Can I make a watering system for my plants while I'm away?

Here's a video that might help - https://www.youtube.com/watch?v=84ZORDdSa60

I used to do this all the time when we would go on vacation. I would set up my plants with a string coming out of the soil from the bottom of the pot and have the string long enough to be submerged into a container of water that would be enough water to last while we were gone. If I could, I would try to prop the pot on top of the container and that way I didn't need as long of a string. The plant drinks itself using this method. This is called a watering wick system. Since then though I have bought those pretty glass balls that you add water to and submerge the pointy end of it in dirt. https://www.amazon.com/Trenton-Gifts-Multi-Colored-Watering-Measures/dp/B07MH67F17/ref=asc_df_B07MH67F17/?tag=hyprod-20&linkCode=df0&hvadid=309807711822&hvpos=1o1&hvnetw=g&hvrand=16466628823390353124&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9007919&hvtargid=pla-623079226982&psc=1

The plant drinks what it needs as well. If you are referring to making an actual pot that is self watering, check out this you tube video: https://www.youtube.com/watch?v=3qlKw70-1XQ. Good luck!

Here is what we did one year when we were away and it worked great https://www.pinterest.com/pin/262756959495379433/

I just shove then in the bathtubs and sinks with a couple inches of water. Depending on how hot it is in your area, that will hold them for 10 days to 2 weeks. Now I have a pet, house and plant sitter for the 6 cats, canary, dragon.

Depends on how long your gonna be gone. I would make some of the recycled 2 litre bottle waterer.... https://www.youtube.com/results?search_query=make+garden+waterers+from+recycled+soda+bottles

I also got a timer for my garden hose that attaches to the exterior faucet. I also have a drip irrigation system that I got for my huge vegetable pots that attaches to the faucet splitter.
