Hi Wooman. I live also live in the Uk and have a nice little crop of Northern Lights on the go. I am not using any special lamps, hydro-thingymajigs or any of that other fancy stuff; just water, feed, music and love. They seem to be getting on just fine!
Please be VERY careful about growing!! THINK SECURITY!! Do NOT tell ANYONE, this includes brothers/sisters best friends or anyone else you think you can trust. Please believe me! You only get one chance and then you're in jail!
