Similar to humans, plants are up to 85 percent water. Water is what supports the form and shape of the leaves by what is called turgor pressure. Wilting is what happens when plants don’t receive the necessary amount of water. Water is also necessary in feeding the plants. Fertilizer compounds in the soil are carried to the plant’s root system by water.

Transpiration occurs when big amounts of water are sucked into the plant through the roots and are eventually released into the air through the leaves in the form of water vapor. The warmer the temperature is, the more transpiration and evaporation occurs. For the same reason people drink more liquids on hot August days, plants will also need more watering as conditions demand it.

Knowing when not to water your plants is just as important as keeping them hydrated. Wilting occurs when plants don’t get enough water but plants will also literally drown if they get too much water because they’re unable to get oxygen. Knowing the balance between not enough water and too much water is a big part of growing healthy, good looking plants.

You may be over-watering if the plants’ leaves are yellow or a light green, the leaves are browning at the tips, the roots are sparse or the roots are soft and mushy. You may be under-watering if the plants’ new leaves droop, the soil is dry and dusty or if you take the plant out of its pot and the root system is dry.

Moisture sensing devices can be bought to help track when plants need water and when they’ve had enough. Sensing devices are often set up directly to the watering system so work on your part is minimal. The device will either start or stop an electrical current to the moisture reading. If the water in the soil is insufficient, the sensing device turns on the watering system. There are other sensing devices that control watering by the evaporation rate. Thermostats and humidistats together can also provide accurate water balance. While sensing devices can make your gardening life a bit easier, it’s important to put your experienced judgment first.

If you have pots that don’t have draining holes, insert a tube or a piece of wood when watering; then water until the end of the piece of wood is wet and then water again when the top inch of soil is dry to maintain water balance. With pots with draining holes, water thoroughly and let the water drain out, then water again when the top inch of soil becomes dry.

Many gardeners feed plants with tap water without thinking to check the temperature without realizing that a plant’s soil solution is generally 60 degrees or higher and that the water from the tap should be about the same. Most tropical plants will not be able to handle the cold water and will go into shock and possibly destroy small root hairs and stunt growth. If your greenhouse has piped water within it, you can run it close to the heat source in order to warm the water or wrap a heating cable around the hose for the same outcome. If you use a sprinkling can, simply run the water until it feels warm to the touch before watering your plants.

Misting and Misters

Your greenhouse can vary in temperatures during the day. To lower the temperatures in the greenhouse it can be important to use various types of ventilation and shading to lower the air temperatures.

Airflow through the greenhouse moves the hot air up and out of the vents using the natural breeze. If you live in an area where the breeze does not happen often, fans can be used to push the air and move the hottest air up and through the vents of the greenhouse.

Shade clothes or blinds of some type in the greenhouse will keep the levels of sunlight from hitting the interior of your greenhouse, which will lower the temperature in the greenhouse somewhat as well.

But even with the best ventilation systems, and the use of the shade cloth you can often find your plants are having a difficult time growing and thriving in the greenhouse. Why? Because the temperatures are still high, most likely over eight degrees during the day, the soil that the plants are in dries out faster. The plants need something a little more to keep them cooler and moist while growing.

Using a misting system in the greenhouse will help lower the temperatures in the greenhouse and add the humidity which some plants need. A misting system is going to put out the finest, smallest drops of water possible. A mist is what you will find in your bathroom after taking a shower, sometimes a little heavier than that.

A misting system in the greenhouse will be attached to the roof of the greenhouse but on the inside so the water can float down onto the plants. If you have a powerful mister, you can have it sit in the middle of the floor and spout water upwards and into the air to float down and land on the plants.

Most gardeners are going to prefer a misting system that is on a timer so that you don’t have to leave the water on and then go back to the greenhouse to shut it off periodically during the day. A time is going to turn the water on for just a few short moments, and then shut it down, several times a day. This is a reliable system to ensure your plants are cooled, moist, and taken care of even when you cannot be in the greenhouse.

How to choose the location for your greenhouse

A greenhouse must provide a proper environment for growing plants. This can be done only if proper greenhouse kit is used in building the greenhouse. Planning is important before a greenhouse is built. Greenhouse should be located in a place where it gets maximum sunlight. The best and foremost choice is south or south-east side. Early morning sunlight is the best light for the plants. In order to provide early morning sun light greenhouse should be built in south-east side. North is the best place for the plants which require very little sun light. The personal preference of greenhouse dictates the choice to be considered.

Next point which should be taken care while building a greenhouse is to provide a good drainage. Build the greenhouse above the surrounding ground so that rain water can be easily drained. Oak or maple trees should be placed near the greenhouse so that it can effectively shade the greenhouse from afternoon summer sun. During winter we should maximize the sun exposure on greenhouse.

Water should be manually supplied for the greenhouse plants. Now-a-days a variety of automatic watering systems are available. Such kind of watering systems can be effectively used. Small greenhouses will have a variety of soil mixes that need different amount of water. To control automatic watering system time clocks or mechanical evaporation systems can be used. To provide humidity or to moisten seedlings mist sprays can be used. To water plants in flats, pots or benches watering kits can be used.

A greenhouse kit makes your job easier in growing and maintaining the greenhouse. Before choosing a greenhouse kit few things to be taken care are budget, climate and maintenance. If you find the perfect greenhouse kit for your region then you can grow fresh and healthy plants throughout the year. The first and foremost consideration for choosing a greenhouse kit is climate. Greenhouse kits may vary for different climates. You can use less expensive greenhouse kit if you’re staying in the southern or western states.

You have to choose polyethylene or glass siding if you live in eastern states or Midwest. If you stay in extreme cold climate like Northern states then you need a greenhouse kit which utilizes glass siding, climate control accessories and good insulation on doors and ventilators. These types of greenhouses are the most expensive greenhouse.

Ventilation is another important factor for greenhouse maintenance. Air moment alone is not enough during the summer. Sometimes the light intensity may be too high for the plants. Fans and exhaust fans must be used for this purpose.  The other measures which can be taken during summer are shade cloth, evaporate cooling and paint. For shading the greenhouse roll-up materials, aluminum, vinyl netting or wood can be used. To increase the humidity and cool the air small package evaporative coolers with cooling pads can be used inside the greenhouse. Moist and cool air enters the greenhouse through coolers and heated air passes through roof vents or exhaust fans. When humidity of the outside air is low then the evaporative coolers inside the greenhouse works the best.

Factors to consider before building a greenhouse

Gardening is becoming popular as a hobby as its an affordable and relaxing activity to have as a hobby. Greenhouse gardening is increasingly popular and a major reason for it is that its easy to maintain a greenhouse garden. There are multiple benefits of having a greenhouse garden. One of key benefits of a greenhouse garden is that you can have an extended growing season which is much more than the traditional outdoor growing season. Greenhouses provide a warmer climate for the plants so you may be able to even grow plants which may not survive in the cooler climates of outdoor gardening. With outdoor gardening you have no control on the climate and temperature, but with a greenhouse garden you can easily control conditions such as such as temperature and moisture.

Greenhouse gardening has multiple benefits but you can’t succeed with it without proper planning. You need to take a few factors into consideration before starting a greenhouse garden of your own. Here are a few factors to consider before having a greenhouse:

1) Size of the Greenhouse
When planning to build or buy a greenhouse for your greenhouse garden you should consider the size of the greenhouse that you want to have. The size of greenhouse that you require will depend on a number of factors, but the most important factor to take into account is the type of plants that you plan to grow in your greenhouse garden. I would highly recommend to have a bigger greenhouse compared to a smaller one. If you can’t fill up all the space with plants in your greenhouse garden you can use the extra space to store your gardening tools and supplies which will help you make the most of your time you spend in your greenhouse garden.

2) Water System
Many new gardeners prefer using a hose to water their plants inside their greenhouse, but a greenhouse should ideally have its own watering system. You night need to consistently sprinkle water  on your plants to maintain the moisture and water  that the plants requires inside a greenhouse garden. So you should consider getting an internal water system set up for efficient functioning of the greenhouse garden.

3) Heating and Cooling Systems
Another important factor to consider when setting up a greenhouse is a heating and cooling system. This is really important as they help maintain the optimum temperature of the greenhouse to help in growth of the plants. You should also set up a thermometer inside the greenhouse to monitor the temperature. Remember that without a proper heating and cooling system in place the plants can end up dying in greenhouse garden.

4) Design of Greenhouse
Greenhouses are available in various shapes and sizes and you should select one that best suits your requirements. It also depends on your personal preference and the plants that you wish to grow in your greenhouse.

Greenhouse gardening can involve significant up front investment but you can reap great benefits in the long run. You will get to grow various varieties of plants which you might have never grown in a traditional outdoor garden and also gain a great and unique gardening experience with a greenhouse garden.
