ive had good luck with
hortilux...
had good luck with generic no namers.
cant recall too many, actually, that didnt work to, at least, a decent horticultural standard.
i suppose as long as the bulb emits the intensity and the color spectrums youre looking for it really dont matter, right?
i never really had a bulb (in the past 10 years or so) that didnt do the job....
so thats why i said the above statement.
im sure theres farmers here more in tune with lighting and can give you a more descript answer, but, thats a short answer to ponder in the meantime.
