Thanks again! That helps me out big time. I was worried I had to have fresh air and not just for temp purposes. I know the buckets of co2 boost are expensive but would it be worth hooking up a couple of buckets and the the fans blow on the plants? I have an all electric house and in no way could I use a generator. I was told co2 is co2 and id doesn't matter where it comes from but I still need to know if there is a way to monitor if they are getting enough.
bigbud751 Reviewed by bigbud751 on . Question about sealed room with no outside air? OK guys, please help me with this. I have a 6X15 room and 4 1k lights are going to be installed. I will be usin a fan from outside and cooling the lights through a 6" duct to the outside. I will use a can 66 filter, dehumid and fans inside the room. My questions are: Will the heat from the lights still be too much for that size room w/o an a/c? If it is sealed do you have to have fresh air or can it keep using air from the room through the can filter? If it does stay cool enough Rating: 5
