This lettuce started out in the yard and will growing on its own from last years garden. We took it sorry 4 leaf self and put it into this system and in 2 weeks it bolted up to this. Sorry to say we have eaten this puppy. I couldnt get to the wife fast enough to stop her from wacking it all off at the base. I thought I heard murray say on one of his videos you could just trim it back and get about 3 runs on it????
