I picked up some extra small, battery powered, lightweight fans just in case I needed to add to the Grobo. I don’t know how much cool air the grobo fans will add since they haven’t kicked on yet.
My internal fans are not on yet as I’m only on day four of germ, but noticed the temps are on the rise in the grow box since sprout.
I have pretty good circulation in the room the grobo is located and AC is on most of the year set at 74 (I’ll likely adjust to 70 at some point).
Temps were 80 degrees in the grow box today. So I added these two fans just as a test to see how much air and cooling they’d offer. Light, quiet, battery operated, 4-5 days use on a single charge (tbd), surprisingly push a lot of air.
I’ve added one using the fix-all (duct tape) to the back bottom (it’s not staying there- just a test) and one inside the grow box hanging. Temps were dropped inside the grow box 6 degrees within a few minutes and held after checking 20 minutes later. Hover at 73-74 degrees.
For size comparison
What are you guys and gals using? These were intended for my Disney trip in September, but they’re now property of the Grobo
