What to Look For When Buying an Indoor Greenhouse

When buying an indoor greenhouse, your mind might probably first go to its size and your house’s capacity to store it. Although that’s a very valid factor to consider, there are other details that shouldn’t be overlooked when shopping for this item. Read on to find out:

Material 

There are many materials that can be used to build an effective indoor greenhouse such as PVC fabric, fiberglass, polyethylene, polycarbonate, etc. If you’re looking for a more durable material that will withstand snow and cold climates, PVC fabric is your best choice. Another benefit to this material is that it is easily set up and does not require special skills. For a more durable material, fiberglass is your best choice since it can last up to 10 years. The only problem with fiberglass is that it is sensitive to UV lights so you will have to apply a new UV coating every couple of years.

Ventilation 

Ventilation is another important feature to have in an indoor greenhouse. Of course, it is important for the plants and vegetation to be insulated especially during the cold seasons, however, without ventilation, your precious plants might cease to exist. The moisture and humidity need an exit area and that exit area should be roll-up windows and doors. So when buying an indoor greenhouse, make sure it has more than one enter/exit area.

Shape and size

You may want to consider the appropriate greenhouse size according to the plants and vegetables you plan to have. Obviously, the size will also depend on how much space you have. If space is not an issue and you’re trying to decide between two options, we suggest that you pick the larger one. You’ll always find yourself wishing for more space; as your love for gardening will grow, so will your greenhouse.

Conclusion

Keeping your plants and vegetables healthy is a year-round job, and there is no excuse during harsh seasons: these amazing indoor greenhouses make sure you can succeed at gardening any time of the year. Plus, they can be a great sleeping spot for your cat!
