does anyone know about the T8 tubes

[stinkyattic]

home depot. for a shoplight, that holds 2 T12 lights, its 8.69, ......the bulbs are around 9 bucks each..

Those aren't the bulbs you want. The $9 bulbs are aquarium/plant lights, which are actually not as good for vegging cannabis as the cheap $3-4/bulb 'cool white' t-12s.
