u/Dirty_Boots_525

I have two IBC totes placed on a rock wall that’s about 18 inches tall. The garden has a decent slope to it and I’m experimenting with wood chips, sheep wool, and straw for mulch to help retain moisture. I can keep refill the tanks weekly.

My question: how can I add pressure to the lines? I do not have power. Is there a battery or solar pump that I could add that isn’t ridiculously loud? Do I even need pressure if I do drip lines?

Edit for clarity: I can’t raise the tanks any higher without building something substantial, so not a project for this year. Also, the lids are missing so I am unable to pressurize the tanks.
