Fastest Growing Hydroponics Plants - Large Harvest Heavy Fruiting Plants
Fast-Growing Hydroponics Plants
If you've ever set up a hydroponics system, or if you're running a system currently, you will know how frustrating it can be waiting for plants to be ready for harvest so you can share them with friends and family. It really helps when you get a fast-growing hydroponics plant to keep you motivated during your hydroponics journey.
I’ve experimented with quite a variety of hydroponics plants and made a short list of fast-growing options. Of course, most of them are vegetables due to the fact that fruit plants usually take a long time from planting until harvest. My Aquaponics setup at home has also shown great growth from plants that rely heavily on nitrates to grow. This means spinach and other dark green vegetables are the fastest growing vegetables and do great.
List of Fastest Growing Hydroponics Plants
Spinach of any variety does great in a hydroponics system. It really loves a nice moist environment and will be ready to harvest from a seedling after around 14–20 days. This may sound like a long time, but if you plant many spinach plants close together, you can get quite a large harvest, and if you harvest the leaves every week, you should be able to maintain a steady supply of spinach to feed your friends and family.
Like all plants, young spinach seeds and seedlings are sensitive to frost and will usually show no growth below 10 degrees Celsius (50 Fahrenheit). For optimum growth, temperatures in your green house (if you have one) should be kept at around 24 to 30 degrees Celsius (75 to 85 Fahrenheit)
The best thing about spinach is that it grows incredibly quickly, and you can begin harvesting once the leaves are an edible size, just like baby spinach. When harvesting, it's best to start from the outside of the plant and leave the inner parts to grow larger. Spinach contains one of the highest levels of zinc from a plant source.
Swiss chard is a very popular hydroponics plant and is one of the fastest hydroponics plants I’ve seen. Swiss chard will survive in soils or nutrients with a pH of around 6.2–7.
You can harvest Swiss chard at around 35 days. Even after harvesting, it will continue to grow and prosper and provide heavy harvest. The plant is very versatile and can tolerate most temperatures but thrives in cooler weather. Soil temperatures of 10–30 degrees Celsius are recommended, and it's best to plant late in summer. It’s very hardy and can handle some light freezes and frost.
Seeds for Swiss chard should ½ to 1 inch deep, and around 3–6 inches apart. Much like beets and other chards, it will produce more than one plant from the seeds, so it will require a little maintenance to ensure the plant can grow freely.
Swiss chard loves full sun, and seeds can be saved for up to 5 years, so it's easy to collect the seeds and save them for future planting. Swiss chard also has high levels of vitamin K not seen in any other plants.
Mint and Spearmint
Mint is probably my favourite as I love to chew on a mint leaf or make my own minty tea, and it's definitely the fastest growing hydroponics plant I’ve come across so far. It can take a long time to grow from a seed because germination can be tough and requires quite a lot of patience, but once it has reached the young plant stage, it will go crazy and really take over your Aquaponics system.
The best thing is to buy a mature mint plant from your local nursery and transplant it into your hydroponics system. Mint takes very little care and only requires a good water supply for optimal growth. It's great for Vietnamese cooking and in fresh salads.
That’s it for now, but I may add some more in the future as I am having great harvests from my radish and turnip plants.
