Hey I am using a 400 watt hps light. I am using Foxfarm ocean forest soil in 5 gallon pots. For nutes I am using Foxfarm organic tiger bloom nutes.Along with foxfarm big bloom. I am also using maxicrop liquified seaweed extract. I have got a small oscillating fan in the room for circulation and two fans set up for exhaust.
Too be honest I was checking the temp when I first started But now I dont do it anymore. I don't have any type of temp control system. Now that the days are warming uparound here it gets to like 80-82 degrees during the day. And I am kind of guessing on this but around 60 degrees at night. I leave my window open and an extra fan in my room for circulation.
