Hi
I’m interested in trying hydro but have concerns about power outages…sorry if this has been asked before, but does anyone use a Uninteruptible Power Source or other battery type backup to keep thier systems running in case of power outage?
Thanks for any advice 
they have dc air bubbles,sure! look in fishing supply places…
Look up krattkey method… it’s a way to grow hydro without any pumps or anything… you just have to change res more often…
Also I grow dwc hydro and loose power all the time with no major problems … so far I’ve had my power out for 14 hours with no I’ll effects to my ladies… not sure how long the power would have to be out before something bad would happen…
If I knew that the power was going to be out for days I could always throw them into soil as a last resort… 
I have started growing off grid 2kva batteries ah
Solar panels 2kva and wind gen.
45 watt LED
120 w LED
250 W fluoro
300 watt LED is what I’m working with
