wow, this thread is growing like crazy. to be fair, i cant see the garda using a flir to find you out. the only way ud get found out is by telling people you grow. but dont get paraniod about ordering stuff online. ive bought seeds a good few times, lights and a good few enthobotanics, my house should be seriously maked, but i havent been busted yet, and that was all well over a year ago.... as for the esb bill, running a 600w lamp on 12/12 works out at 7.2kwh a day. thats like leaving your heater on for an extra few hours. whats also nice is that cos its getting lighter, ur not using so much on lights, my esb bill went down by 100 last month, so its gonna equal out perfectly with ur lights, the price for last month and the next month should be the same. if ur still mega paranoid, just change all of ur lights in ur house to cfls, u can save round 30% of ur bill from the saving in energy.
