Switched from daily misting to a cheap self-watering spike, my basil stopped dying

Ngl, I spent all last summer watering my 2x4 balcony box every morning before work and still lost half my seedlings to dry soil on hot days. Tried those $4 terracotta spikes after seeing them at a local nursery in Portland, and my tomatoes and basil have been steady for 3 weeks now. Has anyone else had luck with a DIY wicking setup instead of buying the plastic ones?

The soil moisture angle gets all the attention, but the real win with a wicking setup is how it keeps the root zone temperature more even. Misting just wets the top inch, so that water evaporates fast and pulls heat out of the soil, then the roots sit in a cold swing every afternoon. A spike or a wick pulls water from below, which means the whole container stays damp longer and the temp swings less. That steadiness is what stops the basil from bolting or getting that weird bitter edge. Also, the salts from fertilizer don't collect on the surface as bad with bottom watering, so your soil stays healthier over a few months. I rigged a simple one with a plastic bottle and a cotton rope, and it works fine, just make sure the reservoir isn't sitting in full sun or you'll cook the roots. Your mileage may vary, but that temp thing is a bigger deal than people give it credit for.
