How to Make Hydroponic Solution at Home

Growing hydroponically is becoming increasingly popular, and it’s not hard to see why Hydroponic farming is the most effective.

  • It’s cost-effective
  • Sustainable
  • Allows you to grow an impressive range of vegetables and fruits year-round in your own home garden.

The one issue most newcomers run into is the high price of the nutrient solution used to feed the plants, but with this how-to guide on how to make the hydroponic solution at home, you’ll be able to produce your own inexpensively and conveniently!

Hydroponic growing systems are used to grow plants without the use of soil, which allows you to better control how your plants are fed and watered.

While some hydroponic systems require specific commercial solutions, you can make your own homemade hydroponic solution with water, nutrients and additives that will keep your plants healthy and happy.

What is Hydroponic?

Think of hydroponics as an indoor method of growing plants without soil. Plants aren’t grown in regular dirt; instead, they’re grown in containers that hold a nutrient-rich solution.

The plant draws water and nutrients from these solutions through its roots, just like it would from the soil. Some systems use drip irrigation to slowly release nutrient-rich water into planters.

And some commercial growers make their own solutions, but you can also purchase ready-made commercial hydroponic systems or kits online or at your local gardening store.
Aeroponics is similar to aquaponics with respect to growing plants. However, instead of using a separate tank for fish and plants, aeroponics combines them into one closed-loop system in which both types of living organisms mutually benefit from each other’s processes.

The roots of a plant hang over an aerated water supply where they dip in and absorb nutrients from time to time while also being sprayed with a fine mist from time to time in order to keep them hydrated and nourished.

What is the Best Solutions Mix for Hydroponic?

Since there are no set standards on what hydroponic solution you should use, it is important to find out what is in your local water. You want to create a solution that will provide nutrients for your plants while keeping them healthy and safe.

To do so, you have two different ways of adding salt.

  • The first way is by adding about 1 tablespoon per gallon of water. If you live in an area where they add extra chemicals into your tap water or if you notice algae growing on top of it, then add more salt accordingly.
  • If not, then stay with 1 tablespoon of salt per gallon of water. However, if you prefer to use table salt instead of sea salt, then go ahead as long as it is all dissolved before using.
  • It takes around 5 hours for any water conditioner to be completely dissolving into water.
  • And remember that your mix might be perfect now. This changes as time go on depending on how much to add along with any other factors within the environment of where you live.
  • Therefore, regularly testing and adjusting your hydroponic solution is recommended every couple of weeks throughout the entire growth period.
  • For aeroponics systems, you will need to make sure your reservoir stays between 35-45 degrees Fahrenheit.
  • This may require some additional work in order to maintain these temperatures due to cold air in winter months escaping from pipes in colder parts of homes when mixing hot water with the cold air outside when changing reservoir tanks after chilling overnight.
  • The easiest way is by keeping a heat lamp close enough. To keep it warm but not so close that it heats up too much and reduces oxygen circulation inside.
  • If you have a hydroponic indoor garden, then a simple timer is helpful to keep your lights on at certain intervals during day and night. Until buds get fully ripen off.  And mature which takes around 11 weeks grow naturally under an artificial light source.

When to Add Nutrients to your Water?

Unlike soil-based plants, hydroponically grown plants rely on a special nutrient solution. That then absorbs through their roots. You’ll need to regularly add nutrients and supplements (e.g., KNO3, PO4) into your water reservoir.

Aim for mixing these additives into your water every three days or so. While you could buy chemicals from a home supply store. It’s probably cheaper—and safer—to make them yourself with household items.

The general rule of thumb is that your plants need nutrients every time you add fresh water. Since plants use a lot of water, you can also tell. When it’s time to add more nutrients based on how cloudy your solution is.

If you can’t see through your water anymore, it’s probably a good idea to add more. It may sound counterintuitive because you want oxygen in your solution so your roots have access to it.

But if you don’t have enough nutrients in there, they won’t be able to get what they need either. Some people even suggest skipping aeration altogether and just adding nutrients straight into your reservoir. But I think letting some air in help with algae control (and prevents wasting any nutrients).

It’s an open question; do what works best for you and stick with it!

The Rest of the Solution Components for Hydroponic

Once you’ve got your base solution, there are a few other components. You’ll need to get things going: plant food, air pumps and air stones. You can find all of these and more at most gardening stores.

They usually come in powder or liquid form and include micro-nutrients and trace elements. The solution should also contain an air pump and airstone(s) that will move oxygen through your water.

These devices keep your plants alive and healthy by delivering. Just enough oxygen to each root zone without sending too much into it. Which would be wasteful – or not enough. Which would suffocate them.

If your setup doesn’t have any equipment that includes airflow. Then don’t consider it to be hydroponics and falls into another category. This is because hydro needs proper aeration for optimal growth.

Keep in mind that some systems do incorporate lighting into their setups. So if yours does don’t worry about investing in extra lighting until later on down the road. When you start adding vegetables like tomatoes, peppers and cucumbers.
