium. Furthermore, it may not provide enough hydration and nutrition to root vegetables or leafy greens that require constant attention and food.
Wick systems can quickly overheat, leading to inconsistent burns. To avoid this issue, ensure that the melt pool reaches all four walls of your container without mushrooming or carbon build-up; additionally, the wick length must be adjusted appropriately so as not to become too long.
An alternative to the wick system is an ebb and flow hydroponics system, which is part of NFT (nutrient film technique). It works by flooding a grow bed every few hours with nutrient-rich water that then slowly drains away through gravity into its reservoir below, keeping roots exposed to nutrients at regular intervals while also helping avoid overwatering. Furthermore, its versatile nature means it is suitable for growing large plants since multiple planters of different sizes can fit onto one bed at the same time.
4. String Hydroponics
In the 1970s, aerospace plant physiologists started exploring ways to cultivate plants in one of the harshest environments known to humanity: space. With help from physicists and biologists, they created hydroponic systems that enabled astronauts to enjoy fresh, nutritious green vegetables during space flights. Since then, scientists have worked to bring this technology back down to Earth so it can benefit humanity more broadly.
Hydroponic systems enable crops to be grown in an inert growing medium that replicates soil found in gardens, using either the nutrient film technique that floods roots with nutrients before draining off to reuse the water or drip systems that use Ebb and Flow to feed nutrients to plants passively. Plenty and Bowery Farms in NYC use hydroponic growing systems like these in order to produce lettuce, spinach, and other leafy greens for sale in their stores.
Setup and operation of these systems require only minimal specialized equipment; for instance, wick systems can be assembled using household items like buckets and an absorbent material like string, nylon rope, or strips cut from old clothing – an excellent way to introduce kids or newcomers to hydroponics.
The primary advantage of wick systems is their simplicity and affordability, making maintenance both straightforward and straightforward. Unfortunately, their wicking action can lead to mineral salt build-up that needs to be flushed away regularly, and since nutrients don’t reach all plants evenly, this method works best with smaller species like herbs or salad greens.
Hydroponic systems provide plants with a safe and controlled environment, mitigating many common issues found in traditional outdoor and field gardening. Fungus that destroys crops is prevented, rabbits and locusts don’t devastate harvests, and adverse weather conditions like high temperatures and heavy rain can be avoided with an automated hydroponic system, which is why the Food and Agriculture Organization of the United Nations advocates its use in countries which face hunger issues due to climate change.
