Sometimes a little extra ventilation and air flow is needed in small grow cabinets that are used for sprouts, seedlings or clones. When this comes up I like to use a computer fan for this job because they’re easy to hack and easy to find. Below is a video of how I put a fan together without solder. I hope it helps and let me know if you have any questions or comments.
