yeah im sure is a safe site so many uk growers here. am surprised you planning on doing autos as i wood take advantage of the height of the wardrope and the penetrating abiity off 4oo hps. i hear you can do seeds from 12/12 on normal strains and it kicks to flower natural like,just got to do it from day one, also with the savings on electric be a plus. in your set up i wood go for tall plants, also if you do ever get sussed you still have small amount plants so caution only. i hear with the autos alot less yeild unless you find a banging strain. one more thing matey as you do all grow with hps you may want to check out the son t plus bulbs when your current bulb goes. it has added blue spec so helps out with the veg side more then average bulb. good luck with th chopping tomorrow. lucky sod bet your cabbaged as we speak,fair play haha
