veg lighting

[sadhu9]

I have a room devoted to growing. I have a grow hut for flowering and I use the rest of the space in the room to Veg my plants. I use fresh air and an A/C to cool the room and the grow hut when needed. I was wondering if the lighting for the veg plants can be rotated during the day as long as they receive 18 + hours in that day.? I heard that lighting changes can stress the plants out?
I am trying to use the heat from the T-5 lights to help either heat my grow hut when cool out or turn them off to help with the cooling costs.
400+ watts of lighting from the 2 T-5's produces more heat than I thought?!!!! And this can mean the difference between my A/C going on and NOT!!!!! Thanks,

I'm not sure I understand the question correctly. You want to change when the lights are on or off based on the temps in the flowering tent (which is on a strict 12/12 schedule)? This is generally not a good ideal. Try turning your lights on for flower during the night when it is cooler. This will reduce the need for heat at night and A/C during the day. Likewise, you may want to look at using the GLR (Gas lantern Routine) to reduce more of that daytime heat and the power consumption.

Thanks for the reply...I'll just use the GLR which has worked for me.
