Is there a post about about random gear that helps growers? We all post about our lights, air, CO2, AC, humidity, soil, etc, but what about the random stuff that first timers don't think or know about? Feel free to add something to this post that isn't "essential", but has made your grow life easier.

My contribution to the first time DWC grower...transfer pump. Runs on AA batteries and has auto shutoff. Let's you multitask, and saves your back from having to stand there with a bucket.
