fluorescent tubes

New fitting are about twice the maximum cost of second hand unit. Only one double fitting can grow many plants until they about 2 weeks old. As they grow taller the light is too dim at the sides and bottom of plant, more tubes will be needed to light these parts of the plant. The light from fluoro's needs to be very close to the foliage about 10cm. max., heat may cause burning or curling of the leaves if there touching the tube. If there are 6 large plants they will need 10 or 12 of 36 watt fluorescent tubes for my cannabis seeds.
