That only helps to remove heat build up from the light. It will only save you about 7-12 deg f on the average. That's important because it allows you to get your light closer and increase the lumens to more area if your plants. You still need to keep the room with in the proper temperature range.

A/C units lower the humidity so you need to have a fogger and hemostats to keep the RH at the proper level. Cool temperature is as important as the RH level of the room too. They go hand in hand in maintaining the health of your plants.


Hey Harddon - It's not a bad thing your plants are drinking 1.5 gallons a day but if you keep the temperatures lower and the RH high they would not need to drink as much. Drinking more water gives them more nutrients too. The trick is to balance the environment so they can use up the extra nutrients and process them into larger branches and more buds.
