growing soil . Pots . perlite , vermiculite , Ph tester , PH up & PH down , Nutriants , Hps light . Myler sheeting , Ocilating Fan . Extractor Fan , Vegging light , ie , florecent strip lights , or Cfl`s but ive never used them , So once your mate has spent £150 thats without the price of the hps , With a hps light your talking another £80-£100 you`ll be good to grow . Happy shopping .
By the way you`ll also need a temp/humidity reader , they can be cheep like £5, I paid £45 for mine but it tells me the lot and its also wireless so i have one part in grow room and the main reader anywere i want so i dont even have to go to my grow room to check temp i can be just anywere within 100mtr and get a reading of my room temps and humidity . Im pritty smashed @ the min and rambling on while listening to Eastenders . Go and spend some cash and grow well or dont grow @all . ROTFLMTO ,
Ps , dont know why the fuck no one else could of given you the basic ,
