I tried cauliflowers in the past but they all got destroyed by cabbage flies. I heard that you can simply add nets over and around but I am a bit too lazy to do this haha

The self-watering is pretty straightforward - just a battery-driven valve, a lot of hoses and a drip irrigation kit.

My garden is a 15 minute drive from my home so it helps me a lot!
