If you live in a temperate region, then growiing tomatoes in a cold greenhouse is really the only way to ensure a reliable heavy crop of ripe tomatoes. It is really quite easy to grow tomatoes in your greenhouse. You can either raise your own plants from seed, or buy young plants from a garden centre.

If you are growing them from seed, then You will need to start sowing your seed early, probably before the last frosts are over and the best way to do this is to sow them indoors. Sow three seeds in each 3″ pot and place on a well lit and warm windowsill.
Keep your pots regularly watered. Once they have germinated and the worst of the frosts are over, transfer the pots to the greenhouse. Grow them on until the plants are well established in the pots, but before the roots begin to circle in the pot. The soil should be retained by the roots and a god network of root show. Do not leave too long, they will become root-bound and it will be difficult to persuade the plants to let the roots grow further into a new pot. You should then separate the three plants and re-pot each one into a 5″ pot. Grow on like this until they are ready to be potted on again. Now you need to decide how and where you are going to grow them. If you decide to grow them in growbags, then they should be planted no more than three to a grow bag. However, I have found that they grow rather better in deeper pots than a grow bag. One successful technique is to cut a growbag in half and stand each half on end, with one plant in each. This will give you a much deeper root run. You can also grow tomatoes in litre pots in any god soil or compost or in the ground should be so wish.

As you put your plants into their permanent position, consider supports for them. They will want good support up to the roof of your greenhouse. A good way of doing this is to tie a 6ft bamboo cane to the roof of your greenhouse and put it into the pot as you plant your tomatoes.The plants will become very heavy when laded with fruit so canes will need to be supported from the roof of the greenhouse

Tie the plants to the canes as they grow. The sideshoots that grow from the leaf joints should be regularly removed while they are still small. Watch them gro and produce fruit, keeping them always watered. Make sure the plants are watered evenly and that they never dry out. Uneven watering can cause greenback – which makes the fruit go black at the bottom and makes them inedible. If this happens, pick the infected fruit off and make sure the plant it watered correctly. They will usually recover. Tomatoes need about 1 litre (2 pts) of water a day, although cherry tomatoes such as gardeners delight only need 1.5 litres (3 pts) of water a week.This makes the fruit taste sweeter.

When the plants start to flower. spray them with water once a day so that they have humid conditions. You should also gently shake the plant to move the pollen about. After the first truss of fruit has set, you can take off the leaves below it. This will give the plant more air and light so the fruit will ripen faster. At this point start feeding with liquid seaweed. (Tomato feed purchased from garden centre is equally good.). Some people also feed epsom salts because they say that it makes the tomatoes ripen earlier.This has not been proven, and is in any case unnecessary in a diy cool greenhouse.

As soon as the fruits are ripe, pick them, Fresh young fruits are always the sweetest and picking encourage the production of more fruit.

Tomatoes are one of the easiest greenhouse crops and are very rewarding, reliably giving a heavier crop of ripe clean and healthy tomatoes than you could grow outside.

Lighting is a key factor in the healthy growth of any plant. So when you’re planning a greenhouse, it’s important that you give some consideration to the kind of lighting you’ll be using. Selecting a suitable lighting system will ensure that your plants grow faster and remain healthy. Here are various things you should be alert to so as to find the most appropriate greenhouse lighting system for your situation.

1. The first thing you should try to do is establish the quantity of light you will require. The factors you will need to bear in mind are the type of plants you’re going to cultivate and also the size of your structure. Fruits, flowers and tall plants must have more light than some other plants. Greenhouses located outside typically require 25 watts for each square foot. But an interior greenhouse will require no less than two times the amount of light.

2. The kind of light you use must be suitable for the plants you’re growing. The form of light waves that are given off affect plant growth to a great extent. For example, if you are aiming for the the best growing conditions for fruit or flowers, choose high pressure sodium lights. Their light waves are in the red spectrum, and this stimulates the growth hormones in the plants. If you’re cultivating leafy plants, they’ll thrive beneath blue spectrum light waves, which metal halide is better at providing.

3. Your lights shouldn’t make your plants too hot, since this can cause them to die. Some forms of lighting give off more warmth than other types, like incandescent bulbs. This isn’t the best choice anyhow, as the incandescent light isn’t adequate for the majority of plants to thrive. A more suitable option is fluorescent lights, which release significantly less heat. It’s best to check how much heat each lighting option creates before making your purchase.

4. Use lights designed to give good results without eating up substantial amounts of power. High intensity discharge (HID) lights are the most energy efficient kind of lighting available. Sorry to say, they’re also the most expensive to buy. Another option is LCD grow bulbs, which are a common pick thanks to their excellent energy efficiency. Another benefit is that they give off less heat than many other types of lighting.

Whatever the sort of greenhouse lighting you choose, it’s important that you don’t neglect to turn them off from time to time. For optimal growth, plants need a certain amount of darkness. Turn off the lights for 6 to 12 hours each day in your greenhouse, depending on what kind of plants you’re growing.
