Efficient reflection is essential when growing under artificial lighting because of the reduction in light as you move away from the bulb. To achieve this, we offer a material called Mylar, which will reflect over 92% of the light. It can be hung from walls and windows to help maxmise your light output, promoting growth and increasing yields. Sheeting is priced per metre in length and is 1.4 metres wide. Therefore for every 1 metre unit you buy, you will receive 1.4M x 1M of material. 4 metres on a roll £2.50 per metre.
