The revolution of a wicking bed

Everybody loves leafy greens, one of my little ones has taken to wrapping her dinners in lettuce, lasagna in lettuce, zucchini slice in lettuce, "lettuce enjoy lettuce"! Here is a little project Dad and I knocked out last year as part of the SCPA display at the Bega Show. There is no time like now to buy a pack of lettuce seeds and throw them into some fresh soil.

“I am getting allot of bang for the few brass bucks a threw at this one, I have spent $4 and that included the lettuce seeds!”

The bed build is pretty much as you see on the side in the image above. Method Below. Enjoy, Sam.

Wicking Bed


1 x 200L olive oil/poly drum or similar suitable food grade (Local tip $2)

1 x Wheel barrow load of river rocks or similar (discarded job site concrete mix)

1 x Geotech fabric/shade cloth (discard from a construction site)

1 x Load of compost/top soil (soil with composted household waste, horse manure and love grass)

1 x Washing machine centre agitator, 19mm right angle poly fitting, cap, clamp and drainage hose (discarded, road side)

1 x Pack of lettuce seeds $2


Using a suitable saw cut drum in half or two thirds high (600mm height min)

Water inlet, lay old drainage hose in bottom of the drum and extend to the top of drum, add clamp and cap.

Water outlet, at 300mm up from bottom of drum drill a 19mm hole to fit poly fitting

Fill to drainage point with river stones/aggregate

Lay geotech fabric/shade cloth over stones (this prevents top soil falling into stone layer)

Install agitator in centre of bed. (this provides good air flow, potentially works as a worm feeder, also acts as an extra water filling point)

Fill bed with compost/topsoil and plant seeds/seedlings.

Place outside in the sun, water occasionally, observe growth, enjoy fresh greens.
