Yes! There is a large circular cap on the inside of the garden bed. The cap can be easily removed, and the internal water reservoir cleaned and flushed out with a hose. We recommend this be done while the garden bed is completely empty. See manual for more details.
Harvi has a reservoir that sits in the bottom of the garden bed. It can be filled directly or with excess water from rain or watering. Water from the reservoir moves through holes into channels where the capillary mat sits, pulling water from the reservoir to plant roots.
Filling the reservoir can be done by putting water directly into the holes on the top rim of the garden bed, excluding the four corner holes. You’ll know that the reservoir is full when water begins to trickle out of the overflow nozzles on the bottom of the bed. Harvi’s reservoir can also be filled by watering over the top of the soil and letting the excess water run down and settle in the bottom.
Drainage largely depends on the soil used. The addition of small pebbles or sand may help, but make sure that those growing media will work for the plants in your garden. Check with your local garden center for more tips!
