Once you are truly ready to dedicate yourself to gardening, this magical hobby will lure you into itself, and you will become an addict. Of course, without the slightest negative implications! What I am trying to say is that when you actually succeed in growing any plant, the ideas will consequently grow larger and larger. Starting from a single and simple container, you will eventually start a cheap indoor greenhouse and end up with an exotic Eden of yours. Or a vegetable paradise, for that matter.

So, if you are in the mood for something quite challenging why don’t you find out how to start it. I have collected plenty of useful information on the topic so stay with me if you are willing to get down to this complex yet not so complicated project.

Conditions Needed to Start a Cheap Indoor Greenhouse


Conditions Needed to Start a Cheap Indoor Greenhouse

This is the part which definitely requires the most of your attention, as you cannot just simply let things go like that. You have to set up control over the conditions.

1. Heating

Those who live in a cold climate will have to find a good way to insulate the glasshouse. Despite the fact that it will receive plenty of sunlight during the day, the situation drastically changes when the night comes. It cools off quickly, which is why a heating system can come in handy. You can choose between gas, oil or solar heaters.

You can also use some products. If you want my recommendation, I would go with this Sudden Shade Cooling Kit. It is extremely easy to use, it doesn’t unravel, and you can cut it to the size you need with no struggles.

Here’s an extra cool tip for you:

Place rocks or barrels of water inside the glasshouse to capture the heat coming from the sun. It will maintain the optimal warmth plants need during cooler evenings.

2. Ventilation

The same way we do, plants need fresh and ventilated air. Since this one is also related to heating, make sure the system you have inside the glasshouse has an automatic shut-off.

Monitor the temperature closely. You can opt for some hydraulic vents which are sensitive to temperature. They open and close automatically.

Truth be told, these might be a little expensive (especially if you are spending all your money on new plants, like I am). I used to spend fortunes, but I found out that a simple fan, like this one, work rather an amazing job!

3. Shading

Shading is particularly crucial detail to pay attention to, as the direct sunlight can burn the plants. There are, indeed, numerous options which are a good thing considering the budget as well.

Some of them are vinyl plastic shading, wooden or aluminum roll-up screens, shade clothes made from polypropylene or some pain-on materials as well.

4. Pests

The logic is more than simply- let the good bugs in and move the bad ones out.

Cleanliness in the first place will help in reducing problems with pests. This goes both for greenhouse itself and the tools. In addition to this, pay attention to the plant itself when you buy it, make sure it is disease and bug-free.

If the problem still exists, simply remove such plants.If you remember, I already mentioned Espoma Organic Earth-Tone insecticidal soap when we talked about aphids and how to deal with them. This insecticidal soap has shown very well in my hands. It can easily deter or kill the bad bugs.

Speaking of, they can be eaten by the good ones as well.

Bugs which may be your allies are green lacewings, ladybugs, whitefly parasites or spider mite predators. You can check my list of beneficial insects for your indoor garden to learn more.

Of course, bugs cannot solve all of your problems, so some sprays will surely come in handy. Here are 5 fantastic recipes for homemade bug sprays.

As I said, this project is multilayered, yet it’s not overly twisted. Even the beginners in the field can easily understand what to do.

You will need certain tools, a good and detailed plan and above all, patience and will. If you don’t have these key ingredients, then better don’t get involved in something like this.

But, I can assume that you have them. I mean, why else would you be here with me reading this?

General Tips on Greenhouses

So, the first thing to have in mind is that this is a long-term investment, despite the size and quantity of species you are planning to grow. Plants grow, so make sure you provide ample room to support this. Light and headroom are also important aspects.

I will say this again, this doesn’t have to be a costly project if you take some time to find the affordable kit necessary for this establishing a greenhouse inside your home.

1. Types of Indoor Greenhouses

Indoor greenhouses mostly come in two variants- attached and freestanding

Attached

The model that doesn’t require you to build all four walls is attached or a lean-to greenhouse. This is a huge advantage because that fourth „wall“ is already a sturdy one (in your house or garage). These are usually less expensive, and they are good for growing veggies or herbs. However, the sunlight is limited to three sides, which is considered as a disadvantage.

Freestanding

On the other hand, the model that you can place wherever you want is known as freestanding. This is usually a bit more expensive option at the initial phase. But, they allow you to grow more plants in them which is definitely a great advantage. What some people also point out as a good side of this type is that it represents a sanctuary away from home. It’s only flowers, plants and you, no devices to distract you.

2. Glazing

Glazing is the covering around the greenhouse frame. The purpose of this is to keep the sunlight and warmth inside while the other elements are outside. The best, but the costliest material for this is glass.

Instead, you can also use plastic, but it deteriorates more quickly than the glass counterpart.  There’s an alternative in the middle- polycarbonate. You can use it on bent or flat surfaces. Some of the advantages of this material are – it is lightweight, retains heat better, it’s sturdier, transmits light well etc.

3. The Right Spot

Choosing the appropriate site is also of vital importance. Here’s one simple yet extremely logical fact- the closer it is to your house the more often will you use it.

Besides this, water and electricity sources are much closer in that case. It should be a level area with maximum exposure to the sun, or at least 6 hours a day. This particularly goes for winter time, If you think the plants don’t get sufficient light, compensate it with grow lights.

4. Drainage system

And, the last but not the least important basic tip- drainage! Place the greenhouse so that it has proper drainage, but at the same time keep the weeds out.

These are the things to pay attention to when you decide to move the plants outside.

 How to Start Cheap Indoor Greenhouse

1. Which are the cheapest alternatives for containers?

Anything can do, as long as it allows the plants to receive enough sunlight. You can use some tall and translucent plastic bottles, such as those for milk, vinegar, juice etc. Plastic product containers can also work. You can reuse and recycle them; this decreases the costs significantly. Make sure they have a hole in the bottom, to serve as drainage.

2. Is it safe to buy seeds online?

Of course, as long as it’s a reputable source. As a matter of fact, if you are looking for something less popular or simply less known, this is the only way to get it.

3. What to do if there are more seeds than I need?

Here’s where you actually spot the social aspect of growing plants. You can share them with friends and neighbors in this form. The other option is to plant them, and swap seedlings when it’s time to transplant them. If none of these two works (meaning there’s no one interested in growing plants), you can keep them for next year, provided that you store them properly.

4. What can I use as a shelving unit to store plants?

This mostly depends on the number of containers you have. But it would be wise to choose someplace where conditions will be stable so that you don’t have to move the plants every now and then. An old bookshelf can work perfectly. If you are crafty enough, make one yourself. On the other hand, you can buy one.
