Can You Grow Tomatoes In A Grow Tent – A Quick Guide 

  • Step 1: Decide on the type of tomatoes you want to grow
  • Step 2: Plant the tomatoes
  • Step 3: Pay attention to the germination process
  • Step 4: Water and fertilize your tomatoes
  • Step 5: Harvest the tomatoes

Step 1: Decide On The Type Of Tomatoes You Want To Grow

Before you can use a grow tent for tomatoes, you will need to decide on the type of tomato you would like to plant. Yes, there is more than one. 

Now, tomatoes can be categorized into two types:

  • Determinate tomato plants
  • Indeterminate plants

Determinate Tomato Plants

The growth of determinate tomato plants will only reach a certain size before halting. 

They are therefore a fantastic choice for a large number of plants or locations with little available space, like your living room.

You have a smaller plant with determinate types, therefore tomato cages or stakes may not be necessary.

Despite the fact that its fruits ripen early, they frequently produce all at once, giving you a brief season.

The following are several determinate indoor tomato types:

Indeterminate Tomato Plants

Indeterminate types keep growing and producing fruit all season long. They often grow large and begin to resemble shrubs rather than tomato plants.

You can enjoy the fruit of indeterminate kinds for a longer period of time than you would with determinate varieties, which is an advantage.

Nevertheless, choosing a determinate variety may be the best option if you’re growing inside because it might help you conserve space.

The following are several indeterminate indoor tomato types:

When it comes to growing tomatoes in a grow tent, choosing a determinate variant is more suitable given the limited space. 

Step 2: Plant The Tomatoes

When planting the tomatoes, be aware of the kind of potting mix you chose. 

For the growth of your tomatoes, you can choose from a common starting mix, potting mix, or soil mix.

Check the contents before purchasing a potting mix. It should include ingredients like sand, vermiculite, peat moss, and compost. 

The key to any potting mix is good drainage and here are some suggestions:

Step 3: Pay Attention To The Germination Process

The process of a seed becoming a seedling is called germination. Put your trays inside the grow tent to accomplish this.

Adjust the indoor humidity, and make sure to keep the soil’s daily temperature between 70 and 80 degrees Fahrenheit. 

A hygrometer makes it easier for growers to monitor the moisture level in the growing area. It is incredibly affordable and dependable.

Step 4: Water And Fertilize Your Tomatoes

Providing your tomato plant with enough water and the right fertilizer is a no-brainer. 

Remember how the first step in this process is to choose your tomato variety? 

The choice of your tomato will affect how much fertilizer you need to use.

 Tomato types that are indeterminate will carry on growing and they produce fruits at any time of year. You must give your tomatoes enough nutrients to keep this process going.

Within two weeks of transplanting, apply your first fertilizer treatment. 

Until they are fully grown, keep fertilizing your plants every few weeks. Also, make use of phosphorous-rich fertilizer.

Step 5: Harvest The Tomatoes

Your tomatoes will mature in about 50 to 60 days when you grow in a cell tent.

The fruit will first start to mature from the bottom up and the tomato’s color and firmness should then be monitored.

As a tip, purchase some tomatoes from the grocery store if this is your first time harvesting. You may gauge how firm they are and then contrast them with the plants growing in your house.


What Is A Grow Tent And Why Do You Need It? 

can you grow tomatoes in a grow tent

A grow tent is a portable tent that allows you to grow plants indoors. Grow tents are occasionally referred to as grow rooms. The lightweight, sturdy metal poles fit together easily making up the structure, which is then covered with a thick canvas outer coat.

This robust, long-lasting material, which is frequently composed of nylon, polyester, or Mylar, is attached to a reflective inner lining that lines the interior of the tent.

Grow tents allow you to alter and control a plant’s environment, encouraging it to yield the precise results you need.

They are meant to collect and keep in heat, light, and humidity at a customized level which could result in plants developing more quickly, taller, or with larger fruits.

You are doing something that a typical outside environment does not naturally permit and that is establishing and sustaining a controlled artificial mini-climate.

But why would you need a grow tent?? 

Grow tents regulate 3 essential elements that contribute to healthy plant growth – light, temperature, and humidity.

Growing vegetables in a grow tent becomes easy as it helps to provide the ideal miniature habitat for your plants.

The light produced in a grow tent setting is by potent grow lamps that mimic natural sunlight. No light, or very little light, can escape from this sealed, light proof setting.

The tent’s reflective silver or white lining maximizes exposure and minimizes photon losses by reflecting any light inside the tent back onto the plant.

Additionally, it aids in bringing light to the lower portions of the plant, which is a natural setting that may be in the shade or out of the direct sunshine.


A grow tent’s semi-closed environment is perfect for this since it provides insulation, which, together with the reflective lining, aids in retaining the heat generated by the grow lamps.

You have entire control over the tent’s temperature, which you may adjust to your plants’ best demands over the course of their lives.

Despite the weather outside, tents offer a secure, stable environment for your tomatoes to flourish.


You can adjust your humidity in an isolated, self-sufficient environment using a grow tent. 

Naturally, your humidity will be perfect if you manage the light and temperature effectively and monitor them with a hygrometer and thermometer. 

In a semi-sealed environment, nothing is subject to erratic weather, so your humidity will remain steady, and won’t be exposed to any hazards from the outside world.

Another benefit of being able to regulate what enters and leaves your grow tent is that it will lessen the possibility of insect pests infesting your plants, as well as the possibility of mold spores or plant diseases from outside sources infecting your crop and killing it.

Can You Grow Tomatoes Indoors?

The quick answer is yes, you can grow tomatoes indoors.

Tomatoes must grow in a way that almost exactly mimics outside circumstances since, unlike other house plants or vegetation, they never really adjust to indoor life.

A stable, somewhat warm climate is desirable, as are at least 8 hours in direct sunlight or a grow light.

The advantage of cultivating this fruit inside is that the plant is protected from inclement weather and ravenous pests, so you might be trading one obstacle for another.

Since a tomato plant lacks sentience, it is unable to distinguish whether it is growing outside, indoors, or in a glasshouse.

A tomato plant can tell when its needs are being supplied and will react accordingly.

So what is required of a tomato plant?

  • Circulating fresh air
  • A good range of temperature
  • Water
  • Abundant light
  • An appropriate vessel for growing
  • Healthy growth environment 
  • Branch support in the physical world

Can Store-Bought Tomatoes Be Used To Grow Tomatoes?

Unfortunately, no. Many people wish they could just grab a fruit or vegetable from the shop, bury it in the ground, and have a gorgeous, vibrant tree full of their favorite foods.

Most fruits and vegetables are normally cultivated in a way that prevents self-reproduction, including tomatoes. Most often, they no longer even sprout from seeds.

Nevertheless, you might be able to use the seeds from locally farmed or heirloom tomatoes. Cherry tomatoes can also be sliced in half and seeded to produce a budding plant, similar to potatoes.

How Much Time Does It Take A Tomato To Grow?

It takes about 50 – 60 days for tomato plants to be optimal for harvest. 

There are a number of variables that can affect how long it takes to grow a tomato plant indoors. 

The season you plant a crop will affect how long it takes it to grow when planted outdoors. For example, the early season requires roughly 70 days, the midpoint requires roughly 50–60 days, and those grown in the late season can require up to 80 days.

However, keep in mind that this estimate does not take into consideration the type of gardener you are when it comes to growing vegetables in a grow tent. The growth might be slowed down by unfavorable growing conditions.

Can A Tomato Plant Survive The Year?

Yes and no. The ideal situation would be for the plant to remain active all year and continue to produce fruit without the need for a transplant, sadly, it is not quite that easy.

The bush-like plants usually produce enough fruit for one harvest before dying, however, they could sprout the following season.

Although they produce substantially less fruit in the winter, tomato plants that resemble vines are more likely to survive the entire year.

The average indoor plant won’t grow as much as an equivalent outside plant, but just because the output has decreased doesn’t indicate the plant is dead or won’t produce again in the future.
