What are the temps in the room? Do you have an exhaust fan at all?

The rooms at about 54c, could u give me any advice on what it should be?

If the room is at 54C then your plants are cooking. Even with added CO2 that is way too hot. Ideally you want your temps to be less than 30C and higher than 20C. You should have a good fan positioned to blow the hot air OUT of your grow space. This may require some ducting work for highest efficiency. You also need some good sized intakes for fresh cool air. If you are having a hard time getting your temps under control, you may want to invest in a small air conditioner and run a duct of cold air directly into your room. That's about all I have. There are some great guides and posts in the forums to read up on so do some more homework and learn from those who have done before.
