I bought a t5 housing setup last year. A couple of days ago the bulbs seem to have blown out. I replaced both with temporary 4100k 54 watt bulbs until the local hydroponics store opens up on the weekdays where I can get proper 6500k bulbs. The temporary 4100k bulbs are still flickering. Now figure it's an issue with the actual housing. Does anyone have any thoughts? Will I need to buy a new housing? Thanks!
