Greenhouse Planting Guide For Newbies
Doesn’t matter if you have a big or small greenhouse, planting seeds or sprouts in a greenhouse can always be a challenge. To make the process easier for you – here’s a short guide with tips you can follow:
- Pick the right location for the greenhouse. Make sure it is close to your house or cabin so you can go in and out quickly without feeling annoyed.
- It is essential to have excellent sunlight exposure, but it’s also important to have the right shade when needed. We recommend picking a location between a tree or wall and an open space. This way you have both shade & sunlight at the same pace.
- Some bulbs or artificial lights provide a similar effect to sunlight so you can use them along or as an alternative to direct sun exposure for nurturing your plants. But this only works for specific plants, others may not grow without a lot of sun exposure.
- We recommend having great drainage in the place of installation, this way you prevent flooding which can eventually harm the plants or the greenhouse itself.
- Direct access to water is essential, while electricity is also useful but not critical. We recommend both for more convenience.
- You can place several rocks inside the corners of your greenhouse for stability. Barrels or water can also be useful for solar heat. Together they offer great natural benefits to plants while providing stability to the greenhouse.
- Another critical factor is ventilation. It is advised to have at least two vents in the greenhouse in a place where enough air comes inside. This helps to nurture plants effectively.
- Finally, make sure to have proper shelves, so the plants grow well without interfering with other. Try pots and trays that separate the seeds from others, so they don’t have problems while increasing.

Key Factors To Check Before Getting Your Greenhouse
After reading our greenhouse reviews, you may be already thinking about which greenhouse to buy. Yet, we believe you should not pick a product until you learn precisely what to look for.
Here are four factors we think are essential to learning before buying one of these conservatories.
Cover or Glazing
The cover or glazing is the part that goes around the frame. It could be plastic, sheets or glass, solid or fragile, and so on.
While all materials are handy for their own advantages, we recommend polycarbonate as the less expensive, illuminated, lightest and still durable material.
Otherwise, you can go for glass or hard plastic, if you want more heat retention and excellent protection against weather conditions. However, this is eventually costlier.
Another option, you can pick plastic (polyethylene) sheeting covers, which is very useful for illumination and ventilation, comes at a very inexpensive price, but doesn’t last as long as hard plastic or polycarbonate.
The right cover will also help with keeping pests out. If you live in an area where insects may infect your seeds or plants, we recommend going for the enclosed & more protection options such as glass or plastic.
This part will tell you how stable, reliable, and durable the greenhouse is. Doesn’t matter if it is a small or large conservatory, it is essential to have the ideal framework for superior results.
There are several options here, but the most common and the most recommended are powder-coated steel for rust resistance, reinforced steel for durability, and aluminum for lightness.
Here you need to consider several factors at once. But it all comes to the cover and the different features in it. For example, to keep the plants at the right temperature you should have proper insulation.
Heating is vital for several seeds and plants, so going for a hard-plastic or glass option is the best choice.
But this heat shouldn’t be too much either, so it is ideal to have proper shading and ventilation as well. Those covers that have vents or holes where air can come in are handy.
Those that don’t let much illumination in the hottest times of day are also excellent choices.
Apart from the frame, cover, and features for temperature control, other accessories such as shelves, doors, windows, and so on can help you to deliver better nurturing for your plants, easier access to the greenhouse, and more.
Any additional accessory or tool that comes with the greenhouse will probably be useful in the least expected moment, so going for one with any of these will be a good choice.
Do They Work In Winter Weather?
The best greenhouse kits should undoubtedly work even in the harshest of environments. And that means working in winter, spring, fall, summer, and so on. However, winter in the worst places can be pretty bad for plants.
That’s why it is essential to have a greenhouse that allows internal electric heater to function correctly as well as enough protection from the snow load.
If you want a winter greenhouse, it is recommended to go for the hardest and most stable options. But it mostly comes to the additional accessories you use than the design or build of the product.
So, yes, most greenhouses will work in winter as long as you have the right setup and machines to make it work.
What Kind of Plastic To Use?
Large and small greenhouse kits will always come with different types of plastic. No matter the design, you’ll find polyethylene, polycarbonate, copolymer, polyvinyl, and more.
We recommend the hardest and most durable such as polycarbonate for those who want resilience and polyethylene for those who prefer ventilation & natural effects.
Polyvinyl is pretty similar to polycarbonate, yet it offers more illumination and slightly more ventilation, yet not as much durability.
Copolymer, on the other hand, is similar to polyethylene but with a more durable and resilient build.
However, copolymer comes in various options, some of them very costly while offering almost the same advantages as polycarbonate.
What’s the Right Size?
While a small outdoor greenhouse can be useful for someone who has little space in their garden or backyard, a large conservatory will work wonders for someone who has lots of space to use in their house or farm.
So, it’s all subjective and according to the needs of the person. However, it also comes down to experience and enthusiasm.
We recommend the smallest options for beginners or starters who still don’t know how hard it can be to grow seeds or sprouts.
This way, they don’t overdo it and can eventually focus in a few seeds or plants without feeling frustrated if something does not work.
In contrast, if you are an experienced person who already knows what to do and not to do when nurturing plants and seeds, then go for a large one.

What Is PE Mesh?
The best greenhouses out there will come with various different cover materials from polycarbonate to polyvinyl and more.
But we think PE (polyethylene) mesh is the most recommended of them all, as long as you are planting seeds or sprouts that can benefit from a lot of ventilation and sunlight exposure.
This polyethylene mesh is not the most resistant of materials, but it is undoubtedly one of the most useful when it comes to letting your plants receive natural nurturing factors.
With its ventilation, sunlight exposure, and lightness, taking care of your plants will be a piece of cake. But of course, this also means harsh weather conditions may eventually harm the cover.
After reading our the best greenhouse kits reviews and going over our buying guides & advice – you may be wondering which option to go for. Well, we think it’s all about going for the product that best fits your overall needs & requirements.
No point on going for a large greenhouse when you have little space or going for a portable option when you want a stable and resilience conservatory.
So before buying any of these greenhouses, we recommend doing a re-read on each product in the list going over our guides and tips, and make sure to understand completely what having a greenhouse means.
Eventually, you’ll pick the ideal option.
