Grolux (Plant Growing) Continued

As a specialist light source the Grolux Fluorescent Tube emits a high level of red and blue radiation that promotes healthy plant growth in areas with insufficient daylight. To this end this lamp is commonly used in appropriate fittings in horticultural applications such as greenhouses, conservatories, indoor gardens and florists. Grolux lamps are also used for the artificial lighting of freshwater aquariums strengthening the colours of aquatic plants and fish. As an energy efficient light source these fluorescent tubes will last up to 10,000 hours, are very affordable and reliable with a proven track record of performance.

Good Range, Convenient and Quick
I have used this site a number of times and have always had excellent service. They have usually got what I want, prices are good and delivery speedy. When I first used it, I was concerned the bulbs would arrive smashed. Not a problem. Never had a damaged bulb. Due to my own failings, I have never yet used their 5% off discount vouchers they send with your order. I always remember the vouchers just after I have placed the next order! Don't forget to use yours.
