Here are all the different watering systems we started with.
This is lengths of rope through a hole in the bottle, the end weighted down with nails. I half buried the bottle to keep it in place. I ran the rope just under the ground around each seedling.
Update: this system is working really well with the ropes constantly damp. Next time, I'd put the ropes straight down into the ground so the roots get the water.
This one is stips of cloth which isn't working so well because each strip gets dry. I covered a similar one with a larger bottle lid and cut out areas where the strips run.
This one works on evaporation. Inside is an upturned half bottle filled with water. The water evaporates inside and runs down the sides. This isn't working that well as there isn't really enough water being evaporated. We changed it slightly and put a cut water bottle covered in black tape. It's better but still only surface water.
This one is a plastic bottle buried upright with holes poked in the bottom. The water drained out too fast! Even with the lid on. An improvement would be smaller holes. This one is cloth strips flush against the plastic bottle and is working well. The strips stay moist although and the plants seem to be OK. My ultimate favourite. The plants around the olla are doing well and the water lasts quite a few days. It's a little fiddly to fill up the ones with smaller holes as it needs a very small funnel or a super careful aim from the watering can.
And with that the garden started growing 😊
