Fast Growing Hydroponics Plants

If you've ever setup a hydroponics system or running a system currently you will now how frustrating it can be waiting for plants to be ready for harvest so you can share it with friends and family. It really helps when you get a fast growing hydroponics plant to keep you motivated in during your hydroponics journey.

I’ve experimented with quite a variety of hydroponics plants and made a short list of fast growing hydroponics plants. 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 and 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.

Climate Needs – 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 it grows incredibly quick and of course you can begin harvesting once the leaves are an edible size, just like baby spinach. When harvesting its best to start harvesting from the outside of the plant and leave the inner parts to grow larger before harvest. Spinach contains one of the highest levels of zinc from a plant source.

Swiss Chard

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, and even after harvesting 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, its 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 , and a lot 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 chards love full sun and seeds can be saved for up to 5 years, so its 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

Probably my favourite as I love to chew on a mint leaf or make my own minty tea and is 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 growths. Great for Vietnamese cooking and in fresh salads.

That’s it for now but I may add some more as I am having great harvests from my radish and turnip plants.

      Hi! Can you post closer pictures of your hyroponic set-up? What's your experience with the water source? Do you find that you have to replace it with clean water every couple of days?

      Swiss Chard is great, one of my favs. Working on putting together a small greenhouse at home this summer and Swiss Chard will be there. Mints are good too, like them in ice tea.

      Ha ha ha! Funny that you mentioned that mint is great in Vietnamese dishes. I just thinking Pho before you said that. Now I'm starved! Great job. It's my dream to build a greenhouse such as the one depicted. I'm tired of getting to the market late and finding that all of the good quality stuff is wiped out! It was fun reading this.
