the " thing with the tube " is my extractor fan and carbon filter , i use these to keep the smell down , the fan is a ruck 125mm fan and the filter is a Cann carbon filter. as for the soil i am using it coconut fibre with clay pebbles roughly a 50/50 mix, its light and allows alot of oxygen to the roots. i also have the lights on easy rollers and they are a god send , no more chains to worrie about . just going to do the mylar now and i have two intake fans, one for each room to keep the are fresh. don't want to get mold. i topped my plants today and plan to veg for cuttings for about another 10 days or so then put them into 11/13 to find out how many ladies i have
