Lettuce and other greens such as spinach and kale may be the most commonly grown vegetables in hydroponics. Many varieties of tomatoes were grown on a large scale by hydroponic hobbyists and commercial growers.. I’ve put together 25 plants that are easy to grow in water or hydroponically. Although many plants root and grow well in just a glass jar and a little water, with proper plant nutrition and sufficient lighting, you can accelerate their growth and harvest faster than in an outdoor vegetable garden..
Below is a list of some edible, easy to grow plants (infographic included) that work very well with hydroponic cultivation. Salads, the perfect ingredient for the salad sandwich in your kitchen, are probably the most common vegetable grown in hydroponics. They grow super fast in a hydroponic system and are relatively easy to maintain.. Lettuces can be grown in any hydroponic system, including NFT, aeroponics, ebb %26 flow, etc..
This vegetable is undoubtedly a great plant if you just start with hydroponics.. Radishes are another vegetable that blends well with other vegetables.. Radishes are one of the easiest vegetables to grow — either in soil or hydroponics. It’s better to start with seeds, and you can see seedlings in 3 – 7 days.
Radishes thrive in cool temperatures and don’t need light. The favorite vegetables, which can be eaten either raw or cooked in your meal, grow well in the water-based environment.. Spinach is a cool plant, so it doesn’t need too much light. You can harvest it all at once or tear off some leaves.
In good climate and growing conditions, you can harvest continuously for up to 12 weeks. If you want to summarize the main hydroponic plants you can start, I’ve created a detailed infographic on plants (vegetables, fruits, herbs) that are best in hydroponics. Basil is one of the best herbs for hydroponic growing and can be obtained from either seeds or cuttings. Basil is a fast-growing plant that often reaches a harvestable size within 28 days in a hydroponic system.
Some varieties thrive better in water than others, and because of the higher yields, it is often preferred to choose a faster growing basil variety. Some of the best fast growing basil varieties to grow include Newton and Prospera. Newton is a uniform variety that has the traditional Italian flavor you try in many pasta sauces, as well as Fusarium resistance, while Prospera is similar in even growth but also resistant to downy mildew. If you’re patient and want to try a slow growing strain for classic flavors, Everleaf and Elidia are some good options.
Like basil, lettuce can be grown hydroponically from seeds or cuttings. In most cases, you can try converting plants planted in soil to a hydroponic setup, but the transition can be a bit tricky and you need to make sure you rinse all the soil off the plant and roots before putting it in the system.. Lettuce is easy to care for and is great to grow along with other leafy vegetables and herbs as long as they have similar nutritional needs such as basil, spinach, arugula and mint. If you’re harvesting from a hydroponic system, it’s often best to follow the same method as if the lettuce were planted in your garden.
Harvest the outer leaves first as needed once they are mature enough to allow the inner leaves to continue growing and extend your harvest.. Peppers are particularly good for growing in hydroponic setups as they prefer warmer conditions.. Why is this important? For people who love fresh peppers, you can harvest and eat them in the fall and winter months when they can’t be grown outdoors. Best of all, they tend to have fewer problems with pests and diseases than those that grow in the soil..
Different types of peppers require different amounts of space between them to grow appropriately.. For example, peppers themselves need to be 18 to 24 inches apart in a hydroponic system, while chili peppers only need half of. To grow big and strong, hydroponic peppers need around 14 to 18 hours of sunlight per day, leaving the remaining amount for a night cycle. Hydroponically grown peppers are usually ripe and can be harvested between 50 and 80 days..
If you want to place your crop, you can plant different sets a few weeks apart so that they mature at different times.. Oregano can be grown hydroponically from seeds or cuttings. However, seeds are often preferred by gardeners, as growing plants remain more loyal to the variety.. The seeds usually germinate in one to two weeks, and you can start harvesting as soon as the plants are around six inches tall.. Rosemary is a herb with a very low germination rate. Although you can grow it from seed in hydroponic systems, you’d better use cuttings if you want a higher chance of the plants survival.
Rosemary grows very slowly and it often takes fifteen months to start harvesting and years to reach full size. This timeline makes it even more preferable to start with cuttings as they are already slightly larger than the plants if you were to start sowing. Spider plants are just as hardy in water as they are in soil and only need a decent amount of light and some water with occasional nutrients.. They’re not picky about the temperature as long as it’s not incredibly humid or cold until they freeze.
Remember that some tap water has a high chlorine content, which is not beneficial for plants. If you don’t have a water filter, you can leave the water outside for over a night or two before putting the plant in. Pothos strains are another great houseplant for growing in water and also thrive best when taken from cuttings.. They can live in water for years as long as they are properly cared for.
As they are hardy as spider plants and enjoy a decent amount of moisture, growing in water may even be preferable. Lettuce is perfect for your salads and sandwiches and is probably one of the most common vegetables grown in the hydroponic system. They have grown incredibly fast and caring for them is just as easy.. You can grow this vegetable in almost any type of hydroponic system, including (but not limited to) NFT, ebb and flow, and more.
Because lettuce is so easy to care for, it could also be one of your first choices if you want to try hydroponic farming for the first time. If you love strawberries, you’ve probably whined about their seasonal nature. You can’t find them locally most of the time and the fruit is generally pretty expensive depending on your location. Hydroponic systems solve this problem by allowing you to source strawberries at any time.
Cucumbers grow quickly and also yield excellent yields in the end.. When it comes to choosing a type, you’re spoilt for choice. Ideally, you can choose between the thick American slicers, the elongated and seedless variants of European cucumbers, or the perfectly smooth Lebanese cucumbers. Spinach is another fast growing plant that may be suitable for your hydroponic system.
While they thrive well in almost all types of hydroponic systems, the nutrient film technique works best.. If you are not satisfied with this option, choose another technique that provides the soil with a nutrient and sufficient amount of oxygen.. As with any other form of hydroponic agriculture, spinach requires significantly less water compared to your home garden. In addition, you can grow them from scratch if they are seeds..
In most cases, spinach is known to grow within a month or 40 days. Make sure the pH is between 6.0 and 7.5 and the temperature is properly regulated. If you’re planning to grow sweet spinach, make sure the temperature is between 65 degrees and 72 degrees Fahrenheit. The plant may take longer to grow if the temperature is slightly lower than the options mentioned..
Ideally, they need around 18 hours of full light at a time.. You can also lift the light rack when your peppers start to grow. When regulating the light, also make sure it’s within six inches of the light.. Among the types, you can try growing the Ace, Vidi or Yolo variants.
Chives don’t need a lot of water, but they do need a lot of light.. Their ideal temperature is warm and they grow best when they receive full light over a period of 12 to 14 hours.. For pH, a value between 6.0 and 6.1 is sufficient. Blueberries are rich in vitamins and another top choice for your hydroponic garden.
Unlike strawberries, blueberries take quite a long time to grow. In some cases it may take months for them to begin to bear fruit. Susan is inspired by gardening, gardens, plants and flowers. She began her journey into the world of plants when she was 12 years old.
She holds a Bachelor of Science in Environmental Sciences from the University of North Carolina.. She is a fanatical gardener and has a passion for growing and enjoying organic food. Hydroponic garden is a method to grow plants without soil. Indoor or outdoor plants get their nutrients directly from the water instead. Some hydroponic orchid growers switch plants with two days of soaking and five days of drying in and out of the water to mimic the plant’s wild experience.
If you are growing hydroponically, you need to use nutrients, as the water alone is not enough to sustain the growth of the plants. Since you don’t normally grow houseplants in a hydroponic system, you’ll need to change the water once in a while to replenish oxygen so the roots still get all the essentials they need.. A hydroponic gardener must consider space consumption, environmental requirements, and growing habits when choosing which plants to grow in a hydroponic system. Tomatoes are known to grow much faster in hydroponic systems than in a traditional garden, making them one of the most popular hydroponic plants..
Again, this does not mean that you cannot grow these types of plants, they are only more difficult to grow in hydroponics.. Less space consumption, reproducibility of environmental requirements, and growing habits of plants are the three main factors to consider before growing hydroponically. To grow hydroponic strawberries, you need strong light, good airflow, and a freezer to cool the plants manually. According to these three criteria, lettuce, kale, spinach, watercress, basil, chives, strawberry, tomato, pepper and cucumber are the best plants to grow in hydroponic systems.
As someone new to hydroponics, it would be wise to choose easy-to-grow plants that enjoy rapid growth. The biggest challenge with hydroponic growing is ensuring that your system can support the weight of your plant’s huge fruits.. Nutrient Film Technique (NFT) is an active hydroponic system in which water containing dissolved nutrients is pumped into a breeding dish so that plants can absorb these nutrients as the water flows through their roots. However, some plants are better suited to hydroponics than others, and there are even some varieties within different plant species that grow better than others..
It is one of the most popular and versatile systems for hydroponics and can be particularly useful for fast-growing, light crops such as lettuce, although it’s not as effective for growing heavier plants like tomatoes.
