Grow lamps were once massive, power-hungry, expensive and hot. Meet the amazing new LEDs

As a self-confessed science geek I am fascinated by technology. Yet in the world of gardening this is often synonymous with the gimmicky (fibreglass meerkat solar light, anyone?) or the hugely complex and costly – think hydroponic growers that require a degree in electrical engineering to install. So it was with trepidation that I started experimenting with LED grow lights last winter in my tiny flat.

Growing plants with artificial lights offers a great range of opportunity when it comes to growing plants indoors. Plants in different stages of growth have special lighting requirements in order to flourish indoors, and it pays to understand their lighting needs in order to meet them and get the best from your plants.
