Who do you see as your target audience?
Fellows who want to grow lettuce and have a concrete bunker without a meter on their electricity supply
A house a couple of doors from a friend was rented out, it is in a good area of (South County) Dublin . They thought a nice Chinese family was living there and would wave when they saw them. One day they arrived home to discover the house raided by the police. It had been converted into a grow house. He was in it afterwards and it was destroyed, electricity bypassed, ventilation ducting cut through walls and the ceiling, water from the hydroponics allowed to leak everywhere, it looked as if they just watered the plants upstairs and allowed the water to drip through the ceiling to the plants down stairs. The house had to be rebuilt, just keeping the 4 exterior walls and roof.
