I found that after 28 years in the Infantry grow rooms are a lot like fighting positions... you keep coming up with ways to improve them. Light decipline, remember to cover up all those "power indicator lamps" on your power strips, timers and heater/dehumidifiers. They can put out significant amount of unwanted light during the dark cycle. I rigged up a separate circuit for a green tinted CFL just in case I need to enter during the dark cycle. It is also wise to keep in mind is you can set your light cycle during the evenings during the summer time which means having to use your AC less during the
day. You can also buy fan controllers that are temperature controlled so that in winter the fan will run slower allowing radiant heat from the lights to help keep your grow room warm and of course run faster during summer nights. Your flowering cycle will also provide your home with a lot of fresh
bud aroma... I get crap for this, but I always keep a bag of pop corn in nearby microwave oven during trimming operations, the smell of popcorn will
eliminate the odor of weed and as you know lingers for a day easily. Of course after firing up a bowl the popcorn comes in handy
