Here we have prepared a questionnaire to answer some common questions.
What is the best greenhouse design for hot climates?
We recommend a greenhouse that has plenty of ventilation for use in a hot climate. One with easy to open sides so that the structure will have good air flow. You may want to consider a greenhouse that has open sides that are covered with insect netting if you live in a hot climate.
How can I heat my greenhouse cheaply?
Using solar panels to harvest the energy of the sun will be the cheapest way to heat your greenhouse. The number of solar panels needed will depend on the size of your greenhouse.
Another cheap method for heating a greenhouse is to place black plastic bottles filled with water inside the structure. The black plastic will absorb heat and warm the water inside of the bottle and raise the temperature of the greenhouse.
What material is used for greenhouses?
The greenhouse frame can be built from wood or metal. The covering should be clear or semi-clear plastic or glass. The plastic can be sheeting or rigid acrylic panels. The goal of the covering material is to allow as much sunlight as possible to enter the greenhouse.
Which vegetables are easy to grow in a greenhouse?
For beginners, we recommend easy care plants like carrots, onions, kale, zucchini, turnips, and eggplants. Herbs are typically easy to grow in a greenhouse too. An experienced gardener may want to try growing tomatoes and cucumbers.
