I just got home. 84.5 F in the tent, girls are looking good.Cool, yeah I'm vegging under a T5 I originally bought a 1000w MH/HPS but the 1000W made the room too hot. The T5 was also cheaper than a new ballast and bulb. I have mine still at 24 hr. Going to change them to 18/6 when I get home. I use the same calculator. Are you doing drain to waste or recirculating? My set up is identical to yours and our plants are about the same age ..good shit !
I've been on 18/6 just to reduce power usage. I did have them on 24/0 for a few days I accidentally bumped the on switch on the timer and forgot to put it back to the "timer" mode. Fixed that and ran them for 3 days back on 18/6 before placing in the tent, before going into the tent they had been under 2' T5's from HTG Supply
The 250W is a good light for the girls I found an electric ballast & light for $120 shipped on Ebay.
During the evening once the light shuts off the temp goes from ~ 85 to 76. I have the light & axial fan on the same timer because once the light is off the 190CFM exhaust fan & passive intake is more than adequate.
