Ssdrum's First Bucket

Hey all, I found r/spacebuckets about 3 years ago, and am finally able to make my own! I've been (for the most part) following u/mcscroggins' Blackout  Space Bucket guide, which has been incredibly helpful, but I do have one question: In using the Apollo LED grow light, which has an exhaust fan on the back, do I still want to use two PC fans, or is that a sufficient exhaust? 

I've added a second PC fan just under the light as an exhaust which has helped lower temperatures, and added a small dish of water as a temporary means of raising humidity, as well as adding 2 more spacers to give it additional height. 

Thanks again to everyone who's contributed to r/spacebuckets, you've helped immensely.
