Growing tomatoes indoors

When I was asked about  growing tomatoes indoors I thought immediately that they were referring to “under glass” greenhouse tomato growing which I thought I could easily write about. Alternatively growing tomatoes indoors could also mean on the windowsill but in fact they were referring to is what I would call the more commercial venture or exceptionally keen tomato growing enthusiasts.

This was something I hadn’t really looked into before now but decided that it would be helpful for people to know exactly what is involved.

  •  The main considerations to take into account are firstly whether the amount of extra work and effort involved in the production of indoor tomatoes is worth your time.
  •  Secondly does the cost of setting up the indoor garden out weigh the savings made from growing your own tomatoes?
  •  The amount of electricity that will be used plus the cost of the extra equipment the space taken up with in the home or garage and the safety aspects of water and electricity in close proximity, or indeed where to put the car!
  • If you choose a bush tomato variety it will need plenty of space in which to grow and will need to be kept under a florescent cool white lighting system for seedlings as well as high pressure sodium light to help force the plant to flower and fruit. These lights remain on for extended periods at a time and need to be positioned at a specific height to maximise the growth potential for the plants.
  • The temperature and humidity for the tomatoes requires regulating as you neither want it too hot or too humid or too cold for the plants.
  • The lighting system can raise the temperature in the room for those plants and therefore you may require a fan to gently move the air around this will also help with the pollination of the tomato plants.

Tomato Hydroponics

Usually people that decide to grow indoor tomatoes will often decide to use a hydroponics system. These systems can also be quite expensive to set up but the growth rate of the plants and the fruit production is the real bonus. The amount of chemistry involved in the maintenance of the nutrient solution for your plants is quite in depth, balancing the Ph of your reservoir has a direct affect on the amount of nutrient added to the water.

My personal conclusion is that you do need to be a very attentive gardener with an interest in the technology of growing indoor tomatoes to embark on this venture.
