How To Grow Hydroponic Tomatoes 2020

Hydroponic tomatoes are grown in a nutrient solution rather than soil, although they are typically placed in a non-soil material that can support their roots and hold the nutrients. Growing tomatoes hydroponically allows the grower to raise them in a controlled environment with less chance of disease, faster growth, and greater fruit yield. However, hydroponic gardening is much more labor intensive, and sometimes more expensive, than ordinary tomato planting, especially if you have not set up or run a hydroponics system before.
Best Hydroponic Systems for Tomatoes
Tomatoes are hardy enough to work with a wide range of hydroponic techniques. But as they are heavy feeders, the level of maintenance required can be a problem for some techniques.
For example, in the fruiting stage, these plants can take massive amounts of potassium and micronutrients. If you are using a recirculating system, the pH level can get altered pretty quickly.
Even in passive systems, the pH level of the water needs to be monitored closely. But in recirculation, constant vigilance is needed to ensure that no deficiencies occur.
That being said, tomatoes can be grown using any of the following methods:
  • Nutrient Film Technique
  • Deep Flow Technique
  • Drip System

Step By Step Guide To Growing Tomatoes Using Ebb & Flow
Components required:
  • A large reservoir tray/tote bin, preferably with Lid
  • A smaller tray to hold the plants above the reservoir
  • Container pots or net pots for individual plants
  • A simple plugin timer
  • PVC tubing, two different sizes, one ½ inch, and a larger tube
  • Growing medium - rockwool, clay pellets, or mix of coco coir+perlite
  • Hydroponic nutrient mix
Steps Involved:
  1. Fill the reservoir with water. Each tomato plant needs minimum 2.5 gallons. So plan according to the number of plants you want to grow. Use double the minimum quantity.
  2. Make holes in the lid to allow for the tubes. Always use a lid on the reservoir to discourage algae growth.
  3. Fix the smaller tray above the reservoir. For ebb and flow, you need a tray with tall sides.
  4. Install the water pump or fountain pump inside the reservoir. It should be powerful enough to pump water up to the grow tray and flood it. Get an adjustable pump for best results.
  5. Connect the tray, pump, and reservoir using the two tubes. You will need to drill two holes at the bottom of the tray.
  6. Use the thinner tube for the water inlet, and connect it to the pump. In the grow tray, the larger tube should protrude to the flooding limit.
  7. To avoid any loose gunk or growing media clogging your system, install filters on both inflow and outflow tubes.
  8. Run the flooding system once over to ensure that everything works. The outflow tube should prevent the system from flooding your room.
  9. And once the pump is stopped, the inflow tube placed close to the bottom of the tray should drain the water completely.
  10. Place the saplings/plants in the growing medium inside individual pots. Place these pots evenly spaced in the grow tray.
  11. Add the recommended concentration of nutrients to the water. Always use hydroponic nutrients for your system.
  12. Connect the pump to the timer. In the beginning, try running the motor for 30 minutes, every two hours. Do not leave the plants high and dry for more than 2.5 hours.
  13. If growing indoors, install adequately powerful grow lights at proper distances. Make sure that the plants get a good 14-18 hours of light, especially when fruits appear.
  14. As your tomatoes grow bigger and start to ripen, their water and nutrient requirements will increase.
  15. Don't forget to check the water for pH and EC levels, on a daily basis if possible. Always replace the water+nutrients mix at least once a week.
  16. If growing indeterminate tomato plants, prune them regularly, using your bare hands to break unnecessary stems. Consider using a stake to keep the plants upright and above the water/growing medium.
  17. Once flowers appear, you will need to pollinate them using your fingers or q-tips manually. Do this once the pollen-covered sticks or stamens at the center of the flowers get fully exposed.
  18. The time to harvest varies depending on the cultivar used. Some tomatoes bear fruit within 50 days, while some may take as long as 100 days after planting for the first harvest. 
Choosing grow lights for your hydroponic tomatoes
Since you’ll be growing indoors, you’ll need grow lighting. Your tomatoes should get at least 12-18 hours of light daily.
Unlike certain plants, you don’t need to change the lighting photoperiod as the plants grow. The perfect grow light for you will depend on the size of your hydroponic system, your budget, etc.
In general, LED grow lights are the most efficient and powerful lights there are. But, they do carry the largest investment.
If you want something with lower power but even more efficiency, stick with fluorescents. If you want a cheap, powerful solution, MH/HPS lights will work great.
Grow Tent
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.
Temperature
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.
Hydroponics Nutrients
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 Growing Medium
When using the hydroponic system, the growing medium can easily be changed to suit the desired needs.
So far Rockwool is great as it has the ability to hold water well.
This enables the plant to take in sufficient water as well as air.
This material is available in a variety of sizes and you can pick the best pack to suit your system.
