everything is worth trying once.. theres lots of set ups, cheapest probably diy wardrobe/closet grow, or u can prob get a tent at £100-£150 which includes everything, apart from pots n seeds, cfl and leds are cheapest elec wise but hps for better yielsds- that might cause a stir but its good because both sides have creditable points for you to make up your own mind. or outdoors, timing couldnt be better, maybe start them in your window for the min as its still far far too cold at the mo! looking forward to seeing what u decide to do hopefully someone will pipe up on about cfls and with with my comment bout hps having better yields they will prob have a good bit of info for ya.. hps for the win tho
