I'm in week 5 going into week 6 on Thursday. Had a little setback on Saturday I thought my bulb popped and it was to late to get to the grow shop and my light cycles start at 8pm on and 8am off so they went that night with no lighting . Sunday I went and got a new light bulb and got it all set up and I'm not getting any power at all turns out it was because my ballast was what stopped working so I set up the t5 for the night and got a new ballast from Amazon over night so Monday I set up the new ballast and bulb and everything is back on track now.
