New T5 - Quick question

i bought a pioneer 4 foot 4 tube T5 fluorescent and was wondering if that is adequate to veg plants with. will it be slower growth than my old 400mh? also what kinda coverage can i get under that light? i was thinking on keeping 2 mothers under it and maybe some clones or veg plants under it. is it possible? i never used flouros before only mh for veg

T5's work great for veg, They also work pretty good for flower. Just make sure you got the right bulbs for veg.

ya i got the blue spectrum. thanks! but does anyone know what kind of coverage i get with that?

For vegging its not that important unless you are really trying to promote rapid growth then you're better off with a HID.
