Maybe you didn't read a portion of the posts; but i would be a hypocrite to blame you, so i will state this.
I am 13, i can't go and buy things, and my parents aren't the kind to take me to home depot over and over and over, so i basically need to mcguyver this, a watering system that will get my plants through a week- im going on vacation in February, and i'm going to receive a ventricosa in a few days, and i don't want it to be shipped cross country, to be meet by re potting and drought. It will stunt the plant, and i don't want that to happen. So, using seltzer bottles, straws, and other household materials, i will construct a drip system to get my teeny tiny plants through the week, eventually i'll save up money for a real project. I'm at a few hundred dollars, which i'm willing to spend.
