Can You Grow Tomatoes Indoors?

Can You Grow Tomatoes Indoors?

Growing tomatoes indoors is possible and highly rewarding. We all know that tomatoes that we grow ourselves taste better than what we buy in a supermarket. Let us now look at the facts that every person that is considering indoor tomato growing has to know.

Tomato variety needs to be analyzed first. You require a crack resistant one. Not every tomato can deal with indoor environments. Then we have to analyze the soil. A standard potting soil stands made out of equal parts of vermiculite, sphagnum peat and perlite. Correct PH can easily be adjusted if you use one hydrated lime teaspoon for every gallon of soil mix. Tomato seed planting is done after soil is prepared. This is sometimes a little difficult. Starting seeds are equally important to plant growing. When planting tomato seeds there is a need to always plant them properly, at a depth of 1/4 inches and 8 seeds have to be used for every inch. After your planting is over you need to cover the plants for a few days.

Now we are faced with the one part of growing tomatoes indoors that is the easiest: taking care of the plants. They need to stay under two or three good fluorescent lights that need to stay on from 18 to 24 hours daily. A perfect temperature for growing is 70 degrees in daytime and 65 degrees in nighttime. Transplanting the plant is necessary after you see it reach a minimum hight of around 12 inches and you need to use one gallon containers. When 60 days passed the fruits should be perfect for picking.

When you grow tomatoes indoors you will find the most difficult part being flowering. In order to do it properly there is a need to know force flowering. You can see that one tomato will flower in 2 months while the one near it can even stay 80 days till flowering. If you want to begin flowering the plant has to be moved in a container of 3 gallons. What you always have to remember is that if you have problems do not hesitate to ask for help. You can both flower and grow tomatoes indoors but you will find it to be a little more difficult when compared to an outdoors environment.
