Good luck with your bucket! I've never been one to understand the bucket route, but each to his own! You should grab some old PC case fans and any old phone charger. Wire them up, and insert one blowing in near the bottom of your 'top bucket' and one blowing out near the top. Without proper airflow, you will heat stress the plant to death.

@TrilliumTrichomes, while i would love a full tent setup it is not an option right now, i have an inline fan cranked to the max on the spacebucket, couple inch wide passive intakes at bade of the bucket, i dont think airflow is the problem as much as the ambient temperature is, the room also got upto 40 degrees yesterday, need an air con. Thankyou :)
