Hey grower, yes unfortunately part of growing is having a backup of almost everything since anything mechanical can fail anytime and with hydro, it fails especially fast. It’s really the nature of the beast with hydro. High quality results but a challenging grow process.
I grow in a tent too and have backup tent fans, humidifier, booster fan, carbon filters, light and more. The 2 day shipping has made getting products quick for replacement but I still have a local grow shop that I hit up when the fast shipping isn’t fast enough.
