Hydroponic growing solution

There are endless possibilities when it comes to Hydroponic growing solution.  Whether you purchase nutrients from a Hydroponic store, use a traditional soil fertilizer or make your own there are some universal things to know


There are two kinds of nutrients that your plants need: macro and micronutrients. Macronutrients are those that plants need in large amounts, including carbon, phosphorous, hydrogen, nitrogen, oxygen, sulfur, potassium, magnesium, and calcium. Micronutrients are needed in tiny amounts but are essential. These include zinc, nickel, boron, copper, iron, manganese, molybdenum, boron, and chlorine.

There are some great hydroponic specific grow solutions on the market.  General Hydroponics has a line of products that are well labeled and easy to use.  The Maxigro is great for general use.  They also have a line of liquid plant specific products.

Non Hydroponic specific fertilizer can also be a great choice.  Many companies of traditional fertilizer are now including hydroponic instructions on their packaging. 

Things to keep in mind when using soil fertilizer are;

you normally need a much smaller amount because it will be in great direct contact with the plant roots

these fertilizers assume that your plants will have access to other nutrients normally found in any soil, so make sure that you add a good full spectrum of nutrients 

make sure the fertilizer is water soluble and will stay suspended.  The suspendtion is of special importance if you use a non circulating hydroponic planter


Homemade growing solution.  This is a great, inexpensive and usually organic way to go if you have the time.   There are literally thousands of homemade fertilizer techniques.   When it comes to use in Hydroponics some kind of compost tea works best.  Compost tea needs to follow the same guidelines as any nutrient solution...full spectrum and suspend in water


A great way to provide a good nutrient base for your plants is to use a fish tank.  Whether a small home aquarium or a commercial fish aquarium, fish “poop” out the nutrients the plants need and the water temp and PH levels for most fish are the same as most plants.  Turning Hydroponics into Aquaponics

The PH of your growing solution is critical.  If the PH is to high or to low, you plants can develop Nutrient Lockout.  Which is when the roots are simple not able to release the nutrients they need from the water.   If your plants look weak or pale, before you add more nutrients, check your PH. Most plants like a PH around 6.5 but check your specific plants preferences. 

It is cheap and easy to check PH levels with fish tank PH strips.  Some garden PH testers will not work to test water so double check your test method 


Water temperature is very important.  Just as traditional plants like to grow it certain temperatures so do hydroponic plants.   Most plants will do well with temps in the mid 70degree range.

if you grow inside the heating the grow solution is important.  Use a submersible water heater like a fish tank heat to keep the temperature in range.

If you grow outside or in warm places you need to cool the water down.  Keep the nutrient solution in a light colored reservoir out of direct sun.  There are lots of ways to keep in cool depending on your setup

These are just the very basics

Like all gardening, start with the basics then play around and experiment to find what you like best!
