I don't know what your light cycle is but lights on during the night when temps are cooler is a good idea and off during the day when temps are usually higher.:hippy:
Greenthing Reviewed by Greenthing on . Keeping temperature down? Hi guys I just built a relatively small, sealed grow box out of a large plastic container. I've lined it with space blanket, cut a hole on top where I've placed my 4" inline outflow fan and carbon filter that I've made. When I close the container, turn the light and fan on, it will soar to about 90 degrees. I want it closer to 80, right? (what temp do you guys normally have?) Any ideas for what to do? For now I'm just leaving the entire assembly open during light cycles and closing it before Rating: 5
