|Three weeks is a long time so if you can't have a neighbor check on them you can try grouping the plants together (to keep humidity high) and using plastic water bottles as a source of drip irrigation. Be sure to try using them before you actually go on vacation, just to make sure they deliver enough water to keep your plants growing well. Water the containers well first, then fill plastic liter bottles with water and turn them upside down with the open tops buried into the soil two or three inches. Capillary action will draw the water from the bottles into the soil. Test to see how many bottles your plants will require to keep the soil reasonably moist. Good luck with your plants.
