If I’m going to be traveling, what is the best self-watering option for my indoor plants (mostly tropicals)? All of my plants are already potted (with a drainage hole of course), so I’m considering the water globes and/or the terracotta spikes with a bottle of water upside down in it. Are either of these good options/best practices? Additionally, humidifiers won’t be running, so curious how long I could be gone without humidity. Appreciate your insights!!
