Cheers for that; itā??s quite interesting! I think I'll go and buy an LED array. They (solar oasis) are claiming 100W HID's/250W fluorescents worth of useful plant light from one ruby bar (that is possible, because most a HIDs light is wasted, whereas no LED light is wasted). If thatā??s true, thatā??s enough light output for my small grow!

The grow shops (in our country) are claiming that LED lighting is not being looked into, as it isnā??t productive enough; someone is not quite right; I just guess it'll cost me 130 quid and a fare amount of hassle to find out.
