It's sorted!
i ve been to my local hydro shop and they've got a 125w CFL that will be perfect for my grow box it's about £45 for reflector and bulb (blue spectrum) that's all i'll need for veg stage, then save some money and in time buy the red spectrum bulb for flowering. and just change the bulb when a change the cycle. TA-DA.
I only really asked if a could use those bulbs as i would of started some seedlings from them but i am going to hold off and just buy the proper gear, soil and lighting is where i shouldn't cut back on. i am building my grow box from stuff i can get from work, PLY etc, so total costs so far =£0 (the system)
