i am looking to upgrade my lighting from t5's to a t5ho MH combo. i found a fixture (combo light) that im interested in and there is a drop down menu on the order page that lets you upgrade bulbs, fans, and ballasts before you order. the ballast and fan thing i can deal with later, but it comes stock with a 65k 175w MH mogul base bulb. my question is, will 65k be sufficient for a mh fixture? also, the lower the kelvin, the more growth? or is that wrong?
thanks,
Corey
