Spinach – Grown in Hydroponics

Today we share with our readers the growth of Spinach in a hydroponic setup as done in the CityGreens Research unit in the rooftop space.

We have successfully grown Spinach in 2 types of Hydroponic setups in the CityGreens rooftop.

  1. Using Deep Water Culture (DWC)
  2. With coco-peat in grow beds

With both these methods, we obtained a good yield. I must mention that the taste and quality of the crop were far better than anything I’ve purchased from the local market. Customers, who bought our produce, shared with us their joy and delight at receiving such clean and fresh spinach.


Our happy customers!

Nothing to match this smile!


Let us explore the process of growing Spinach in 2 stages.

Stage 1: Sowing.

We sowed spinach seeds in the pro-trays and kept them covered in a dark place to enable the seeds to germinate. You need to keep the pro-trays sufficiently moist and away in a dark corner.

About the 3rd day, the seeds started to sprout. Now is the time to keep the pro-trays exposed to sunlight – mainly the morning sun – for approximately 3-4 hours. With regular care and watering, these small seeds grew into healthy saplings within 7-8 days. It is now time to transplant them into the different mediums.


Stage 2: Transplanting and caring for the plant

We transplanted these saplings into both grow beds with coco-peat as well as in DWC units set up with nutrient-rich water. In both cases, we used the CityGreens NPK solution to grow the Spinach.

Grow beds :
  1. The saplings were supplied alternately with water and with CityGreens’ nutrient-rich solution.
  2. We ensured sufficient sunlight to enable the plant to grow.
  3. We mixed the coco-peat in the grow beds with a medium to enable the root to be sufficiently aerated.
In Deep Water Culture System:
  1. The saplings from the pro trays were transplanted into the nutrient-rich water. We transplanted them in 3 layers one below the other.
  2. The roots were kept aerated intermittently to ensure that there is sufficient oxygen to the root system to enable them to grow and thus support the plant growth.
  3. Whenever we felt that the sun was too harsh on the plants, we provided them with an additional foliar spray of plain water.

Spinach Growing in DWC

At the end of 4- 5 weeks the spinach was ready for harvesting.

We are happy to share that our customers wait eagerly for the spinach – fresh, tasty, pesticide free and with minimal cleaning.

You too can relish Spinach with all its nutritional properties intact – from farm to fork in no time. This is a must attempt crop at home.

Happy Growing!

Sometimes you choose your profession. Sometimes God chooses your profession for you. For me it was the latter – The quest to find purpose and expression came in the form of my work. A connection with soil, water, growth and life.

As a kid, I would secretly wish that grown-up life was just like my childhood – running around luscious green fields, feeding the farm cows, chasing and being chased by hens, goats, cousins, the wind in my hair, the rain on my face, the smell of the earth after a rain, and the sound of non-stop laughter.

It was a sad day, when I realised that my wish was just that – a wish! Its been a personal mission for me to recreate the magic of my childhood in any way possible and contribute to clean air, smiling faces, nourishing food, happier homes all with a sense of awe and gratitude. Thus I found my way to CityGreens – here I help people sow, plant, nurture, care and harvest plants. Through plants a better home and life.

When I was not running around and playing with my cousins and farm animals I also managed to do my B.Tech and MBA.

    It would help if you can add links to the exact nutrients used from your amazon store. We willhave summer setting soon.Also what are the temperature range we can grow spinach ?

      Hi Amardeep,
      Thanks for writing in.
      We have used City Greens NPK solution for growing the Spinach.
      The details of this have been shared in our previous write-ups/articles.
      Nonetheless, will include the same in this article as well.
      Thank you for your feedback.
      The temperature range for spinach is 21 to 26 degrees Centigrade. it can tolerate more temperatures as well.

      Happy Growing!
      Team City Greens.
