thanks for trhe help mate.I had to take my last room down but i rebuilt it he same as i said only diffrence was the change from a a small shitty fan to a £150 one lol (dearest aint always the best haha).,As for water consumption well the last crop i lost well believe it or not i was giving them about a litre\and a 6 days later they were still heavy.all they did was get worse every day.So now i have started again and put my clones under a 400watt for 18hrs there about a foot tall.I'm just hoping they come good.
