zino11 Reviewed by zino11 on . Ventilation Problems So I am a few cycles through, having a problem for the first time here. I live in Nothern California and have not have temp problems since I started growing. That was until four days ago. I had the babies comfortable under 1000 watt lamp, but I transplanted and had to turn on the second 1000 watt lamp and my temps in the canopy are hitting as high as 92 degrees. This is a huge suprise to me because the house is very chilly usually, heck I had to run a heater over the winter to keep my temps Rating: 5
