I have heard of people using 2L pop bottles with a couple pinholes in the bottom and on in the top to slowly let the water drip out. Don't know if it will last the full two weeks though. If you got time until you leave then I would test it to see how long it takes to empty the bottle.

Alternatively you can always set up a pump on a timer but that will cost some money and there is always the chance of mechanical failure or flood.

I wouldn't leave them in hydrogen peroxide.
Perp Reviewed by Perp on . Going Away for christmas vacation!!! Help! hey, I've looked everywhere on the web for ideas for watering my plants while I'm gone for christmas vacation. I'm gone for about 2 weeks. I saw the constant drip mechanism, but I've read that constantly watering your plants causes root rot. is 2 weeks long enough for this to happen. And I was wondein if leaving them in a hydrogen peroxide solution would supply enough water while keeping the roots rot-free (good idea?). any advice would be kool. thx Rating: 5
