First I purchased a light meter which are available on the internet and from garden centres costing less than \u00a310.<\/p>\n<p>I soon discovered that ordinary <strong>tungsten<\/strong> light bulbs don\u2019t emit enough rays to help my plants. However a 50 watt<strong> halogen<\/strong> spot lamp made a lot of difference. So did fluorescent strip lights in the kitchen. After a few days it\u2019s possible to notice the plant growing towards this new source of light.<\/p>\n<h2><span style=\"font-size: 12pt;\"><strong>Artificial Light<\/strong><\/span><\/h2>\n<p>Next I researched hydroponic lights finding a bewildering array to choose from, with it becoming clear many are unsuitable for domestic use. A normal household bulb uses up to 100 watts (w) of electricity per hour. Some specialist hydroponic lights use 600w and 1000w bulbs. These need a transformer like metal control box which is both heavy and gets extremely hot posing both a fire and injury risk. I didn\u2019t feel they were right for my home and more appropriate for commercial horticulture.<\/p>\n<h3><strong>Citrus Tree<\/strong><\/h3>\n<figure id=\"attachment_2520\" aria-describedby=\"caption-attachment-2520\" style=\"width: 300px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/the-news.uk\/wp-content\/uploads\/Greenfingers-9-3.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-2520\" title=\"Greenfingers 9 3\" src=\"https:\/\/the-news.uk\/wp-content\/uploads\/Greenfingers-9-3-300x260.jpg\" alt=\"Indoor Citrus plant being illuminated by a bright CFL\" width=\"300\" height=\"260\" srcset=\"https:\/\/the-news.uk\/wp-content\/uploads\/Greenfingers-9-3-300x260.jpg 300w, https:\/\/the-news.uk\/wp-content\/uploads\/Greenfingers-9-3.jpg 533w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-2520\" class=\"wp-caption-text\">Lemon tree basks in winter light<\/figcaption><\/figure>\n<p>I bought a Maxibright 250w<strong> Compact Fluorescent Lamp<\/strong> complete with all fittings for \u00a380 which proved simple to rig up in my kitchen. A time clock switches it on for four hours a day between 10am and 2pm to augment the limited winter natural daylight, and is enough to help the lemon tree flower in December. A kilo watt hour (kwh) costs around 15p, so for five months until the sun appears over next door\u2019s roof\u00a0 the electricity is cheaper than buying replacement plants in the spring from the garden centre.<\/p>\n<p>As soon as the shortest day is past, the artificial light should be left on an extra 30 minutes a week bearing in mind in gets lighter between December and June at an approximate rate of two hours extra a month.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By William Mills &nbsp; &nbsp; \u00a0Indoor Gardening In my house the last sunlight reached my backyard in early October with no more expected until March in the early spring.
