Growing your own fruits and vegetables can be a great way to save money while allowing you to develop a deeper appreciation of your foods. If you’re going to grow foods properly, you’ll need to make sure that you have established the right environment. Because of this, many people use a grow tent, to control temperature and humidity. Thankfully, you’ll be able to build one yourself. Let’s look at how to do this while sticking to a budget.

Supplies

Before you start building your grow tent, you should check that you have all the required supplies. You will need to make sure that you have supports and plastic sheeting, to create the outside of the tent. You’ll also need to get some fans, lights, and a dehumidifier. Finally, you’ll want to make sure that you have the pots and nutrients ready.

Step 1: Set Up the Tent

The first thing that you’ll need to do is build the tent. When doing this, the first thing that you’ll need to do is measure the area. This will give you a good idea of how big your grow tent should be.

When building a grow tent yourself, you’ll need to get some plastic sheeting and supports. This will allow you to enclose the area and create a temperature-controlled environment. You might need to wrap the plastic sheeting around the supports a few times, to make sure that you will be able to control the conditions inside the tent. It’s also important to remember to cut a seal-able slit in the tent, so you’ll have an entry point to tend your plants.

Step 2: Control the Climate

The next thing that you’ll need to do is make sure that you’re controlling the climate inside the tent. This will ensure that you’ll be creating the optimal conditions for your plants to grow. There are a few things that you’ll need to do this. First, you want to make sure that your plants will be well ventilated. One of the best ways to do this is by using a fan.

Next, you’ll need to make sure that you have a lighting source. Plants need sunlight to survive. However, in a grow tent, this might be possible. As a result, you’ll need to include an artificial source of light. This will often come in the form of a lamp (here's a guide on how to choose one I used for my own projects). If you have the budget, you might want to choose something that offers a higher wattage, as these tend to deliver the best results.
However, remember that the more heat you generate, the more ventilation you’ll require.

Finally, you’ll need to include a dehumidifier. This will allow you to control the amount of humidity that your plants are exposed to. To decide the type of dehumidifier you need, consider the size of the tent and the amount of humidity you’ll be putting in. It will dry the air by collecting the water. Some of them have a hose rather than a reservoir (and these are much more efficient from my experience) you can put outside the tent.

Step 3: Put in the Plants

Finally, you’ll be able to put in the plants. For smaller tents, you might want to use pots. However, for a larger tent, you might want to get a bigger hydroponic rig.
When putting in the plants, make sure that they’re getting plenty of water and nutrients.

Step 4: Conclusion

Building an at-home grow tent can be a great way to grow your fruits and vegetables. As we’ve seen, this doesn’t have to be complex or expensive to set-up. So, use these tips to build your own grow tent today.
Actually you can grow almost anything in the tent, and here's a nice list of ideas I found while we were self-isolating. I have grown tomatoes, parsley, kale and lettuce without any problem, so don't be afraid if you're an inexperienced gardener.
