I have a nice light stand, it is 6ft Tall. 4 ft long, and each shelf is 18 inches wide.I have acquired some twin tube 4 ft 32W T8 shoplights. there ONLY 5 inches wide reflector to reflector so I need to use TWO of these twin tube T8 32W 4ft fixtures PER SHELF to allow even light coverage. If I just use one of these fixtures because my shelf is wide it is very dark to the plants. Now my question is this: What type of light bulbs should I buy that will give me maximum growth and bloom? I have used a combination of warm white/cool white with very mediocre results... im leaning towards using either all 5000K tubes or all 6500K tubes. I have read tho of some people using 6500K tubes only for AVs only to have their plants grow vertically. so maybe a 5000K tubes might be better?
at my local home depot they sell daylight DELUXE by phillips which is rated at 6500K (deluxe means they have a BIT of red light in it-that helps promote flowering). they also sell I think its called office light by phillips (Rated at 5000K) so I need your suggestions from any of you who grow African violets SUCCESSFULLY using ONLY T8 32W 4ft tubes. should I use only 6500K tubes OR only 5000K tubes?
