A greenhouse is a great thing both for hydroponic gardeners as well as those who grow in soil. A greenhouse has the same advantages for either, generally speaking. Nevertheless, hydroponic gardening is particularly appropriate for a greenhouse setting, as temperature, airflow and light are controlled with greater ease.
Strawberries, peas and Welsh onions are a few of the plants that thrive when grown within the confines of a hydroponic greenhouse. Also, flowers such as orchids are great for greenhouse gardening.
Controlling light is something many hydroponic gardeners find particularly challenging. Growth of algae can become a problem since the plant is in water instead of soil. To solve this, you can control how much light reaches the water, something that is simple to do in a greenhouse.
Obviously, just like plants which are grown in soil, plants grown hydroponically also need plenty of light. A greenhouse does not inherently have more light than would an outdoor setting. Because the light is filtered and diffused within the greenhouse, the grower is able to provide a more warm and consistent light for growing. The plants are shielded from reduced temperatures, yet given plenty of sun.
Northern climates in winter will have low temperatures of course, but they do get several hours of full sun per day. A greenhouse wall made from translucent polycarbonate can keep the interior of a greenhouse at 100 degrees Fahrenheit even when it is 15 degrees outside!
You can install vents and fans to keep the inside of your greenhouse from getting too hot; hydroponically grown plants do need a consistent temperature, just as soil grown plants do.
Using a greenhouse opens up many opportunities to make the best of your garden. Some may not have a greenhouse and may choose to grow plants inside the home, but not everyone has the room for that.
Unlike growing in your home, a greenhouse has significantly better light and watering setups. Very rarely do homeowners have the room to run irrigation systems, or install LED grow light panels or metal halide lights just for their vegetables.
With a greenhouse, the systems can be moved where they are best for the plants, making gardening easier for you. This is especially important for hydroponic gardeners, since the water and light are far more important than in soil gardening – a soil garden is typically much better at being self-regulated in this regard.
It is very important as well as easier to set up a feeding system in a greenhouse for hydroponically grown plants. Plants will gain most of the nutrients they need easily when they are planted in good soil. Yet in a hydroponic garden, the gardener must arrange for all of these nutrients to be delivered properly.
Also to be considered, are the pH levels. The pH is able to change with a lot more ease in a hydroponic setting. Acid and alkaline levels can shift rapidly when growing in water. However, in a hydroponic garden a gardener can more easily set up automatic pH controls.
If you do not construct a greenhouse yourself, you can always purchase the one that is already put together. Those who are fascinated with indoor hydroponic gardening will find that their money will be spent well. There are a variety of sizes, with modules that allow it to expand as your garden does.
