A look at growing tomatoes in hydroponic gardening
Ideally, the yield from growing tomatoes using hydroponics is around 40 pounds per square foot yearly. But you must use the correct nutrients and take really good care of your tomato plant.
With all conditions meet, a hydroponic farmer will harvest about 45 to 50 pounds for every square feet, this is according to A & G Agrilife based in Texas.
While practicing hydroponic gardening of tomatoes, there are three systems that can be used to sustain the tomato plants.
The original method that was in use at the beginning was the ebb-and-flow method from the 1930s to the 1970s.
After then, a new system was introduced known as the Nutrient Film Technique (NFT).
Later on, the drip irrigation system was invented and offered to the farmers.
Ebb and Flow System
The ebb and flow system are often used at home for domestic use.
It also the most preferred for amateurs who are just getting into the business.
This is because they are simple and also cheap.
Important to know is that this system can also be used to grow hydroponic lettuce.
In this system, the solution is usually pumped from the reservoir to the grow tray until it is flooded.
The pump is then turned off and the grow tray is drained completely.
The only problem with this is that the nutrient that each of the plants takes in is not in the control of the farmer.
Nutrient Film Technique
The Nutrient Film Technique changed the original concept in that the rooting medium was no longer essential and instead the roots of the tomato plants were bathed in a flow of nutrient solution.
This was made possible because the tomatoes were suspended on a slightly slanted surface.
The nutrient solution was then slowly pumped gently or let to trickle down the slope from the reservoir.
Since the roots of the tomatoes would be hanging down, the nutrients could easily be absorbed by the plant.
This system was often used commercially.
On the other hand, there could be an issue as the plants higher up could receive more nutrient as compared to the plants at the bottom of the slope.
When drip irrigation was introduced, water, as well as a nutrient solution, are placed at the roots of the tomato plants in bags or even buckets, learn more.
Although this system works similar to the ebb and flow system, it is more convenient.
This is because the solution is pumped from the reservoir through a network of tubes and eventually drip-fed to the plants.
Here, you can easily regulate how much each plant absorbs.
This system has turned out to be quite convenient and well-designed to the farmer.
However, in the recent time, there are numerous selections that farmers can use.

The best way to grow hydroponic tomatoes is by taking into consideration the following areas:
Soil Mixture starting seeds
Step one of learning how to grow tomatoes is creating the right environment for your seeds by ensuring the right soil mix.
The soil mix you should be a standard soil-less potting mix, add to it a worm casting of around about 10%.
Standard potting mix is usually done with equal parts of:
Then one teaspoon of hydrated lime for every gallon of soil mix is added to help adjusted to the right pH.
When it comes to tomatoes, adjust the pH the soil-mix this way because the lime is a good source of Calcium (which prevents blossom end rot in the tomatoes later on).
Using plain water and thrive alive B1, moisten the initial potting mix little by little.
To get the right mix a handful of potting mix is enough then make just a few drops.
In case the mix get too wet, add dry vermiculite or you can try perlite (just a handful) then remix.

In growing tomatoes hydroponically, tomatoes starting seeds are crucial in the success of your crop yield. And when it comes to how to grow tomatoes the same applies.
Best way forward is to begin with a good nursery tray and fill it with the soil mix you have prepared above.
Plant your tomato seeds 1/4 inch deep and about 8 seeds/inch.
So as to ensure your seeds don’t dry out, it is advisable to cover them for a few days.
Use a seed starting tray that has a lid and in case you don’t have that get a plastic wrapper.
The right atmosphere for tomato seeds germination is 80 degrees for 5 to 12 days.
Once the seeds begin to sprout remove any cover you may have on them.
The sprouting seeds need good lighting but make sure a distance of 4 to 6 inches kept from the fluorescent growing LED lights.
In order to maintain the right vegetative growth of your tomatoes seeds, your lighting should be kept on for 18 to 24 hours a day.
Once the sprout gets to 1 1/2 inches tall, transplant them carefully into a 6 inch container.

No products found.
These grow tent enables you to close off the environment for the tomatoes to give you the ideal grow room.
These tents are made of fabric and allow the conditions within it to be refined for the best conditions for the hydroponic tomatoes.
They are important especially because the tomatoes desire complete darkness for about 8hours.
Usually, it is not very easy to have so much darkness but with the grow tent you can meet the requirements with ease.
The right temperature for tomatoes
Tomatoes desire temperatures of about 18 degrees Celsius to 25 degrees Celsius during the day and 12 degrees Celsius to 18 degrees Celsius at night.
These plants are warm weather plants and can survive high temperatures as compared to the temperatures dropping.
Tomatoes can do better if the temperatures rise for short periods as when they are exposed to frost conditions.
Frost kills the tomatoes faster than you can imagine.
To keep your temperatures moderate, you can invest in a grow tent as it creates an environment that is sealed.
Ideal hydroponics nutrients for tomatoes
Every plant needs certain nutrients that will enable it to grow healthily.
In every hydroponic system, there is a nutrient reservoir that stores water that is fed to the tomatoes.
Soluble nutrients are mixed into the water (for tomatoes Maxsea is the best to buy) that is given to the plants.
You can mix the nutrients in the water to make it desirably rich in the essential nutrients.
Once the nutrients are mixed in the water, it forms the nutrient solution that is fed to the plants.
The pH level as well as the electrical conductivity must be strictly put into consideration when growing tomatoes.
Tomatoes love water that is slightly acidic that has a pH level that is between 5.8 and 6.3.
You can easily and cheaply buy a pH level testing kit to help you to be accurate with the pH level.
The most ideal electrical conductivity needs you to mix the correct nutrients into the water with adjusted pH.
The best electrical conductivity for tomatoes is between 2.0 and 3.5 milliMhos.
Hydroponics tomatoes growing medium

Best Hydroponic tomatoes nutrients
In order to harvest the best tasting and most nutritious tomatoes, you must have given the plant the nutrients that it desires.
There are a number of combined nutrients that are usually dissolved in the water reservoir and will be pumped into the grow bed for the plants to absorb.
In order to come up with the best fertilizer to be used on the hydroponic tomatoes, you must be sure of the nutritional needs of the tomatoes.
These nutrients aid in the growing of flowers as well as fruits.
And in the end, you will have a great quantity of tomatoes that are big and juicy.

For tomatoes, the nutrient solution is prepared in two or three levels that will sustain various stages of their growth.
The macro nutrients are the ones that change and become concentrated as the crop matures.
For the tomatoes, the micronutrients are maintained at a balanced amount. The first stage is for the seedlings.
This is the stage between the first true leaves to 24inches in height and the fruit is 1.5cm in diameter.
During level B, you may need to add the amount of potassium and nitrogen.
The most acceptable pH of the nutrient solution should be maintained at 5.5- 6.0 or can be lowered using phosphoric acid.
